INTRODUCTION

As part of the wind-tunnel program required for the development of the North

American X-15 research airplane, a 0.0667-scale force model of the final version

of the X-15 (configuration )) has.been tested in the Langley 8-f'00t transonic

pressure tunnel in order to determine its static stability and control character-

istics at transonic speeds. Tests of this model at Mach numbers from 2.29 to 4.65

are reported in reference L The results of pressure-distribution tests of a

model of a configuration nearly identical to that of configuration ) at Mach num-

bers from 0.60 to 4.65 are presented in references 2 and). Other tests of force

models approximating configuration) are reported in references 4 to 7. Tests of

a force model of an earlier version of the X-15 (configuration 1) in the Langley

8-foot transonic pressure tunnel are reported in reference 8.

The model was tested at Mach numbers from 0.60 to 1.18, at angles of attack

0 0 0

from -20 to 20 , and at angles of sideslip of -5.1 and 0 • Drag, static lon-

gitudinal stability, and static lateral-directional stability were determined;

the effectiveness of the horizontal tail as a pitch and roll control and the

vertical tails as a yaw control was measured; and the effects of opening the

speed brakes on drag and static stability were obtained. The results of this

investigation including a summary of some of the important stability and control parameters are presented herein without analysis.

It employs a 5-percent-thick low-aspect-ratio trapezoidal wing mounted in the midposition on a fuselage consisting of a body of revolution with large side fairings. The horizontal tail which has 45 sweep- back of the quarter-chord line is all movable for pitch control and is deflected differentially for roll control. The outboard panels of the upper and lower vertical-tail surfaces are deflected for directional control; the inboard panels are fixed and contain the speed brakes.

The 0.0667-scale force model of the North American X-15 research airplane used in this investigation was supplied by the contractor and was of stainless- steel construction. Photographs of the model are presented in figure 1, and dimensional details are shown in figure 2 and table I.

The model represented configuration 3 of the X-15. Features that distin-

guish this configuration from configuration 1 (ref. 8) include an increased

fuselage diameter, shortened fuselage side fairings, increased leading-edge radii on wing and horizontal tail, wing shifted forward 3~6 inches (full scale), horizontal tail shifted rearward 5.4 inches (full scale), a larger vertical tail having 10 full-wedge airfoil sections with the total exposed area distributed

about 55 percent above the fuselage and 45 percent below, and reduced speed-

brake area. The contractor's code designation for the model tested was

B4W2X14H9VU5JU2VL7JL2'

The movable portions of the upper and lower vertical tails and both

horizontal-tail panels could be actuated remotely while the wind tunnel was in

operation. The speed brakes were maintained in the closed position or were

opened 35 relative to the closed position as indicated in figure 2. The speed-

brake hinge lines were located at the speed-brake leading edges and had 0

sweepback.

Tunnel and Model Support

The tests were conducted in the Langley 8-foot transonic pressure tunnel

which is a single-return rectangular slotted-throat wind tunnel having controls

that allowed for the independent variation of Mach number, stagnation pressure, temperature, and humidity.

The model was attached to a sting support by an electrical strain-gage bal-

ance located inside the fuselage. The sting support was cylindrical for 2.4 base

diameters downstream of the model base and had a diameter of 0.55 base diameter.

At its downstream end, the sting was attached to an arc-shaped support strut

which spanned the tunnel vertically. This support strut was rotated to obtain

changes in angle of attack; the center of rotation of the system was near the

model in order to minimize overall vertical motion of the model. Variations in

angle of sideslip were obtained by insertion of properly angled couplings in the

model support system.

Measurements and Accuracy

Model forces and moments were measured by a six-component internal strain-

gage balance. They were converted by automatic electrical computing equipment

to lift, drag, and pitching moment about the stability axes and to lateral force,

yawing moment, and rolling moment about the body axes. (See fig. 3.) The center

of gravity was located at 20 percent of the meav aerodynamic chord based on the

total wing area. (See fig. 2.) At a Mach number of 1.0 and a dynamic pressure

of 784 pounds per square foot, accuracies of the coefficients are estimated to

be:

C . . • • . . . . .

y The angle of attack was set to within ±O.lo by means of a pendulum-type attitude indicator located in the nose of the model. The angles of sideslip were determined to within ±0.2° by means of a calibration of sting and balance deflection with respect to model lateral force and yawing moment. Horizontal- and vertical-tail deflections were measured remotely by means of differential transformers attached to the control-surface linkages and are estimated to be accurate within ±0.2°. Speed-brake deflections are estimated to be accurate within ±O.lo.

The Mach number was determined within ±0.003 from a calibration with respect to the pressure in the chamber surrounding the slotted test section.

Base pressure coefficients were determined from an average of measurements taken on the upper and lower portions of the base and are estimated to be accurate within ±0.005.

Tests The complete model was tested with horizontal-tail deflections for pitch and roll control, with vertical-tail deflections for yaw control, and with the speed brakes open and closed. The model was also tested with the horizontal tail removed, with the lower vertical tail removed, and with both vertical tails removed. The detailed test program is indicated in table II.

The test range included Mach numbers from 0.60 to 1.18, angles of attack 0 0 from _20 to 20°, and angles of sideslip of -5.1 and 0 • The tests were con- ducted at a tunnel stagnation pressure of approximately 1 atmosphere. The average test Reynolds number based on the wing mean aerodynamic chord varied from approximately 2.2 X 10 to 2.8 X 10 over the Mach number range. (See

fig. 4.) For all tests, O.l-inch.,;wide boundary-layer transition strips con-

sisting of No. 120 carborundum grains were installed along the 10-percent-chord lines of the wing and tail surfaces and at 10 percent of the fuselage length.

Corrections Tuni.l.el-boundary interference at subsonic speeds is minimized by the slotted test section, and no corrections for this interference have been applied. No corrections are necessary for the effects of supersonic boundary-reflected dis- turbances since they are negligible for Mach numbers up to approximately 1.03

(ref. 9), and the reflected disturbances pass well downstream of the base of

the model at a Mach number of 1.18.

With the use of the measured base pressure coefficients (shown for thI:'ee con- figurations in fig. 5), the data presented have been adjusted to an assumed con- dition of free-stream static pressure acting over the base of the fuselage. No sting-interference corrections have been applied. However, as indicated from the results of reference 10, errors in the drag data due to the presence of the sting,are estimated to be small and errors in the other coefficients are prob- ably negligible.

RESULTS AND CONCLUSIONS The results of an investigation of the stability and control characteristics of a 0.0667-scale model of the final version of the X-15 research airplane are presented in the following figures: Figures . . . . . . . .

The data indicate that the configuration investigated has generally satis- factory static stability and control characteristics at the Mach numbers and angles of attack tested. Notable exceptions, however, include a region of neutral longitudinal stability at low negative angles of attack at Mach numbers from 0.60 to 0.95 and excessive positive dihedral at high angles of attack at Mach numbers above 0.60.
