Test research for flap skew on iron bird on a certain type of aircraft

This paper focuses on the flap skew test under the ground-based laboratory environment on the iron bird, taking a certain type of aircraft as an example to introduce the environment and skew malfunction principles about the flap skew test on aircraft. The mechanical devices used to simulate flap skew malfunction and recover flap skew malfunction are designed and applied in the ground simulation test of a certain type of aircraft. According to the results, the designed mechanism can be proved to be used normally and can carry out the flap skew test successfully.
