This book was released on 1971 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: A reefed B.2-meter nominal-diameter (40-ft) disk-gap-band parachute was flight tested as part of the NASA Supersonic High Altitude Parachute Experiment (SHAPE) program. A three-stage rocket was used to drive an instrumented test payload to an altitude of 43.6 km (143 000 ft) and a Mach number of 2.58 where the parachute was deployed by means of a mortar. After a time delay of about 8.5 seconds, the parachute was disreefed at a Mach number of 0.99. The report contains an analysis of parachute inflation, drag, and stability for both the reefed and unreefed parts of the test. In addition, detailed descriptions of the test parachute, the reefing system, and the parachute packing procedurea are included.

Book Synopsis High-altitude Flight Test of a 40-foot-diameter (12.2-meter) Ringsail Parachute at a Deployment Mach Number of 2.95 by : Clinton V. Eckstrom
Download or read book High-altitude Flight Test of a 40-foot-diameter (12.2-meter) Ringsail Parachute at a Deployment Mach Number of 2.95 written by Clinton V. Eckstrom and published by . This book was released on 1970 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 40-foot-nominal-diameter (12.2-meter) modified ringsail parachute was flight tested as part of the NASA Supersonic High Altitude Parachute Experiment (SHAPE) program. The 41-pound (18.6-kg) test parachute system was deployed from a 239.5-pound (108.6-kg) instrumented payload by means of a deployment mortar when the payload was at a Mach number of 2.95 and a free-stream dynamic pressure of 9.2 lb/sq ft (440 N/m2). The parachute deployed properly with the canopy inflating to a near full open condition followed immediately by a partial collapse of the canopy and subsequent oscillations of the frontal area until the system had decelerated to a Mach number of about 1.5. The parachute then attained an inflated shape that provided full drag area. During the supersonic part of the test, the average axial-force coefficient C A, 0 varied from a minimum of about 0.24 at a Mach number of 2.7 to a maximum of 0.54 at a Mach number of 1.1. During descent under subsonic conditions, the average effective drag coefficient was 0.62 and parachute-payload oscillation angles averaged about ±10° with excursions to ±20°.--P. [i].

This book was released on 1967 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inflation, drag, and stability characteristics of an 85.3-foot (26 meter) nominal diameter ringsail parachute deployed at a Mach number of 1.15 and at an altitude of 132,600 feet (40.42 kilometers) were obtained from the first flight test of the Planetary Entry Parachute Program. After deployment, the parachute inflated to the reefed condition. However, the canopy was unstable and produced low drag in the reefed condition. [remainder of summary illegible].
Book Synopsis Inflation and Performance of Three Parachute Configurations from Supersonic Flight Tests in a Low-density Environment by : Charles H. Whitlock
Download or read book Inflation and Performance of Three Parachute Configurations from Supersonic Flight Tests in a Low-density Environment written by Charles H. Whitlock and published by . This book was released on 1969 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten flight tests of modified-ringsail, disk-gap-band, and cross parachute configurations with deployment at Mach numbers and dynamic pressures corresponding to conditions expected during entry into a Martian atmosphere have been completed. Comparison of flight results indicates that theoretical snatch force values were never exceeded when the deployment techniques of these tests were used. Opening loads showed no definite trend with Mach number. Values for filling times compared favorably with generally accepted empirical curves based on 15-percent geometric porosity. Canopy stability was good when Mach numbers were below 1.4 for the modified-ringsail and disk-gap-band configurations.

Book Synopsis Wind-tunnel Tests of Modified Cross, Hemisflo, and Disk-gap-band Parachutes with Emphasis in the Transonic Range by : James T. Foughner
Download or read book Wind-tunnel Tests of Modified Cross, Hemisflo, and Disk-gap-band Parachutes with Emphasis in the Transonic Range written by James T. Foughner and published by . This book was released on 1974 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transonic wind-tunnel studies were conducted with modified cross, hemisflo, and disk-gap-band parachute models in the wake of a cone-cylinder shape forebody. The basic cross design was modified with the addition of a circumferential constraining band at the lower edge of the canopy panels. The tests covered a Mach number range of 0.3 to 1.2 and a dynamic pressure range from 479 Newtons per square meter to 5746 Newtons per square meter. The parachute models were flexible textile-type structures and were tethered to a rigid forebody with a single flexible riser. Different size models of the modified cross and disk-gap-band canopies were tested to evaluate scale effects. Model reference diameters were 0.30, 0.61, and 1.07 meters (1.0, 2.0, and 3.5 ft) for the modified cross; and nominal diameters of 0.25 and 0.52 meter (0.83 and 1.7 ft) for the disk-gap-band; and 0.55 meter (1.8 ft) for the hemisflo. Reefing information is presented for the 0.61-meter-diameter cross and the 0.52-meter-diameter disk-gap-band. Results are presented in the form of the variation of steady-state average drag coefficient with Mach number. General stability characteristics of each parachute are discussed. Included are comments on canopy coning, spinning, and fluttering motions.
