Research and Simulation of Bidirectional Conversion between Electric Energy and Hydraulic Energy of Aircraft Secondary Energy

Modern aircraft toward the intelligent (driverless), high stealth, the new concept of airborne weapons (phased-array radar, laser weapons), information integration and multi-composite features (a multi-purpose machine) the direction of these advanced modern. The technology has led to a substantial increase in the number of on-board electronic equipment, resulting in a dramatic increase in the demand power of the aircraft at various stages. The demand for power drawn from the engine is increasing and the thermal load also increases substantially, and the demand for the aircraft is getting higher and higher. According to the demand of aircraft for high power, the characteristics of aircraft hydraulic system and related components of aircraft electrical system are analyzed, and the operating characteristics of components and the synergy between the two subsystems are analyzed. AMESim modeling and simulation software was used to model and analyze the hydraulic system of aircraft. The corresponding characteristic curves were obtained, which indicated that there was a model that can be controlled cooperatively between the two subsystems of the aircraft, which provided the basis for the optimized utilization of the energy of the aircraft. It verified that the conversion of different energy between the use of the feasibility. At the same time for the latter part of the design provides a theoretical basis. The feasibility of conversion and utilization of aircraft electric energy and hydraulic energy is provided. In view of this feasibility, a bidirectional energy conversion device is designed and a scheme of energy conversion is proposed. Detailed calculation and calculation of parameters are carried out. At the same time, the device has different working modes for different working conditions. The AMESim software was used to simulate the conversion device and verify the function and operation characteristics of the device under different operating conditions.
