9机并联 朱雀三号可复用火箭一级动力系统试车成功

Core Viewpoint - The successful ground test of the first-stage propulsion system for the Zhuque-3 reusable launch vehicle marks a significant milestone in its development, laying a crucial foundation for its upcoming maiden flight [1][3][8] Group 1: Test Details - The ground test involved a 9-engine parallel hot test using the self-developed Tianque-12A liquid oxygen-methane engine, achieving a total thrust of 7542 kN [3] - This test is considered one of the most important large-scale ground tests in the development of the Zhuque-3 launch vehicle [3][5] - The test closely simulated the actual flight conditions of the rocket, covering all aspects of the launch process, including propellant loading and engine start-up [5][8] Group 2: Vehicle Specifications - The Zhuque-3 launch vehicle is a large liquid oxygen-methane rocket with a takeoff weight of approximately 570 tons and a total length of about 66 meters [3] - It features nine Tianque-12A engines working in parallel, an auxiliary power system, and deployable grid fins for controlled recovery landing [3] Group 3: Importance of the Test - The propulsion system test is referred to as "non-launch ignition," representing one of the most complex and challenging ground tests in the rocket development process [8] - It is a critical prerequisite test before the rocket's maiden flight, ensuring the system's compatibility and process rationality [5][8]
