Abstract
A wind-tunnel investigation has been m a d e a t low speed i n t h e Langley 300 MPH 7by 10-foot tunnel to determine t h e effect of deflector project i o n on t h e control effectiveness of spoiler-slot-deflectors on a 30° swep5back wing-fuselage m o d e l equipped w i t h e i t h e r a 15-percent-chord s p o i l e r or a spoiler-slot-deflector t h a t extended from t h e 20-t o t h e 99-percent-semispan s t a t i o n of t h e r i g h t wing.The wing had m aspect r a t i o of 3 , a t a p e r r a t i o of 0.5, and NACA 65~0oh.a i r f o i l s e c t i o n .The tests were made a t angles of a t t a c k from A0 t o 2 4 O a t a Mach number " -
