Compiling load spectrum method for arrested deck-landing of carrier-based aircraft

The deck load spectrum is the key to longevity and damage tolerance design of carrier-based aircraft.Based on the specific ship load characteristics in aircraft landing process, the limitations of the existing compiling method are elaborated. Based on the multi-body system dynamics, this paper proposes a scheme for compiling the ship surface load spectrum, establishing the multi-body dynamics equations and simulation models, as well as carrying out simulation calculation. By analyzing the aircraft flight profile and the arrested landing mission profile, this paper identifies the main working conditions and their proportional relation for the arrested deck-landing mission. This paper also obtains the center of gravity of load spectrum and the transcendental curve, eliciting certain values in engineering application.
