The calibration test of the high-thrust hydrogen-oxygen engine for the Long March 5B launch vehicle was successfully carried out on Monday. The engine will be delivered to the rocket assembly for this year's space station experimental module launch mission.
The calibration test carried out this time is the last engine of the Long March 5B launch vehicle.
Ma Liya, Director of the Science and Technology Division of the 101 Institute of the Sixth Academy of Aerospace Science and Technology Group, introduced that the high-thrust hydrogen-oxygen engine is the main propulsion engine independently developed by China and the thrust level is 50 tons, in addition each rocket of the Long March 5 series of launch vehicles will be equipped with two sets.
The calibration test is also the last opportunity on the ground to verify the performance of the engine. The completion of the test also means that the Long March 5B rocket has entered the final preparation stage before the transfer.
The high-thrust hydrogen-oxygen engine is used in the core stage of the Long March 5 series of launch vehicles,making it the most advanced cryogenic liquid rocket engine currently being used in China.
As scheduled, China will realize full completion of the construction of the space station this year. The launch of the Wentian experimental module and the Mengtian experimental module will be carried out by the Long March 5 series of carrier rockets.
