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.

This book was released on 1980 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic drop testing is a method of trajectory simulation whereby store models which are both geometrically and dynamically scaled are released in the wind tunnel air stream and the resulting trajectories are mapped photographically. Drop testing is often used when captive trajectory testing is not feasible or for final trajectory verification prior to flight tests. (Author).

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).
Download or read book Use of the Flow Angularity Technique for Predicting Store Separation Trajectories written by Stephen C. Korn and published by . 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).

Download or read book Fast Radial Basis Functions for Engineering Applications written by Marco Evangelos Biancolini and published by Springer. This book was released on 2018-03-29 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the first “How To” guide to the use of radial basis functions (RBF). It provides a clear vision of their potential, an overview of ready-for-use computational tools and precise guidelines to implement new engineering applications of RBF. Radial basis functions (RBF) are a mathematical tool mature enough for useful engineering applications. Their mathematical foundation is well established and the tool has proven to be effective in many fields, as the mathematical framework can be adapted in several ways. A candidate application can be faced considering the features of RBF: multidimensional space (including 2D and 3D), numerous radial functions available, global and compact support, interpolation/regression. This great flexibility makes RBF attractive – and their great potential has only been partially discovered. This is because of the difficulty in taking a first step toward RBF as they are not commonly part of engineers’ cultural background, but also due to the numerical complexity of RBF problems that scales up very quickly with the number of RBF centers. Fast RBF algorithms are available to alleviate this and high-performance computing (HPC) can provide further aid. Nevertheless, a consolidated tradition in using RBF in engineering applications is still missing and the beginner can be confused by the literature, which in many cases is presented with language and symbolisms familiar to mathematicians but which can be cryptic for engineers. The book is divided in two main sections. The first covers the foundations of RBF, the tools available for their quick implementation and guidelines for facing new challenges; the second part is a collection of practical RBF applications in engineering, covering several topics, including response surface interpolation in n-dimensional spaces, mapping of magnetic loads, mapping of pressure loads, up-scaling of flow fields, stress/strain analysis by experimental displacement fields, implicit surfaces, mesh to cad deformation, mesh morphing for crack propagation in 3D, ice and snow accretion using computational fluid dynamics (CFD) data, shape optimization for external aerodynamics, and use of adjoint data for surface sculpting. For each application, the complete path is clearly and consistently exposed using the systematic approach defined in the first section.
