Investigation of the Hinge-Moment Fluctuations of a 0.20-Chord Plain Ailerons on a High-Aspect-Ratio Wing in the Langley 8-Foot High-Speed-Tunnel

Abstract

Photographic records of hinge moment fluctuations were made by means of an oscillograph connected to an electrical strain gage. At super critical Mach numbers, frequencies of the order of magnitude of 50 to 100 cycles per second were observed for the hinge-moment fluctuations of the aileron of the model. For a 104.5 foot span airplane, full scale hinge-moment-fluctuation frequencies are indicated to be of the same order of magnitude as the wing natural frequencies.
