Since the theory of aircraft engine electrical system was more complicated and difficult to master for maintenance support personnel, a novel scheme of simulation system design for maintenance training was proposed. The mechanical frame of the system was based on the original aircraft engine and electrical parts of the engine were reconstructed by DSP digital technology. As the core of communication the integrated console based on embedded Linux was developed under Eclipse environment. The experimental equipment environment with virtue simulation and strong interaction was constituted by employing the electric network technology. The system realized the functions such as comprising theory teaching, state simulation, fault setting and training testing with electrical network technology.
