Analysis about Horizontal Abutment,Assembly and Transfer Techniques of Heavy Launch Vehicle Based on“Three Horizon”Test-launch Mode

Until now,the large-scale and heavy launch vehicles of our country have not use“Three horizon”test-launch mode.therefore,upon the investigate and survey of external alike programs,This paper proposes three kinds of technical proposal to solve the problem of horizontal abutment、assembly and transfer techniques which applies to the heavy launch vehicle based on“Three horizon”test-launch mode and“assembly on platform”may be the best one by its less demand of groud support devices and functions,Meanwhile which can make for the overall design of launch vehicle structure and test-building,and then,provide references to confirm the test-launch mode of the heavy launch vehicle.
