This book was released on 1984 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this Australian report, the performance of a series of low-speed wind tunnels designed to operate at various maximum pressures ranging from 2 to 5 atmospheres is estimated and compared with the performance of a similar atmospheric tunnel on the basis of capital cost and power input. The choice of the design of a new tunnel is usually influenced by cost and power considerations and it is important to provide the most capable design and to maximize performance within given limits of these variables. Pressurization offers a major advantage in allowing Reynolds number (RN) and Mach number (MN) effects to be investigated separately. This can be particularly important for tests of modern aircraft configurations operating at high lift. For the same capital cost and consumption, pressurization allows the maximum RN and MN to be increased substantially, but the working section is much smaller. This may make it difficult to satisfy some test requirements particularly for V/STOL aircraft. Models for a pressurized tunnel are also more complex and may be more costly because they must withstand much higher aerodynamic loads. To illustrate the effects of tunnel pressurization the analysis is applied to a tandem section low-speed tunnel previously suggested as suitable for future Australian test requirements. Keywords include: Subsonic wind tunnels, and Model tests.

This book was released on 2022-08-31 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Academic Paper from the year 2021 in the subject Engineering - Aerospace Technology, grade: A, , course: Aerospace Technology II, language: English, abstract: Wind tunnels are a great way of obtaining precise and accurate data on an aerofoil or model aircraft. They are crucial because they help engineers save a lot on resources; rather than having to make a full prototype by "winging it", as they say, with a wind tunnel, it is possible to test a collection of low-cost models prior to the prototyping stage in order to find the best configuration for a design. As such, this assignment will cover the operation of wind tunnels from multiple points of view, looking at the various uses of a wind tunnel both from theoretical and practical points of view.

Available in PDF, EPUB and Kindle. Book excerpt: A brand-new edition of the classic guide on low-speed wind tunnel testing While great advances in theoretical and computational methods have been made in recent years, low-speed wind tunnel testing remains essential for obtaining the full range of data needed to guide detailed design decisions for many practical engineering problems. This long-awaited Third Edition of William H. Rae, Jr.'s landmark reference brings together essential information on all aspects of low-speed wind tunnel design, analysis, testing, and instrumentation in one easy-to-use resource. Written by authors who are among the most respected wind tunnel engineers in the world, this edition has been updated to address current topics and applications, and includes coverage of digital electronics, new instrumentation, video and photographic methods, pressure-sensitive paint, and liquid crystal-based measurement methods. The book is organized for quick access to topics of interest, and examines basic test techniques and objectives of modeling and testing aircraft designs in low-speed wind tunnels, as well as applications to fluid motion analysis, automobiles, marine vessels, buildings, bridges, and other structures subject to wind loading. Supplemented with real-world examples throughout, Low-Speed Wind Tunnel Testing, Third Edition is an indispensable resource for aerospace engineering students and professionals, engineers and researchers in the automotive industries, wind tunnel designers, architects, and others who need to get the most from low-speed wind tunnel technology and experiments in their work.
