This book was released on 2020-08-21 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of cavities (for attachment bolts) on the heat-shield of the proposed Mars Science Laboratory entry vehicle has been investigated experimentally and computationally in order to develop a criterion for assessing whether the boundary layer becomes turbulent downstream of the cavity. Wind tunnel tests were conducted on the 70-deg sphere-cone vehicle geometry with various cavity sizes and locations in order to assess their influence on convective heating and boundary layer transition. Heat-transfer coefficients and boundary-layer states (laminar, transitional, or turbulent) were determined using global phosphor thermography. Hollis, Brian R. and Liechty, Derek S.

This book was released on 2018-08-09 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: In high speed flight, the state of the boundary layer can strongly influence the design of vehicles through its effect on skin friction drag and aerodynamic heating. The major mechanisms causing boundary layer transition on high speed vehicles are briefly reviewed and some empirical relations from the unclassified literature are given for the transition Reynolds numbers.

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.

Download or read book Heat-Transfer Tests on a 14-Percent-Scale Model of the NASA-MMC Viking Mars Entry Vehicle at Mach Number 16 written by and published by . This book was released on 1973 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Viking Mars Lander vehicle is to be protected during the Martian entry by a 70-deg half-angle, spherically blunted, conical heat shield designated as the aeroshell. The aeroshell surface contains several surface features (protuberances and cavities) associated with mechanical fittings and entry instrumentation. Heat-transfer rates in the vicinity of such features are known to be significantly affected, with local heat-transfer-rate amplification being dependent on the feature geometry and the flow environment. The test program described was initiated to verify the adequacy of the design criteria for the aeroshell and base cover heat shields.
