Aircraft Dynamic Response to Damaged Runways.
Abstract
The three papers included in this Report were presented as the first stage of a study of the potential problems of aircraft dynamic response to damaged and repaired runways, and arrived at the following general conclusions. For small aircraft with relatively simple landing gear, the operation over nominal repairs was dominated by rigid body motions of the aircraft. The prediction of those motions was possible and compared reasonably well with experimental data. For large aircraft or aircraft with large external stores, the prediction of detailed loads in critical areas has met with limited success so far. Since landing gear equations are highly nonlinear, the prediction of aircraft dynamic response has required time-consuming numerical integrations. Also, the behavior of large external stores can be affected by nonlinear effects (such as rigging loads), and both landing gear and external stores nonlinearities are affected by aircraft servicing procedures and by the ambient environment. Papers presented at the 49th Meeting of the Structures and Materials Panel, Porz-Wahn, Germany, October 1979. (Author)
