The XB-70 was designed to use supersonic technologies developed for the Mach 3 SM-64 Navaho, as well as a modified form of the Navaho's inertial guidance system. [76] The XB-70 used compression lift, which resulted from a shock wave generated by the leading edge of the engine intake splitter below the apex of the wing. [77]
It was the XB-70 Valkyrie, an experimental plane developed for the US Air Force. Its inaugural flight — 60 years ago in September 1964 — kicked off a golden era for supersonic aircraft. The ...
North American Aviation (NAA) was a major American aerospace manufacturer that designed and built several notable aircraft and spacecraft. Its products included the T-6 Texan trainer, the P-51 Mustang fighter, the B-25 Mitchell bomber, the F-86 Sabre jet fighter, the X-15 rocket plane, the XB-70 bomber, the B-1 Lancer, the Apollo command and service module, the second stage of the Saturn V ...
NASA participated heavily in the design and testing of the XB-70 Valkyrie in the mid to late 1960s. NASA and the United States Air Force had a joint agreement to use the second XB–70A prototype for high–speed research flights in support of the proposed SST program. These plans went awry on June 8, 1966, when the second XB–70 crashed ...
Among them is the Apollo 15 Command Module Endeavour which orbited the Moon 74 times in 1971, one of four surviving Convair B-36 Peacemakers, the only surviving North American XB-70 Valkyrie and Bockscar—the Boeing B-29 Superfortress that dropped the Fat Man atomic bomb on Nagasaki during the last days of World War II.
The aircraft was powered by two General Electric J93 turbojet engines, also used in North American's XB-70 Valkyrie bomber, in the fuselage. [17] The F-108 was intended to carry the Hughes AN/ASG-18 radar, the U.S.'s first pulse-Doppler radar set. [18] It was to have look-down/shoot-down capability, but could track only one target at a time.
The General Electric YJ93 turbojet engine was designed as the powerplant for both the North American XB-70 Valkyrie bomber and the North American XF-108 Rapier interceptor. The YJ93 was a single-shaft axial-flow turbojet with a variable-stator compressor and a fully variable convergent/divergent exhaust nozzle.
Convair B-58A Hustler XB-70 Valkyrie Tupolev Tu-22M3 B-1B Lancer Tupolev Tu-160. A strategic bomber must carry a large bomb load over long distances. Consequently, it is a large aircraft typically with an empty weight exceeding 25,000 kg. Some have also been designed for related roles such as strategic reconnaissance and anti-shipping strike.
