Aircraft Landing Gear Design and Development Introduction: Landing gear is one of the important systems in an aircraft. Important things needed while designing are minimum weight, minimum volume, reduced life cycle cost and short development cycle time. Its purpose is to provide a suspension system during taxi, take-off and landing, to absorb and dissipate the kinetic energy of landing impact, reducing the impact loads transmitted to the airframe, facilitate braking of the aircraft using a wheel braking system and provide directional control on ground using a wheel steering system. A landing gear system comprises of many structural and system components. The structural components include main fitting, shock absorber, bogie beam or trailing arm, axle, torque links, drag/side braces, retraction actuator, down lock mechanism, up lock, wheel, tire etc. The system components are brake unit, antiskid system, retraction system components. The nose gear will have addition elements like steering actuator and steering mechanism. Overview of Design and Development: The geometry, flotation requirements, mission requirements and operational requirements of the aircraft govern the landing configuration. The configuration design includes choice of number of wheels, tire sizes, pressures, type of shock absorber, landing gear layout, retraction kinematics and bay geometry design. Conceptual Design: A study of all design specifications and airworthiness regulations, performance, safety, cost, time frame, technology and resources, landing gear location, type of landing gear, steering concept, actuation mechanism and loads.
