KC-100 is composite small aircraft which developed for BASA(Bilateral Aviation Safety Agreement) agreement and making inroads into the North America market. Engine Mount Structural(EMS) installed in KC-100 takes charge of supporting the Engine and transmitting the loads of Engine and nose landing gear. For analyzing the EMS, Linear gap elements, RBE 2 elements and MPC are used to realize the bulkhead boundary condition, contact condition between Engine and EMS, and appropriate the load condition. Load analysis FE model is used the EMS design tool, detail FE model reflected the weld joint section is used to analyze the stress distribution. Also, static test is performed to verify the structural analysis results. The comparing the results between the structural analysis results and test results ascertain the high accuracy, the process of EMS structural analysis and test may help the design the small aircraft EMS.
