A landing gear design automation tool has been developed and integrated in the conceptual multi-disciplinary optimization (MDO) environment at Bombardier Aerospace (BA). The tool allows an optimization to consider the landing gear integration at each design iteration. It uses design rules followed at BA to determine positions and ground contact points for the nose and main landing gears, while performing all necessary checks such as tip over, tail strike, and wing-tip strike angles. Subject to maximum loads from a set of predefined cases, the landing gear structure is sized and the tires and rims are selected from an embedded database. Once the landing gear is defined, a full kinematic analysis is performed to optimize the pivot axis and stowage of the gear in the fuselage. The tool was validated with actual data from several aircraft showing minimal errors in landing gear positioning and sizing (± 3%).
