Research on control strategy for ground extension and retraction test of landing gear

During take-off and landing of airplanes, landing gear control system features have huge influence on airplane safety. In this paper, Labview software, a virtual instrument from National Instruments Corporation is used as a development platform to apply its powerful G language programming ablity and friendly program design interface to develop system application in order to enable control of landing gear extension and retraction and perform landing gear-related ground tests under laboratory conditions.
