Book Synopsis The AFFDL-Nielsen Flow-field Study by : William T Strike (Jr.)
Download or read book The AFFDL-Nielsen Flow-field Study written by William T Strike (Jr.) and published by . This book was released on 1976 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This test was conducted in support of a program to develop a generalized analytical method for predicting the separation characteristics of stores from a high-speed aircraft (parent body). The tests were conducted in the von Karman Gas Dynamics Facility (VKF), Tunnel A, at nominal Mach numbers of 1.5, 1.76, 2.0, and 2.5 at a nominal free-stream Reynolds number of 4 x 10 to 6th power per foot. The test program involved three phases, namely flow-field surveys using a cone probe rake to determine local flow-field angles and velocity, pressure distributions on the store as it separated from a parent body, and six-component force and moment data on the store. The tests were conducted at angles of attack of zero and five degrees. This document contains a detailed description of the calibration procedure for the 20-deg half-angle cone probes and the method used to evaluate the local flow-field properties from the cone probe surface pressure and pitot pressure measurements. Also included is a comparison of integrated pressure data with the force and moment data obtained on the storebody by a balance. (Author).

Book Synopsis Study of Flow Fields and Store Forces in Close Proximity to a Triple Ejection Rack at Transonic Speeds by : Frederick K. Goodwin
Download or read book Study of Flow Fields and Store Forces in Close Proximity to a Triple Ejection Rack at Transonic Speeds written by Frederick K. Goodwin and published by . This book was released on 1981 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The information presented in this paper shows what parent aircraft effects are important when determining the forces and moments acting on a store in close proximity to a triple ejection rack. The large gradients in the store forces and moments which exist near the carriage position are demonstrated. Areas are shown in which improvements to the AFFDL/Nielsen subsonic store separation computer program are required if the launch dynamics of a store released from such a configuration are to be accurately predicted.

Book Synopsis Aerodynamics for Engineers by : John J. Bertin
Download or read book Aerodynamics for Engineers written by John J. Bertin and published by Cambridge University Press. This book was released on 2021-08-12 with total page 843 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now reissued by Cambridge University Press, this sixth edition covers the fundamentals of aerodynamics using clear explanations and real-world examples. Aerodynamics concept boxes throughout showcase real-world applications, chapter objectives provide readers with a better understanding of the goal of each chapter and highlight the key 'take-home' concepts, and example problems aid understanding of how to apply core concepts. Coverage also includes the importance of aerodynamics to aircraft performance, applications of potential flow theory to aerodynamics, high-lift military airfoils, subsonic compressible transformations, and the distinguishing characteristics of hypersonic flow. Supported online by a solutions manual for instructors, MATLABĀ® files for example problems, and lecture slides for most chapters, this is an ideal textbook for undergraduates taking introductory courses in aerodynamics, and for graduates taking preparatory courses in aerodynamics before progressing to more advanced study.

Book Synopsis Investigation of the Flow Field During the Inflation of Clustered Parachutes by : R. J. Niccum
Download or read book Investigation of the Flow Field During the Inflation of Clustered Parachutes written by R. J. Niccum and published by . This book was released on 1966 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clustered parachutes during the period of inflation were simulated by elliptical cylinders in potential flow and so-called O'Hara shape parachutes in water flow and wind tunnel experiments. The results are presented in the form of streamline and pressure distribution plots around the respective bodies. Results show that when geometric symmetry is disturbed, the flow field becomes unsymmetrical and strong attractive or repulsive forces are developed. This allows a variety of inflation modes to occur and, hence, poor cluster opening performance.
