Abstract:
This paper introduced a gas turbine performance test bench of a liquid rocket engiue． The mass fluxes of air，fuel，water and outlet pressure of the gas turbine were chosen to be the main controlling elements in the system．The dynamical model of every part was established．The effective elements on inlet pressure，inlet temperature and rotating speed of the gas turbine are aIla． 1yzed by using linear small deviation equations．The regulating rule of manual control Was confirmed． The inlet pressure of the gas turbine depended on the air flux．The inlet temperature related with both air flux and fuel flux．The rotating speed Was controlled by the water flux．
