Design of Landing Gear for Medium Altitude Long Endurance (Male) Unmanned Aerial Vehicle

Abstract

This paper examines the procedure adopted for the design of UAV landing gear. Aircraft landing gear serves as a mechanism to support weight of the aircraft during landing, take-off , taxiing and also provide a shock absorbing function. The design of landing gear for the Medium Altitude Long endurance unmanned Aerial Vehicle is simple and it is base on safe life and fail safe concept and at the same time, make optimum selection and used of high strength materials for the design.This design considerations for this landing gear are significantly different, but past design procedures were used as guide to this design .Various landing gear configurations and types are in used today. The most common landing gear use for UAV is the fixed tricycle arrangement with one nose wheel (NLG) and two main wheels (MLG) at the rear. The retractable tricycle type was adopted for this design. The most attractive feature for this design is the improve stability during braking and ground maneuvering. The result obtain from this study indicate that the landing gear stability of the UAV could be improve with longer wheel axle, by increasing the wheel track.The approach used for the design, of the landing gear for this Medium Altitude Long Endurance UAV, follows the recommendations from previous designs of UAV landing gear and federal Aviation Regulation (FAR).
