| description abstract | INTRODUCTION Extensive research as indicated that airfoil thickness is of primary Importance in the performance f aircraft designed to operate the transonic and supersonic speed ranges. At the request of the National Advisory Committee for Aeronautic, a 4percent-thick wing is being incorporated In the Bell X-1 research airplane. The use of thin sections, in general, an accompanying change in aspect ratio or taper ratio, 8 or both from purely structural considerations. The present paper presents the results of an investigation to determine the effect, if any, that a change in wing thickness and an associated change in aspect ratio would have on the low-speed static stability and control characteristics of the Bell X-1 airplane. The investigation was made in the Langley 300 MPH 7-by 10-foot tunnel with a ¼-scale model of the Bell X-1 airplane equipped with a wing of aspect ratio 4, taper ratio 0.5, 0o sweepback of the 0.40 chord line, and a modified NACA 64A004 airfoil section. The wing had a slotted flap of about 0.50 semispan and an aileron of 0.30 semispan. | |
