Mechanical System Performance Analysis of Commuter Aircraft's Rear Landing Gear Design for Unpaved Runway

Landing gear design of this commuter aircraft was developed from the previous model, to carry more passengers. The total load of the aircraft will increase as passenger capacity increases. With a variety of runways in Indonesia, it is necessary to have a good landing gear performance for landing on a paved and unpaved runway. Performance of the landing gear design is analyzed through kinematics and dynamics methods. Main concern of this analysis is to find the capability of the landing gear shock absorber to damp the vibration response due to the impact of the landing gear system with the wavy surface of the unpaved runway, as well as the actuator ability as the extension and retraction mechanism driver. The analysis concluded that the landing gear design capable to perform during landing on a paved and unpaved runway, with a modification of the shock absorber and actuator design.
