The cockpit of the transport aircraft is located inside the nose,and the conventional test loading equipment is difficult to fix.How to accurately simulate the pilots loading on the mechanical control device in the function inspection test of the whole aircraft control system has become an urgent problem to be solved in this type of test.In order to check the function of the rudder surface while assessing the static strength of the aircraft structure,a new test technology of the rudder surface function inspection for the whole aircraft static test was proposed.The automatic switching technology and real-time monitoring technology of multi-directional turning angle were used to simulate the pilots control process and the loading on the rudder surface,the control force curves and the rudder surface response curves were obtained,and the loading,control and measurement problems were successfully solved in the test.Finally,taking the large-scale fire-fighting/water rescue amphibious aircraft control system function inspection test as the research object,the test was successfully completed by the new method.So the method meets the test requirements.
