  2. 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.

  3. 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 ...

  4. Nitrous oxide fuel blend - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide_fuel_blend

    Nitrous oxide fuel blend propellants are a class of liquid rocket propellants that were intended in the early 2010s to be able to replace hydrazine as the standard storable rocket propellent in some applications. In nitrous-oxide fuel blends, the fuel and oxidizer are blended and stored; this is sometimes referred to as a mixed monopropellant.

  5. RocketMotorTwo - Wikipedia

    en.wikipedia.org/wiki/RocketMotorTwo

    RocketMotorTwo is a hybrid rocket engine utilizing solid hydroxyl-terminated polybutadiene (HTPB) fuel and liquid nitrous oxide oxidizer – sometimes referred to as an N 2 O/HTPB motor [8] [9] – providing 70,000 pounds-force (310 kN) of thrust. [10] The design makes use of lessons learned during the development of the SpaceShipOne hybrid ...

  6. TM65 - Wikipedia

    en.wikipedia.org/wiki/TM65

    The development and testing of TM65 was restarted in 2012 to explore if it was a viable replacement for the hybrid engine that Copenhagen Suborbitals previously had favored. Construction of the first prototype TM65 engine was completed in the spring of 2012 and successfully test fired in May 2012. [ 6 ]

  7. Pintle injector - Wikipedia

    en.wikipedia.org/wiki/Pintle_injector

    Fuel in red, oxidizer in blue. The pintle injector is a type of propellant injector for a bipropellant rocket engine.Like any other injector, its purpose is to ensure appropriate flow rate and intermixing of the propellants as they are forcibly injected under high pressure into the combustion chamber, so that an efficient and controlled combustion process can happen.

  8. Liquid rocket propellant - Wikipedia

    en.wikipedia.org/wiki/Liquid_rocket_propellant

    (Pressure stabilized tanks support most of the loads with internal pressure rather than with solid structures, employing primarily the tensile strength of the tank material. [ citation needed ] ) The Soviet rocket programme, in part due to a lack of technical capability, did not use liquid hydrogen as a propellant until the Energia core stage ...

  9. Delft Aerospace Rocket Engineering - Wikipedia

    en.wikipedia.org/wiki/Delft_Aerospace_Rocket...

    The number of members has increased to over 190 in 2020. Over the years DARE has developed expertise in all three major rocket propulsion technologies (solid, liquid, and hybrid), with multiple conference papers published each year. 2009 marked DARE's Stratos I launch, which set the European altitude record of 12.5 km for student rockets.
