The salvage for the floating bodies under high sea conditions are essential for offshore landing sites in aerospace engineering.Utilizing physical model pool experiment,the individual net experiment and floating body net experiments were conducted under sea conditions of level 5 waves and currents.Comparative analysis was then carried out to elucidate the mechanical characteristics of the net and factors influencing capture under high sea conditions.Results indicate that the maximum force on the net when the floating body enters the net is approximately twice that of the individual net.At a sailing speed of 0.60 m/s without the assistance of liftting ropes,capture failures are prone to occur,while at speeds of 1.11 m/s and above,successful capture is generally achievable.The use of lifting ropes significantly improves the success rate of capture at low speeds.There exists a critical salvage speed of approximately 2.06 m/s,beyond which the force on the net will substantially increase.
