A fuel containing methylacetylene-propadiene, commonly referred to as MAPP gas, produces thrust in a flight vehicle having a pulse detonation engine. The MAPP gas fuel of this invention may be used alone or combined with other conventional fuels such as hydrogen, JP-4, JP-5, JP-10, kerosene or any o
A fuel containing methylacetylene-propadiene, commonly referred to as MAPP gas, produces thrust in a flight vehicle having a pulse detonation engine. The MAPP gas fuel of this invention may be used alone or combined with other conventional fuels such as hydrogen, JP-4, JP-5, JP-10, kerosene or any other suitable hydrocarbon fuel. Such hydrocarbon containing fuel includes, but is not limited to, acetylene, methane, ethylene, propane, butane or liquified petroleum gas. MAPP gas fuel is mixed with an oxidant containing oxygen or air and ignited. The detonation wave created produces thrust for the flight vehicle. A method of powering a flight vehicle having a pulse detonation engine with MAPP gas fuel is also disclosed.

1. A method of powering a flight vehicle having a pulse detonation engine, comprising: (a) supplying a MAPP gas fuel and an oxidant to a detonation chamber of a pulse detonation engine to form a detonable mixture; and (b) igniting the detonable mixture in the detonation chamber to create a propa
1. A method of powering a flight vehicle having a pulse detonation engine, comprising: (a) supplying a MAPP gas fuel and an oxidant to a detonation chamber of a pulse detonation engine to form a detonable mixture; and (b) igniting the detonable mixture in the detonation chamber to create a propagating detonation wave of detonation gases in the chamber. 2. The method of claim 1 further includes purging the detonation gases from the detonation chamber, then repeating steps (a) and (b). 3. The method of claim 1 wherein the MAPP gas fuel comprises methyacetylene-propadiene. 4. The method of claim 1 wherein the oxidant contains at least oxygen or air. 5. The method of claim 3 further comprising mixing the MAPP gas fuel with a second fuel selected from the group consisting of hydrogen, JP-4, JP-5, JP-10, kerosene, acetylene, methane, ethylene, propane, butane and liquid petroleum gas. 6. The method of claim 1 wherein step (a) includes flowing the MAPP gas fuel and the oxidant separately into the detonation chamber and mixing the MAPP gas fuel and oxidant while in the detonation chamber. 7. The method of claim 1 wherein step (a) comprises storing the MAPP gas fuel as a liquid in a tank and delivering the MAPP gas fuel as a gas to the detonation chamber. 8. A method of powering a flight vehicle having a pulse detonation engine, comprising: (a) flowing a detonable mixture of a MAPP gas fuel, a second fuel, and an oxidant to a detonation chamber of a pulse detonation engine, the second fuel being selected from the group consisting of hydrogen, JP-4, JP-5, JP-10, kerosene, acetylene, methane, ethylene, propane, butane and liquid petroleum gas, the oxidant containing at least oxygen or air; and (b) detonating the detonable mixture in the chamber to create thrust for powering the engine; and (c) removing the detonation products from the chamber, then repeating steps (a) and (b). 9. A flight vehicle having a pulse detonation engine, comprising: a tank of MAPP gas fuel; a source of oxidant; a detonation chamber in fluid communication with the tank of MAPP gas fuel and the oxidant source, the chamber structured to propagate a detonable wave of gases when a mixture of MAPP gas fuel and oxidant is ignited; an igniter in communication with the detonation chamber for igniting the detonable mixture; the MAPP gas fuel containing methyacetylene-propadiene; and a second fuel mixed with the MAPP gas fuel, the second fuel being selected from the group consisting of hydrogen, JP-4, JP-5, JP-10, kerosene, acetylene, methane, ethylene, propane, butane and liquid petroleum gas.
