Download or read book The Effects of Design Parameters and Local Flow Fields on the Performance of Hyperflo Supersonic Parachutes and High Dynamic Pressure Parachute Concepts written by Leland W. Sims and published by . This book was released on 1965 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wake flow field surveys were conducted in the wind tunnel behind several side strut mounted forebodies in the Mach number range from 2 to 5. Studies of the effects of design parameters on Hyperflo supersonic parachutes, and of high dynamic pressure parachute configurations deployed in such wakes were performed. Wake pressure distributions indicated an asymmetry due to the forebody support structure, and a disturbance to the flow field which emanates from the support structure. The latter was most pronounced at Mach numbers above 3. Modification to the wake caused by an air bleed into the forebody base was also indicated. Normal, but higher than predicted axial wake Mach number distributions were found to exist in the forebody wakes. Hyperflo tests at Mach numbers 5 to 5.5 showed abnormally large parachute oscillations with models located at large downstream positions aft of the forebodies. The effects of Hyperflo design parameters and forebody type on model performance are only qualitatively indicated by the tests conducted. (Author).

Download or read book Drag and Stability Characteristics of a Variety of Reefed and Unreefed Parachute Configurations at Mach 1.80 with an Empirical Correlation for Supersonic Mach Numbers written by Lana M. Couch and published by . This book was released on 1975 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted at Mach 1.80 in the Langley 4-foot supersonic pressure tunnel to determine the effects of variation in reefing ratio and geometric porosity on the drag and stability characteristics of four basic canopy types deployed in the wake of a cone-cylinder forebody. The basic designs included cross, hemisflo, disk-gap-band, and extended-skirt canopies; however, modular cross and standard flat canopies and a ballute were also investigated. An empirical correlation was determined which provides a fair estimation of the drag coefficients in transonic and supersonic flow for parachutes of specific geometric porosity and reefing ratio.

Download or read book Parachute Recovery Systems written by Theo W. Knacke and published by . This book was released on 1992 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to provide recovery system engineers in government and industry with tools to evaluate, analyze, select, and design parachute recovery systems. These systems range from simple, one-parachute assemblies to multiple-parachute systems, and may include equipment for impact attenuation, flotation, location, retrieval, and disposition. All system aspects are discussed, including the need for parachute recovery, the selection of the most suitable recovery system concept, concept analysis, parachute performance, force and stress analysis, material selection, parachute assembly and component design, and manufacturing. Experienced recovery system engineers will find this publication useful as a technical reference book; recent college graduates will find it useful as a textbook for learning about parachutes and parachute recovery systems; and technicians with extensive practical experience will find it useful as an engineering textbook that includes a chapter on parachute- related aerodynamics. In this manual, emphasis is placed on aiding government employees in evaluating and supervising the design and application of parachute systems. The parachute recovery system uses aerodynamic drag to decelerate people and equipment moving in air from a higher velocity to a lower velocity and to a safe landing. This lower velocity is known as rate of descent, landing velocity, or impact velocity, and is determined by the following requirements: (1) landing personnel uninjured and ready for action, (2) landing equipment and air vehicles undamaged and ready for use or refurbishment, and (3) impacting ordnance at a preselected angle and velocity.
