This book was released on 1965 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: For some considerable time, experience has been accumulated on the retardation of military aircraft on landing by means of a brake parachute ... In considering the possible application to civil jet liners, three aspects will be discussed: (i) What are the advantages of a brake parachute in aircraft performance compared with reverse thrust devices. (ii) What effort may be needed to improve the reliability to an acceptable degree for use in civil aircraft. (iii) What are the special operating problems involved in using a brake parachute with civil, as distinct from military, aircraft and to what extent can these problems be overcome.

Available in PDF, EPUB and Kindle. Book excerpt: "Available literature on ram-air parachutes generally describe either experimental studies or the development of specific systems. Little fundamental analysis has been attempted. This Report reviews current knowledge and, where appropriate, formulates a theoretical basis for ram-air parachute design. Theoretical analysis fo inflation is found to be intractable due to the complication of reefing devices. A theoretical model for glide performance is developed from wing theory. Predictions compare favourably with experiment. Improvements in aerodynamic efficiency with increasing aspect ratio are largely negated by increased line drag. Optimum aspect ratio and line length and the potential for glide performance improvement are discussed. The effects of lift/draf ratio, wing laoding, control deflection, and wind, on rate of descent an dhorizontal velocity are demonstrated. Glide and control effectiveness are strongly influenced by rigging. A dynamic stability model is presented. Longitudinal control, flare and gust response are investigated. Stability is shown to increase with increasing altitutde, store mass and line length."--Summary, page 1.

This book was released on 2018-12-13 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Powered Parachute Flying Handbook is designed as a technical manual for applicants who are preparing for a powered parachute category rating and for currently certificated powered parachute pilots who wish to improve their knowledge. Certificated flight instructors will find this handbook a valuable training aid, since detailed coverage of emergency procedures, components and systems, aerodynamics, powerplants, ground operations, flight maneuvers, airport operations, and aeronautical decision making is included. Topics, such as navigation and communication, use of flight information publications, and regulations are available in other Federal Aviation Administration (FAA) publications.This handbook conforms to pilot training and certification concepts established by the FAA. There are different ways of teaching, as well as performing flight procedures and maneuvers, and many variations in the explanations of aerodynamic theories and principles. This handbook adopts a selective method and concept of flying powered parachutes. The discussion and explanations reflect the most commonly used practices and principles. Occasionally the word "must" or similar language is used where the desired action is deemed critical. The use of such language is not intended to add to, interpret, or relieve a duty imposed by Title 14 of the Code of Federal Regulations (14 CFR).

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 A Philosophical Basis for the Use of High performance Gliding Parachutes in Ejection Seat Aircraft written by Manley C. Butler and published by . This book was released on 1985 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents evidence and arguments for the use of ram-air inflated, gliding parachute wings in ejection seat aircraft. The advantages of the parachute are presented, along with numerous performance charts showing the effects of glide and wind on impact energy, impact velocity and angle, potential landing area and potential range. Performance data gathered in the Aircrew Gliding Escape System (AGES) Program are presented and contrasted with similar data from competing parachute systems. The analysis shows that the ram-air inflated gliding parachute wing is the most promising parachute available in the near future and offers significant benefits in safety and performance over the 28-foot diameter, flat circular parachute.

This book was released on 1959 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The text of the aerodynamics study and analysis shows the theoretical development of performance equations for airplanes trailing drag parachutes. Insofar as is possible, the development is made general. Where generality is best presented by study of specific airplanes, four aircraft as specified in Exhibit MCREXE-6B-33 are used to typify all current classes of aircraft. The installation proposals show the general application of various size parachutes to each class of aircraft as pertaining to basic flight maneuvers. The simplest parachute installations and operating systems are exemplified which would provide maximum utilization of the airplanes. It is concluded that it is possible and practical to install and operate the correct size parachute for aircraft deceleration both for in-flight maneuvers and ground roll deceleration. Additional study, development, design and in-flight testing are indicated.

Download or read book Aerodynamic Characteristics of the Parafoil Glider and Other Gliding Parachutes written by Helmut G. Heinrich and published by . This book was released on 1964 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: A newly conceived gliding parachute, called the parafoil glider, and several existing glide parachutes have been examined with regard to their general stability, resulting stable angle of attack, and lift to drag ratio. The parafoil glider assumed stable angles of attack up to 50 degrees against the vertical which represents a lift to drag ratio of approximately 1.2. The investigated existing parachutes had lift to drag ratios of less than unity. The tangential force coefficient of the parafoil glider amounts to approximately 1.5 at the position of the stable angle of attack.
