Low-speed investigation of the lateral-control characteristics of a flap-type spoiler and a spoiler-slot deflector on a 30 degrees sweptback wing-fuselage model having an aspect ratio of 3, a taper ratio of 0.5, and NACA 65A004 airfoil section

description abstractINTRODUCTION
Recent investigations of spoiler-type controls suitable for use on high-speed thin-wing configurations have shown that the spoiler-slot-deflector has certain advantages over the plain flap-type spoiler, such as lower hinge moments and more effectiveness at high angles of attack. (For example, see ref. 1. )
One of the variables to be considered in the design of a spoiler-slot-deflector is the ratio of the projection of the deflector to that of the spoiler. In order to, determine the variation of the lateral-control characteristics of a spoiler-slot-deflector with deflector projection at a given spoiler projection, an investigation has been made in the Langley 300 MPH 7- by 10-foot tunnel on a 30° sweptback wing-fuselage model. The right wing of the model was equipped with a 17-percent-wing-chord spoiler, slot, and deflector extending from 0.20b/2 to 0.99b/2, enabling tests to be made on a plain spoiler and a spoiler-slot-deflector configuration at various control projections.
A pressure-distribution investigation performed in the Langley 300 MPH 7- by 10-foot tunnel on this model for which pressure measurements were made at 6 spanwise stations on the wing and at 5 spanwise stations on the spoiler and deflector on the model of this investigation is reported in reference 2.
The discussion of the results of the data of this investigation will be confined to the effect of deflector projection on the rolling effectiveness of the spoiler-slot-deflector.
