WebApr 12, 2024 · In this paper, an 80-ton thrust liquid rocket engine (hereinafter referred to as an LRE) with a gas generator cycle, a 5:1 thrust throttling ratio, and an integrated flow regulator/gas generator (hereinafter referred to as an IFRGG) is analyzed. This LRE can be used during the first stage of launching, second-stage and upper-stage space missions, … WebHeavier rockets usually do better with shorter delays — otherwise the rocket might fall back down to the ground during the delay time. Motors marked with a time delay of 0 (e.g., “C6-0”) are booster engines. They are not designed to activate recovery systems. They are intended for use as lower-stage engines in multi-stage rockets.
