Available in PDF, EPUB and Kindle. Book excerpt: This project aims to enable the reader to acquire the necessary knowledge to fully understand the main facts and working principles of modern wind tunnels and their application in F1. In addition one of the goals is to enable the reader to get an insight of the motorsport world, realizing how important aerodynamics are in relation to the global performance and handling of a race car. Throughout the entire project particular emphasis has been made to illustrate the importance of wind tunnels and how they are necessary even in teams or companies with powerful CFD systems. Despite the fast advances of IT technologies currently every part of high level motorsports aerodynamics cannot be understood without wind tunnels. Starting in an explanation about why the CFD simulation are still not developed enough to be able to be used as the sole aerodynamic design tool in the designing process of an F1 and explaining how CFD and wind tunnels complement each other the project is then divided into two different parts: Part I: The first part focuses in the theory and definitions behind wind tunnel and aerodynamic testing in general. In order to be able to understand the design and characteristics of wind tunnels it is first necessary to describe the aerodynamics principles and their relation to race car designs. All these explanations have been accompanied by real life examples and explained using data measured directly in real race cars. Everything related to wind tunnel testing has been described in this part. Starting from a description of all the different types of tunnels (classified according to different criteria). The main instrumentation required for wind tunnel testing has also been described in this section as well as the differences between scale-model and full size testing with the positive and negative points of each method. An exhaustive listing with the main facts of all the different F1 tunnel facilities has been included, paying special attention to the Epsilon Euskadi headquarters which include the best wind tunnel dedicated to motorsports in the Spanish territory and possibly one of the best worldwide. Together with the Toyota facilities in Germany, they were among the few that were intended to provide the rental of facilities per hour (as a way of self-financing, his topic is extensively dealt with in the economic part of the study). Part II: The second part includes different practical test and experimentations. Firstly based on real track data of a World Series by Renault 3.5 car, an exhaustive study of the DRS systems and its effects in car performance has been carried out. During all the data analysis references to F1 innovations and regulations are made to help the reader immerse into the racing world. In addition the necessary tools and equations necessary to determine the theoretical top speed of any car knowing their characteristics has also been described and applied to the same World Series race car. As mentioned before in this summary during all these sections of the project it has been a priority to give as much real racing information and data as possible trying to give the reader a real experience of the tools race and design engineers use. Without any hesitation the most important part test of the practical part focuses on the World series car rear-view mirrors being tested in different wind tunnel facilities. The aerodynamic study has been realized using different methodologies and tested in different tunnel types. This whole process is extensively detailed in order to enable the reader if desired to be able to carry this same tests (all the necessary tools and calculations included) Lastly, note that this project is not intended under any circumstances to provide numerical values that can be used in real applications as it focuses more on concepts and is intended to be a reference on wind tunnel experimental methodology rather than in the absolute results.

Lucas and published by . This book was released on 1979 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted in the Propulsion Wind Tunnel (16T) to determine the effect of throttle-dependent parameters (nozzle closure and nozzle pressure ratio) on the aft end surface pressures of a 0.2-scale model of a twin-engine fighter prototype (YF-17). The data are part of a data base to be used in a wind tunnel/flight correlation to define the validity of current wind tunnel test techniques to provide data for full-scale flight performance predictions. Surface pressure data were obtained on several model configurations, using a wingtip support system, to define the effects of nozzle closure and jet exhaust flow on the test article nacelle and nozzle surfaces. Two additional test entries were conducted on sting support systems to evaluate support system interference produced by the wingtip support system and to evaluate the annular-jet test technique.

Download or read book Small Scale Model Tests in Small Wind and Water Tunnels at High Incidence and Pitch Rates Volume 2 Small Wind Tunnel ADF Data Base written by Atlee M Cunningham (Jr) and published by . This book was released on 1989 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Force testing of small-scale models in either a small wind tunnel or a water tunnel was investigated as an inexpensive and quick means to obtain meaningful dynamic force and moment data representative of rapidly maneuvering full-scale aircraft. Force tests of flat-plate semi-span models were conducted in the General Dynamics Aerodynamic Development Facility (ADF) which is a small 14-in. x 14-in. low speed wind tunnel. Oscillatory model motions up to 48 deg (peak to peak) amplitude were tested at frequencies of 1 to 3 Hz. Force tests of flat and three-dimensional full span models were conducted in G.D.'s Hydroflow Facility (HFF) which is a horizontal flow water tunnel with a 24-in. x 24-in. test section. Pitch/pulse model motions were tested for conditions similar to those tested in the ADF. The test velocities were 100 fps in the ADF and 0.8 fps in the HFF which yielded nominal Reynolds numbers of 0.6 million and 0.06 million respectively (based on root chord). This volume presents the data base generated from tests in the ADF. The normal force, pitching moment and rolling moment data are in plotted and tabulated form for the straked wing, 55 deg and 70 deg delta wings and 70 deg/30 deg cranked wing semi-span models. Steady results along with unsteady results for two frequencies are included for the overall incidence range of 0 deg to 80 deg. Geometric data for the models are also given. Keywords: Aerodynamic forces, Unsteady flow, Vortices, Flat plate models, Wind tunnel tests. (EDC).

Available in PDF, EPUB and Kindle. Book excerpt: Models of airplanes are now widely used in wind tunnels to obtain results from which the performance and stability of the full scale airplanes are predicted. The wind tunnel model, however, does not have complete mechanical similarity to the full scale airplane. Part of the dissimilarity is due to the difference between the stationary model in the artificial wind stream of the tunnel and moveing airplane in still air, in that the former system can be brought into equilibrium by the application of forces and moments external to the model wind system while the latter system can not. As a consequence, the wind tunnel model may have any weight or centroid location consistent with the capacity of wind tunnel balance to bring it into equilibrium at the desired attitudes to the wind. Therefore the only similarity required between the full scale airplane and the model is geometric similarity or similarity of external form.
