更大的易用性和更高的密度使高能烃燃料成为低温燃料的有吸引力的替代品。目前正在探索在火箭和联合循环推进系统中使用高能碳氢化合物。除了明显用于推进目的外，燃料还用于冷却系统结构，使其再生到与目前可用的材料相当的温度。燃料的热稳定性限制了烃类燃料的使用，本文利用热诊断研究系统对RP-1、JP-10和四环烷的热稳定性进行了评价。研究发现，JP-10和RP-1具有合理的热稳定性，而高度应变的四元环在高压、凝相热应力下迅速降解。
Greater ease of use and higher density make energetic hydrocarbon fuels an attractive alternative to cryogenic fuels. The use of high-energy hydrocarbons in rocket and combined-cycle propulsion systems is being explored. In addition to its obvious use for propulsive purposes, fuel is used to cool system structures regeneratively to temperatures commensurate with presently availablematerials. Fuel thermal stability unfortunately limits theuse ofhydrocarbonfuels.Inthepresentcontribution,thethermalstabilityofRP-1,JP-10,andquadricyclaneisassessed using a system for thermal diagnostic studies. It is found that, whereas JP-10 and RP-1 exhibit reasonable thermal stability,thehighly strainedquadricyclanerapidlydegradesunderhigh-pressure,condensed-phasethermalstress.
