This book was released on 1968 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the analysis of the means of measuring the force and stability characteristics of flexible, steerable, gliding parachutes in the AFFDL 12-foot open-throat vertical wind tunnel at Wright-Patterson Air Force Base, a system was designed, fabricated, installed, and tested for acceptance. This system consists of two major components: The first major component, a test fixture-balance assembly, provides the means of remotely operating model parachutes through various roll, pitch, and yaw angles. This assembly consists basically of a roll-traversing mechanism which supports a sting balance as it rolls and yaws along the inner perimeter of a semicircular trussed hoop. The hoop rests on a two-part structure designed for temporary installment above the tunnel lip. For the parachute attachment and positioning, the sting balance was selected in a preliminary study in preference to the wire or strut type of balance. The second major component, a data acquisition and readout system, displays and records in digital form the normal and axial forces and the moments at various canopy pitch, roll, and yaw attitudes. In the acceptance tests with a 9.375-foot steerable parachute canopy, lift, drag, and pitching moment were obtained at various angles of pitch and at air velocities ranging from 50 to 100 feet per second.
Book Synopsis Computerized Video Instrumentation Technique for Wind Tunnel Testing of Parachutes by : R. H. Croll
Download or read book Computerized Video Instrumentation Technique for Wind Tunnel Testing of Parachutes written by R. H. Croll and published by . This book was released on 1981 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind tunnel testing of parachute systems requires that correlated motion and load data be obtained simultaneously on both the forebody and the parachute to define the aerodynamic performance of this two-body system. The flexible nature of parachutes and the need for timely reduced data dictated the use of a computerized video instrumentation technique to support full-scale wind tunnel testing of lifting parachutes. Characteristics and capabilities of this versatile instrumentation and data acquisition/processing system are discussed.

This book was released on 2018-08-16 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data has been acquired for a rotocraft test in the NASA Langley Transonic Dynamics Tunnel using a desktop data acquisition system. The system, which consists of an IBM Personal Computer AT (PC-AT) and an Omega Engineering OM-900 Stand-Alone Interface System, is well suited for acquiring high speed data on a limited number of channels. The data acquisition system and the interrupt driven software which provides the capability for near real-time cyclic data acquisition as well as data storage and display are described.

Download or read book Manual for Operation and Maintenance of Parachute Test Instrumentation written by Joseph F. Braun and published by . This book was released on 1962 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The system described in this manual is designed specifically for usage in the Vertical Wind Tunnel. The system contains instrumentation capable of recording parachute test data while the parachutes are fixed in a given position by a mechnanical structure. The hardware furnished with the unit makes it possible to conduct such tests with as many as seven parachutes in a cluster. The mechanical structure is adjustable so that the parachutes can be properly separated by a simple adjustment.

Download or read book Wind Tunnel Tests to Evaluate a Lifting Transonic Parachute written by R. E. Rychnovsky and published by . This book was released on 1975 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: A program to develop a two-step lifting parachute system for low altitude payload delivery at velocities up to Mach 1.2 is being conducted at Sandia Laboratories. Wind tunnel tests on scaled models have been used extensively in the development. The test objectives were to establish the feasibility of constructing a lifting parachute with the desired characteristics, to select the most promising design and construction technique from several candidate models, to optimize the performance of this model and to measure its aerodynamic coefficients. A description of the types of tests, the models and test hardware as well as pertinent results and future test plans are presented.
