Development of a Rolling Maneuver Spectrum from Statistical Flight Loads Data

Abstract

Absence of clearly defined antisymmetrical fatigue load spectra in military specifications has resulted in questions regarding the validity of rolling maneuver spectra applied to the B-1 design. In response, multiparameter flight loads data measured on the F-5A and F/105D aircraft were evaluated and used in the development of a probability of exceedance curve for the normalized wing tip helix angle. The normalized probability curve can be used in conjunction with any specified normal load factor spectrum and the airplane's maximum pb/2V capabilities to determine the occurrence rate of rolling velocity peaks. The approach should provide at least a first order estimate of possible rolling velocity spectra which can be applied in aircraft fatigue design for antisymmetrical maneuver conditions.
