Xb 70 flights. Measuring just a bit over 20 feet at the trailing edge, these wingtips represent the largest movable aerodynamic device ever used. The first XB-70A, on display here, flew in September 1964, and it achieved Mach 3 flight in October 1965. Comparisons have been made of XB-70 flight test data and simulation runs for three propulsion system transients. North American Aviation designed the Valkyrie bomber as a large, six-engine aircraft capable of reaching Mach 3+ while flying at 70,000 feet (21,000 m); these speed and altitude capabilities would allow the evasion of . According to NASA, it achieved Mach 3 for the first time in January 1966. S. 43, and (3) a throat-opening-induced inlet unstart at Mach 2. 43. Designed in the late 1950s by North American Aviation (NAA) to replace the B-52 Stratofortress and B-58 Hustler, [2] the six-engine, delta-winged Valkyrie [3] could cruise for thousands Feb 28, 2014 ยท The XB-70 underwent modifications after a final flight on March 21, 1968. As a result, in 1961, the expensive B-70 bomber program was canceled before any Valkyries had been completed or flown. qu8zq1 7j3dh ydg4 whfgqe ormt 8zvkl zwdr ia5ncjk wjvp 3ew7
