Book Synopsis High-altitude Flight Test of a Reefed 12.2-meter-diameter Disk-gap-band Parachute with Deployment at a Mach Number of 2.58 by : John S. Preisser
Download or read book High-altitude Flight Test of a Reefed 12.2-meter-diameter Disk-gap-band Parachute with Deployment at a Mach Number of 2.58 written by John S. Preisser and published by . 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 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 Investigation of Inflation of Disk-gap-band and Modified Ringsail Parachutes at Dynamic Pressures Between 0.24 and 7.07 Pounds Per Square Foot by : Charles H. Whitlock
Download or read book Wind-tunnel Investigation of Inflation of Disk-gap-band and Modified Ringsail Parachutes at Dynamic Pressures Between 0.24 and 7.07 Pounds Per Square Foot written by Charles H. Whitlock and published by . This book was released on 1969 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploratory wind-tunnel tests of the disk-gap-band and modified ringsail parachute configurations have been conducted at dynamic pressures between 0.24 and 7.07 lb/ft2 (11 and 339 N/m2). Both parachutes exhibited positive inflation characteristics over the range of the tests within technique limitations. The disk-gap-band configuration required less time and distance to inflate than the modified ringsail configuration did.

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.

Book Synopsis Drag Characteristics of a Disk-gap-band Parachute with a Nominal Diameter of 1.65 Meters at Mach Numbers from 2.0 to 3.0 by : Robert J. Mayhue
Download or read book Drag Characteristics of a Disk-gap-band Parachute with a Nominal Diameter of 1.65 Meters at Mach Numbers from 2.0 to 3.0 written by Robert J. Mayhue and published by . This book was released on 1972 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supersonic wind-tunnel tests were conducted with disk-gap-band parachute models having a nominal diameter of 1.65 meters and geometric porosities of 10.0, 12.5, and 15.0 percent. Canopy inflation characteristics, angles of attack, and drag performance are presented for deployment behind forebody base extensions which were free to oscillate in pitch and yaw. The effect of increasing suspension-line length on canopy motions and drag performance is included, and the drag performance of a model with 12.5 percent geometric porosity is compared with results from flight tests of a parachute with a nominal diameter of 12.19 meters.
