An investigation has been made in the Langley 4- by 4-foot supersonic pressure tunnel at Mach numbers of 1.61 and 2.01 to determine the aerodynamic characteristics of a spoiler-slot-deflector control on a 45 degree sweptback wing having an aspect ratio of 3.5, a taper ratio of 0.3, and an NACA 65A005 airfoil section. The model was equipped with a 15-percent-chord spoiler-slot-deflector extending from 13 o 78 percent of the wing semispan. The spoiler and deflector were hinged along the 60- and 75-percent-chord lines, respectively. Tests were made at a Reynolds number of 3,000,000 (based on the mean aerodynamic chord of the wing) and covered ranges of angles of attack from -3 to 15 degrees, spoiler projections from 0 to 8.0 percent chord, and deflector projections from 0 to 7.6 percent chord.
A wind-tunnel investigation has been made at low speed in the Langley 300 MPH 7- by 10-foot tunnel to determine the effect of deflector projection on the control effectiveness of spoiler-slot-deflectors on a 30 degree sweptback wing-fuselage model equipped with either a 15-percent-chord spoiler or a spoiler-slot-deflector that extended from the 20- to the 99-percent-semispan station of the right ring. The wing had an aspect ratio of 3, a taper ratio of 0.5, and NACA 65A004 airfoil section. The tests were made at angles of attack from -4 to 24 degrees at Mach number of 0.26 for control projections from 0 to 12 percent chord. The deflector of the spoiler-slot-deflector configuration was tested at projections from zero to a projection equal to the spoiler projection at each spoiler projection.
