The integrated propulsion system pylon is a statically indeterminate aircraft engine supporting structure with complex structural features and load-transmitting characteristics. The interface load measurement is a key part of the pylon static test. A new load sensor for pylon interface load measuring is developed in this paper. The load equation and static characteristics of the proposed load sensor are obtained and analyzed by strict calibrating tests. Results show that the load sensor has good linearity and repeatability, and its overall accuracy is within 3.30%. The load sensor was applied to the interface load measurement of the 67% limit load test phase of the integrated propulsion system pylon static test. Experimental data analysis showed that the proposed load sensor can achieve a measuring accuracy of 10%; the measured data are reliable and valid for load analysis of the integrated propulsion system pylon.
