Book Abort Separation Longitudinal Force and Moment Characteristics of McDonnell Douglas Booster and Orbiter Space Shuttle Vehicles at Mach Numbers 2 0 to 6 0

Download or read book Abort Separation Longitudinal Force and Moment Characteristics of McDonnell Douglas Booster and Orbiter Space Shuttle Vehicles at Mach Numbers 2 0 to 6 0 written by R. H. Burt and published by . This book was released on 1972 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are presented for abort staging wind tunnel tests which were conducted to determine the aerodynamic characteristics of the McDonnell Douglas booster and orbiter configurations in close proximity. Data were obtained on both scale models over an angle-of-attack range from -10 to +10 deg for zero slideslip angle. Orbiter incidence angle relative to the booster was varied from -10 to +10 deg which provided an orbiter angle-of-attack range from -20 to +20 deg. The models were tested at Mach numbers from 2.0 to 6.0 at several separation distances and power conditions. An annular cold-flow nozzle in each model was used to simulate booster and orbiter plumes at various altitudes along a proposed ascent trajectory. Plume simulation for 100, 50, and 0 percent of full power for the booster and 100, 50, 25, and 1 percent of full power for the orbiter was investigated, with 50-percent booster and 100-percent orbiter power as the nominal conditions. Pitch control effectiveness data were obtained for both booster and orbiter with power on and off. In addition, data were obtained with and without booster power simulation on a proposed launch configuration where the orbiter was physically attached to the booster, and a single balance in the booster model was utilized. A complete set of plotted data for each vehicle at each test condition is included. (Author).

Book Aerodynamic Characteristics of Several Hypersonic Boost glide type Configurations at Mach Numbers from 2 30 to 4 63

Download or read book Aerodynamic Characteristics of Several Hypersonic Boost glide type Configurations at Mach Numbers from 2 30 to 4 63 written by Ernald B. Graves and published by . This book was released on 1968 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been conducted at Mach numbers from 2.30 to 4.63 to determine the static aerodynamic characteristics of several configurations designed for flight at hypersonic Mach numbers. Two all-wing and three wing-body configurations were tested through an angle-of-attack range from about -4° to 33° and an angle-of-sideslip range from about -4° to 8° at a Reynolds number of 3 x 106 per foot (9.84 x 106 meter). The results of the investigation indicated that the wing-body configurations produced higher values of maximum lift-drag ratio than those produced by the all-wing models. The high-body configurations tend to have a self-trimming capability as opposed to that for the low wing-body configurations. Each of the configurations produced a positive dihedral effect that increased with increasing angle of attack and decreased with increasing Mach number. The high wing-body models produced decreasing values of directional stability with increase in angle of attack, whereas the low wing-body models provided increasing values of directional stability with increase in angle of attack.

Book Aerodynamic Characteristics and Control Effectiveness of the Hl 20 Lifting Body Configuration at Mach 10 in Air

Download or read book Aerodynamic Characteristics and Control Effectiveness of the Hl 20 Lifting Body Configuration at Mach 10 in Air written by National Aeronautics and Space Administration and published by . This book was released on 2018-08-27 with total page 60 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 2 deg to 41 deg, the sideslip angles were 0 deg, 2 deg, and -2 deg, and the test Reynolds number was 1.06 x 10 E6 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 deg. 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.Scallion, William I.Langley Research CenterAERODYNAMIC CHARACTERISTICS; CONTROLLABILITY; EFFECTIVENESS; LIFTING BODIES; SCALE MODELS; WIND TUNNEL TESTS; ELEVONS; FINS; YAWING MOMENTS; STABILITY; SIDESLIP; REYNOLDS NUMBER; LONGITUDINAL CONTROL; LATERAL CONTROL; HYPERSONIC SPEED; FLOW VISUALIZATION; FLAPPING; ANGLE OF ATTACK...
