Download or read book Aerodynamic Interference Effects on Various Weapon Shapes in the Flow Field of a Transonic Wing Configuration at Mach Numbers from 0 5 to 1 3 written by G. R. 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).

This book was released on 1981 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental program was conducted to parametrically study the interference on an afterbody model that would be produced by the aft-support blade used with a wingtip support system. Geometric variables included the blade axial location, thickness, span, chord, and leading- and trailing-edge contours. Data were obtained over the Mach number range from 0.6 to 1.2 with the model at zero angle of attack. Interference was evaluated by comparing afterbody drag from a reference configuration, which had the aft-support blade removed, to the various configurations with a blade installed. A reasonable correlation of the blade interference effects on the afterbody drag coefficient was obtained, which included the influence of support blade axial position and blockage. Decreasing blade leading-edge bluntness by a factor of two resulted in a significant reduction of interference in the Mach number range from 0.9 to 1.1. Significantly greater interference was measured without jet flow than with jet flow. It is shown that a Euler equation computer code is a useful tool for the design of minimum interference support systems. (Author).

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: Several theoretical and empirical procedures are combined into a single computer program to predict lift, drag, and center of pressure on quite general wing-body geometries. The method is applicable for Mach number zero to three and angle-of-attack zero to about fifteen degrees. Computed results for several configurations compare well with experimental and other analytical results. It costs about five dollars per Mach number to compute the static aerodynamics of a typical wing-body shape on the CDC 6700 computer.

This book was released on 1976 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method of solution for the aerodynamic flow field about two bodies at angle of attack including mutual interference effects has been devised for bodies with circular cross-section. The analytical method used is a modification of a method of solution for the flow about axisymmetric bodies in close proximity at zero angle of attack. As a demonstration of this method, the flows about one, two and three finless M-117 bomb shapes were investigated. Theoretical pressure distributions are presented for the two and three body cases. For the three body case, experimental data is available; however, there is poor agreement with data thought primarily to be because of flow separation along the tails of the bombs. A non-axisymmetric modification of the M-117 bomb shape was developed in order to simulate the flow separation. The analytical results of this effort are compared with the experimental data.
