Optimization of Manufacturing Process of Booster Rocket to Reduce the Cost
Abstract: The spacecraft is launched into earth orbit or beyond with the help of boosters. After entering into earth orbit, the booster leaves the spacecraft and falls back into the earth after reaching a point called as booster engine cut-off (BECO). The spacecraft continues flight after leaving the booster with upper stage engines. Some of the boosters are recovered, reconstructed and reused. The boosters used for space shuttle are recovered and …
