Mach 3.2 in a standard day atmosphere was the design point for the aircraft. However, in practice the SR-71 was more efficient at even faster speeds and colder temperatures. The specific range charts showed for a standard day temperature, and a particular weight, that Mach 3.0 cruise used 38,000 lb per hour of fuel.
Mach 3 or variation may refer to: Supersonic speed, three times the speed of sound; M.A.C.H. 3, a 1983 LaserDisc arcade video game; Mach 3 (1987 video game)
The Mach number is named after the physicist and philosopher Ernst Mach, [3] in honour of his achievements, according to a proposal by the aeronautical engineer Jakob Ackeret in 1929. [4] The word Mach is always capitalized since it derives from a proper name, and since the Mach number is a dimensionless quantity rather than a unit of measure ...
Gillette announced the Mach3 razor on April 14, 1998, [9] following more than $750 million in R&D. [10]Gillette budgeted $300 million for a two-year advertising campaign for the Mach3 razor.
The Republic XF-103 was an American project to develop a powerful missile-armed interceptor aircraft capable of destroying Soviet bombers while flying at speeds as high as Mach 3. Despite a prolonged development, it never progressed past the mockup stage.
Most modern firearm bullets are supersonic, with rifle projectiles often travelling at speeds approaching and in some cases [6] well exceeding Mach 3. Most spacecraft are supersonic at least during portions of their reentry, though the effects on the spacecraft are reduced by low air densities. During ascent, launch vehicles generally avoid ...
The Lockheed YF-12 is an American Mach 3+ capable, high-altitude interceptor prototype, developed and manufactured by American aerospace company Lockheed Corporation.. The interceptor was developed during the late 1950s and early 1960s as a potential replacement for the F-106 Delta Dart interceptor for the United States Air Force (USAF).
Mach 3 is a 1987 3D shoot 'em up video game by Loriciels for Amiga, Amstrad CPC, Atari ST, MSX, Thomson TO7, ZX Spectrum and DOS. The DOS (PC) version uses CGA 320x200 video mode. Gameplay
