This book was released on 2000 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a method that can calculate transient aerodynamic heating and transient surface temperatures at supersonic and hypersonic speeds. This method can rapidly calculate temperature and heating rate time-histories for complete flight trajectories. Semi-empirical theories are used to calculate laminar and turbulent heat transfer coefficients and a procedure for estimating boundary-layer transition is included. Results from this method are compared with flight data from the X-15 research vehicle, YF-12 airplane, and the Space Shuttle Orbiter. These comparisons show that the calculated values are in good agreement with the measured flight data.

This book was released on 1979 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of complex lifting configurations and high speed maneuvering vehicles has emphasized the need for numerical techniques to predict aerodynamic heating rates as a function of the vehicle trajectory. These numerical programs are not expected to eliminate the requirements for wind tunnel and flight testing, but will be an aid to more efficient use of experimentation time and improve confidence that all potential problem areas on the vehicle have been examined. Three programs, the Hypersonic Arbitrary Body Program, the MINIVER Program, and a third program were examined to determine their usefulness for vehicles with non-circular cross sections and large flat areas as exemplified by lifting reentry vehicles. The MINIVER code was found to be unsuitable for this; the Hypersonic Arbitrary Body Program was applicable to these shapes, but because of program limitations was used for only limited calculations. The last program also had limitations in the areas of geometry description and surface pressure calculations. Efforts were made to remove these limitations and several shapes were investigated. The ultimate goal of this effort was to extend the capabilities of one or more of the heating codes; while no effort was made to improve MINIVER or the Hypersonic Arbitrary Body Program, significant improvements were made in the last program and inviscid flow field program.

This book was released on 1973 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heat transfer rates using calorimeter sensors, and pressures using variable reluctance diaphragm transducers, have been measured on five model shapes at Mach numbers of 15 and 20 and over a unit Reynolds number range of 2 million to 7 million per foot. Two basic shapes, a hemisphere and a half-angle biconic configuration with and without nose bluntness, were tested with different surface roughness. The results are reported and discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Aerodynamic lift is used during re-entry to provide range maneuverability so that a precise site can be selected and a horizontal landing capability can be provided. Maximum maneuverability may be achieved by modulating the hypersonic lift-to drag ratio (L/D). In this study the lifting re entry configuration was optimized to maximize hypersonic L/D within the heating, stability, and landing constraints. Eleven pertinent constraint equations were formulated, and numerical calcula tions of the complete aerodynamic characteristics and configurational geometry were determined. The IBM 7090 computer was used to solve the 11 constraint equations through an iteration tech nique and to perform the maximization process. Optimum configurational geometries were evaluated for three wing loadings at vehicle weights of 10,000 and 100,000 pounds. Results show that higher L/D values can be achieved with low aspect ratio, low wing loadings, and large scale vehi cles. The complete geometry for one of the typical optimums is shown as an example.
