  2. Tsiolkovsky rocket equation - Wikipedia

    en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation

    A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...

  3. 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 ...

  4. Mass ratio - Wikipedia

    en.wikipedia.org/wiki/Mass_ratio

    This equation can be rewritten in the following equivalent form: = / The fraction on the left-hand side of this equation is the rocket's mass ratio by definition. This equation indicates that a Δv of n {\displaystyle n} times the exhaust velocity requires a mass ratio of e n {\displaystyle e^{n}} .

  5. Working mass - Wikipedia

    en.wikipedia.org/wiki/Working_mass

    Working mass, also referred to as reaction mass, is a mass against which a system operates in order to produce acceleration.In the case of a chemical rocket, for example, the reaction mass is the product of the burned fuel shot backwards to provide propulsion.

  6. 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 ...

  7. Orbital maneuver - Wikipedia

    en.wikipedia.org/wiki/Orbital_maneuver

    Rocket mass ratios versus final velocity calculated from the rocket equation. The Tsiolkovsky rocket equation, or ideal rocket equation, can be useful for analysis of maneuvers by vehicles using rocket propulsion. [2] A rocket applies acceleration to itself (a thrust) by expelling part of its mass at high speed. The rocket itself moves due to ...
