    en.wikipedia.org/wiki/Turbonique

    Turbonique was a company founded in 1962 [1] by Clarence Eugene "Gene" Middlebrooks Jr of Orlando, Florida. [2] Middlebrooks, born 3 August 1931, [3] was a native of Jonesboro, Georgia, had studied mechanical engineering at Georgia Tech and had worked for aerospace contractor Martin-Marietta on the propulsion system for the Pershing missile program.

  3. Rocket engine nozzle - Wikipedia

    en.wikipedia.org/wiki/Rocket_engine_nozzle

    Figure 1: A de Laval nozzle, showing approximate flow velocity increasing from green to red in the direction of flow Density flow in a nozzle. A rocket engine nozzle is a propelling nozzle (usually of the de Laval type) used in a rocket engine to expand and accelerate combustion products to high supersonic velocities.

  4. Air turborocket - Wikipedia

    en.wikipedia.org/wiki/Air_turborocket

    The benefit of this setup is increased specific impulse over that of a rocket. For the same carried mass of propellant as a rocket motor, the overall output of the air turborocket is much higher. In addition, it provides thrust throughout a much wider speed range than a ramjet, yet is much cheaper and easier to control than a gas turbine engine.

  5. Propelling nozzle - Wikipedia

    en.wikipedia.org/wiki/Propelling_nozzle

    The afterburners on combat aircraft require a bigger nozzle to prevent adversely affecting the operation of the engine. The variable area iris [9] nozzle consists of a series of moving, overlapping petals with a nearly circular nozzle cross-section and is convergent to control the operation of the engine. If the aircraft is to fly at supersonic ...

    en.wikipedia.org/wiki/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] 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.

  7. Pressure-fed engine - Wikipedia

    en.wikipedia.org/wiki/Pressure-fed_engine

    Pressure-fed rocket cycle. Propellant tanks are pressurized to directly supply fuel and oxidizer to the engine, eliminating the need for turbopumps. The pressure-fed engine is a class of rocket engine designs. A separate gas supply, usually helium, pressurizes the propellant tanks to force fuel and oxidizer to the combustion chamber. To ...
