This book was released on 1971 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is being developed for solving the store separation trajectory problem by flow angularity techniques. This approach uses experimentally measured interference flow field data coupled with store free stream aerodynamic coefficients. Presently, the flow field about the inboard triple ejector rack loaded with M-117 bombs at Mach 0.85 on the F-4 aircraft is being used to predict the trajectory of other stores launched from the inboard triple ejector rack at subsonic and transonic Mach numbers. Sample comparisons of trajectories produced by the captive trajectory system are presented. This technique allows calculation of the trajectory until the store impacts on the ground. Sample miss distances caused by the interference flow field calculated using the flow angularity technique are presented for the M-117 bomb. (Author).

This book was released on 1972 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the external flow fields caused by various weapon configurations on the wing of an F-4 aircraft, verifies assumptions made in the flow angularity technique, and presents the documentation for the 'Flow Angularity Computer Program' with example trajectories. The flow angularity program is presently capable of calculating the trajectories of stores off the inboard and outboard wing stations in either single, triple ejector rack, or multiple ejector rack configurations. The assumptions made in the flow angularity technique have been analyzed and generally validated as good approximations. (Author).

This book was released on 1974 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this report is to present a prediction method for determining the forces, moments, and six-degree-of-freedom trajectories associated with stores released from single, TER, or MER configurations on fighter-bomber aircraft up to the critical speed. A secondary objective is to present important experimental results and comparison with theory from an extensive wind-tunnel test program designed to provide data to test the theory through systematic measurements of flow fields, store load distributions, store forces and moments, and captive-store trajectories.

This book was released on 1979 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted on a four-finned, ogive-cylinder store model which was mounted on the von Karman Gas Dynamics Facility (VKF) Captive Trajectory System (CTS) in the Arnold Engineering Development Center (AEDC) Supersonic Wind Tunnel A. The purpose of these tests was to provide information necessary for an independent check on the VKF CTS trajectory mode results. Grid and trajectory data were obtained for the store, both in the free stream and in the interference flow field of a generalized parent-aircraft model. The Mach number was 1.63, with Reynolds numbers per foot of 5.0 and 3.8 million. Grid data from these tests were used in conjunction with the Air Force Flight Dynamics Laboratory (AFFDL) Six-Degree-of-Freedom Computer Program (SDFCP) to simulate the trajectories obtained by the VKF CTS. These SDFCP simulations compared favorably with the CTS trajectories, providing an important compared favorably with the CTS trajectories, providing an important independent verification of the VKF CTS trajectory mode results. This report documents this validation effort and provides a general description of the VKF CTS as well as guidelines for potential users of this system. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A test was conducted in the Arnold Engineering Development Center (AEDC) Aerodynamic Wind Tunnel (1T) of the Propulsion Wind Tunnel Facility (PWT) to measure the flow fields about several wing/pylon/store configurations. Test models included a wall-mounted swept wing, five-percent MK-83 and M-117 stores, and swept and unswept pylons. Flow-field velocity measurements, made by using a three-component laser velocimeter, are presented. (Author).

This book was released on 1996 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mathematical equations of motion for ground simulation of the separation trajectories of stores from aircraft are developed in this document. The equations have application to both analytical and wind tunnel captive trajectory store separation testing. The equations of motion as presented here include features not previously available in AEDC analytical and wind tunnel simulations such as arbitrary aircraft maneuvers, more rigorous models of the specific pivot hardware used by some aircraft, and downrail motions with all components of kinematic acceleration (including Corlolis effects) modeled. The data reduction equations for free-falling instrumented store models are also included.

Book excerpt: This AGARDograph is a systematic collection of experimental results for use of engineers and designers, limited to externally carried, unpowered, unguided stores. In the sections dealing with store trajectories, the physical situation is described, the method of solution is indicated, and the final results are presented. Emphasis is on store motion in traversing the parent aircraft flowfield, with criteria for safe separation and methods of calculating flight path. Windtunnel test techniques are described, and some information on flight testing given. Analytical treatment is compared with flight and tunnel results. There are brief mentions of ejection systems and the effect of stores on aircraft performance.

This book was released on 2012-12-06 with total page 386 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 thougtit 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 volumes were handled by an interna tional 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 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.
