| Abstract: | Using certain long term stored tactics-type engine as research target,the poly(PO/THF co-polyether)/(BDNPA/F)/AP/Al composite solid propellant used in the engine was investigated.The properties of the propellant after long term storing in the engine were tested,and the charge interfaces were checked.The results show that,after this type engine was stored more than 20 years,the interface adhesion of the propellant was kept good,and the internal structure of charge was kept intact.The properties of the ignition engine can essentially meet the requirements and work normally after storing for 28 years. |
