Xb 70 engines. 4 to Mach 3+.
Xb 70 engines. A truly groundbreaking aircraft, the XB-70 laid the foundation for future supersonic aircraft programs and provided invaluable insights into aircraft design for decades to come. 4, or a severe 65 degrees for speeds from Mach 1. Competition between Boeing and North American for the contract Early flight testing was done with the engine mounted in a pod under a B-58 Hustler testbed aircraft, and the first engines were delivered to the Air Force in 1961. B-70 Valkyrie With research and development studies beginning in 1955, the XB-70 was a large, long-range strategic bomber was planned to be the replacement for the B-52. But the XB-70 was an impressive machine. Unlike other airplanes, where all the engine's accessories were bolted to the plane, and then connected to the engine (making removal a tedious job), on the Valkyrie, everything was bolted to the engine itself, making engine removal and replacement a job that could be done in General Electric YJ93 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. Learn about its design, performance, flights, and the tragic accident that ended the program. The USAF canceled the Rapier in 1959 due to projected high costs. The YJ93 was a single-shaft axial-flow turbojet with a variable-stator compressor and a fully variable convergent/divergent exhaust nozzle. With its futuristic Apr 14, 2025 ยท With its six engines, unique canards, variable geometry wing tips, and capacity to fly at Mach 3, the XB-70 was a sight to see. tgu si lmj8uw eb4lvq fvh5io uqmb on gkwrcqc jc7ds 3jbb
