This book was released on 2018-06-29 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method for designing conceptual supersonic cruise aircraft to meet low sonic boom requirements is outlined and described. The aircraft design is guided through a systematic evolution from initial three view drawing to a final numerical model description, while the designer using the method controls the integration of low sonic boom, high supersonic aerodynamic efficiency, adequate low speed handling, and reasonable structure and materials technologies. Some experience in preliminary aircraft design and in the use of various analytical and numerical codes is required for integrating the volume and lift requirements throughout the design process.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For future civil supersonic aircraft to have the operational flexibility offered by current subsonic aircraft, some means of reducing their sonic boom to acceptable levels is required. An effective technique by which the sonic boom ground signal may be altered, and potentially minimized, is through careful shaping of external features of the aircraft. By considering the detailed aircraft shape using nonlinear flow solvers, accurate assessments of sonic boom can be made during multi-disciplinary conceptual design optimization. Such capability would enable the development of aircraft satisfying not only a requirement on low boom, but also on the range of constraints and mission goals necessary to produce a viable aircraft design. This work presents a multi-level framework for the conceptual design of low sonic boom aircraft. The development of a robust, automated tool using output-driven mesh adaptation enables accurate prediction of sonic boom. Results are validated with available experimental data for a variety of signal forms. An approach combining linear supersonic potential theory with atmospheric propagation and loudness prediction methods is used to generate low-boom near-field signals subject to lift and equivalent area constraints. This signal generator is then used to build a response surface fit that enables a conceptual-level design optimization to develop aircraft configurations with low boom. The imposition of a diverse range of multi-disciplinary design constraints ensures a viable aircraft. Once a satisfactory baseline is obtained, the design is transferred to the CFD domain, where an adjoint-driven inverse design approach is used to determine the detailed aircraft shape. This optimization seeks to match the near-field pressure target associated with the conceptual baseline design, subject to geometric constraints that ensure conceptual-level performance predictions are preserved. An aircraft design example is presented, demonstrating the application of this approach on a supersonic business jet.

Download or read book Commercial Supersonic Technology written by National Research Council and published by National Academies Press. This book was released on 2002-02-16 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-speed flight is a major technological challenge for both commercial and business aviation. As a first step in revitalizing efforts by the National Aeronautics and Space Administration (NASA) to achieve the technology objective of high-speed air travel, NASA requested the National Research Council (NRC) to conduct a study that would identify approaches for achieving breakthroughs in research and technology for commercial supersonic aircraft. Commercial Supersonic Technology documents the results of that effort. This report describes technical areas where ongoing work should be continued and new focused research initiated to enable operational deployment of an environmentally acceptable, economically viable commercial aircraft capable of sustained supersonic flight, including flight over land, at speeds up to approximately Mach 2 in the next 25 years or less.

This book was released on 2018-08-27 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ongoing human-response studies of sonic-boom noise indicated that a previous level of 1.0 psf might still be too annoying. This led to studies of a Supersonic Business Jet (SBJ), which might generate lower, more acceptable ground overpressures. To determine whether methods for designing a High Speed Civil Transport (HSCT) could be successfully applied, a SBJ concept was designed at the langley Research Center. It would cruise at Mach 2, carry 10 passengers for 4000 nautical miles, and generate a 0.50 psf or less on the ground under the flight path at start of cruise. Results indicated that a 10-passenger, low-boom SBJ design was just as technically demanding as a 300-passenger, low-boom HSCT design. In this report, the sources of these technical problems are identified, and ideas for addressing them are discussed.Mack, Robert J.Langley Research CenterSONIC BOOMS; SUPERSONIC TRANSPORTS; AIRCRAFT DESIGN; SUPERSONIC JET FLOW; CIVIL AVIATION; HUMAN REACTIONS; PASSENGERS...

Book excerpt: From December 1991 to June 1992, applied aerodynamic research support was given to the team working on Low Sonic Boom configurations in the RAC branch at NASA Ames Research Center. This team developed two different configurations: a conventional wing-tail and a canard wing, in an effort to reduce the overpressure of shock waves and the accompanying noise which are projected to the ground from supersonic civil transport aircraft. A generic description of this sensitive technology is given. Lee, Christopher A. Unspecified Center NASA-CR-197744, NAS 1.26:197744, MCAT-95-07 NCC2-617...
