  2. Spacecraft propulsion - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_propulsion

    For rocket-like propulsion systems, this is a function of mass fraction and exhaust velocity; mass fraction for rocket-like systems is usually limited by propulsion system weight and tankage weight. [ citation needed ] For a system to achieve this limit, the payload may need to be a negligible percentage of the vehicle, and so the practical ...

  3. Rocket propellant - Wikipedia

    en.wikipedia.org/wiki/Rocket_propellant

    The rocket is launched using liquid hydrogen and liquid oxygen cryogenic propellants. Rocket propellant is used as reaction mass ejected from a rocket engine to produce thrust. The energy required can either come from the propellants themselves, as with a chemical rocket, or from an external source, as with ion engines.

  4. Spacecraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_flight_dynamics

    A space vehicle's flight is determined by application of Newton's second law of motion: =, where F is the vector sum of all forces exerted on the vehicle, m is its current mass, and a is the acceleration vector, the instantaneous rate of change of velocity (v), which in turn is the instantaneous rate of change of displacement.

  5. Wege zur Raumschiffahrt - Wikipedia

    en.wikipedia.org/wiki/Wege_zur_Raumschiffahrt

    Wege zur Raumschiffahrt (Ways to space travel) is a book by Hermann Oberth.Written in German, it was published in 1929 by the Munich Oldenbourg publishing house [1] and was considered a standard work in rocketry for a long time.

  6. 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 ...
