Boeing XB-56
The Boeing XB-56 was a proposal by Boeing for a re-engined version of the American jet-powered medium bomber aircraft, the B-47 Stratojet. The original designation for this modification was YB-47C. Design and development The B-47 was equipped with six General Electric J47 turbojets, each rated at thrust. The engines were mounted in four nacelles slung from the high wing, with two engines in the inboard pod and one engine in the outboard nacelle. To reduce complexity and increase commonality, it was proposed that a higher-rated engine be selected such that one engine could be mounted in each nacelle. The Allison J35 turbojet engine was being developed during the late 1940s, and it was provisionally rated at or with afterburner. Thus 4 × 8500 lbf = using that engine, as compared to 6 × 5,200 lbf = in the production B-47. Thus the conversion would be lighter, simpler and more powerful.Jones, Lloyd S.: ''U.S. Bombers: B1-B70'', Aero Publishers, Inc., 1969. ...

Boeing XB-55
Boeing XB-55 (company designation Model 474) was a proposed Boeing aircraft designed to be a strategic bomber. The XB-55 was intended to be a replacement for the Boeing B-47 Stratojet in United States Air Force (USAF) service. Design and development The XB-55 concept was contained in a Request for Proposal (RFP) issued by the United States Air Force in October 1947, two months before the first flight of the XB-47 prototype. Several United States manufacturers responded to the RFP. Boeing was selected from among this group and given a contract on 1 July 1948 to conduct further engineering studies. Boeing's initial approach was to mount four turboprop engines on an airframe similar to its B-47: the wing would have less sweepback; the Allison T40-A-2 engines would drive three-blade contra-rotating propellers, ''i.e.'', six blades per engine; the engines were to be mounted in nacelles hung from the wings, two per side; the landing gear was to be similar to the B-47's tandem gear wit ...

Naval Air Facility El Centro
Naval Air Facility El Centro or NAF El Centro is a United States Navy Naval Air Facility located approximately six miles (10 km) northwest of El Centro, in Imperial County, California. NAF El Centro is under the jurisdiction of Navy Region Southwest and serves both as temporary homeport to military units conducting air-to-air and bombing training, and as the winter training home of the Blue Angels aerobatics display team. Founded in 1946 as Naval Air Station El Centro, the facility had previously been the site of a World War II era Marine Corps Air Station. In 1979, the facility was given its current designation as a Naval Air Facility. History In 1941 the Civil Aeronautics Administration offered to replace the small airport in Imperial, California with a larger complex consisting of two 4,500ft runways. After the outbreak of World War II, the U.S. Navy leased the new airport and an adjacent 749 acres for additional construction. During this time the runways were extend ...

Pratt & Whitney J57
The Pratt & Whitney J57 (company designation: JT3C) is an axial-flow turbojet engine developed by Pratt & Whitney in the early 1950s. The J57 (first run January 1950) was the first 10,000 lbf (45 kN) thrust class engine in the United States. The J57/JT3C was developed into the J52 turbojet, the J75/JT4A turbojet, the JT3D/TF33 turbofan, and the XT57 turboprop (of which only one was built). The J57 and JT3C saw extensive use on fighter jets, jetliners, and bombers for many decades. Design and development The J57 was a development of the Pratt & Whitney XT45 (PT4) turboprop engine that was originally intended for the Boeing XB-52. As the B-52 power requirements grew, the design evolved into a turbojet, the JT3. Pratt & Whitney designed the J57 to have a relatively high overall pressure ratio to help improve both Thrust-specific fuel consumption and specific thrust, but it was known that throttling a single high pressure ratio compressor would cause stability pro ...

Boeing B-47 Stratojet
The Boeing B-47 Stratojet (Boeing company designation Model 450) is a retired American long- range, six-engined, turbojet-powered strategic bomber designed to fly at high subsonic speed and at high altitude to avoid enemy interceptor aircraft. The primary mission of the B-47 was as a nuclear bomber capable of striking targets within the Soviet Union. Development of the B-47 can be traced back to a requirement expressed by the United States Army Air Forces (USAAF) in 1943 for a reconnaissance bomber that harnessed newly developed jet propulsion. Another key innovation adopted during the development process was the swept wing, drawing upon captured German research. With its engines carried in nacelles underneath the wing, the B-47 represented a major innovation in post-World War II combat jet design, and contributed to the development of modern jet airliners. Suitably impressed, in April 1946, the USAAF ordered two prototypes, designated "XB-47"; on 17 December 1947, the fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
