Taxiing, Take-Off, and Landing Simulation of the High Speed Civil Transport Aircraft

摘要

The aircraft industry jointly with NASA is studying enabling technologies for higher speed, longer range aircraft configurations. Aircraft response during ground operations, although often overlooked, is a concern due to the increased fuselage flexibility. This paper discusses modeling and simulation of the High Speed Civil Transport aircraft during taxiing, take-off, and landing. Finite element models of the airframe for various configurations are used and combined with nonlinear landing gear models to provide a simulation tool to study responses to different ground input conditions. A commercial computer simulation program is used to numerically integrate the equations of motion and to computer estimates of the responses using an existing runway profile. Results show aircraft responses exceeding safe acceptable human response levels.
