LOW ALTITUDE PENETRATION PARAMETRIC STUDY. PART II. EFFECTS OF ATMOSPHERIC TURBULENCE ON LOW ALTITUDE FLIGHT PERFORMANCE.
Abstract
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.
