Get this from a library. Experimental and computational aerothermodynamics of a Mars entry vehicle. [Brian R Hollis; United States. National Aeronautics and Space Administration.]. obtaining high-fidelity data for computational model development and validation for such phenomena has become one of the primary roles of wind tunnel testing, in addition to its customary role of producing data for vehicle design, development, and performance evaluation.

Therefore, the discipline of experimental aerothermodynamicsFile Size: 7MB. The Mars Science Laboratory (MSL) mission (Ref. 2), to be launched inwill deliver the largest (> kg) rover ever to Mars. The MSL vehicle (Figure 1) will fly a controlled, lifting trajectory (α = 16 deg) to deliver the payload to within 10 km of the target location.

The entry vehicle is comprised of a m diameter spherically. An experimental investigation of turbulent aeroheating on the Mars Science Laboratory entry vehicle heat shield has been conducted in the Arnold Engineering Development Center Hypervelocity Wind.

Analysis of Entry Vehicle Aerothermodynamics Using the Direct Simulation Monte Carlo Method accurately computed by using free molecular flow analysis.1 The properties of interest in entry vehicle analysis are those that affect the vehicle’s performance.

This book gives an introduction to the basics of aerothermodynamics, as applied in particular to winged re-entry vehicles and airbreathing cruise and acceleration vehicles.

Beginning with a broad vehicle classification and a discussion of the flight environment, Basics of Aero-thermodynamics focuses on flight in the earth's atmosphere at speeds.

The present research focuses on both Aerodynamics and Aerothermodynamics of a re-entry vehicle. The objective is to provide an optimized model in both respects by analyzing local properties like heat flux, pressure distribution and global parameters like mono stability and lift-drag characteristics by: 3.

This paper presents a literature survey on supersonic retropropulsion technology as it applies to Mars entry, descent, and landing (EDL). The relevance of this technology to the feasibility of Mars EDL is shown to increase with ballistic coefficient to the point that it is likely required for human Mars exploration.

Most of the current data are relative to mass flow rates and inlet/outlet pressures for channel flows, or to local temperature and pressure measurements at the wall by microsensors or sensitive paints, but there is a crucial need for investigating velocity and temperature fields directly within the gas in a rgdorg/ Afterbody Heating Predictions for a Mars Science Laboratory Entry Vehicle.
