In aerospace engineering, the propellant m … In aerospace engineering, the propellant mass fraction is the portion of a vehicle's mass which does not reach the destination, usually used as a measure of the vehicle's performance. In other words, the propellant mass fraction is the ratio between the propellant mass and the initial mass of the vehicle. In a spacecraft, the destination is usually an orbit, while for aircraft it is their landing location. A higher mass fraction represents less weight in a design. Another related measure is the payload fraction, which is the fraction of initial weight that is payload. It can be applied to a vehicle, a stage of a vehicle or to a rocket propulsion system. vehicle or to a rocket propulsion system.
, 추진제 질량비는 목표 궤도에 도달한 로켓의 무게를 발사 전 로켓의 무게로 나눈 다음에 1을 그 값에서 뺀 값이다. 쉽게 말하면 다. 이 추진제 질량비가 커질 수록 페이로드의 질량은 줄어든다.
