| Abstract | Abstract Computational simulations of aerodynamic characteristic s of the Common Research Model (CRM), representing a typical transport airliner, are conducted using C FD methods in close proximity to the ground. The obtained dependencies on bank angle for aerodynamic forces and moments are further used in stability and controllability analysis of the lateral-directional airc raft motion. Essential changes in the lateral-directional modes in close proximity to the ground have been identified. F or example, with approach to the ground, the roll subsidence and spiral eigenvalues are merging crea ting the oscillatory Roll-Spiral mode with quite significant frequency. This transformation of the lateraldirectional dynamics in piloted simulation may affect the aircraft responses to external crosswind, modify ha ndling quality characteristics and improve realism of crosswind landing. |
