Recently, China's current diameter of the largest, the largest amount of composite material dual pulse engine, the fourth Institute of China Aerospace Science and Technology Co., Ltd. successfully test the ground test of the test assessment of a large dual-pulse engine isolation structure, integrated ignition device And other key technologies, marking the Quartet's high-performance dual-pulse engine design and development technology has boarded a new level to enhance our country double pulse engine research and development level.
The double-pulse engine can effectively increase the average speed of the aircraft, increase the range and facilitate the flight control by reasonably adjusting the thrust distribution and the two-stage pulse interval.But this mode of energy management makes the structure much more complicated than the traditional engine, Pulse spacing, thermal shock and a series of technical difficulties, the domestic technology in the area almost blank.Development team to overcome the new technology, the difficulty of the task tight and many other difficulties, to determine the key technology research and demonstration to verify step by step research route Through a series of individual tests and simulated engine test verification, the research team achieved a breakthrough from optimization of the program to successful flight within one year, making major breakthroughs in research and flight tests.
Through sincere cooperation and brave innovation, the team members gradually master a number of key technologies through continuous improvement and optimization of the engine program, and finally designed a completely independent innovation of dual-pulse engine structure to fill a gap in a number of domestic technologies to apply for national defense invention patents More than 20, in the domestic and foreign key periodicals, academic conference published more than 10 articles, laid the hospital in the domestic double pulse engine technology absolute leading position.
