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 ...
Astrogeologist Gene Shoemaker wearing a Bell Rocket Belt while training astronauts In 1960, the Bell Rocketbelt was presented to the public. The jet of gas was provided by a hydrogen peroxide –powered rocket, but the jet could also be powered by a turbojet engine, a ducted fan, or other kinds of rockets powered by solid fuel, liquid fuel or ...
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.
Wendell Moore developed the Bell rocket belt, utilizing peroxide monopropellant rocket engines. While the rocket belt failed to be commercially developed, the rocket technology proved invaluable in future Bell programs. Bell's crowning achievement in the realm of rocketry was the Agena rocket engine. The Agena was a 12,000 lbf bi-propellant ...
Bell Model 8096B: Proposed version for use with an Agena based reusable upper stage for the Space Shuttle. It would switch propellant to MMH plus hexamethyldisilazone (HMZ) and N 2 O 4 on a 1.78 mixture ratio and add a niobium nozzle with a 100:1 expansion ratio for an increase in I sp to 327 s (3.21 km/s), or 330 s (3.2 km/s) with a 150:1 nozzle.
Comparison between the design of a bell-nozzle rocket (left) and an aerospike rocket (right) Instead of firing the exhaust out of a small hole in the middle of a bell, an aerospike engine avoids this random distribution by firing along the outside edge of a wedge-shaped protrusion, the "spike", which serves the same function as a traditional ...
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 ...
