Download or read book The Use of Aeroelastic Wind Tunnel Models to Prove Structural Design written by H. Hoenlinger and published by . This book was released on 1986 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a wind tunnel study on an aeroelastic carbon fiber fin/rudder model it is demonstrated how structural design methods can be checked by experiment, beginning in an early stage of the design. Emphasis was put on the static aeroelastic investigations which become more important high performance A/C design. Transonic measurements with a rigid balance based on piezo force transducers and an opto-electronic deformation measurement method were successfully performed. It was tried to evaluate rudder efficiencies from these aeroelastic measurements. A non-linear behaviour of the rudder based on geometrical coupling with the fin box played an important role in the test evaluation.

Download or read book Design and Construction of a Wind Tunnel Model with Active Variable Camber Continuous Trailing Edge Flap for Aeroelastic in flight Shape Optimization Tests written by Nathan Precup and published by . This book was released on 2018 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: An aeroelastically scaled wing wind tunnel model was designed and fabricated for low-speed wind tunnel tests of real-time optimization-based continuous camber and twist shaping concepts for the SSCI-DIRECT project. The model has twelve independently controlled trailing edge control surfaces that can be actively driven while testing is underway. Development of the model follows the successful development and wind tunnel tests of smaller VCCTEF configured aeroelastic models which were fitted with manually adjusted flaps. The new active model packages the flap actuators completely within the outer mold line of the wing. Detailed analytical models for the structural dynamic and aeroelastic behavior of the new model were validated by static loads and modal tests. Wind tunnel runs were carried out to measure lift and drag characteristics of the new model and to gain experience with its continuous communication with the data acquisition system of the wind tunnel and the control algorithms. The wind tunnel model is available for further testing.
Download or read book Wind Tunnel Testing of High Rise Buildings written by Peter Irwin and published by Routledge. This book was released on 2013-06-19 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1960s, wind tunnel testing has become a commonly used tool in the design of tall buildings. It was pioneered, in large part, during the design of the World Trade Center Towers in New York. Since those early days of wind engineering, wind tunnel testing techniques have developed in sophistication, but these techniques are not widely understood by the designers using the results. As a direct result, the CTBUH Wind Engineering Working Group was formed to develop a concise guide for the non-specialist. The primary goal of this guide is to provide an overview of the wind tunnel testing process for design professionals. This knowledge allows readers to ask the correct questions of their wind engineering consultants throughout the design process. This is not an in-depth guide to the technical intricacies of wind tunnel testing, it focusses instead on the information the design community needs, including: a unique methodology for the presentation of wind tunnel results to allow straightforward comparison of results from different wind tunnel laboratories. advice on when a tall building is likely to be sufficiently sensitive to wind effects to benefit from a wind tunnel test background for assessing whether design codes and standards are applicable details of the types of tests that are commonly conducted descriptions of the fundamentals of wind climate and the interaction of wind and tall buildings This unique book is an essential guide for all designers of tall buildings, and anyone else interested in the process of wind tunnel testing for tall buildings.

L. Holt and published by . This book was released on 1975 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high Reynolds number transonic wind tunnel (HIRT) has been needed for some years. The proposed HIRT facility will provide such a tool. The usefulness of the HIRT facility will be largely influenced by the ability of industry to design and build wind tunnel models for an acceptable cost capable of operating within the severe environment of the tunnel. A test plan, which encompasses several critical conditions within the flight envelope, is described for two configurations.

Available in PDF, EPUB and Kindle. Book excerpt: Downscaled physical models, also referred to as subscale models, have played an essential role in the investigation of the complex physics of flight until the recent disruption of numerical simulation. Despite the fact that improvements in computational methods are slowly pushing experimental techniques towards a secondary role as verification or calibration tools, real-world testing of physical prototypes still provides an unmatched confidence. Physical models are very effective at revealing issues that are sometimes not correctly identified in the virtual domain, and hence can be a valuable complement to other design tools. But traditional wind-tunnel testing cannot always meet all of the requirements of modern aeronautical research and development. It is nowadays too expensive to use these scarce facilities to explore different design iterations during the initial stages of aircraft development, or to experiment with new and immature technologies. Testing of free-flight subscale models, referred to as Subscale Flight Testing (SFT), could offer an affordable and low-risk alternative for complementing conventional techniques with both qualitative and quantitative information. The miniaturisation of mechatronic systems, the advances in rapid-prototyping techniques and power storage, as well as new manufacturing methods, currently enable the development of sophisticated test objects at scales that were impractical some decades ago. Moreover, the recent boom in the commercial drone industry has driven a quick development of specialised electronics and sensors, which offer nowadays surprising capabilities at competitive prices. These recent technological disruptions have significantly altered the cost-benefit function of SFT and it is necessary to re-evaluate its potential in the contemporary aircraft development context. This thesis aims to increase the comprehension and knowledge of the SFT method in order to define a practical framework for its use in aircraft design; focusing on low-cost, short-time solutions that don’t require more than a small organization and few resources. This objective is approached from a theoretical point of view by means of an analysis of the physical and practical limitations of the scaling laws; and from an empirical point of view by means of field experiments aimed at identifying practical needs for equipment, methods, and tools. A low-cost data acquisition system is developed and tested; a novel method for semi-automated flight testing in small airspaces is proposed; a set of tools for analysis and visualisation of flight data is presented; and it is also demonstrated that it is possible to explore and demonstrate new technology using SFT with a very limited amount of economic and human resources. All these, together with a theoretical review and contextualisation, contribute to increasing the comprehension and knowledge of the SFT method in general, and its potential applications in aircraft conceptual design in particular.
