This book was released on 1973 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method for determining the subsonic aerodynamic interference between a planar wing with pylons and a single axisymmetric body has been developed and evaluated. The wing and body solutions were obtained independently using a simple horseshoe vortex system and a three-dimensional point source distribution, respectively. A vortex image system based on the two-dimensional theory of images was then added to the body to maintain the tangent-flow boundary condition in the non-uniform wing flow field. Both the influence of the vortex image system within the body and the body flow field effects at the wing were evaluated. No significant change in the wing vortex strength distribution resulted so that it was unnecessary to iterate the isolated wing solution. The theoretical results for incompressible flow were compared with pressure distributions obtained from low-speed wind tunnel tests of the wing-body configuration. The correlation was generally good.

Mattasits and published by . This book was released on 1975 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted in the Aerodynamic Wind Tunnel (4T) to evaluate the validity of weapon aerodynamics acquired from theoretical calculations which employed mathematical models to simulate actual test hardware and to assess the problems encountered during the separation of various weapon shapes, at transonic flight conditions, from the number one TER position. The data will also be used to aid in the development of a mathematical method for predicting store separation characteristics. Data were obtained at Mach numbers from 0.5 to 1.3. Force and pressure distribution measurements were obtained to assess the influence of angle of attack and both linear and angular store displacements from the carriage position. Store models were separated from a TER mounted on the inboard pylon of a half-span wing similar in planform to the wing of the F-4 aircraft. Data were obtained on 0.10-scale models of the M-117 and maximum volume bombs. Test results showed that large nose-down pitching-moment coefficients were encountered by all store models at the number one TER carriage position. Complete separation trajectories were obtained only at a Mach number of 0.5 for all 16-in.-diam store models. Decreasing store model diameter increased the maximum Mach number at which complete trajectories were obtained. (Author).

Download or read book Mutual Aerodynamic Interference Effects for Multiple Bodies by the Cross flow Corrections Method written by Fred W. Martin and published by . This book was released on 1971 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complexity of the flow field beneath an aircraft with external stores is examined analytically. Equations are produced for computing store separation trajectories, based on mutual interference flow fields between the aircraft and the store. The circle theorem and the small disturbances theory are used in establishing the perturbations responsible for the flow field interference. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The mutual aerodynamic interference problem for two axisymmetric bodies has been analyzed using the image system technique. In order to facilitate this analysis, it has been assumed that small perturbation solutions are valid. It is further assumed that the external stores are slender bodies and that the mutual interference can be analyzed by first assuming a cross-flow solution. The image system in the cross-flow plane consists of source-sink pairs appropriately located by using the Milne-Thomson circle theorem. The actual three-dimensional source-sink paris are displaced from the body axis according to the cross flow image system. Their strengths are then determined by the Rankine method. Good agreement has been found between the theoretical and experimental results. (Author).

This book was released on 1976 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report contains the results of an experimental program to evaluate the effect of the 4T Captive Trajectory System on the separation characteristics of typical stores. The models selected as being generally representative of external stores were the modified BLU-27B/B configuration with and without fins. The aircraft model selected for this test was the F-111. To assess the aerodynamic interference of the Captive Trajectory System on the store and its trajectory, four sting lengths were used to position the store model at varying distances from the support system. Data were obtained at Mach numbers of 0.4, 0.8, 0.9, 1.1, and 1.2. Captive trajectories simulating store separation from the aircraft model were obtained; forces on the store were measured while the store was moved vertically away from the marriage position; and force data on the store were obtained as it was yawed in a location as far removed as possible from the aircraft model. It was concluded that the Captive Trajectory System has little or no effect on the store loads and trajectory development. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Much-needed, fresh approach that brings a greater insight into the physical understanding of aerodynamics Based on the author’s decades of industrial experience with Boeing, this book helps students and practicing engineers to gain a greater physical understanding of aerodynamics. Relying on clear physical arguments and examples, Mclean provides a much-needed, fresh approach to this sometimes contentious subject without shying away from addressing "real" aerodynamic situations as opposed to the oversimplified ones frequently used for mathematical convenience. Motivated by the belief that engineering practice is enhanced in the long run by a robust understanding of the basics as well as real cause-and-effect relationships that lie behind the theory, he provides intuitive physical interpretations and explanations, debunking commonly-held misconceptions and misinterpretations, and building upon the contrasts provided by wrong explanations to strengthen understanding of the right ones. Provides a refreshing view of aerodynamics that is based on the author’s decades of industrial experience yet is always tied to basic fundamentals. Provides intuitive physical interpretations and explanations, debunking commonly-held misconceptions and misinterpretations Offers new insights to some familiar topics, for example, what the Biot-Savart law really means and why it causes so much confusion, what “Reynolds number” and “incompressible flow” really mean, and a real physical explanation for how an airfoil produces lift. Addresses "real" aerodynamic situations as opposed to the oversimplified ones frequently used for mathematical convenience, and omits mathematical details whenever the physical understanding can be conveyed without them.
