A New Heat Loss Correcting Way of Closed Burner Method for Measuring Solid Propellant in High Pressure

摘要

Acquiring actual gas temperature T_g of burning sample in closed burner while the heat loss exists is a key technology need to be solved. In this paper, the authors analyze the T_g obtained through heat transfer calculation or other ways by domestic and overseas researchers, and point out their disadvantages, then put forward a new high-precision way to acquire T_g. Finally, burning rate of a special composite propellant is given.
