This book was released on 2018-07-04 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The requirements are assessed for the use of remote computation to support HRV flight testing. First, remote computational requirements were developed to support functions that will eventually be performed onboard operational vehicles of this type. These functions which either cannot be performed onboard in the time frame of initial HRV flight test programs because the technology of airborne computers will not be sufficiently advanced to support the computational loads required, or it is not desirable to perform the functions onboard in the flight test program for other reasons. Second, remote computational support either required or highly desirable to conduct flight testing itself was addressed. The use is proposed of an Automated Flight Management System which is described in conceptual detail. Third, autonomous operations is discussed and finally, unmanned operations.

This book was released on 1998-09-05 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was undertaken in response to a request by the U.S. Air Force that the National Research Council (NRC) examine whether the technologies that underlie the concept of a hypersonic, air-launched, air-breathing, hydrocarbon-fueled missile with speeds up to Mach 81 can be demonstrated in time to be initially operational by 2015. To conduct the study, the NRC appointed the Committee on Review and Evaluation of the Air Force Hypersonic Technology Program, under the auspices of the Air Force Science and Technology Board.

Download or read book Hypersonic Flight Testing written by and published by . This book was released on 1994 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The challenges of hypersonic system development require a combination of integrated ground testing, flight testing, and computational/simulation approaches. This report addresses the role of flight testing in the triad of development approach and is sub-divided into three parts: Propulsion, Aerothermal and Extrapolation of ground test data to flight. The reasons for propulsion flight test are illustrated by specific mini-case studies. The second part reviews some of the fundamental issues of flight testing and provides an overview of the aerothermal techniques. Specific examples include heat-transfer gage measurements and some of the common problems that have been encountered. The third part of this report discusses the initial flights of the Space Shuttle which uncovered a number of differences between preflight aerodynamic predictions and actual flight data. Most notable among these discrepancies was for longitudinal trim during high-speed re-entry. To investigate these differences, several computer codes were applied to a modified Space Shuttle Orbiter to determine aerodynamic parameters over a wide range of conditions. Computations were carried out for wind tunnel conditions and flight conditions to assess Mach number, real gas, and viscous effects on the reentry aerodynamics of the orbiter. flight-testing, Aerothermal techniques, Hypersonic vehicles, Computational Fluid Dynamics (CFD) simulations, High-speed re-entry.

This book was released on 2018-07-27 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the activities, results, conclusions and recommendations of the Magnetohydrodynamics Accelerator Research Into Advanced Hypersonics (MARIAH) Project in which the use of magnetohydrodynamics (MHD) technology is investigated for its applicability to augment hypersonic wind tunnels. The long range objective of this investigation is to advance the development of ground test facilities to support the development of hypervelocity flight vehicles. The MHD accelerator adds kinetic energy directly to the wind tunnel working fluid, thereby increasing its Mach number to hypervelocity levels. Several techniques for MHD augmentation, as well as other physical characteristics of the process are studied to enhance the overall performance of hypersonic wind tunnel design. Specific recommendations are presented to improve the effectiveness of ground test facilities. The work contained herein builds on nearly four decades of research and experimentation by the aeronautics ground test and evaluation community, both foreign and domestic.

Download or read book Hypersonic Flight Vehicles Perspective and Prognosis written by and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although hypersonics has been with us for over 50 years, the great advantages of very high speed flight have not been brought to engineering fruition. The present paper gives a brief overview of hypersonic flight, including the often neglected chemical reactions and upper atmospheric characteristics which MUST be included for realistic studies. The lack of ground test facilities with COMPLETE simulation of hypersonic flight is, in the author's view, a major impediment to ever developing, in some rational way, hypersonic vehicles with very high performance. There has been little facility research since the early 1970's and NO continuing effort to examine possible solutions because of the long lead time required to research and test such techniques. At the same time, current and future systems, which might take advantage of a very high speed flight regime, are severely handicapped by long lead times (beyond the project plans), and the expense of funding the research and development needed. Long lead times and expensive test set-ups are required to evaluate ANY hypersonic facility proposal, but flight test development is even more costly and time consuming. Modern computational capability and new knowledge bases in several key areas have been developed (briefly reviewed in the report) BUT, detailed testing is needed to validate concepts and preliminary designs. If we can't build a ground test facility, I suggest we can't build a vehicleZ.
