The Academic And Experimental Research On The Plasm-Production Solid Rocket Motor

Reentry bait with cascade is an important means of strategic missile-warhead penetration .Eletron consistence and their distribution is the sticking point of the plasm production implement. In this article, theoretical analysis and experimental investigation of the Plasm-production Solid Rocket Motor is implemented in thermodynamic calculation, eletron consistence theoretical calculation and experimental system design.Conventional thermodynamic calculation always can not achieve convergence for coagulum. In this article, this problem is well resolved through thermodynamic calculation including coagulum.In this article, statistical summation method is used to obtain system free energy expression . And the equation to calculate ionization rate is obtained at the base of the principle that the system free energy is the least versus the particle number.This paper introduces the experiment of measuring flow field of mini-solid-rocket motor with electrical probe .Introducing the instruments , the scheme and the method. Finally, we analyse the data, and we found some rule about plasma with jet. After discussing the results, we present some problems that should be researched in the future .At last, through the calculation and analyses of motor performance and eletron consistence, the influence of working altitude ,firebox pressure impurity content and the mental component content in the composite propellant on calculation result is abtained.
