Consideration of clogging in boundary-layer control system design

Abstract

AUGUST 1977 ENGINEERING NOTES 825 full-scale flight tests of the B-747 airplane, it is expected that the use of flight spoilers on both the DC-10-30 and L-1011 airplanes also would be effective in attenuating the trailing vortex behind both of these airplanes. Concluding RemarksBased on the results obtained in these investigations, it was found by ground-based tests and verified by full-scale flight tests that the existing flight spoilers on the B-747 airplane are effective as trailing vortex attenuators. Based on the results of wind-tunnel investigations of the DC-10-30 and L-1011 airplane models, the existing flight spoilers on both the DC-10-30 and L-1011 airplanes are also expected to be effective trailing vortex attenuators.
