The landing gear door of a business jet recently experienced flutter during takeoff. In the present work, a flat plate with a hinged edge boundary condition and a small interior region with a pinned boundary condition is considered as an idealized model of a landing gear door. Aeroelastic stability of the plate is predicted using the vortex lattice method (VLM) for the entire range of possible actuator placements. Results show that the location of the actuator on the door’s surface significantly alters the critical velocity, type of instability (flutter or divergence) and the structural mode that becomes unstable.
