The equations of motion for an airplane penetrating a gust are derived using a few simplifying assumptions. Calculations of loads for different static longitudinal stability on two German airplane models, HC 45 and HS 122, are compared with flight tests. Good agreement is obtained between the trend of the flight tests and the calculated values; however no absolute comparison was possible between the flight tests and calculations.

Through the use of difference equations and matrix notation a systematic procedure is developed for the calculation of the structural response of an aircraft flying through a gust. The method takes into account wing bending and twisting flexibilities, fuselage flexibility, vertical and pitching motion of the airplane, and some tail forces. Strip theory is used, but approximate three-dimensional and compressibility corrections can be made without difficulty. Either sharp-edge or arbitrary gusts may be treated.
