  2. Comparison of orbital launch systems - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_orbital...

    All launch vehicle propulsion systems employed to date have been chemical rockets falling into one of three main categories: Solid-propellant rockets or solid-fuel rockets have a motor that uses solid propellants, typically a mix of powdered fuel and oxidizer held together by a polymer binder and molded into the shape of a hollow cylinder. The ...

  3. 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.

  4. 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 ...

    A Soyuz-FG rocket launches from "Gagarin's Start" (Site 1/5), Baikonur Cosmodrome. A rocket (from Italian: rocchetto, lit. ''bobbin/spool'', and so named for its shape) [nb 1] [1] is a vehicle that uses jet propulsion to accelerate without using any surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. [2]

    The record-shattering rocket launch was only about 3.8 miles short of the altitude allowed for amateur rocketry, but the students are hoping to break new records in the club’s future.

  8. Cryogenic rocket engine - Wikipedia

    en.wikipedia.org/wiki/Cryogenic_rocket_engine

    RL-10 is an early example of cryogenic rocket engine. Rocket engines need high mass flow rates of both oxidizer and fuel to generate useful thrust. Oxygen, the simplest and most common oxidizer, is in the gas phase at standard temperature and pressure, as is hydrogen, the simplest fuel.
