Investigation of spoiler ailerons for use as speed brakes or glide-path controls on two NACA 65-series wings equipped with full-span slotted flaps /

Analysis indicates that this use of spoiler ailerons is feasible and desirable for normal emergency operatiion of airplanes. These speed brakes or glide-path controls would probably have small effect on wing pitching moments and should retain their rolling effectiveness.Ths report contains the results and discussion of an investigation of plug and retractable ailerons used as speed brakes or glide-path controls on an NACA 65-210 wing and an NACA 65₂-215 wing of aspect ratio 5.76 equipped with full-span slotted flaps. Incremental lift, drag, and pitching-moment data are presented for various flap conditions through a large-scale angle-or-attack range at Mach numbers from 0.13 to 0.71.NACA TN No. 1933."August 1949."Includes bibliographical references.Analysis indicates that this use of spoiler ailerons is feasible and desirable for normal emergency operatiion of airplanes.
