Book Jet induced Effects

Download or read book Jet induced Effects written by Richard E. Kuhn and published by AIAA (American Institute of Aeronautics & Astronautics). This book was released on 2006 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unique characteristics of V/STOL flight bring with it unique aerodynamic challenges. Intended for the working professional or those in engineering graduate programs involved with V/STOL, this book provides information on the aerodynamic effects induced by the exiting flows of jet and fan powered V/STOL aircraft in hover and transition flight.

Book Prediction Techniques for Jet Induced Effects in Hover on Stovl Aircraft

Download or read book Prediction Techniques for Jet Induced Effects in Hover on Stovl Aircraft written by National Aeronautics and Space Adm Nasa and published by . This book was released on 2018-10-18 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prediction techniques for jet induced lift effects during hover are available, relatively easy to use, and produce adequate results for preliminary design work. Although deficiencies of the current method were found, it is still currently the best way to estimate jet induced lift effects short of using computational fluid dynamics. Its use is summarized. The new summarized method, represents the first step toward the use of surface pressure data in an empirical method, as opposed to just balance data in the current method, for calculating jet induced effects. Although the new method is currently limited to flat plate configurations having two circular jets of equal thrust, it has the potential of more accurately predicting jet induced effects including a means for estimating the pitching moment in hover. As this method was developed from a very limited amount of data, broader applications of the method require the inclusion of new data on additional configurations. However, within this small data base, the new method does a better job in predicting jet induced effects in hover than the current method. Wardwell, Douglas A. and Kuhn, Richard E.

Book Field of Flow about a Jet and Effect of Jets on Stability of Jet propelled Airplanes

Download or read book Field of Flow about a Jet and Effect of Jets on Stability of Jet propelled Airplanes written by Herbert S. Ribner and published by . This book was released on 1946 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical investigation was conducted on jet-induced flow deviation. Analysis is given of flow inclination induced outside cold and hot jets and jet deflection caused by angle of attack. Applications to computation of effects of jet on longitudinal stability and trim are explained. Effect of jet temperature on flow inclination was found small when thrust coefficient is used as criterion for similitude. The average jet-induced downwash over tail plane was obtained geometrically.

Book Jet Induced Ground Effects on a Parametric Flat Plate Model in Hover

Download or read book Jet Induced Ground Effects on a Parametric Flat Plate Model in Hover written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-25 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The jet-induced forces generated on short takeoff and vertical landing (STOVL) aircraft when in close proximity to the ground can have a significant effect on aircraft performance. Therefore, accurate predictions of these aerodynamic characteristics are highly desirable. Empirical procedures for estimating jet-induced forces during the vertical/short takeoff and landing (V/STOL) portions of the flight envelope are currently limited in accuracy. The jet-induced force data presented significantly add to the current STOVL configurations data base. Further development of empirical prediction methods for jet-induced forces, to provide more configuration diversity and improved overall accuracy, depends on the viability of this STOVL data base. The data base may also be used to validate computational fluid dynamics (CFD) analysis codes. The hover data obtained at the NASA Ames Jet Calibration and Hover Test (JCAHT) facility for a parametric flat-plate model is presented. The model tested was designed to allow variations in the planform aspect ratio, number of jets, nozzle shape, and jet location. There were 31 different planform/nozzle configurations tested. Each configuration had numerous pressure taps installed to measure the pressures on the undersurface of the model. All pressure data along with the balance jet-induced lift and pitching-moment increments are tabulated. For selected runs, pressure data are presented in the form of contour plots that show lines of constant pressure coefficient on the model undersurface. Nozzle-thrust calibrations and jet flow-pressure survey information are also provided. Wardwell, Douglas A. and Hange, Craig E. and Kuhn, Richard E. and Stewart, Vearl R.
