新型负载燃速催化剂对 NEPE 推进剂燃速的影响
Influence of New Loading Burning-Rate Catalysts on Burning-Rate of NEPE Propellants
摘要
Abstract
Two loading burning-rate catalysts BC-1/CN and BC-2/CN introducing a new type of carbon nanomaterial CN as the carrier were designed.The influence of loading burning-rate catalysts on the thermal decomposition behavior of AP was studied by the TG-DSC coupling method.Effects of variety and content of loading burning-rate catalysts on the combustion properties of NEPE propellants were investigated.Results show that the BC-1/CN and BC-2/CN can enhance the catalytic action of BC-1 and BC-2 on the thermal decomposition of AP and significantly reduce the decomposition temperature of AP.With the increase of CN content in the catalyst,the burning-rate of NEPE propellants under 15 MPa increases from 15.72 mm/s to 24.68 mm/s,which increases by 57%,while the pressure exponent also decreases from 0.60 to 0.46.When the mass fraction of CN in the loading burning-rate catalyst is 10%,the burning-rate of NEPE propellant is up to 34.8 mm/s,while the process performance of the propellant slurry is not significantly deteriorated and the comprehensive effect is the best.关键词
