Available in PDF, EPUB and Kindle. Book excerpt: Small UAV's and flight vehicles in other atmospheres such as Mars are characterized by low Reynolds numbers. Low Reynolds number airfoil testing has been difficult to achieve and there are few centers that can accomplish this task. This study is an effort to develop a flight test system that will enable low Reynolds number tests to be performed with a simple glider design. The concept is to develop a high altitude glider that will be transported to altitudes reaching 100,000 feet or more by a helium filled balloon. At altitude, the glider will be released and will perform flight experiments as it descends. This region of Earth's atmosphere, 'near space' has the conditions desired for low Reynolds number testing as well as similar properties to the surface of Mars. With the knowledge gained from this experiment, a better understanding of accomplishing flight on Mars may be attained.

Book excerpt: Flight Test Instrumentation is a collection of papers presented at the Third International Symposium on Flight Test Instrumentation held in 1964 under the auspices of the Department of Flight of the College of Aeronautics in Cranfield, UK. The symposium provided a forum for discussing advances in flight test instrumentation and covered topics ranging from pre-detection recording in the megacycle range to some problems and uses of fuel flow measurements in supersonic aircraft. This volume is comprised of 14 chapters and begins by describing angle of attack and angle of sideslip measurements using fully de-iced non-movable differential pressure-sensing heads and low-range capacitive pressure transducers. The next chapter explores errors in stability derivative measurements that can occur due to shortcomings in instrumentation design, as well as the implications of such errors for the development of a modern supersonic aeroplane. The application of the vector plotting technique to flight flutter testing of the Hawker Siddeley Trident is then considered. Subsequent chapters focus on the use of high-accuracy instrumentation techniques for non-steady flight measurements; strain gauging for transient heating cases; and free-flight model techniques for aerodynamic research at supersonic and hypersonic speeds. This book will be a useful resource for students, practitioners, and officials of aeronautics.

Download or read book Design and Cost Considerations for High-altitude Aircraft Systems written by T. F. Cartaino and published by . This book was released on 1959 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The significant factors involved in the design of aircraft for high altitude flight are discussed within the context of a patrol or endurance application. Because of this mission constraint, only subsonic aircraft configurations with non-afterburning turbojet engines are considered. Some of the design limitations imposed by the present state-of-art are explored. The incremental cost of high altitude flight is indicated and the interaction between cost and possible operational requirements is briefly investigated. Finally, some of the possible areas for future improvement in altitude performance are delineated. (Author).
Book Synopsis Flight Test System Identification by : Roger Larsson
Download or read book Flight Test System Identification written by Roger Larsson and published by Linköping University Electronic Press. This book was released on 2019-05-15 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the demand for more advanced fighter aircraft, relying on unstable flight mechanical characteristics to gain flight performance, more focus has been put on model-based system engineering to help with the design work. The flight control system design is one important part that relies on this modeling. Therefore, it has become more important to develop flight mechanical models that are highly accurate in the whole flight envelope. For today’s modern fighter aircraft, the basic flight mechanical characteristics change between linear and nonlinear as well as stable and unstable as an effect of the desired capability of advanced maneuvering at subsonic, transonic and supersonic speeds. This thesis combines the subject of system identification, which is the art of building mathematical models of dynamical systems based on measurements, with aeronautical engineering in order to find methods for identifying flight mechanical characteristics. Here, some challenging aeronautical identification problems, estimating model parameters from flight-testing, are treated. Two aspects are considered. The first is online identification during flight-testing with the intent to aid the engineers in the analysis process when looking at the flight mechanical characteristics. This will also ensure that enough information is available in the resulting test data for post-flight analysis. Here, a frequency domain method is used. An existing method has been developed further by including an Instrumental Variable approach to take care of noisy data including atmospheric turbulence and by a sensor-fusion step to handle varying excitation during an experiment. The method treats linear systems that can be both stable and unstable working under feedback control. An experiment has been performed on a radio-controlled demonstrator aircraft. For this, multisine input signals have been designed and the results show that it is possible to perform more time-efficient flight-testing compared with standard input signals. The other aspect is post-flight identification of nonlinear characteristics. Here the properties of a parameterized observer approach, using a prediction-error method, are investigated. This approach is compared with four other methods for some test cases. It is shown that this parameterized observer approach is the most robust one with respect to noise disturbances and initial offsets. Another attractive property is that no user parameters have to be tuned by the engineers in order to get the best performance. All methods in this thesis have been validated on simulated data where the system is known, and have also been tested on real flight test data. Both of the investigated approaches show promising results.

Kossman and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2004 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper covers the construction and testing of a proof-of-concept model of a high altitude, rigid-winged, tethered aircraft. The aircraft is designed as a replacement for aerostats, to act as a payload positioning platform for communication and surveillance equipment. The initial design was found to be unstable through testing, and a series of 60 cm wingspan, small-scale models were constructed to experimentally modify the design into a stable aircraft. Once a suitable design was obtained, a 1.2 m scale model was constructed with a horizon sensing, closed-loop proportional feedback control system for lateral stability augmentation. The stability-augmented model flew stably, for extended periods. Lift and drag measurements were obtained from the flight tests and compared to theoretical calculations. A wind tunnel test was also conducted on the small-scale model to verify the flight test results. Finally, improvements to the stability control system design were suggested, and recommendations were made for larger-scale model construction.
