Book excerpt: 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 projection on the control effectiveness of spoiler-slot-deflectors on a 30 degree 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 ring. The wing had an aspect ratio of 3, a taper ratio of 0.5, and NACA 65A004 airfoil section. The tests were made at angles of attack from -4 to 24 degrees at 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.

This book was released on 1950 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: A free-flight-tunnel investigation has been made to compare the dynamic lateral control characteristics provided by step plug ailerons on a sweptback-wing model having full-span flaps. The model had a 38 degree sweptback wing with an aspect ratio of 3 and a taper ratio of 0.05. The static stability and control characteristics of the flight-test model were determined from force tests and the time-lag characteristics of the ailerons were determined from stand tests in which there was freedom only in roll. Flight tests of the model were made over a range of lift coefficient from 1.0 through the stall.

Book excerpt: This paper presents the results of an investigation to determine the control-effectiveness characteristics of 30-percent-chord flap-type control surfaces of various spans on a semispan wing-fuselage model. The wing of the mode had 35 degrees of sweepback of the quarter chord, an aspect ratio of 4.0, a taper ratio of 0.6, and an NACA 65A006 airfoil section parallel to the free stream. Lift, rolling moments, and pitching moments were obtained for several angle of attack throughout a small range of control-surface deflections. Most of the data are presented as control-effectiveness parameters which show their variation with Mach number.

West and published by . This book was released on 1956 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted in the Langley 16-foot transonic tunnel to determine the characteristics of several flap-type spoiler ailerons, lower-surface deflector ailerons, and spoiler-slot-deflector ailerons. These controls were located in the vicinity of the 70-percent wing chord line and extended outboard to 87 percent of the wing semispan. The flap-type spoilers were tested at only one projection. The wing of the wing-body combination used in these tests had 45 degree sweepback, an aspect ratio of 4.0, a taper ratio of 0.60, and NACA 65A006 airfoil sections parallel to the plane of symmetry. Six-component force and moment data were obtained at Mach numbers from 0.60 to 1.03 (Reynolds numbers from 5,050,000 to 6,000,000) for an angle-of-attack range from 0 to approximately 20 degrees.

This book was released on 1950 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been conducted to compare the dynamic lateral control characteristics provided by step plug ailerons with those provided by conventional flap ailerons on a sweptback-wing model. The model used had a 38c sweptback wing with an aspect ratio of 3 and a taper ratio of O.5. The static stability and control characteristics of the flight test model were determined from force tests and the lag characteristics of the ailerons were determined from roll-free stand tests. Flight tests of the model were made through a range of lift coefficient from 0.6 through the stall by using the data obtained from the force tests to establish the flight test conditions. At each lift coefficient in the flight test range the flap ailerons were adjusted to produce the same static rolling moment as was obtained by maximum projection of the plug ailerons. The controllability of the model was more satisfactory with plug ailerons alone than with flap ailerons alone except at lift coefficients below about 0.7. At the lower lift coefficients the time lag from full control deflection to maximum rolling acceleration caused by the plug ailerons was more objectionable than the slight adverse yawing caused by the flap ailerons; whereas, at the higher lift coefficients, the loss of rolling effectiveness caused by the large adverse yawing moments of the flap ailerons was more objectionable than the lag of the plug ailerons. At the stall, the model could be controlled satisfactorily with the plug ailerons alone or with the flap ailerons and rudder but could not be controlled satisfactorily with the flap ailerons alone.

This book was released on 1950 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made in the Langley full-scale tunnel of the low-speed lateral characteristics of a 47.5 degree swept-back-wing - fuselage combination with several flap and spoiler aileron arrangements at a Reynolds number of 4,400,000. The wing had an aspect ratio of 0.51, and NACA 64(1)A112 airfoil sections. The results indicated that the rolling effectiveness of small-span ailerons located inboard of the wing tips were greater than the effectiveness of equal-span ailerons located at the wing tips. At lift coefficients near the stall, the aileron effectiveness of the model with thick trailing-edge contour ailerons was essentially the same as the aileron effectiveness of the original contour ailerons.

Naeseth and published by . This book was released on 1954 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A low-speed wind-tunnel investigation was made to determine the static lateral control characteristics of flap-type and retractable spoiler-type ailerons on a rigid sweptback wing, a flexible sweptback wing, and a flexible M-wing. A few tests were also made with a half-delta tip control on the flexible sweptback wing. The semispan wing models were of aspect ratio 6.0, taper ratio of 0.6, and had NACA 65A009 airfoil sections parallel to the free-stream direction. The quarter-chord lines of the wings were swept 45 degrees and the break in the M-wing was at the half semispan location.
