This book was released on 1963 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of flutter model tests in the supersonic Mach number range of 1.5 to 3.0 on a series of representative high-speed models are presented. Cantilever model data and free-flight model data were obtained. The free-flight model data were obtained from a new method of testing. The method obtains free-flight flutter information from restrained models in the wind tunnel through use of mechanical admittance measurements. (Author).

Download or read book Wind Tunnels and Experimental Fluid Dynamics Research written by Jorge Colman Lerner and published by IntechOpen. This book was released on 2011-07-27 with total page 726 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book "Wind Tunnels and Experimental Fluid Dynamics Research" is comprised of 33 chapters divided in five sections. The first 12 chapters discuss wind tunnel facilities and experiments in incompressible flow, while the next seven chapters deal with building dynamics, flow control and fluid mechanics. Third section of the book is dedicated to chapters discussing aerodynamic field measurements and real full scale analysis (chapters 20-22). Chapters in the last two sections deal with turbulent structure analysis (chapters 23-25) and wind tunnels in compressible flow (chapters 26-33). Contributions from a large number of international experts make this publication a highly valuable resource in wind tunnels and fluid dynamics field of research.

This book was released on 1975 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: A research study was conducted to develop active flutter suppression wind tunnel testing technology. A one-thirtieth scale B-52 aeroelastic model was modified to represent the Control Configured Vehicles (CCV) B-52 flight test airplane with an active flutter mode control system (FMCS). The system was mechanized on the model using electromechanical actuation systems for the scaled CCV airplane outboard aileron and flaperon outboard segment control surfaces. The model was tested in the NASA-Langley Transonic Dynamics Tunnel to evaluate the unaugmented model flutter characteristics and performance of the flutter mode control system. Test results were compared with model analytical results and CCV program flight test results for equivalent weight and altitude conditions. The model flutter speed, in airplane scale, is 8.1 percent higher than the airplane flutter speed, less than 1.0 percent higher than the predicted difference. Flutter mode damping with the FMCS engaged is higher on the model than on the airplane, but the damping trends with increasing airspeed are similar. The good agreement attained between model and airplane test results demonstrates that dynamically scaled models can be used to verify analytical methods used to design active flutter mode control systems.

This book was released on 2018-06-19 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flutter of an aeroelastic structure is potentially destructive aeroelastic instability. This phenomenon has motivated research within the aeroelastic community to develop methods that can accurately predict aeroelastic instabilities. The Flutterometer method used herein, and as developed by NASA DFRC, is based upon the mu method which has been coupled with wavelet filtering processes in estimating aeroelastic models from flight data. The approach leads to a methodology to predict the occurrence of flutter boundaries, and may prove to reliably predict flutter boundaries during flight tests. An analytical model is used as the first estimate of the aeroelastic structural dynamics, and uncertainty operators are introduced into the system to model variations between the theoretical system and the physical system. The modelling uncertainties are then updated from experimental data. Although the model used did not work well with this particular experiment, a sensitivity analysis was additionally performed and improvements suggested. Strganac, Thomas W.
