It was the XB-70 XB-70 NASA Photo ECN-1814. Because the XB-70 is the first large supersonic-cruise vehicle with performance, flexibility, and inertial characteristics representative of future designs, a landing loads study was made on the airplane. 1. The purpose of this program was to measure landing-contact conditions as well as representative gear loads due to landing impact and the resulting accelerations imparted to the airframe, and Apr 16, 2022 · Much of the XB-70's NASA testing was to study the possibility of an American-made supersonic transport (SST) to compete with the Anglo-French Concorde and Soviet Tu-144. The first NASA flight took place on April 25, 1967, with Air Force Colonel Joseph Cotton at the controls and NASA’s Fitzhugh Fulton as co-pilot. Forward of these, on the cockpit floor, are the rudder pedals with the NAA (North American Aviation) trademark. During NASA flights, the XB-70 flew at differing Mach numbers, altitudes and weights over an instrumented test range at Edwards as part of the National Sonic Boom Program. They flew a total of 129 flights between 1964-1969. . On the left and right sides of the picture are the pilot's and co-pilot's control yokes. The first NASA XB-70 flight occurred on April 25, 1967, by Fulton and Cotton. The XB-70-1 airplane was manufactured with the wings mounted at a geometric dihedral angle of zero. Illustrations from a 1967 report showing the significant role of the XB-70A in the SST program. In-flight response characteristics at a number of points on The XB-70 suffered buffeting during high-speed, high-altitude flights and to rectify this, a turbulence reduction system was fitted in March 1968. The XB-70 flight experience indicated that the height of the cockpit above the runway in combination with nose-high landing attitudes and high approach speeds made the landing task more difficult than that for current subsonic jet transports. All inlet simula- tions and flight data in this report are for the XB-70-1 inlet system operating in the manual mode, unless otherwise noted. The joint program among North American Rockwell, the Air Force, and NASA featured the world's largest experimental aircraft with a delta wing and hinged wing tips that could be folded down to a 65° angle to improve stability.

Sep 28, 2009 · The XB-70A, capable of flying three times the speed of sound, was the world’s largest experimental aircraft in the 1960s. Although not doing as well as AV/2 would have, the older Valkyrie soldiered on for 33 additional flights, garnering valuable data about high-speed flight. Ultimately, after a few more flights, the Air Force bowed out of the XB-70 program, leaving NASA to carry on additional flights on its own. XB-70 AV/1 flew 12 times over the following year at different speeds, altitudes, and payload weights. Two XB-70A aircraft were built, serial numbers 62-0001 and 62-0207. Go to the Space ! This aircraft was shaped to fly at MACH 3 remaining within its Mach cone throughout the flight regime, using the shock waves beneath the wing to generate compression lift. The North American Aviation XB-70 Valkyrie is a retired prototype version of the planned B-70 nuclear -armed, deep-penetration supersonic strategic bomber for the United States Air Force Strategic Air Command. 1967 NASA Photo The North American Aviation XB-70 triple-sonic bomber prototype aircraft No. Jan 5, 2014 · The B-70 Valkyrie, with a planned cruise speed of Mach 3 and operating altitude of 70,000 feet, was to be the ultimate high-altitude, high-speed manned strategic bomber. Three-degree glide slopes were considered unsatisfactory at the 200-knot indicated airspeed approaches required by the XB-70. The high rate of descent Feb 8, 2016 · North American manufactured two airframes. 6 at an altitude of 40,000 feet (one case). In 1971, the American SST program was canceled, in part due to the problem of sonic booms on the ground—sonic booms are loud, explosive noises caused by aircraft flying faster than the speed of sound. Program management of the NASA-USAF research effort was assigned to NASA in March 1967. North American XB-70 Valkyrie history, specifications, schematics, pictures, and data. Ship #1 was flown by NASA Flight Research Center now NASA Dryden, Edwards, Calif. NASA used the pre-production bomber for high-speed research in the mid-1960s. Sep 28, 2009 · ED97-44244-1The XB-70 #1 cockpit, which shows the complexity of this mid-1960s research aircraft. The resulting shape used a delta wing that powered the aircraft. 90 at an altitude of 25,000 feet (two cases), a nominal Mach number of 1. THE XB-70 VALKYRIE STORY In the 1960's a 10-man crew of electronic engineers and technicians operated the NASA High Range Tracking Station at Beatty, Nevada. Ship #1 was flown by NASA Flight Research Center, Edwards, CA, in a high-speed research program. The NASA XB-70 program continued to receive Air Force assistance, in terms of aircraft support and Air Force test pilots. The USAF transferred XB-70A AV-1 to NASA in 1967 in support of the National Supersonic Transport Program. Early analysis of XB-70 flight data obtained in mode rate-to-rough turbulence (ref. Aug 19, 2013 · Review of the XB-70 Flight Program Although the major NASA research effort is directed toward XB-70-2, which will not enter its flight program until the summer of 1965, a limited amount of information is available from the early flights of the XB-70-1 airplane. 1) at supersonic speeds indicated marked structural motion at the pilot' s station in the first four symmetric structural modes. Originally designed as a Mach 3 bomber, the XB-70A never went into production and instead was used for flight research involving the Air Force and NASA’s Flight Research Center, which was a predecessor of today’s NASA Dryden Flight Research Center. Positions for the navigator and bombardier were removed, leaving the XB-70 with just a pilot and co-pilot. 2 and 3) based on early XB-70 design Sep 28, 2009 · The XB-70A is shown parked on a ramp at Edwards Air Force Base in 1967. The XB-70 airplane is typical of the new generation of large, highly flexible air-craft. 1968NASA Photo › XB-70 Project Description When the XB-70 was flying at or near Mach 3, the slower TB-58 could often keep up with it by flying lower and cutting inside the turns in the XB-70’s flight path when these occurred. NASA and the Air Force would jointly manage and share the data garnered from the XB-70. Initially, their primary mission was the tracking of X-15 missions originating at Dryden/Edwards AFB in California. Although previous analytical studies (refs. However, before the initial flight testing, simulator studies indicated that at high Mach number with the stability augmentation off and the wing tips deflected to 65" the airplane was sensitive to the roll and yaw mode with aileron deflec- tion and that approximately 5" of positive geometric Apr 21, 2015 · At the conclusion of Phase II, NASA took over the XB-70 program.
