Of the hundreds of structural parts and hundreds of moving parts on a commercial airplane, there are very few that are both structural and moving that also face the aerodynamic and mechanical-performance demands placed on landing gear doors. Among the largest moving structures on an aircraft, they must perform flawlessly under all flight conditions and meet a host of contingency requirements in the event of aircraft power loss or landing-gear failure. Recently tasked with the job of designing and fabricating the main landing gear door (MLGD) for the Airbus (Toulouse, France) A350 XWB, Daher-Socata (Paris, France) opened its doors to HPC and revealed much of the engineering knowledge behind these complex composite structures, acquired during its long history in landing gear door production.
