LOW-SPEED INVESTIGATION OF THE LATERAL-CONTROL CHARACTERISTICS OF A FLAP-TYPE SPOILER AND A SPOILER-SLOT-DEFLECTOR ON A 30° SWEPTBAGK WING-FUSELAGE MODEL HAVING AN ASPECT RATIO OF 3, A TAPER RATIO OF 0.5, AND NACA 65A004 AIRFOIL SECTION

摘要

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 projec¬tion on the control effectiveness of spoiler-slot-deflectors on a 30° 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 wing. The wing had an aspect ratio of 3, a taper ratio of 0.5, and NACA 65AOOI+ airfoil section. The tests were made at angles of attack from -4° to 24° at a 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.
