Abstract

The flow negative regulation characteristics due to the delay between the pressure variation of gas generator and the area variation of fuel valve for the solid propellant variable flow ducted rocket(SPVFDR)was analyzed in this paper. The influence of the gas generator cavity volume and the gas valve rate on the negative regulation in a SPVFDR was investigated using numerical simulation based on the gas generator dynamic model. The results show that: the negative regulations are 82.6% and 1.7% and the response time is 0.21 s and 1.76 s when the gas generator cavity length is 0.1 m and the regulation time is 0 s and 2 s. The negative regulation are 82.6% and 11.4% and the response time is 1.69 s and 2.85 s when the gas generator cavity length is 0.8 m and the regulation time is 0 s and 2 s. Based on the results, this paper brings forward the methods to reduce SPVFDR flow negative regulation.
