Helicopters have to operate in a complex environment during shipboard landing, illustrated in Fig. 1, making it a challenging task for the pilots. Conducting flight trials in this environment is expensive, therefore an accurate helicopter/ship dynamic simulation capability is highly desirable. Our overall objective is the development of a high fidelity physics-based simulation capability, and its application to simulate approach to landing, hover over the deck and actual landing on the moving deck. The overall objective was accomplished in three distinct stages. First stage consisted of developing a mathematical model for the principal components of the problem: (1) a coupled rotor/fuselage/landing gear model, (2) a flight control system for stability augmentation and trajectory tracking, (3) a high-fidelity ship airwake modeling capability, and (4) a dynamic ground effect model. In the second stage, computationally efficient reduced order models (ROM)/surrogates were developed for the ship airwake model. In the third stage, all the components were integrated into a global simulation framework.
