The history of Convair NX-2 Camal, a secret project to develop an atomic-powered bomber. Convair's NX-2 (designated Model 54 in-house) proposed powering the subsonic, ultra-long endurance jet bomber (about the size of a B-52) with either Pratt & Whitney indirect air cycle nuclear engines or General Electric direct air cycle nuclear engines. The U.S. Nuclear Propulsion Program (or Manned Nuclear Aircraft Program) began in May 1946. This after Fairchild Engine and Aircraft Corporation, received the first formal study contract. The objective, is to determine the feasibility of nuclear energy for the propulsion of aircraft. The Fairchild project known as the Nuclear Energy for Propulsion of Aircraft (NEPA) began at the Oak Ridge National Laboratory, TN. Work at Oak Ridge proved building a nuclear aircraft was feasible and defined the major approaches to the program. As a result, the Air Force and Atomic Energy Commission (AEC) joined forces in the Aircraft Nuclear Propulsion (ANP) Program. In 1951, they contracted with the General Electric (GE) Company at Evendale, Ohio to, “…develop a nuclear aircraft propulsion system through an exacting research, development, design and component-test program on reactors, materials, shielding and an over-all nuclear power plant.” 1 At the time, there appeared to be two design concepts for a “nuclear” aircraft: the Direct-Air-Cycle and the Indirect. General Electric elected the Direct-Air-Cycle2 due to the perceived simplicity, flexibility, adaptability, and ease of handling. General Electric quickly developed high-temperature, compact, lightweight reactors and shields required for aircraft flight. The GE Company also believed their new technology had applicability to aerospace and ground power systems. In the 1950s, nuclear reactors were approximately the size of two railroad cabooses stacked on one another, and the performance requirements for aircraft nuclear power plants were much more schematic. The objective of the ANP Program expanded to include the demonstration of nuclear-powered flight. Still, in 1952, the Air Force decided that direct nuclear cycle engine developments were progressing well and began construction of a power plant for the Convair B-36 flight testing and targeted 1956 for the first flight. In 1953 the Secretary of Defense Charles E. Wilson abruptly canceled the B-36 experimental flight program, Wilson, a skeptic, contended “that experimental “proof-of-principle” flights were worthless unless they were performed by a prototype for as an actual weapon systems.”4 The money slated for the project was for a weapons system so, the prototype requirements leaned in this direction. Though the B-36 experiment halted, Air Force leaders managed to keep GE’s direct cycle developments moving forward and Pratt and Whitney continued their progress. Pratt and Whitney used a pressurized water, indirect cycle engine which failed to progress (see below schematic). Pratt and Whitney changed gears and began working with Oak Ridge on a molten salt circulation fuel reactor, still using the indirect cycle nuclear turbojet concept. Pratt and Whitney remained behind GE in developments throughout the testing and experimentation. Though Air Force leaders canceled developments for a B-36 nuclear-powered aircraft, a Convair B-36, designated as the NB5-36H and specially refitted to contain a fully operational nuclear reactor however, the NB-36H did not use the reactor for propulsion. In 1958, the Air Force introduced a new mission requirement in an attempt to keep the ANP Program alive. Known as CAMAL (continuous airborne alert, missile launching, and low-level penetration), it was a rehashing of a nuclear weapons system aircraft.8 During the summer of 1959, Dr. Herbert F. York, Director of Defense Research and Engineering in the Pentagon, and other Department of Defense research officials pushed a reorientation of the ANP Program project. These officials called for the development of a useful nuclear turbojet capable of installation in and flown on a Convair Model 54 (the NX-2) Watch more aircraft, heroes, and their stories, and missions ➤ / @dronescapes To support/join the channel ➤ / @dronescapes IG ➤ / dronescapesvideos FB ➤ / dronescapesvideos X/Twitter ➤ https://dronescapes.video/2p89vedj THREADS ➤ https://www.threads.net/@dronescapesv... #Convair #aircraft #airplane
