Download or read book Technical Report Model Tests of Vortex Ring Parachute at the Princeton University 4 Ft X 5 Ft Ft Wind Tunnel written by David T. Barish and published by . This book was released on 1959 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind tunnel tests were conducted of a large number of configurations of the Vortex Ring Parachute. These produced data for evaluating the effects on performance of porosity, a new panel geometry, rigging variations, four pilot chute configurations, three swivels, a flare model, the wake of a large disk placed upstream, cyclic pitch control, and ground effect. Detailed data were obtained from the flow field behind the chute, by smoke tunnel studies and velocity surveys. In addition, the effect on performance of putting slits in a standard 40" pilot chute to provide rotation was measured.
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.
Download or read book Technical Report on Vortex Ring Parachute Wind Tunnel Tests at United Aircraft Corporation written by David T. Barish and published by . This book was released on 1959 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: The program consisted of testing of full scale parachutes in the 33 foot square settling section, and the measurement of the deployments of deceleration chutes in the 18 foot octagonal test section. Drag measurements on two versions of the Vortex Ring Chute 21.7 feet and 32.5 feet in diameter gave values of drag coefficient, more than 1.8 times that measured with a 28' diameter flat circular chute in the same test section. Correlations with small scale wind tunnel tests are also included. A large number of deployments of the 260" diameter drag chutes were conducted in the test section at speeds from 50 mph to 187 mph. Dynamic force measurements indicated rapid deployment, low shock factor and stable operation. A new pilot chute installation gave good deployment characteristics and stable operation.

Pepper and published by . This book was released on 1985 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: During 1984 a series of 12 drop tests was conducted at the US Army Yuma Proving Ground near Yuma, Arizona to develop a new system to recover a 2200-lb resupply container from high altitude. The parachute system consists of a 15-ft-dia ribbon parachute reefed for 10 s and a 73-ft-dia cross parachute with no reefing. The system has been successfully demonstrated by flight tests. The impact velocity is 30 fps.

Download or read book Results of Drop Tests of a 63 FT Para sail Gliding Parachute written by J. D. Reuter and published by . This book was released on 1966 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nine drop tests of a 63-ft-diameter Para-Sail gliding parachute were conducted at the Joint Parachute Test Facility, El Centro, California during the period from February through July, 1966. The canopy was tested with a 5000-lb suspended load, and was deployed at altitudes of 10,000 and 18,000 feet in both a horizontal and vertical flight path. A two-stage mid-gore reefing system was developed which limited opening loads to less than 20,000 pounds at 80 psf dynamic pressure. The parachute demonstrated a sea-level rate of descent of 29 ft/sec and a lift/drag ratio of 1.0. A description of the parachute system and sequence of events is presented for each test, together with reduced test data showing deployment conditions, parachute opening loads, and steady-stste performance.

Download or read book Flying beyond the stall written by Douglas A. Joyce and published by . This book was released on 2014 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The X-31 Enhanced Fighter Maneuverability Demonstrator was unique among experimental aircraft. A joint effort of the United States and Germany, the X-31 was the only X-plane to be designed, manufactured, and flight tested as an international collaboration. It was also the only X-plane to support two separate test programs conducted years apart, one administered largely by NASA and the other by the U.S. Navy, as well as the first X-plane ever to perform at the Paris Air Show. Flying Beyond the Stall begins by describing the government agencies and private-sector industries involved in the X-31 program, the genesis of the supermaneuverability concept and its initial design breakthroughs, design and fabrication of two test airframes, preparation for the X-31's first flight, and the first flights of Ship #1 and Ship #2. Subsequent chapters discuss envelope expansion, handling qualities (especially at high angles of attack), and flight with vectored thrust. The book then turns to the program's move to NASA's Dryden Flight Research Center and actual flight test data. Additional tasking, such as helmet-mounted display evaluations, handling quality studies, aerodynamic parameter estimation, and a "tailless" study are also discussed.The book describes how, in the aftermath of a disastrous accident with Ship #1 in 1995, Ship #2 was prepared for its outstanding participation in the Paris Air Show. The aircraft was then shipped back to Edwards AFB and put into storage until the late 1990s, when it was refurbished for participation in the U. S. Navy's VECTOR program. The book ends with a comprehensive discussion of lessons learned and includes an Appendix containing detailed information.
