Book excerpt: "The purposes of this document are (1) to provide an overview of the calibration of subsonic and transonic wind tunnels and (2) to provide a basis for commonality within the wind tunnel community in the area of wind tunnel calibration. Various standards have been developed over the years in the aeronautics industry, many of which pertain to ground testing. These standards have made it easier to share information and hardware, and have allowed the community to improve its overall effectiveness. This document, however, is not intended to set standards for wind tunnel calibration. Details of calibrating a wind tunnel vary from facility to facility according to the type of tests conducted, the operating envelope of the tunnel, and the physical constraints of the facility, which makes having a rigid definition of calibration procedures inappropriate. Instead, this document provides a set of recommended practices that the reader can use to develop a complete tunnel calibration program."--Executive summary, p. 1.

Available in PDF, EPUB and Kindle. Book excerpt: A cooperative effort between the Office National d'Etudes et de Recherches Aerospatiales (ONERA); the National Aeronautic and Space Administration, Ames Research Center (NASA-ARC); and the Arnold Engineering Development Center (AEDC) was accomplished whereby two ONERA standard calibration models (M3 and M5) and an area equivalent body of revolution (C5) were tested in the NASA-ARC 11-ft and the AEDC 16-ft and 4-ft transonic wind tunnels. The tests were designed to provide an experimental data base for (1) the evaluation of theoretical or empirical wall-interference correction factors and (2) the establishment of guidelines to allow reasonable selection of wind tunnel to model size ratios in the transonic speed regime. The results showed that large effects of Reynolds number, tunnel flow quality, and small difference in model geometry preclude a determination of wall interference from the M3 and M5 model data. The primary cause of the data differences is a variation in the wing shock/separation patterns between the three tunnel tests. Even though the model forces may, in certain instances, agree from tunnel to tunnel, pressure distributions showed the agreement to be fortuituous. The C5 model data indicated subsonic theory underpredicts the required blockage correction by a factor of two to ten and, because the blockage interference effect changes sign along the model, simply correcting the Mach number will not compensate for the transonic interference.

Download or read book Calibration of the AEDC-PWT 16-ft Transonic Tunnel at Test Section Wall Porosities of Two, Four, and Six Percent written by F. M. Jackson and published by . This book was released on 1976 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted in the AEDC Propulsion Wind Tunnel (16T) to determine the centerline Mach number distributions and the tunnel calibration at test section wall porosities of two, four, and six percent. The calibration was conducted over the Mach number range from 0.2 to 1.6. A quantitative evaluation of the effects of Mach number, tunnel pressure ratio, test section wall angle, and test section wall porosity upon the centerline Mach number distributions was determined by analysis of the local Mach number deviations. Limited data were also obtained to provide an indication of the effect of Reynolds number upon the calibration. The results indicate that Mach number distributions of good flow quality are obtained at porosities of two, four, and six percent for test section wall angles which vary from 0 to 0.50 deg. Variation of test section wall porosity, as well as wall angle, significantly affects the Tunnel 16T calibration. Comparison of this calibration with a previous calibration, however, indicates that no new tunnel calibration is required for operation at a porosity of six percent with either a zero or optimum wall angle schedule.

This book was released on 1978 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted in the AEDC Propulsion Wind Tunnel (16T) to determine the tunnel test section Mach number distributions and calibration at various Reynolds numbers. The calibration was conducted at Mach numbers from 0.2 to 1.6 and at Reynolds numbers from 400,000/ft to 6,400,000/ft. The calibration was conducted using the propulsion test section (Test Section 1) and centerline pipe and wall pressure orifices to define the Mach number distributions. A quantitative evaluation of the effects of tunnel pressure ratio, test section wall angle, and Reynolds number on the centerline Mach number distributions was determined by analysis of the local Mach number deviations. The results indicate that Mach number distributions of good quality are obtained for both zero and the optimum wall angle schedule. For complete generality, the Tunnel 16T calibration must be defined as a function of test section wall angle, Reynolds number, and Mach number.

This book was released on 1981 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: A test was conducted in the Propulsion Wind Tunnel (16T) to: (1) define the effect of plenum suction utilization on the tunnel calibration and power consumption at free-stream Mach numbers less than 0.75, (2) improve the centerline Mach number calibration at supersonic Mach numbers, (3) correlate the test section centerline Mach number with the tunnel nozzle Mach number, and (4) investigate the effect of tunnel humidity on the calibration. Data were acquired for Mach numbers from 0.6 to 1.6 at total pressures from 400 to 3,200 psfa. The calibration was conducted in the aerodynamic test section using a centerline pipe and wall pressure orifices to define the Mach number distributions. The results of an evaluation of alternate methods of calibration indicated that the current method is the most acceptable. Slightly changing the tunnel nozzle to eliminate the disturbances in the flow at supersonic Mach numbers indicated the need to investigate the entire nozzle system. Comparison of this calibration with previous calibration results indicates that a revision of the current tunnel calibration is not necessary. (Author).

This book was released on 2018-11-13 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the results of a study which was conducted in order to establish a framework for the quantitative description of the uncertainty in measurements conducted in the National Transonic Facility (NTF). The importance of uncertainty analysis in both experiment planning and reporting results has grown significantly in the past few years. Various methodologies have been proposed and the engineering community appears to be 'converging' on certain accepted practices. The practical application of these methods to the complex wind tunnel testing environment at the NASA Langley Research Center was based upon terminology and methods established in the American National Standards Institute (ANSI) and the American Society of Mechanical Engineers (ASME) standards. The report overviews this methodology. Batill, Stephen M.
