This book was released on 2018-07-17 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation was conducted in the Calspan 8-Ft Transonic wind tunnel at Mach numbers from 0.6 to 1.2. The 0.07-scale model had a low aspect ratio body with a flat undersurface. A center fin and two tip fins were mounted on the aft upper body. The tip fins were rolled outboard 40 deg from the vertical. Elevon surfaces made up the trailing edges of the outboard fins and body flaps were located on the upper and lower aft fuselage. Results of the investigation indicated that the model was longitudinally and laterally stable about a center-of-gravity position of 0.54 body length. The maximum trimmed lift-drag ratio was about 3.1 at M = 0.6. The small center fin contributed only a small positive increment to lateral stability but was effective as a yaw control device. Protuberances on the forebody had little effect on the aerodynamic characteristics of the configuration. The model with pitch controls undeflected had desirable longitudinal trim characteristics.

This book was released on 1999 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 0.0196-scale model of the HL-20 lifting body, one of several configurations proposed for future crewed spacecraft, was tested in the Langley 31-Inch Mach 10 Tunnel. The purpose of the tests was to determine the effectiveness of fin-mounted elevons, a lower surface flush-mounted body flap, and a flush-mounted yaw controller at hypersonic speeds. The nominal angle-of-attack range, representative of hypersonic entry, was 20 to 41 degrees, the sideslip angles were 0, 2, and -2 degrees, and the test Reynolds number was 1.06 x 10[factor 6] based on model reference length. The aerodynamic, longitudinal, and lateral control effectiveness along with surface oil flow visualizations are presented and discussed. The configuration was longitudinally and laterally stable at the nominal center of gravity. The primary longitudinal control, the fin-mounted elevons, could not trim the model to the desired entry angle of attack of 30 degrees. The lower surface body flaps were effective for roll control and the associated adverse yawing moment was eliminated by skewing the body flap hinge lines. A yaw controller, flush-mounted on the lower surface, was also effective, and the associated small rolling moment was favorable.

This book was released on 2018-07-16 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted in the Langley Unitary Plan Wind Tunnel at Mach numbers from 1.6 to 4.5. The model had a low-aspect-ratio body with a flat undersurface. A center fin and two outboard fins were mounted on the aft portion of the upper body. The outboard fins were rolled outboard 40 deg from the vertical. Elevon surfaces made up the trailing edges of the outboard fins, and body flaps were located on the upper and lower aft fuselage. The center fin pivoted about its midchord for yaw control. The model was longitudinally stable about the design center-of-gravity position at 54 percent of the body length. The configuration with undeflected longitudinal controls trimmed near 0 deg angle of attack at Mach numbers from 1.6 to 3.0 where lift and lift-drag ratio were negative. Longitudinal trim was near the maximum lift-drag ratio (1.4) at Mach 4.5. The model was directionally stable over Mach number range except at angles of attack around 4 deg at M = 2.5. Pitch control deflection of more than -10 deg with either elevons or body flaps is needed to trim the model to angles of attack at which lift becomes positive. With increased control deflection, the lifting-body configuration should perform the assured crew return mission through the supersonic speed range. Ware, George M. Langley Research Center...
