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.
23.
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.
24.
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.
25.
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.
26.
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 ).
27.
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.
28.
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.
29.
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.
30.
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.
