Abstract: Two calculation methods on equivelence ratio of multi-propel-lant for propulsion system are presented in this paper. One is"mixed gas method", and another is "equivelence fuel air ratio method". There is no limit to the number of fuel and oxidant species used simultaneously. A compound engine which consists of rocket ramjet, turbo-jet and after-burner is taken as an example. The fuels used are liquid hydrogen, methane, propane and kerosene. The oxidants used are liquid oxygen and air.
