Adams Simulation Saves Millions by Replacing Physical Testing in Aircraft Certification

摘要

Airframes are designed to deflect in response to aerodynamic and gravitational loads during flight These deflections in turn load the mechanisms riding on the airframe that move the primary flight control surfaces to maneuver the aircraft Tire airframe manufacturer must ensure that deflections of these mechanisms do not affect their operation. For example, the Airbus A400M elevator is connected to the horizontal tail plane (HTP) with eight hinges that form a straight line when the wing is undeformed. Seven of these hinges can float in the hinge line direction. When the HTP structure is loaded, it deforms, deforming the hinge line.
