Abstract:

Prediction of load spectra for airplanes hinges on the existence, in a statistical sense, of a regularity in certain features of the overall operation of the airplane. The most important of these features are A objective of operation, e.g. transportation, combat-interception, combat-ground attack, combat-patrol and surface attack, reconnaissance, etc B Mission operational pattern, involving mission flight plan schedule of speeds, altitudes and ranges, mission maneuvering schedule, schedule of the minimum number and expressed purpose of flight maneuvers required for achievement of the operational objective, maneuvering situations circumstances pertaining to each particular flight maneuver required for achievement of the operational objective of the mission. Considerations pertaining to selection of typical missions are reviewed briefly. Mission patterns are reviewed for typical transport, combat- interception and combat-ground attack operations, and corresponding maneuvering schedules and maneuvering situations are discussed. Procedures for derivation of distributions for maneuvering load factors from some typical maneuvering situations are proposed. Certain important human engineering aspects of the pilot and their influence on the load spectrum are discussed.
