  2. Characteristic velocity - Wikipedia

    en.wikipedia.org/wiki/Characteristic_velocity

    Characteristic velocity or , or C-star is a measure of the combustion performance of a rocket engine independent of nozzle performance, and is used to compare different propellants and propulsion systems. c* should not be confused with c, which is the effective exhaust velocity related to the specific impulse by: =. Specific impulse and ...

    After 55 seconds of flight, a command was sent to cut propulsion, and the rocket crashed 4 miles (6 km) or 5 miles (8 km) downrange. [12]: 172–181 On June 30th, 2024, during a static fire test of the first stage of the Space Pioneer Tianlong-3, a structural failure between the rocket and test stand resulted in an unintentional launch.

  5. Propulsive efficiency - Wikipedia

    en.wikipedia.org/wiki/Propulsive_efficiency

    In aerospace engineering, concerning aircraft, rocket and spacecraft design, overall propulsion system efficiency is the efficiency with which the energy contained in a vehicle's fuel is converted into kinetic energy of the vehicle, to accelerate it, or to replace losses due to aerodynamic drag or gravity.

  6. Propellant mass fraction - Wikipedia

    en.wikipedia.org/wiki/Propellant_mass_fraction

    In rockets for a given target orbit, a rocket's mass fraction is the portion of the rocket's pre-launch mass (fully fueled) that does not reach orbit.The propellant mass fraction is the ratio of just the propellant to the entire mass of the vehicle at takeoff (propellant plus dry mass).

  8. Rocketdyne AR2 - Wikipedia

    en.wikipedia.org/wiki/Rocketdyne_AR2

    The Rocketdyne division of North American Aviation developed a relatively small liquid-fuelled rocket engine for thrust augmentation of manned aircraft during the late 1950s. The AR2 is a single-chamber rocket engine burning kerosene ( JP-4 or JP-5 ) jet fuel, oxidised with 90% High Test Peroxide (H 2 O 2 / HTP), allowing the engine to use the ...

  9. Pintle injector - Wikipedia

    en.wikipedia.org/wiki/Pintle_injector

    Fuel in red, oxidizer in blue. The pintle injector is a type of propellant injector for a bipropellant rocket engine.Like any other injector, its purpose is to ensure appropriate flow rate and intermixing of the propellants as they are forcibly injected under high pressure into the combustion chamber, so that an efficient and controlled combustion process can happen.
