Recovery system design guide by E. G Ewing( Book )

6 editions published between 1978 and 1981 in English and held by 102 WorldCat member libraries worldwide

This document serves as the third revision of the USAF Parachute Handbook which was first published in 1951. The data and information represent the current state of the art relative to recovery system design and development. The initial chapters describe representative recovery applications, components, subsystems, material, manufacture and testing. The final chapters provide empirical data and analytical methods useful for predicting performance and presenting a definitive design of selected components into a reliable recovery system. (Author)

Feasibility study of a universal aerial recovery system by E. G Ewing( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

A study and analysis has been made of several combinations of parachutes and appendages in quest of a universally-adaptable parachute system concept, capable of aerial recovery and scalable over a weight range of 300 to 2000 pounds. The study included supplementing data on existing concepts, performing experimental specimen-testing of new approaches to existing concepts, and the testing of some new concepts to determine whether or not development of such a parachute system is feasible. Concepts investigated included the conical extension and "rabbit ear" concepts which the Air Force has been developing; a gliding parachute system, and airfoil (annular) system concept, and a modified ringsail incorporating a conical extension constructed in the ringsail tradition. Experimental tests have shown that deployment of such a universal parachute system is feasible and further testing has demonstrated the feasibility of aerial recovery of the annular concept
Demonstrated structural safety factors : Apollo Block I Earth Landing System by E. G Ewing( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

A series of 12 Boilerplate Parachute Subsystem tests was conducted at El Centro over an nine-month period ending in February 1966. Boilerplate vehicles simulating the Apollo Spacecraft Command Module were air dropped from a NAA/S & ID supplied modified Douglas C-133A aircraft at various conditions to simulate actual abort and entry missions. The parachute subsystem configuration was representative of spacecraft design. The test series was successful in demonstrating the ability of the system to meet requirements. Individual drop tests results as well as new performance requirements introduced during the test program prompted a series of design improvements, none of which significantly changed the basic design of the system. The series was primarily devoted to the aerodynamic and structural characteristics of the system, as a final supplement to more rigorously instrumented Northrop Ventura conducted environmental tests at lower system levels in the laboratory, NAA/NASA conducted rocket powered abort tests at White Sands Proving Grounds, and unmanned suborbital and orbital spacecraft flights
A minimum weight landing system for interplanetary spacecraft by E. G Ewing( Book )

1 edition published in 1960 in English and held by 1 WorldCat member library worldwide

The popular concept of a spacecraft landing, shared by scientist and layman alike, appears to derive form the TV "Space Opera". We are accustomed to the spectacle of a massive rocket-powered vehicle executing a gradual stern-first descent on its main jets to the surface of a planetary body. The engineer viewer may sense that this prodigal expenditure of propellant must proceed from some bottomless reservior not shown. Most of us, however, are becoming inured to the fantastic waste represented by this type of landing approach and may come to think of it as a necessary cost of interplanetary exploration. ... But ... when the destination has a significant atmosphere, a more ecpnomical landing method is in order. The landing system envisioned employs parachutes and retro-rockets. Although the actual landing operation will be less spectacular than the spacerocket landing portrayed in fiction, its rapidity and austerity may be harder for the layman to accept as a safe and sane procedure. As will be seen shortly, in every such landing operation, it will appear to all ordinary senses that the vehicle has descended safely on its parachute only to crash in flames
Ringsail parachute design by E. G Ewing( Book )

2 editions published in 1972 in English and held by 1 WorldCat member library worldwide

This document is intended for use as a design handbook for the Ringsail parachute. It begins with an historical review of the aerodynamic and structural development of the parachute, including the development of the modified Ringsail design used in the Apollo ELS main parachute cluster. Salient characteristics of all Ringsail parachutes fabricated and tested over the past 16 years are summarized. An exposition of the present status of Ringsail design and operational theory, with special emphasis on a general theory of the inflation characteristics of clustered canopies, is given
