Bell Aerosystems began development of a rocket pack which it called the "Bell Rocket Belt" or "man-rocket" for the US Army in the mid 1950s. [1] It was demonstrated in 1961 but 5 gallons of hydrogen peroxide fuel needed for 21 seconds of flight time did not impress the army.
The bell-shaped or contour nozzle is probably the most commonly used shaped rocket engine nozzle. It has a high angle expansion section (20 to 50 degrees) right behind the nozzle throat; this is followed by a gradual reversal of nozzle contour slope so that at the nozzle exit the divergence angle is small, usually less than a 10 degree half angle.
1961 Bell Rocket Belt, personal VTVL rocket belt demonstrated. [3] VTVL rocket concepts were studied by Philip Bono of Douglas Aircraft Co. in the 1960s. [4] Apollo Lunar Module was a 1960s two-stage VTVL vehicle for landing and taking off from the Moon. Australia's Defence Science and Technology Group successfully launched the Hoveroc rocket ...
Thus, the Bell Jet Flying Belt remained an experimental model. On 29 May 1969, Wendell Moore died of complications from a heart attack he had suffered six months earlier, and work on the turbojet pack ended. Bell sold the sole version of the "Bell pack", together with the patents and technical documentation, to Williams Research Corporation.
The Bell X-1 (Bell Model 44) is a rocket engine–powered aircraft, designated originally as the XS-1, and was a joint National Advisory Committee for Aeronautics–U.S. Army Air Forces–U.S. Air Force supersonic research project built by Bell Aircraft. Conceived during 1944 and designed and built in 1945, it achieved a speed of nearly 1,000 ...
In March 2017 ARCA Space Corporation announced their intention to build a single-stage-to-orbit (SSTO) rocket, named Haas 2CA, using a linear aerospike engine. The rocket is designed to send up to 100 kg into low-Earth orbit, at a price of US$1 million per launch. [9]
The Bell X-2 (nicknamed "Starbuster" [1]) was an X-plane research aircraft built to investigate flight characteristics in the Mach 2–3 range. The X-2 was a rocket-powered, swept-wing research aircraft developed jointly in 1945 by Bell Aircraft Corporation, the United States Army Air Forces and the National Advisory Committee for Aeronautics (NACA) to explore aerodynamic problems of ...
Simple bell-shaped nozzles were developed in the 1500s. The de Laval nozzle was originally developed in the 19th century by Gustaf de Laval for use in steam turbines. It was first used in an early rocket engine developed by Robert Goddard, one of the fathers of modern rocketry.
