SB2C Helldiver - Curtiss SB2C Helldiver

SB2C Helldiver - Specifications: General Length: 36 ft. 9 in. Wingspan: 49 ft. 9 in. Height: 14 ft. 9 in. Wing Area: 422 sq. ft. Empty Weight: 10,114 lbs. Loaded Weight: 13,674 lbs. Crew: 2 Number Built: 7,140 Performance Power Plant: 1 Ãâ€" Wright R-2600 radial engine, 1,900 hp Range: 1,200 miles Max Speed: 294 mph Ceiling: 25,000 ft Armament Guns: 2 Ãâ€" 20 mm (.79 in) cannon in the wings, 2 Ãâ€" 0.30 in M1919 Browning machine guns in rear cockpit Bombs/Torpedo: Internal bay - 2,000 lbs. of bombs or 1 Mark 13 torpedo, Underwing Hard Points - 2 x 500 lb. bombs SB2C Helldiver - Design Development: In 1938, the US Navys Bureau of Aeronautics (BuAer) circulated a request for proposals for a for a next-generation dive bomber to replace the new SBD Dauntless. Though the SBD had yet to enter service, BuAer sought an aircraft with greater speed, range, and payload. In addition, it was to be powered by the new Wright R-2600 Cyclone engine, possess an internal bomb bay, and be of a size that two of the aircraft could fit on a carriers elevator. While six companies submitted entries, BuAer selected Curtiss design as the winner in May 1939. Designated the SB2C Helldiver, the design immediately began showing problems. Early wind tunnel testing in February 1940 found the SB2C to have an excessive stall speed and poor longitudinal stability. While efforts to fix the stall speed included increasing the size of the wings, the latter issue presented greater problems and was a result of BuAers request that two aircraft be able to fit on an elevator. This limited the length of the aircraft despite the fact it was to have more power and a greater internal volume than its predecessor. The result of these increases, without an increase in length, was instability. As the aircraft could not be lengthened, the only solution was to enlarge its vertical tail, which was done twice during development. One prototype was constructed and first flew on December 18, 1940. Built in a conventional fashion, the aircraft possessed a semi-monocoque fuselage and two-spar, four-section wings. The initial armament consisted of two .50 cal. machine guns mounted in the cowling as well as one in each wing. This was supplemented by twin .30 cal. machine guns on a flexible mounting for the radio operator. The internal bomb bay could carry a single 1,000 lb. bomb, two 500 lb. bombs, or a torpedo. SB2C Helldiver - Problems Persist: Following the initial flight, problems remained with the design as bugs were found in the Cyclone engines and the SB2C showed instability at high speed. After a crash in February, flight testing continued through the fall until December 21 when the right wing and stabilizer gave out during a dive test. The crash effectively grounded the type for six months as the problems were addressed and the first production aircraft built. When the first SB2C-1 flew on June 30, 1942, it incorporated a variety of changes which increased its weight by nearly 3,000 lbs. and reduced its speed by 40 mph. SB2C Helldiver - Production Nightmares: Though unhappy with this drop in performance, BuAer was too committed to the program to pull out and was forced to push ahead. This was partly due to an earlier insistence that the aircraft be mass-produced to anticipate wartime needs. As a result, Curtiss had received orders for 4,000 aircraft before the first production type flew. With the first production aircraft emerging from their Columbus, OH plant, Curtiss found a series of problems with the SB2C. These generated so many fixes that a second assembly line was built to immediately modify newly built aircraft to the latest standard. Moving through three modification schemes, Curtiss was not able to incorporate all of the changes into the main assembly line until 600 SB2Cs were built. In addition to the fixes, other alterations to the SB2C series included the removal of the .50 machine guns in the wings (the cowl guns had been removed earlier) and replacing them with 20mm cannon. Production of the -1 series ended in spring 1944 with the switch to the -3. The Helldiver was built in variants through -5 with key changes being the use of a more powerful engine, four-bladed propeller, and the addition of wing racks for eight 5 in. rockets. SB2C Helldiver - Operational History: The reputation of the SB2C was well known before the type began arriving in late 1943. As a result, many front-line units actively resisted giving up their SBDs for the new aircraft. Due to its reputation and appearance, the Helldiver quickly earned the nicknames Son of a Bitch 2nd Class, Big-Tailed Beast, and just Beast. Among the issues put forward by crews in regard to the SB2C-1 was that it was underpowered, poorly built, possessed a faulty electrical system, and required extensive maintenance. First deployed with VB-17 aboard USS Bunker Hill, the type entered combat on November 11, 1943 