A liquid bipropellant rotating detonation rocket engine was successfully test fired. The 6.5-in.-diam engine operates on a mixture of rocket-grade hydrogen peroxide and triglyme. Ignition is accomplished hypergolically, with the addition of a promoter to the fuel. Eight cases of spontaneously initiated, single-wave, rotating detonations were observed. Detonation wave speeds were near or exceeding Chapman–Jouguet calculations. Evidence of condensed-phase reactions was also seen, damaging hardware in short order. Both a rotating detonation and a bulk-slapping mode characterized the engine operation.

超高能点火液体双推进剂旋转爆轰火箭发动机的实验研究

液体双推进剂旋转爆轰火箭发动机成功试射。直径为6.5英寸的发动机使用火箭级过氧化氢和三甘醇二甲醚的混合物运行。通过向燃料中添加促进剂，以高曲线方式实现点火。观察到八例自发引发的单波旋转爆炸。爆炸波的速度接近或超过Chapman–Jouguet的计算。还发现了冷凝相反应的证据，短期内损坏了硬件。旋转爆震和大量拍击模式都代表了发动机的运行。
