The Test Verification Design Method Based on Rapid Prototyping Technology of Aero-engine☆

Abstract For the rapid test verification of aero-engine control and gas path fault diagnosis algorithm, the rapid prototyping hardware in the loop test verification method of the aircraft engine function algorithm module was designed, which based on the virtual instrument language and rapid prototypingtechnology.CompactRIO and its extension boards were utilized to build the rapid prototyping test verification platform for aircraft engine function algorithm, the control algorithm and the gas path fault diagnosis algorithm was deployed to the hardware in the loop whichbased on rapid prototyping, for the simulation of the algorithm on the platform.Finally, as an example of a turbofan engine PID control algorithm and gas path fault diagnosis algorithm, hardware in loop simulation test verification was carried through the rapid prototyping of platform. The results show that the rapid prototyping platform and its design method can realize the algorithm verification fast and flexible.