during raids on Rabaul. It was not until spring 1944 that the Helldiver began to arrive in larger numbers. Seeing combat during the Battle of the Philippine Sea, the type had a mixed showing as many were forced to ditch during the long return flight after dark. Despite this loss of aircraft, it sped the arrival of improved SB2C-3s. Becoming the US Navys principal dive bomber, the SB2C saw action during the remainder of the conflicts battles in the Pacific including Leyte Gulf, Iwo Jima, and Okinawa. Helldivers also took part in attacks on the Japanese mainland. As later variants of the aircraft improved, many pilots came to have a grudging respect for the SB2C citing its ability to sustain heavy damage and remain aloft, its large payload, and longer range. Despite its early problems, the SB2C proved an effective combat aircraft and may have been the best dive bomber flown by the US Navy. The type was also the last designed for the US Navy as actions late in the war increasingly showed that fighters equipped with bombs and rockets were as effective as dedicated dive bombers and did not require air superiority. In the years after World War II, the Helldiver was retained as the US Navys prime attack aircraft and inherited the torpedo bombing role previously filled by the Grumman TBF Avenger. The type continued to fly until it was finally replaced by the Douglas A-1 Skyraider in 1949. SB2C Helldiver - Other Users: Watching the success of the German Junkers Ju 87 Stuka during the early days of World War II, the US Army Air Corps began looking for a dive bomber. Rather than seek a new design, the USAAC turned to existing types then in use with the US Navy. Ordering a quantity of SBDs under the designation A-24 Banshee, they also made plans to purchase a large number of modified SB2C-1s under the name A-25 Shrike. Between late 1942 and early 1944 900 Shrikes were built. Having re-assessed their needs based on combat in Europe, the US Army Air Forces found these aircraft were not needed and turned many back to the US Marine Corps while some were retained for secondary roles. The Helldiver was also flown by the Royal Navy, France, Italy, Greece, Portugal, Australia, and Thailand. French and Thai SB2Cs saw action against the Viet Minh during the First Indochina War while Greek Helldivers were used to attack Communist insurgents in the late 1940s. The last nation to use the aircraft was Italy which retired their Helldivers in 1959. Selected Sources Ace Pilot: SB2C HelldiverMilitary Factory: SB2C Helldiver Warbird Alley: SB2C Helldiver

Women Of The 1920 S 1939 - 1305 Words

Women of the 1920’s-1939 The 1920’s was an era of dramatic political and cultural change, where many Americans lived in cities rather than farms. Many inventors came to be noticed as new cars were invented and as music entered the entertainment industry. A new style of music was invented mainly in the African American community, creating the Harlem Renaissance; which was an evolution of music and entertainment in Harlem, New York City. The women of America began to evolve in the 1920s, adding new styles to our fashion industry and changing the way women dress, act, and are portrayed in society for generations. Women were viewed before the 1920’s as innocent housewives, that made little to no money, as they often relied on their husbands’ for income. Women also had little to no rights, such as voting rights, which many women began to protest. Women of the 1920’s through the 1930’s influenced and impacted society by transforming their looks from innocent housewives to a sexually liberated generation of women, increasing the working rate to twenty-five percent by working in factories and the telemarketing business, and participating in the Women’s Suffrage Movement in which they protested for their rights which then influenced the ratification of the Nineteenth Amendment.

Even longtime readers, though, are likely to happen The Waterworks Doctorow # 8217 ; s strangest and most debatable innovation so far. The scene is New York City in 1871, although the narrative of what happened there and so is told at an indeterminate subsequently day of the month by a adult male named McIlvaine, who notes, at one point in his narration, # 8220 ; I have to warn you, in all equity, I # 8217 ; m describing what are now the visions of an old man. # 8221 ; A figure of similar cautions are interspersed throughout the narrative, and taken together they add another degree of enigma to the point he makes over and over once more: he has been a informant to horror and lived to state the narrative. Which, possibly, begins as follows. As the metropolis editor of the New York Telegram in April 1871, McIlvaine employs a figure of freelance authors, including his most gifted, Martin Pemberton, the disinherited boy of of the late Augustus Pemberton, a millionaire whose decease and funeral had made the documents the old September.

