Design Drop Weight Impact Testing for Landing Gear UAV LSU (LAPAN Surveillance UAV) Series

The use of UAV (Unmanned Aerial Vehicle) by government and private institutions has been widely practiced. One is for monitoring needs, mapping an area to another, and more specific military needs. UAV carry a variety of sophisticated electronic equipment, and landing gear must be capable of supporting the load. Absorbing impact energy is essential to prevent damage to the equipment. The landing gear drop test simulates the stiffness of the landing gear to receive an impact load when the aircraft lands. The primary purpose of the tool's design is to facilitate the effective and efficient research and development of landing gear design in the future. This study's landing gear drop weight test was designed for all types of LSU unmanned aircraft (Lapan Surveillance UAV). Landing gear drop weight is designed with several systems to support the ability to determine the speed before the impact, impact force, and deformation on the landing gear strut as a parameter for future landing gear research. This test tool utilizes gravity as an impact propulsion. The test equipment design refers to the CASR 23 standard test. This study compared the test equipment design solutions and the construction deflection analysis to ensure the design results could be made. The bending value of the hoist plate on the rig design that has been made is 57.7 MPa. The value of critical buckling in the rig column is 28,353 kN.
