Solid Rocket Ramjet Engine Integrated Design Research

In this paper, the theory of minitype Solid Ducted Rocket with shot is researche nd analyzed. At first, the thermodynamic calculation of Solid Ducted Rocket is researche. A computer program was developed based on the minimum free energy algorithm, The program consists of several compute modules including assumption chemical molealar formula calculation, final combust resultant calculation of combusting chamber nd combustion temperature calculation in steady pressure etc. Calculations of kind of propellants are done many times by the program. Results show that the program is goa at veracity and all-purpose.Moreover, the holistic calculation of process of Solid Ducted Rocket is researaed. After setting up physics model and maths model of minitype Solid Ducted Rocket -\ih shot, performance of engine is calculated and analyzed according to the resu; of thermodynamic calculation.At last, processes of Solid Ducted Rocket in different working condition re researched. The research shows that the working speciality accords with the trajecory speciality. The result provides the gist of increasing range bomb and rocket in strucure design and experimentation research.
