Abstract
In this paper, azidoamine DMAZ is used as a fuel aid, and an oxygen bomb calorimeter is used to simulate the high-altitude environment. The influence of the fuel aid on the combustion performance of a hydrocarbon fuel under different working conditions is investigated. Studies have shown that DMAZ and the fuel are mutually soluble at 20°C, and the mixed fuel after compounding has azide groups that can support combustion. The higher the residual gas coefficient, the higher the fuel combustion heat value and combustion efficiency. The combustion-supporting effect of the combustion-supporting agent is not only related to the content of the combustion-supporting agent, but also related to the residual gas coefficient. When the residual gas coefficient is 1.0, the combustion-supporting effect of DMAZ with a volume content of 0.5% can reach the maximum. When the volume content is greater than 0.5%, the combustion-supporting effect of DMAZ will decrease.
