Abstract:

This paper designs and develops a set of testing system for Steering Gear control of virtual flight test from 2.4 meter windtunnel based on RTX real-time extension module.The system which provides an important basis for the assessment of aerodynamic characteristics for flight major components collects Signals which are sent by Balance,Gyroscope,Steering Gear,photoelectric encoder.The paper introduces RTX real time module and hardware design firstly,and then describes the software design divided into 2 parts.Finally,in conjunction with a practical application,it is more time critical,more stable when running algorithm,higher accuracy and more user-oriented.

Key words: RTX;driver;PXI;steering gear control simulation
