"MAPP gas also ignites much faster when mixed with air as compared to conventional fuels such as hydrogen or propane."
"There is a need for a PDE fuel which may create an initial detonation wave with air alone."
"Referring now to FIG. 1, the thrust generated as a function of wave frequency is shown for PDE fuels. At all wave frequencies tested, MAPP gas fuel was shown to generate greater thrust than either hydrogen or propane using air as the oxidizer."
"The MAPP gas fuel may be used alone as a fuel for a pulse detonation engine or it may be combined with other conventional fuels such as hydrogen, JP-4, JP-5, JP-10, kerosene or a hydrocarbon containing fuel. Such hydrocarbon containing fuel includes, but is not limited to, acetylene, methane, ethylene, propane, butane or liquified petroleum gas."
