Apollo Launch Escape System diagram. If the rocket failed in the last five minutes before launch, the CM and the launch escape system (LES, see figure) would separate from the remainder of the rocket below with the LES propelling itself and the CM beneath it upward and eastward to the sea using a small solid-fueled motor (the launch escape motor) at the top of the tower on the launch escape ...
Gemini Orbit Attitude and Maneuvering System, and Reentry (mislabeled "Reaction” [4]) Control System. The Mercury space capsule and Gemini reentry module both used groupings of nozzles to provide attitude control. The thrusters were located off their center of mass, thus providing a torque to rotate the capsule. The Gemini capsule was also ...
[13] [14] Due to the engine's potential advantage in specific impulse, if this F-1B configuration (using four F-1Bs in total) were integrated with the SLS Block 2, the vehicle could deliver 150 tonnes (330,000 lb) to low Earth orbit, [15] while 130 tonnes (290,000 lb) is what is regarded as achievable with the planned solid boosters combined ...
In 2020, Amur is planned to be a 4.1 m (13 ft)-diameter two-stage-to-orbit, medium-lift [8] vehicle of 55 m (180 ft) height, with a gross liftoff mass of 360 t (790,000 lb). [ 14 ] [ 13 ] It is aimed to deliver a payload to low Earth orbit of 10.5 t (23,000 lb), [ 8 ] but could loft 12.5 t (28,000 lb) if the first stage is expended and not ...
Unlike the float-type carburetor fuel system that relies on venturi suction to draw fuel into the engine, a pressure carburetor only uses the venturi to measure the mass airflow into the engine and manages the flow of fuel that is continuously under pressure from the fuel pump to the spray nozzle.
The rocket is designed to send up to 100 kg into low-Earth orbit, at a price of US$1 million per launch. [9] They later announced that their Executor Aerospike engine would produce 50,500 pounds-force (225 kN) of thrust at sea level and 73,800 pounds-force (328 kN) of thrust in a vacuum.

While research into this nozzle continues, it could be used before all its advantages are developed. As an upper stage, where it would be used in a low ambient pressure/vacuum environment specifically in closed wake mode, an E-D nozzle would offer weight reductions, length reductions and a potential increase to the specific impulse over bell nozzles (depending on engine cycle) allowing ...
