Abstract:
Tests have been made in the Royal Aircraft Establishment 10-ft x 7-ft High-Speed Tunnel on three half-wings having a sweepback of about 50 deg on the quarter-chord line and 7.5 per cent thick sections. Two of the wings had sections of the RAE 101 shape (maximum thickness at 0.31c) and differed principally in aspect ratio (3.1 and 3.5). The third wing had an aspect ratio of about 3.1 but a different section shape with its maximum thickness further aft at 0.4c and, as shown by the results of the tests, an effectively sharper nose than for the RAE 101 shape.
