Abstract:

A mathematical model is formulated for the ship Fresnel lens optical landing systemFLOLSpilotaircraft system, considering deck motions and air turbulence inputs. Performance of this model in terms of terminal conditions in the vertical plane ramp clearance, impact velocity, dispersion of the touchdown point and aircraft longitudinal motions in the groove prior to touchdown is consistent with and validated by actual performance. The terminal dispersions are statistically combined to yield probabilities of potential ramp strikes, landing gear failures, and bolters, which, when put through a simplified pilotLSO decision model, yield probabilities of successful pass, bolter rate, and accident rate. Again, these rates are consistent with actual experience and are used as criteria for evaluating various competing systems. The effects on landing performance of variations in piloting technique, FLOLS stabilization methods, intensity and spectral form of ship motions, and gust inputs are computed. The variations tested and their resulting relative performance are described. Tentative conclusions are drawn from the analysis relating to possible improvements to the present operational recovery system.
