Abstract: In response to the question of whether it is reasonable to adopt a multi-engine-parallel scheme with dozens of engines for launch vehicles, a feasibility study about the multi-engine-parallel scheme with dozens of engines was conducted from the perspective of reliability. The reliability calculation model of mission success for multi-engine-parallel launch vehicles considering single point failure of a single engine was established based on series, parallel and voting systems. The influence anal... More
