EEA基热塑性固体推进剂制备及其性能研究
Preparation and Properties of EEA-based Thermoplastic Solid Propellant
摘要
Abstract
Three-component EEA/AP/AI based thermoplastic propellant with 88％solid content was prepared by acoustic res-onance without propeller mixing,and the leveling property of the slurry meet the requirement of vacuum casting technology.The microstructure,mechanics,combustion,safety and rheological properties of EEA-based thermoplastic propellant were car-ried out.The results show that the prepared EEA-based three-component thermoplastic propellant with high solid content has a dense and pore free interior,and the solid filler is evenly distributed.The burning rate pressure exponent of EEA-based propel-lant is 0.28,which occurs near-plateau combustion over the low pressure range(1-7 MPa).The time-temperature depend-ence of EEA-based propellants is quite different from that of conventional HTPB/high energy thermosetting propellants,which is no limitation on"shelf life"of slurry,and solid liquid transformation can be achieved with temperature changes.The mechani-cal properties of the propellant can meet the requirements of structural integrity in standard test engine test,and its safety per-formance is equivalent to that of three-component HTPB propellants.The comprehensive properties of EEA-based propellants are much higher than that of the developed thermoplastic propellants,which provides a technical approach for the development of solid propellants towards insensitivity and greenness.关键词
