This book was released on 1954 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Choked operation of model jets with unheated air indicates the appearence of a discrete-frequency component of very large magnitude. Shadowgraph records of the flow show that this condtion is associated with the appearance of flow formations suggestive of partly formed toroidal vortices in the vicinity of the shocks. Elimination of these formations is found to eliminate the discrete component and thereby to reduce the overall noise level.
Download or read book Component Acoustic Testing Plane Wave Tube and Reverberant Chamber Methods written by Charles W. Remaley and published by . This book was released on 1958 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design features and operating parameters of plane wave tube and reverberant chambers are described. Four different size plane wave tubes are used with a driving power of 200 audio watts to achieve sound pressure levels up to 154 db between 300 and 7500 cps. Two reverberant chambers are described and their performance evaluated. A comparison is made of the merits of plane wave sound fields and reverberant sound fields for testing purposes.

Download or read book Hovering Flight Tests of a Four engine transport Vertical Take off Airplane Model Utilizing a Large Flap and Extensible Vanes for Redirecting the Propeller Slipstream written by Louis P. Tosti and published by . This book was released on 1955 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of the take-off, landing, and hovering-flight characteristics of a four-engine-transport, vertical take-off airplane has been conducted with a remotely controlled free-flight model. The model had four propellers distributed along the wing with thrust axes parallel to the fuselage axis. In order to produce direct lift for hovering flight, the propeller slipstream was deflected downward about 70 degrees by a full-span 65-percent-chord flap deflected 90 degrees and eight extensible vanes arranged above the wing in a cascade relation.
Download or read book Recent Advances in Aerodynamics written by Anjaneyulu Krothapalli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Joint Institute for Aeronautics and Acoustics at Stanford University was established in October 1973 to provide an academic environment for long-term cooperative research between Stanford and NASA Ames Research Center. Since its establishment, the In stitute has wnducted theoretical and experimental work in the areas of aerodynamics, acoustics, fluid mechanics, flight dynamics, guid ance and control, and human factors. This research has involved Stanford faculty, research associates, graduate students, and many distinguished visitors in collaborative efforts with the research staff of NASA Ames Research Center. The occasion of the Institute's tenth anniversary was used to reflect back on where that research has brought us, and to consider where our endeavors should be directed next. Thus, an International Symposium was held to review recent advances in the fields relevant to the activities of the Institute and to discuss the areas of research to be undertaken in the future. This anniversary was also chosen a.."1 an opportunity to honor one of the Institute's founders and its di rector, Professor Krishnamurty Karamcheti. It has been his creative inspiration that has provided the ideal research environment at the Joint Institute. The International Symposium on Recent Advances in Aero dynamics and Aconstics was held at Stanford University, Stanford, California, U.S.A., August 22-26, 198:~. Thirty-five distinguished scientists were invited to present a comprehensive review on the fol lowing subject areas: unsteady aerodynamics, jets and shear layers, V /STOL aircraft aerodynamics, rotor dynamics and aerodynamics,.
