Book excerpt: The problem of hot gas ingestion in V/STOL and STOVL aircraft has motivated a set of experimental studies. Two-, three-, and four-jet configurations in cross flow were studied in ground effect. The results presented here were based on a quantitative, concentration measurement technique know as marker nephelometry. The effects of configuration, velocity ratio (freestream over jet velocity), model height, and inlet suction were investigated. The experiments were conducted in three parts. In the first part, comparisons of low speed two-, three-, and four-jet configurations were made. Measurements were made in the planes beneath the models in ground effect. As the number of jets increased, the vortical structures in the flowfield were found to move further upstream due to the increased total momentum. In the second part of the experiments, measurements were made at the inlet entry plane of the low speed two- and three-jet configurations in ground effect. The results indicated that ingestion occurred intermittently, especially in the upper portions of the inlets. The highest levels of concentrations were measured at a model height of two jet diameters. As the model height increased, the concentration levels decreased. Finally, a high speed, two-jet configuration without inlet suction was studied. The flowfield structures were generally found to move further downstream as the jet velocity increased at a constant velocity ratio. Holdeman, James D. (Technical Monitor) and Vukits, Thomas J.

Available in PDF, EPUB and Kindle. Book excerpt: Purdue University has played a leading role in providing the engineers who designed, built, tested, and flew the many aircraft and spacecraft that so changed human progress during the 20th century. It is estimated that Purdue has awarded 6% of all BS degrees in aerospace engineering, and 7% of all PhDs in the United States during the past 65 years. The University's alumni have led significant advances in research and development of aerospace technology, have headed major aerospace corporations and government agencies, and have established an amazing record for exploration of space. More than one third of all US manned space flights have had at least one crew member who was a Purdue engineering graduate (including the first and last men to step foot on the moon). The School of Aeronautics & Astronautics was founded as a separate school within the College of Engineering at Purdue University in 1945. The first edition of this book was published in 1995, at the time of the school's 50th anniversary. This corrected and expanded second edition brings the school's illustrious history up to date, and looks to Purdue's future in the sky and in space.

This book was released on 2012-12-06 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: An updated and expanded new edition of an authoritative book on flight dynamics and control system design for all types of current and future fixed-wing aircraft Since it was first published, Flight Dynamics has offered a new approach to the science and mathematics of aircraft flight, unifying principles of aeronautics with contemporary systems analysis. Now updated and expanded, this authoritative book by award-winning aeronautics engineer Robert Stengel presents traditional material in the context of modern computational tools and multivariable methods. Special attention is devoted to models and techniques for analysis, simulation, evaluation of flying qualities, and robust control system design. Using common notation and not assuming a strong background in aeronautics, Flight Dynamics will engage a wide variety of readers, including aircraft designers, flight test engineers, researchers, instructors, and students. It introduces principles, derivations, and equations of flight dynamics as well as methods of flight control design with frequent reference to MATLAB functions and examples. Topics include aerodynamics, propulsion, structures, flying qualities, flight control, and the atmospheric and gravitational environment. The second edition of Flight Dynamics features up-to-date examples; a new chapter on control law design for digital fly-by-wire systems; new material on propulsion, aerodynamics of control surfaces, and aeroelastic control; many more illustrations; and text boxes that introduce general mathematical concepts. Features a fluid, progressive presentation that aids informal and self-directed studyProvides a clear, consistent notation that supports understanding, from elementary to complicated conceptsOffers a comprehensive blend of aerodynamics, dynamics, and controlPresents a unified introduction of control system design, from basics to complex methodsIncludes links to online MATLAB software written by the author that supports the material covered in the book
