- For example, a mixture ratio of a bipropellant could be adjusted such that it may not have the optimal specific impulse, but will result in fuel tanks of equal size.
- Larger satellites usually use monopropellants or bipropellant combustion systems for propulsion and attitude control; these systems are complex and require a minimal amount of volume to surface area to dissipate heat.
- The bipropellant system had a total capability of about 1, 900 m / s with about 550 m / s required for lunar insertion and 540 m / s for lunar departure.
- While noticeably less than the " I " sp available from hydrazine thrusters ( monopropellant or bipropellant with dinitrogen tetroxide ), the decreased toxicity makes nitrous oxide an option worth investigating.
- Apogee kick motors often employ either a bipropellant engine, with a solid fuel and a liquid oxidiser, or a monopropellant engine with both the fuel and the oxidiser in a solid state.
- In 1981, the Naval Weapons Center tried a 350 round / minute cyclic bipropellant gun, using 90 % nitric acid and a proprietary hydrocarbon ( probably a low molecular weight alkane, like propane ).
- Its main engine, which is a derivative of the system used on India's communications satellites, uses the bipropellant combination monomethylhydrazine and dinitrogen tetroxide to achieve the thrust necessary for escape velocity from Earth.
- Performance of electrothermal systems in terms of specific impulse ( Isp ) is somewhat modest ( 500 to ~ 1000 seconds ), but exceeds that of cold gas thrusters, monopropellant rockets, and even most bipropellant rockets.
- The "'Walter HWK 109-509 "'was a bipropellant rocket engine that powered the Messerschmitt Me 163 Komet and Bachem Ba 349 aircraft . It was produced by Hellmuth Walter Kommanditgesellschaft ( HWK ) commencing in 1943.
- The installed Pintle Injector, unique to TRW designed liquid propulsion systems, provides improved reliability and less costly method of fuel-oxidizer impingement in the thrust chamber than conventional coaxial distributed-element injectors typically used on liquid bipropellant rocket engines.
- The laboratory created the "'Space Systems Initiative "'which would allow the space center to provide bipropellant rockets and liquid methane / liquid oxygen control engines with the university to enabling students to gain a better understanding of rocket performance.
- Meanwhile, Walter had started work on the newer HWK 109-509 bipropellant " hot engine ", which added a true fuel of Reichsluftfahrtministerium " ( RLM ) requirement that it should be possible to throttle the engine, the original power plant grew complicated and lost reliability.
- During World War II, high-test peroxide was used as an oxidizer in some German bipropellant rocket designs, such as the Walter HWK 509A rocket engine that powered the Messerschmitt Me 163 point defense interceptor fighter late in World War II, comprising 80 % of the standardized mixture " T-Stoff ", and also in the German Type XVII submarine.
- Another of T-Stoff's many uses was to be combined as the oxidizer, with C-Stoff ( methanol-hydrazine-water mixture ) as the fuel, in the bipropellant Walter HWK 109-509 engine of the Messerschmitt Me 163 and Messerschmitt Me 263, at a ratio of approximately 3.1 parts T-Stoff oxidizer to one part C-Stoff fuel.
- "' Ventions "', LLC is a launch vehicle development company based out of San Francisco, California, that has been working to develop pump-fed, liquid bipropellant propulsion engines for DARPA and NASA . Most recently, Ventions was a technology provider for DARPA's Airborne Launch Assist Space Access ( ALASA ) program, and is currently working on the Small Air Launch Vehicle to Orbit ( SALVO ) program, a pathfinder air-launched vehicle for placement of cubesat sized payloads into Low Earth Orbit.
