Abstract:

An electric landing assist device for shipborne helicopter is designed to address the problems of significant capture impact and high energy consumption of aircraft ship integrated secure and traverse(ASIST) system. The performance requirements of landing assist device during the capture and transshipment tasks are presented by analyzing the working conditions. According to this, a transmission scheme of electric landing assist device is proposed. A dynamics model of the transmission system is established based on the theory of power bond graph; The proposed dynamics model is compared with the hydraulic landing assist device through the simulation test. The results show that the capture speed is reduced by about 92%, and the maximum impact force is reduced by about 94%. The electric landing assist device can execute the helicopter transshipment tasks with an external load of 21kN and reduce energy consumption by about 29%. These research achievements are of great significance for broadening the application scope and reducing the energy consumption of ASIST. In addition, the introduced modeling method, which considers both the dynamic and energy consumption characteristics, also provides a reference for the dynamic modeling of other complex mechanical systems.
