Author: [Your Name] Date: [Current Date] Course/Institution: [Your University/Organization] Abstract The landing gear is a critical airframe subsystem enabling safe takeoff, landing, and ground maneuvering. This paper presents a systematic approach to the design of aircraft landing gear, covering configuration selection (tailwheel, tricycle, tandem), structural layout, shock absorber mechanics (oleo-pneumatic struts), retraction mechanisms, wheel and brake systems, and steering control. Emphasis is placed on design drivers: crashworthiness, weight minimization, fatigue life, and regulatory compliance with CS-25/FAR Part 25. A case study of a typical light aircraft tricycle gear illustrates load calculations and component sizing. The paper concludes with emerging trends, including electric taxi systems and lightweight composites. 1. Introduction Landing gear design directly affects aircraft safety, performance, and operational cost. Unlike aerodynamic surfaces, landing gear is used only briefly per flight, yet failure can be catastrophic. Approximately 30% of airframe structural damage occurs during landing and ground operations. Therefore, the design must balance conflicting requirements: absorbing high kinetic energy, minimizing drag and weight, stowing compactly, and ensuring reliable extension/retraction.
