| Abstract: | The heat loss formula of constant volume burner method is derived.The qualitative research and quantitative analysis of heat loss factors on constant volume burner method is carried out experimentally.The effects of some characteristics of propellant samples,such as pressure-rise rate,burning time,ignition ways,burning rate and so on,on the heat loss behavior are investigated.Results indicate that higher pressure-rise rate,shorter burning time,suitable ignition ways and higher burning rate can possess an excellent ability to reduce the heat loss. |
