Design and Verification of Simulation Platform for Aircraft Engine Sensor Fault Diagnosis

A real-time simulation approach based on virtual instrument and rapid prototyping is proposed to solve the problem that aircraft engine sensors fault diagnosis approach can't be simulated rapidly,efficiently.And an ECU-in-the-loop real-time simulation platform with this approach is established.After plenty of validation,the platform is valuable for the development of aero-engine sensor fault detection,and it can takes a groundwork for a completely HIL platform,has some engineering value.