Enterprise Architecture for Strategy and Business Alignment

Question: Discuss about theEnterprise Architecture for Strategy and Business Alignment. Answer: Introduction There are a variety of Information Systems (IS) that are used and implemented in a business organization. These systems need to be adequately configured, integrated, and implemented to achieve the best results out of the same. Enterprise Architecture (EA) is a concept that allows the enterprises to strategically plan and align the information systems and applications with the business objectives. The main objective of EA is to present the guidelines that can be implemented by an enterprise so that it may achieve the business goals and objectives. It leads to quick decision making processes and also streamlines all of the business operations (Rajabi, Minaei Seyyedi, 2013). Enterprise Architects are the resources that are responsible for implementing and managing EA and these resources shall have communication with the fellow operators and team members. Problem Statement The problem with the information systems in an organization is the integration of varied systems and applications with each other along with the issues of data and information management. There are numerous security risks and attacks that emerge because of the loosely integrated systems that are not configured properly. Also, the organizations fail to analyze the information systems that are required by them and implement the ones that are not relevant. It leads to increase in costs and budget of the organization (Bergvall-Kareborn Howcroft, 2014). Enterprise Architecture is a concept that addresses all of such issues that are associated with the information systems installed in an organization. Policies Processes Enterprise Architecture amalgamates the description of the best applications, strategies, technologies, and procedures that an organization shall implement along with the integration mechanism between these elements. The current organization has defined a modeling language as a standard for all the units of the organization so that coherent architecture is put in place. There are specific complexities that are associated with each of the information system and application that is installed in an enterprise. The modeling language and foundations assist in the resolution of such issues. EA models ensure that the integration between the components is adequately done and the relationship is also covered well. The architectural practices and processes are highlighted as an outcome (Kappelman Zachman, 2013). Communication between the information systems installed in an organization is a significant need to achieve the benefits. Also, it is required that the internal and external stakeholders along with all of the resources engaged with an enterprise maintain enhanced communication levels with each other. The organization has implemented communication strategies and methods as a part of EA to strengthen the communication between the resources and stakeholders. There are architectural models that have been implemented to manage the current activities and assess the future events for detailed analysis. There are as-is and to-be scenarios developed for this purpose (Lankhorst et al., 2005). Stakeholders are the entities that are associated with a business organization implicitly or explicitly. The primary goal of an EA is to ensure that the needs of all the stakeholders are met and the engagement and satisfaction levels are enhanced. The information systems that are implemented in an enterprise are done with an objective to fulfill the customer and stakeholder needs (Iyamu, 2017). The Enterprise Architects and the stakeholders connect with each other to determine the scope of each of these systems. The absence of the same will lead to poorly defined scope and deteriorated satisfaction levels of the customers as well as stakeholders. The organization has defined a number of different viewpoints so that the social relationship between the stakeholders and the architects is defined adequately (Rozanski Woods, 2007). Functional Viewpoints: The functional requirements and aspects of all the information systems that need to be present in an EA are targeted and are mapped with specific stakeholders and architects. Information Viewpoint: Each of the information system that is configured for an enterprise comprises of the data and information sets of varied structures and types. There are specific methods and procedures that are implemented to handle such varied sets and are covered in this viewpoint. Concurrency Viewpoint: The concurrently occurring processes and methods are targeted under this viewpoint. Development Viewpoint: The development of one information system is different from the other and it depends largely upon the development methodology that is used. The viewpoint includes the varied developmental methods and tasks that are carried out for the information systems that are present in an EA. Deployment Viewpoint: The environment which will be used for the deployment of the IS and EA are included in this category. Operational Viewpoint: There are a variety of operational tasks and activities that are associated with each of the information systems and the same are targeted upon in this viewpoint. The viewpoints that have been listed are then mapped with the architectural perspectives and the association and relationships are drawn out as a result. The assessment of the requirements and needs of the stakeholders and the end-users is done with the definition of the functional specifications, scalability needs, system capabilities and qualities. The demands of the stakeholders and the users may vary constant and it is therefore necessary to ensure that the system flexibility and scalability is always maintained. There may also be other issues that may be involved in the modification of the system aspects (Kotusev, 2017). For instance, the increased development time associated with the information systems may lead to the change in the system scope along with the modifications in the architectural design and principles. The demand of each of the information system also varies in terms of the architecture, environment, technical requirements etc. For example, one of the information systems may perform better in isolation while there may be other system that may require enhanced level of integration. EA ensures that the adequate functional structure