This book was released on 2018-08-27 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental evidence exists which suggests turbulent boundary layer relaminarization may play an important role in the inverse Reynolds number effect in high-lift systems. An experimental investigation of turbulent boundary layer relaminarization has been undertaken at the University of Notre Dame's Hessert Center for Aerospace Research in cooperation with NASA Dryden Flight Research Center. A wind tunnel facility has been constructed at the Hessert Center and relaminarization achieved. Preliminary evidence suggests the current predictive tools available are inadequate at determining the onset of relaminarization. In addition, an in-flight relaminarization experiment for the NASA Dryden FTF-II has been designed to explore relaminarization at Mach and Reynolds numbers more typical of commercial high-lift systems.Bourassa, Corey and Thomas, Flint O. and Nelson, Robert C.Armstrong Flight Research CenterMACH NUMBER; REYNOLDS NUMBER; TURBULENT BOUNDARY LAYER; WIND TUNNELS; PREDICTIONS; EXPERIMENTATION...

Download or read book Aerospace Engineering Education During the First Century of Flight written by Barnes Warnock McCormick and published by AIAA. This book was released on 2004 with total page 938 pages. Available in PDF, EPUB and Kindle. Book excerpt: On 17 December 1903 at Kitty Hawk, NC, the Wright brothers succeeded in achieving controlled flight in a heavier-than-air machine. This feat was accomplished by them only after meticulous experiments and a study of the work of others before them like Sir George Cayley, Otto Lilienthal, and Samuel Langley. The first evidence of the academic community becoming interested in human flight is found in 1883 when Professor J. J. Montgomery of Santa Clara College conducted a series of glider tests. Seven years later, in 1890, Octave Chanute presented a number of lectures to students of Sibley College, Cornell University entitled Aerial Navigation. This book is a collection of papers solicited from U. S. universities or institutions with a history of programs in Aerospace/Aeronautical engineering. There are 69 institutions covered in the 71 chapters. This collection of papers represents an authoritative story of the development of educational programs in the nation that were devoted to human flight. Most of these programs are still in existence but there are a few papers covering the history of programs that are no longer in operation. documented in Part I as well as the rapid expansion of educational programs relating to aeronautical engineering that took place in the 1940s. Part II is devoted to the four schools that were pioneers in establishing formal programs. Part III describes the activities of the Guggenheim Foundation that spurred much of the development of programs in aeronautical engineering. Part IV covers the 48 colleges and universities that were formally established in the mid-1930s to the present. The military institutions are grouped together in the Part V; and Part VI presents the histories of those programs that evolved from proprietary institutions.

Download or read book Key Topics for High Lift Research written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-05 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Future high-lift systems must achieve improved aerodynamic performance with simpler designs that involve fewer elements and reduced maintenance costs. To expeditiously achieve this, reliable CFD design tools are required. The development of useful CFD-based design tools for high lift systems requires increased attention to unresolved flow physics issues. The complex flow field over any multi-element airfoil may be broken down into certain generic component flows which are termed high-lift building block flows. In this report a broad spectrum of key flow field physics issues relevant to the design of improved high lift systems are considered. It is demonstrated that in-flight experiments utilizing the NASA Dryden Flight Test Fixture (which is essentially an instrumented ventral fin) carried on an F-15B support aircraft can provide a novel and cost effective method by which both Reynolds and Mach number effects associated with specific high lift building block flows can be investigated. These in-flight high lift building block flow experiments are most effective when performed in conjunction with coordinated ground based wind tunnel experiments in low speed facilities. For illustrative purposes three specific examples of in-flight high lift building block flow experiments capable of yielding a high payoff are described. The report concludes with a description of a joint wind tunnel/flight test approach to high lift aerodynamics research. Fisher, David and Thomas, Flint O. and Nelson, Robert C.

Download or read book David Vizard s Chevy Big Blocks written by David Vizard and published by CarTech Inc. This book was released on 2015-02-16 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chevy big-block has been installed in millions of cars and trucks over the past 50 years, including Camaros, Chevelles, Corvettes, Impalas, and a multitude of trucks. Extracting maximum performance has been the pursuit of engine builders ever since this engine was new in 1964. As a follow-up title to his How to Build Max-Performance Chevy Big-Blocks on a Budget, master engine builder David Vizard takes big-block Chevy engine building to the next level and shows how to build these extreme high-performance engines without breaking the bank. It goes well beyond the basic performance techniques and delves into exceptional detail on each component group of the engine. Vizard shows you how to build the ultimate big-blocks for the street: engines that are up to 850 hp on 91-octane pump gas, which is a monumental achievement. The Chevy big-block has been substantially under-valved, and the key to getting the best performance from this engine is to deal effectively with this design limitation. Vizard explains how to minimize intake-valve shrouding, reveals the science behind all cam-timing events, and explains how to arrive at the correct valve overlap for maximum efficiency. Vizard also covers the nuances of piston ports, rings, and connecting rods so the rotating assembly is strong and working at its peak. Finally, a special section presents a number of max-performance big-block sample builds. This volume includes a huge range of cutting-edge aftermarket parts and advanced tuning techniques. If you're serious about building a max-performance Chevy big-block engine for the street or track, you owe it to your engine and yourself to include this book in your automotive library.
Download or read book David Vizard s How to Port and Flow Test Cylinder Heads written by David Vizard and published by CarTech Inc. This book was released on 2012 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Porting heads is an art and science. It takes a craftsman's touch to shape the surfaces of the head for the optimal flow characteristics and the best performance. Porting demands the right tools, skills, and application of knowledge. Few other engine builders have the same level of knowledge and skill porting engine heads as David Vizard. All the aspects of porting stock as well as aftermarket heads in aluminum and cast-iron constructions are covered. Vizard goes into great depth and detail on porting aftermarket heads. Starting with the basic techniques up to more advanced techniques, you are shown how to port iron and aluminum heads as well as benefits of hand and CNC porting. You are also shown how to build a high-quality flow bench at home so you can test your work and obtain professional results. Vizard shows how to optimize flow paths through the heads, past the valves, and into the combustion chamber. The book covers blending the bowls, a basic porting procedure, and also covers pocket porting, porting the intake runners, and many advanced procedures. These advanced procedures include unshrouding valves, porting a shortside turn from the floor of the port down toward the valve seat, and developing the ideal port area and angle. All of these changes combine to produce optimal flow velocity through the engine for maximum power.
