Abstract: Purpose: The aim of this study is to evaluate the structural responses proposed by military specifications with real test conditions and also compare the effects of usage ANN predicted and military specification loads in design of aerospace structures. Theory and Methods: Vibration responses in structural design is used as PSD in the frequency domain. Loads for structural design purposes are calculated with random loads using PSD data between 20-300 Hz frequency bands. Results: An aerospace structure is designed according to the ANN predictions, military specification proposal and experimental design loads. Supports designed based on experimental and predicted loads are lighter than the support designed according to the military specification load. Conclusion: It was observed that military specification loads exhibit conservatism. This conservatism makes the aerospace structures complex and heavier. Also, more engineering effort and production cost is occurred since the loads are high with respect to real environmental conditions.
