| Abstract: | A mathematical model for performance calculation of solid propellant air-turbo-rocket in design state was derived,and a relationship of fuel-air ratio in the chamber was put forward.The effects of compressor pressure ratio,turbine inlet fuel total temperature and turbine expansion ratio on the fuel-air ratio together with the design features of solid propellant air-turbo-rocket were analyzed.Based on the power balance condition of compressor and turbine,the mixing condition of eqivalent static pressure and the flow matching condition of the blast tube,a mathematical model for performance calculation of solid propellant air-turbo-rocket in off-design state was deduced. |

| Keywords: | solid propellant air-turbo-rocket(SPATR) design state off-design state mathematical model |
