  3. 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.

  4. 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 ...

    The following chart shows the number of launch systems developed in each country, and broken down by operational status. Rocket variants are not distinguished; i.e., the Atlas V series is only counted once for all its configurations 401–431, 501–551, 552, and N22.

  7. Specific impulse - Wikipedia

    en.wikipedia.org/wiki/Specific_impulse

    For any chemical rocket engine, the momentum transfer efficiency depends heavily on the effectiveness of the nozzle; the nozzle is the primary means of converting reactant energy (e.g. thermal or pressure energy) into a flow of momentum all directed the same way. Therefore, nozzle shape and effectiveness has a great impact on total momentum ...

  9. Rocket engine - Wikipedia

    en.wikipedia.org/wiki/Rocket_engine

    Rocket engine nozzles are surprisingly efficient heat engines for generating a high speed jet, as a consequence of the high combustion temperature and high compression ratio. Rocket nozzles give an excellent approximation to adiabatic expansion which is a reversible process, and hence they give efficiencies which are very close to that of the ...
