Available in PDF, EPUB and Kindle. Book excerpt: The captive-trajectory store-separation system of the Aerodynamic Wind Tunnel, Transonic (4T), provides the capability for determining the separation trajectory of a store in the vicinity of the parent aircraft. This system may also be used as a six-degree-of-freedom support for conventional force tests with or without a parent installed, and as a pressure probe or transducer mounting platform for flow field surveys in the vicinity of a model. With the store and parent independently supported in the tunnel, trajectory generation involves measurement of forces and moments acting on the captive store model, converting these to full-scale adding other forces and moments which may be applied to the full-scale store, solving the equations of motion for store acceleration, integrating these equations to find store displacement, converting this movement to model scale, and physically moving the store model along its flight path. This report describes the captive-trajectory store-separation system and its testing capabilities and presents the technique used for trajectory generation. (Author).

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).

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).

This book was released on 1971 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wind tunnel test was conducted using 0.05-scale models to study the separation characteristics of the SUU-51/B external store with modified tail fins from the F-4C aircraft. Captive-trajectory store-separation data were obtained for two store cg locations and for 10 store wing loading configurations. The separation trajectories were initiated from the right-wing inboard pylon station utilizing the Triple Ejection Rack and from the centerline pylon utilizing the Multiple Ejection Rack. The flight conditions simulated were Mach numbers from 0.66 to 0.90 at an altitude of 5000 ft. Parent aircraft dive angles of 0 and 45 deg were simulated. (author).
