Download or read book Fighter Pilot s Heaven written by Donald S. Lopez, Sr. and published by Smithsonian Institution. This book was released on 2001-03-17 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fighter Pilot's Heaven presents the dramatic inside story of the American military's transition into the jet age, as told by a flyer whose life depended on its success. With colorful anecdotes about fellow pilots as well as precise technical information, Donald S. Lopez describes how it was to be “behind the stick” as a test pilot from 1945 to 1950, when the U.S. military was shifting from war to peacetime operations and from propeller to jet aircraft. An ace pilot who had served with Gen. Claire Chennault's Flying Tiger Fighter Group, Lopez was assigned at the close of World War II to the elite Proof Test Group of the Air Proving Ground Command. Located at Eglin Field (later Eglin Air Force Base) in Florida, the group determined the operational suitability of Air Force weapons systems and aircraft and tested the first operational jet, the P-80 Shooting Star. Jet fighters required new techniques, tactics, and weaponry. Lopez recounts historic test flights in the P-59, P-80, and P-84, among other planes, describing complex combat maneuvers, hair-raising landings in unusual positions, and disastrous crashes and near crashes. This memoir is peppered with lively accounts of many pilots and their colleagues, revealing how airmen coped with both exhilarating successes and sometimes tragic failures.

Book excerpt: The scope of this paper is to give a realistic overall picture about flight testing of fighter aircraft today and trends for the future. It is shown whether, where and to what extent flight testing is and will be necessary. Especially the implications of advanced fighter aircraft concepts on the test program are discussed regarding the high technology standard of the complete weapon system and the operational requirements. It is concluded that best equipped facilities together with a well organized management are mandatory. The introduction of up-to-date scientific computer systems and the development of new software seems to be a permanent requirement to handle the streams of data which confront the flight test engineer. Early plannings and preparations are required to integrate as many tasks as possible per flight in order to save expensive flying time. Finally an overview of flight test disciplines is given. It is shown that flight test is an universal discipline. Consequently areas of main test effort only and corresponding test methods to be applied are discussed in more detail.

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.
Download or read book Contrails over the Mojave written by George J Marrett and published by Naval Institute Press. This book was released on 2014-07-15 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Contrails over the Mojave George Marrett takes off where Tom Wolfe’s The Right Stuff ended in 1963. Marrett started the Air Force Test Pilot School at Edwards AFB only two weeks after the school’s commander, Col. Chuck Yeager, ejected from a Lockheed NF-104 trying to set a world altitude record. He describes life as a space cadet experiencing 15 Gs in a human centrifuge, zero-G maneuvers in a KC-135 “Vomit Comet,” and a flight to 80,000 feet in the F-104A Starfighter. After graduating from Yeager’s “Charm School,” he was assigned to the Fighter Branch of Flight Test Operations, where he flew the latest fighter aircraft and chased other test aircraft as they set world speed and altitude records. Marrett takes readers into the cockpit as he “goes vertical” in a T-38 Talon, completes high-G maneuvers in an F-4C Phantom, and conducts wet-runway landing tests in the accident-prone F-111A Aardvark. He writes about Col. “Silver Fox” Stephens setting a world speed record in the YF-12 Blackbird and Bob Gilliland testing speed stalls in the SR-71 spy plane, but he also relives stories of crashes that killed test pilot friends. He recounts dead-sticking a T-38 to a landing on Rogers Dry Lake after a twin-engine failure and conducting dangerous tail hook barrier testing in a fighter jet without a canopy. A mysterious UFO sighting in the night sky above the Mojave Desert, known as “The Edwards Encounter,” also receives Marrett’s attention. Whether the author is assessing a new aircraft’s performance or describing the experiences of test pilots as they routinely faced the possibility of death, this look at the golden age of flight testing both thrills and informs.

Download or read book On Subscale Flight Testing written by Alejandro Sobron and published by Linköping University Electronic Press. This book was released on 2018-11-05 with total page 112 pages. 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.

Download or read book Fighter Aircraft Performance Modeling Simulation and Flight Testing for Research and Development written by Terrell E. Greene and published by . This book was released on 1968 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the methods available for investigating in detail the performance of real or hypothetical fighter aircraft systems are a spectrum of simulation techniques ranging from pure computer modeling, on the one hand, to flight tests simulating combat operations, on the other. Intermediate between these techniques, in several senses, is simulation involving one or more pilots on line with a computer and display system, 'flying' simulated aircraft in real time. Although all three classes of technique involve varying degrees of simulation, for ease of expression they are referred to here as modeling, simulation, and flight testing. (Author).

Download or read book The Cutting Edge written by Mark A. Lorell and published by Rand Corporation. This book was released on 1998 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proposition that innovation is critical in the cost-effective design and development of successful military aircraft is still subject to some debate. RAND research indicates that innovation is promoted by intense competition among three or more industry competitors. Given the critical policy importance of this issue in the current environment of drastic consolidation of the aerospace defense industry, the authors here examine the history of the major prime contractors in developing jet fighters since World War II. They make use of an extensive RAND database that includes nearly all jet fighters, fighter-attack aircraft, and bombers developed and flown by U.S. industry since 1945, as well as all related prototypes, modifications, upgrades, etc. The report concludes that (1) experience matters, because of the tendency to specialize and thus to develop system-specific expertise; (2) yet the most dramatic innovations and breakthroughs came from secondary or marginal players trying to compete with the industry leaders; and (3) dedicated military R&D conducted or directly funded by the U.S. government has been critical in the development of new higher-performance fighters and bombers.
