Azide basis and nitrato basic content solid propellent

摘要

PURPOSE: To obtain a solid propellant having high specific impulse and burning velocity and lowered pressure index by compounding a lead compound and carbon to a composition containing a specified fuel binder and oxidizing agent. ;CONSTITUTION: This solid propellant is produced by compounding a lead compound and carbon to a composition composed of a fuel binder composed mainly of a prepolymer having azido group and nitrato group and an oxidizing agent consisting of nitramine. Among the azido group-containing prepolymers, 3,3-bis(azidomethyl)oxetane has the highest azido group content and gives high energy, however, the polymer is solid at normal temperature. It can be converted into a polymer exhibiting liquid state at normal temperature by copolymerizing with 3-nitratomethyl-3-methyloxetane containing nitrato group and expressed by formula. In the formula, R₁ is CH₂N₃, R₃ is CH₂ONO₂ and R₃ is CH₃.;COPYRIGHT: (C)1996,JPO
