Preliminary study of the rocket-ramjet-rocket concept for HTO space plane
Abstract
A two-stage-to-orbit rocket-ramjet-rocket concept intended to extend the operating Mach range of ramjets as widely as possible is proposed. The ramjets are of subsonic combustion mode using liquid hydrogen as fuel and operating from Mach 0.8 to Mach 6.5-7. The vehicle takes off from the ground by using liquid tripropellant rockets as boosting power. The ramjets are ignited at high subsonic speed and take over fully at Mach 2. After Mach 6.5-7, the LH2-LOX rocket engines are used to propel the vehicle to orbit.
