Book Aircraft Configurations Developing High Lift drag Ratios at High Supersonic Speeds

Download or read book Aircraft Configurations Developing High Lift drag Ratios at High Supersonic Speeds written by A. J. Eggers (Jr.) and published by . This book was released on 1956 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: The problem of designing an aircraft which will develop high lift-drag ratios in flight at high supersonic speeds is attacked using the elementary principle that the components of the aircraft should be individually and collectively arranged to impart the maximum downward and the minimum forward momentum to the surrounding air. This principle in conjunction with other practical considerations of hypersonic flight leads to the study of configurations for which the body is situated entirely below the wing; that is, flat-top wing-body combinations. Theory indicates that sensibly complete aircraft of this type can be designed to develop lift-drag ratios well in excess of 6.

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 Some Aerodynamic Characteristics of Supersonic Lifting Bodies

Download or read book Some Aerodynamic Characteristics of Supersonic Lifting Bodies written by Charles J. Nietubicz and published by . This book was released on 1975 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerodynamic characteristics are presented for various lifting body configurations. Data were collected for an angle of attack sweep of -10 degrees to +10 degrees throughout a Mach number range of 1.5 to 4.0. The test Reynolds number per meter was 15,700,000. The data are presented as standard force coefficients which have additionally been transformed about a tunnel axis coordinate system to obtain lift and drag data. The normal force center of pressure was found to be invariant with angle of attack and Mach number for all configurations.
