This book was released on 2019-01-13 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted in support of the Orbiter damage assessment activity that takes place for each Shuttle mission since STS-107 (STS - Space Transportation System). As part of the damage assessment activity, the state of boundary layer (laminar or turbulent) during reentry needs to be estimated in order to define the aerothermal environment on the Orbiter. Premature turbulence on the wing leading edge (WLE) is possible if a surface irregularity promotes early transition and the resulting turbulent wedge flow contaminates the WLE flow. The objective of this analysis is to develop a criterion to determine if and when the flow along the WLE experiences turbulent heating given an incoming turbulent boundary layer that contaminates the attachment line. The data to be analyzed were all obtained as part of the MH-13 Space Shuttle Orbiter Aerothermodynamic Test conducted on a 1.8%-scale Orbiter model at Calspan/University of Buffalo Research Center in the Large Energy National Shock Tunnels facility. A rational framework was used to develop a means to assess the state of the WLE flow on the Orbiter during reentry given a contaminated attachment-line flow. Evidence of turbulent flow on the WLE has been recently documented for a few STS missions during the Orbiter s flight history, albeit late in the reentry trajectory. The criterion developed herein will be compared to these flight results. King, Rudolph A. and Vaughan, Matthew P. Langley Research Center NASA/TM-2009-215949, L-19784, LF99-9713

Book Synopsis Thermostructural Evaluation of Joggle Region on the Shuttle Orbiter's Wing Leading Edge by : National Aeronautics and Space Adm Nasa
Download or read book Thermostructural Evaluation of Joggle Region on the Shuttle Orbiter's Wing Leading Edge written by National Aeronautics and Space Adm Nasa and published by Independently Published. This book was released on 2019-01-14 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was initiated to determine the cause of coating spallation occurring on the Shuttle Orbiter's wing leading edge panels in the slip-side joggle region. The coating spallation events were observed, post flight, on differing panels on different missions. As part of the investigation, the high re-entry heating occurring on the joggles was considered here as a possible cause. Thus, a thermostructural evaluation was conducted to determine the detailed state-of-stress in the joggle region during re-entry and the feasibility of a laboratory test on a local joggle specimen to replicate this state-of-stress. A detailed three-dimensional finite element model of a panel slip-side joggle region was developed. Parametric and sensitivity studies revealed significant stresses occur in the joggle during peak heating. A critical interlaminar normal stress concentration was predicted in the substrate at the coating interface and was confined to the curved joggle region. Specifically, the high interlaminar normal stress is identified to be the cause for the occurrence of failure in the form of local subsurface material separation occurring in the slip-side joggle. The predicted critical stresses are coincident with material separations that had been observed with microscopy in joggle specimens obtained from flight panels. Walker, Sandra P. and Warren, Jerry E.

Ticatch and published by . This book was released on 1983 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were performed on scale models of the Space Shuttle Orbiter at angles of attack from 25 to 40 degrees at Mach 8 and 10. Thin-film instrumentation and testing techniques were used to provide aero-heating measurements on the wing leading edge. Standard techniques were adapted to obtain body flap heating measurements over a range of flap angles (0-20 deg) using a continuous sweep testing mode for various boundary layer transition locations. Pitot pressure probing was conducted in the vicinity of the wing leading edge and vapor screen photographs were obtained at various stations along the entire length of the orbiter body. Only sample tabulations of the test results are included in this documentary report. (Author).

Book Synopsis Version 2 of the Protuberance Correlations for the Shuttle-Orbiter Boundary Layer Transition Tool by : National Aeronautics and Space Administration (NASA)
Download or read book Version 2 of the Protuberance Correlations for the Shuttle-Orbiter Boundary Layer Transition Tool written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-05-29 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Orbiter-specific transition data, acquired in four ground-based facilities (LaRC 20-Inch Mach 6 Air Tunnel, LaRC 31-Inch Mach 10 Air Tunnel, LaRC 20-Inch Mach 6 CF4 Tunnel, and CUBRC LENS-I Shock Tunnel) with three wind tunnel model scales (0.75, 0.90, and 1.8%) and from Orbiter historical flight data, have been analyzed to improve a pre-existing engineering tool for reentry transition prediction on the windward side of the Orbiter. Boundary layer transition (BLT) engineering correlations for transition induced by isolated protuberances are presented using a laminar Navier-Stokes (N-S) database to provide the relevant boundary-layer properties. It is demonstrated that the earlier version of the BLT correlation that had been developed using parameters derived from an engineering boundary-layer code has improved data collapse when developed with the N-S database. Of the new correlations examined, the proposed correlation 5, based on boundary-layer edge and wall properties, was found to provide the best overall correlation metrics when the entire database is employed. The second independent correlation (proposed correlation 7) selected is based on properties within the boundary layer at the protuberance height. The Aeroheating Panel selected a process to derive the recommended coefficients for Version 2 of the BLT Tool. The assumptions and limitations of the recommended protuberance BLT Tool V.2 are presented. King, Rudolph A. and Kegerise, Michael A. and Berry, Scott A.
