Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to find the throttle controls and trajectories which yield the minimum turning times for a high performance aircraft with thrust reversal capability. The aircraft remains in the vertical plane allowing only pull-up and split-s maneuvers. A second-order parameter optimization method coupled with the suboptimal control approach is used to solve the minimum time-to-turn problem. The results of the study found that trajectories restricted to the vertical plane gave different results, and in at least one case better results, than those not so constrained. The results also indicate that depending on the maneuver performed, thrust reversal is beneficial in reducing the minimum time-to-turn regardless of whether the aircraft's initial velocity is above or below corner speed. Finally, the results demonstrate that thrust reversal can be utilized for minimum time turns with resulting increases in specific energy. (AUTHOR).

Download or read book Three-dimensional, Minimum-time Flight Paths to a Point and Onto a Line for a Supersonic Aircraft with a Maximum Mach Number Constraint written by Stanford University. Department of Aeronautics and Astronautics and published by . This book was released on 1972 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimal control theory and the energy-state approximation are used to determine the thrust, altitude, and bank angle programs for minimum-time flight paths of a supersonic aircraft from an initial energy, heading, and horizontal position to a specified final energy, heading, and point or line in a horizontal plane. Constraints on maximum and minimum thrust, stall angle-of-attack, maximum Mach number, maximum dynamic pressure, and maximum normal load factor are considered. The problem is restricted to those cases in which the flight path is long enough that the maximum Mach number is reached during the flight. Numerical results are presented for a typical supersonic aircraft capable of Mach 2.0 flight. (Author).

Download or read book Optimal Trajectories in Atmospheric Flight written by Nguyen Vinh and published by Elsevier. This book was released on 2012-12-02 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimal Trajectories in Atmospheric Flight deals with the optimization of trajectories in atmospheric flight. The book begins with a simple treatment of functional optimization followed by a discussion of switching theory. It then presents the derivation of the general equations of motion along with the basic knowledge in aerodynamics and propulsion necessary for the analysis of atmospheric flight trajectories. It goes on to the study of optimal trajectories by providing the general properties of the optimal aerodynamic controls and the integrals of motion. This is followed by discussions of high subsonic and supersonic flight, and approximation techniques to reduce the order of the problem for a fast computation of the optimal trajectory. The final chapters present analyses of optimal reentry trajectories and orbital maneuvers. This book is intended as a reference text for scientists and engineers wanting to get into the subject of optimal trajectories in atmospheric flight. If used for teaching purposes, the book is written in a self-contained way so that a selective use of the material is at the discretion of the lecturer. The first 11 chapters are sufficient for a one-semester course with emphasis on optimal maneuvers of high performance aircraft.

This book was released on 2012-12-06 with total page 335 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 dissemination 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 con cerned if the printing and distribution of the volume 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 Cor poration 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 26 (thesis year 1981) a total of 11 ,048 theses titles from 24 Canadian and 21 8 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 26 reports theses submitted in 1981, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

This book was released on 2002 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: RTCA Special Committee 186 has recently adopted a series of changes to the original Minimum Aviation System Performance Standards (MASPS) for Automatic Dependent Surveillance Broadcast (ADS-B). The new document will be published as DO-242A. Major changes to the MASPS include a significant restructuring and expansion of the intent parameters for future ADS-B systems. ADS-B provides a means for aircraft to exchange information about their intended trajectories with each other and with ground systems. NASA and Boeing have played significant roles in recommending these changes and providing supporting analysis. The intent changes are anticipated to provide substantial benefits to several programs and operational concepts under development by the two organizations. Major changes include the addition of Target State reports and the replacement of Trajectory Change Point reports with Trajectory Change reports.
