Design Optimisation Of Landing Gear's Leg For An Un-Manned Aerial Vehicle

摘要

The landing gear is a structure that supports an aircraft on ground and allows it to taxi, take-off, and land. In fact, landing gear design tends to have several interferences with the aircraft structural design. Now a days the weight of landing gear has become an important factor. Efforts are being made to reduce the weight of the aircraft and consequently increase the payload. This paper presents an approach to optimize the design of landing gear's leg of an Unmanned Aerial Vehicle (UAV) made of ASM7075-T6 material adopted from Aerospace Specification Metals(ASM). First the structural behavior is tested using the structural analysis when subjected to behavior constraints. Optimization process is carried out iteratively to minimize thickness of landing gear's leg which results in the minimum weight of landing gear
