Abstract

Vibration and buffeting are important flight test subjects for civil aircraft airworthiness certification. It is an important task to determine the initial buffeting boundary of the aircraft ac-cording to the flight test results. This paper introduces the time domain analysis method of initial buffeting data and the optimized frequency domain analysis method: including the data preprocessing in the frequency domain analysis, the determination of analysis standard, and the theoretical analysis idea of determining the initial buffeting according to the variation regulation of frequency domain vibration peak with angle of attack; the initial buffeting evaluation standard of subjective evaluation combined with theoretical analysis is proposed; according to the determined initial buffeting standard, the initial buffeting test data of an aircraft are processed, and the initial buffeting boundary is given; finally, a method of extending the 1.3 g buffeting envelope according to the initial buffeting boundary is given.
