A Hardware-Software Co-Design Real-Time Electric Simulative Load System for Airplane

In view of the demand for the different output power of generators in the relevant test projects during the flight test, this paper proposes a real-time aircraft electric simulative load system based on CompactRIO (cRIO)-embedded controller, which can adjust the aircraft power generation by controlling the access and the output status of the resistive load. The system is used to realize the test of the load capacity of the generator and the working state under different load conditions. At the same time, the heat dissipation of the resistive load is performed by using two cooling modes of water cooling and air cooling. In this paper, the overall architecture of the electrical simulative load system is described first, and the subsystems and software modules are introduced in detail according to the function. Finally, the function and technical indicators of the system are verified by experiments, which proves the feasibility of the design.
