This report describes the effects of atmospheric turbulence on low altitude flight performance. Pertinent problem areas are: (1) Aircraft displacement by gust, and (2) Induced gust load factor experienced by the penetrator. The LTV-developed LAP (Low Altitude Penetration) model was used to simulate penetrator performance under hypothesized atmospheric turbulence conditions. Section 2 of this report presents the methodology for evaluation of aircraft response to atmospheric turbulence, while Section 3 discusses the gust effect simulation techniques. The LAP simulation results, as functions of aircraft characteristics, terrain-following system characteristics, terrain roughness, operational parameters, and gust level, are described in Section 4. The data format (in terms of aircraft speed, forward terrain look distance, command/average terrain clearance, terrain roughness, RMS-gust velocity and RMS-delta g load factor) for potential LAP performance trade-offs are also described.