and design is prepared and implemented for each of the systems and the viewpoints of each are also defined clearly (Pirta Grabis, 2015). Adequate management is one of the necessary activities that play a significant role in the information systems as well in the Enterprise Architecture. There has been a lot of research that has been carried out in the management aspect of IS and EA. However, a common understanding has not been achieved yet. There are practically oriented research methodologies that have been defined to integrate the management tasks with the architectural, technical, and functional aspects of the systems. The development of such a theory is not sufficient. It is necessary to implement the same as per the feasibility of the system and the organization as whole (Simon et al., 2013). As a result, there are only handfuls of methods that can be actually implemented to achieve the desired results. The issue of inadequate planning is very popular among the enterprises as the management does not pay much attention to this particular aspect. However, planning is a necessary activity that shall be carried out a s a mandatory step (Masuda, Shirasaka, Yamamoto Hardjono, 2018). Security is another aspect that has been carefully and adequately planned and implemented in the EA. There are several risks and attacks to security that have been observed in association with the IS. This is because there are a number of access points that are present in these information systems. The access points are utilized by the attackers to give shape to the attacks that adversely implicate the properties of the information and data sets. The organization ensured that such security vulnerabilities and loopholes were avoided by closely syncing the systems and their components with each other (Chesla, 2004). The EA includes advanced security components and modules at every layer. There are mechanisms, such as access control, authentication, encryption, intrusions detection, and prevention that are used to prevent and avoid such security issues (Alshammari, 2017). Comparison between IS EA There are various differences between the information system its architecture and the enterprise architecture. Point of Difference IS its Architecture EA Scope Specific requirement sets are addressed Continuously changing and ambiguous requirements are addressed Product The system as a whole is developed as a product There are multiple modules and components developed along with numerous methods and procedures Stakeholders System Owner is the sole stakeholder There are numerous stakeholders involved Lifecycle It ends when the system is developed and is delivered The lifecycle continues in a loop and is for continuous improvement Governance Limited governance Enhanced level of governance Findings There are a number of different viewpoints and aspects that are associated with Information Systems, associated strategies, and Enterprise Architecture. In most of the research works and activities, the main focus is laid on the complete technical infrastructure and the modeling frameworks that are involved. As a result, the communication and relationship between the parties and the stakeholders is developed. The other works of research have focused on the stakeholders and their requirements. It has been stated that the stakeholder requirements shall be kept high on priority (Malta Sousa, 2016). Some of the research works and journals state that the planning and communication activities shall be considered as top priority while designing EA and IS. The decision-making activities are also taken accordingly. Components that Need Further Research There are certain areas that have not been completely explored by the researchers so far. The ethical aspect of the social relationships and engagement between the different stakeholders, architects, and resources is not covered. The researchers have mainly focused on the architectural models and structures, effective communication, effective planning and viewpoints are the main areas that are primarily covered. The ethical aspect is not covered well (Sasa Krisper, 2011). Enterprise Architecture has been depicted as an amalgamated unit of various modules that and combined together in one framework. The above sections also provide details on the specific architectural requirements and functioning information (Shah Kourdi, 2007). The specific needs of all the individual entities associated with the information systems and the EA shall also be addressed so that the specific objectives can be attained. The research articles, journals, and papers do not lay emphasis on the ethical professional codes that shall be complied with and reflected in the process. Consequences Impacts of EA Processes The research works that have been analyzed and references consider social relationship and communication between the stakeholders and the architects as a prime necessity. There are several advantages that are provided to the business organizations as a result of the development and implementation of strong social relationships. The specific requirements of the stakeholders will provide the basic necessities and patterns that shall be implemented. The stakeholder will achieve the needs as per their requirements without any ambiguities and confusion (Donaldson, Blackburn, Blessner Olson, 2015). As a result, the operational errors will be reduced and the amount of re-work that is usually required with the information systems and their configuration is also brought down. There are advantages that are provided to the enterprises as well. The performance of the enterprises is improved. Conclusion EA is a concept that allows the enterprises to strategically plan and align the information systems and applications with the business objectives. The main objective of EA is to present the guidelines that can be implemented by an enterprise so that it may achieve the business goals and objectives. Enterprise Architecture amalgamates the description of the best applications, strategies, technologies, and procedures that an organization shall implement along with the integration mechanism between these elements. Communication between the information systems installed in an organization is a significant need to achieve the benefits. Also, it is required that the internal and external stakeholders along with all of the resources engaged with an enterprise maintain enhanced communication levels with each other.
