COMPUTATIONALLY ECONOMICAL METHODS FOR LANDING GEAR NOISE SIMULATIONS
R. Spencer, CFMS Ltd, United Kingdom; M. Allan, Zenotech Ltd, United Kingdom
Landing gear generates lots of noise, but traditional aero-acoustic simulations are very expensive. In this paper, two cheaper simulation methods are applied to a landing gear acoustic test case and compared to the literature. First, an LES simulation using an Octree mesh and no grown boundary layer mesh is used. Secondly, a stochastic simulation using the Fast Random Particle Method is used.
