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]
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.
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 ...
The program ended early due to financial and technical difficulties. In 1961, he was selected as chief test pilot for the flight test program of the XB-70 Valkyrie, the world's largest supersonic aircraft, piloting the first flights of both XB-70s and taking the aircraft through the buildup programs to flight at Mach 3.

A number of aircraft were designed to make use of zip, including the XB-70 Valkyrie, XF-108 Rapier, as well as the BOMARC, and even the nuclear-powered aircraft program. The Navy considered converting all of their jet engines to zip and began studies of converting their aircraft carriers to safely store it.
Notice the inverse relationship between level of wealth and share of nonfinancial assets: On average, about 70% of the assets of the least wealthy tend to be their homes and vehicles.
The F-104 was estimated to be 70 ft (20 m) to the side of, and 10 ft (3 m) below, the fuselage of the XB-70. The report concluded that from that position, without appropriate sight cues, Walker was unable to properly perceive his motion relative to the Valkyrie, leading to his aircraft drifting into contact with the XB-70's wing.
