WebFeb 15, 2024 · The best method to do this is rocket staging. “Staging” means to construct a rocket such that some tanks and/or engines are integrated into one stage, which can be jettisoned after use thereby reducing the mass to be further accelerated. Figure 3.1 depicts four types of rocket staging, where parallel staging and serial staging are the most … Webenable the uppermost stage to attain a very high altitude. This is accomplished by dropping mass throughout the burn so the top stage can be very light and coast a long way upward." Direct vs Indirect Staging There are two methods of staging rocket motor.
