| Abstract: | On the basis of analysis of the height characteristics and the specific impulse characteristics of both choked and unchoked ram rocket, the requirements of the fuel rich propellant for adjustable fuel mass flow gas generator, especially for the unchoked gas generator were proposed. The fuel rich propellant used for the unchoked ram rocket should has high burning rate exponent, appropriate burning rate, low flammability limit and steady combustion properties. The methodology to modify the performance of the fuel rich propellant was studied. |
