  2. Hybrid-propellant rocket - Wikipedia

    en.wikipedia.org/wiki/Hybrid-propellant_rocket

    Hybrid rocket propulsion system conceptual overview. In its simplest form, a hybrid rocket consists of a pressure vessel (tank) containing the liquid oxidizer, the combustion chamber containing the solid propellant, and a mechanical device separating the two. When thrust is desired, a suitable ignition source is introduced in the combustion ...

  3. Rocket propellant - Wikipedia

    en.wikipedia.org/wiki/Rocket_propellant

    Solid rockets use propellant in the solid phase, liquid fuel rockets use propellant in the liquid phase, gas fuel rockets use propellant in the gas phase, and hybrid rockets use a combination of solid and liquid or gaseous propellants. In the case of solid rocket motors, the fuel and oxidizer are combined when the motor is cast.

  5. 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 ...

  6. Nitrous oxide fuel blend - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide_fuel_blend

    The propellant used in a rocket engine plays an important role in both engine design and in design of the launch vehicle and related ground equipment to service the vehicle. Weight, energy density, cost, toxicity, risk of explosions, and other problems make it important for engineers to design rockets with appropriate propellants. The major ...

  7. Liquid-propellant rocket - Wikipedia

    en.wikipedia.org/wiki/Liquid-propellant_rocket

    Liquid rockets can be monopropellant rockets using a single type of propellant, or bipropellant rockets using two types of propellant. Tripropellant rockets using three types of propellant are rare. Liquid oxidizer propellants are also used in hybrid rockets, with some of the advantages of a solid rocket.

  8. Liquid rocket booster - Wikipedia

    en.wikipedia.org/wiki/Liquid_rocket_booster

    A liquid rocket booster (LRB) uses liquid fuel and oxidizer to give a liquid-propellant or hybrid rocket an extra boost at take-off, and/or increase the total payload that can be carried. It is attached to the side of a rocket.

  9. Hybrid rocket fuel regression - Wikipedia

    en.wikipedia.org/wiki/Hybrid_Rocket_Fuel_Regression

    Hybrid rocket fuel regression refers to the process by which the fuel grain of a hybrid-propellant rocket is converted from a solid to a gas that is combusted. It encompasses the regression rate, the distance that the fuel surface recedes over a given time, as well as the burn area, the surface area that is being eroded at a given moment.
