Aiming at the mechanical-thermal coupling test of full size hypersonic aircraft,a mechanical-thermal coupling test loading scheme for full size wing is designed.The integrated heater designed together with the loading system and the heating system solves the problem of mutual interference between the heating system and the loading system in the mechanical-thermal coupling test and the difficulty of on-site installation,simplifies the field procedure of the test,and improves the reliability and accuracy of repeated loading in the mechanical-thermal coupling test.This technology has been successfully applied to the ground mechanical-thermal coupling test of a certain type of verification aircraft,which lays a foundation for the development of hypersonic aircraft.
