Design and Implementation of Integrated Test System for Helicopter Electrical Power Based on Virtual Instrument

In this paper,the design and implementation of the test system for characteristic parameters of helicopter power is introduced.Different algorithms for testing the characteristic parameters of helicopter power in the field is designed by LabWindows/CVI6.0,which is a programming language of virtual instrument.By the method,the multi-channel quick data acquisition and high performance parallel data acquisition are realized.The use of the virtual instrument panel makes the graphical user interface very clear and simple.Experiment in the helicopter electrical power system indicates that the system has reliable performance for the measurement of steady and transient parameters.It also has good prospects for extensive application to other measurements.
