Abstract : PROCEDURES FOR DESIGNING AIRCRAFT FOR THE COMBINED EFFECTS OF VERTICAL, LATERAL, AND LONGITUDINAL TURBULENCE BY THE APPLICATION OF POWER SPECTRAL TECHNIQUES ARE DEVELOPED AND OUTLINED. The present state-of-the-art of this technical area is established and evaluated by reviewing and extending current methods used or proposed for predicting the response of aircraft due to combined effects of the three components of atmospheric turbulence. Requirements for solving the problem are identified and recommendations are made with respect to major problem areas such as: description of the turbulence environment, determination of the frequency response function of the structure, and methods of combining the effects of vertical, lateral and longitudinal turbulence components to theoretically predict aircraft response.
