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).

Available in PDF, EPUB and Kindle. Book excerpt: Separation trajectory data were obtained to investigate some possible ways to reduce the nose-down pitch of the SUU-51B/B store during separation from the Triple Ejection Rack (TER) on the F-4C aircraft. Data were obtained to assess the influence on the store separation characteristics resulting from (1) changing the store mass properties (ballasting), (2) modifying the TER geometry to represent removal of the nose fairing, (3) changing the store carriage location on the TER, (4) modifying the store nose geometry, and (5) applying dual ejector forces to the store during separation. Separation trajectories were obtained for release from the TER on the inboard pylon at Mach numbers from 0.66 to 1.1 for level flight at 5000-ft altitude. In addition to the trajectory data, force and moment data were obtained on the SUU-51B/B to assess the influence on store loads of (1) changes in store position relative to the rack, and (2) the modified nose geometry. Results of the test show that the dual ejector forces were most effective in reducing the store nose-down pitch. Separation of the ballasted store from the modified TER produced the best results of all combinations using the single ejector. (Author).

This book was released on 1971 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted in the Aerodynamic Wind Tunnel (4T) using 0.05-scale models to investigate the separation characteristics of the SUU-51 Laser-Guided Dispenser Munition (LGDM) from Triple Ejection Rack and Multiple Ejection Rack locations on the inboard and centerline pylons, respectively, of the F-4C aircraft. Captive-trajectory store separation data were obtained at Mach numbers from 0.66 to 0.90, angles of attack from 0.3 to 2.1, and a simulated altitude of 5000 ft. At selected test conditions, parent-aircraft dive angles of 30 and 45 deg were simulated. Free-stream force and moment data were also obtained on the SUU-51 (LGDM) model at Mach numbers from 0.66 to 0.95 at store angles of attack from -6 to 20 deg. Generally, the store initially separated from the parent aircraft without store-to-parent contact. However, most of the trajectories were terminated after short time intervals because of a rapid pitch and yaw motion of the store. This termination was the result of limitations imposed by the test installation, such as sting-to-parent-aircraft contact, a store support system travel limit, or a balance load limit. (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).

Summers and published by . This book was released on 1972 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Separation trajectory data were obtained to assess the effectiveness of triple ejection rack (TER) geometry changes in reducing the nose-down pitch motion of the SUU-51 B/B and M-117 stores during separation from the rack on the inboard wing pylon of the F-4C aircraft. Eleven different TER configurations, consisting of changes in the forward and/or aft fairing geometry, were used during the test. Effects on the trajectories resulting from changes in the SUU-51 B/B fin geometry and the addition of a stagnation plate covering one fin quadrant of the SUU-51 B/B were also obtained. In addition, pressure distribution data were obtained on an ogive-cylinder store in the carriage position on the standard TER and on a TER with a modified forward fairing. Separation trajectory data were obtained at Mach numbers of 0.66 and 0.90, and pressure data were obtained at a Mach number of 0.90. The trajectory data show that only one modification to the TER forward fairing reduced the store nose-down pitch (relative to the standard TER) at both Mach numbers. Addition of the stagnation plate covering one fin quadrant of the SUU-51 B/B reduced the nose-down pitch at M Free-Stream Mach Number = 0.90 and produced a nose-up pitch motion at M Free-Stream Mach Number = 0.66. Pressure data on the ogive-cylinder store (on TER position No. 1) show that about 75 percent of the nose-down pitching moment results from the pressure distribution on the store surface forward of the center of gravity and that the reductions in pitching moment resulting from modification to the forward fairing of the TER also are caused by pressure changes on the forward portion of the store.

Book excerpt: Wind tunnel captive trajectory tests were conducted to investigate the separation characteristics of six stores from the wing pylons and racks of the A-7D aircraft. The stores tested represented possible combinations of munitions to be carried by the A-7D when performing search and rescue missions. Separation trajectory data were obtained for the loaded and expended SUU-23/A gun pod, CBU-12A/A, CBU-46/A LAU-3/A, LAU-68A/A, and the expended CBU-30/A. Trajectories were obtained at Mach numbers from 0.325 to 0.814 with aircraft angle of attack corresponding to level flight at 4000-ft altitude. For selected configurations, data were obtained to assess the influence of changes in the applied ejector forces during separation from the MAU-12B/A pylon rack. The stores separated without contacting the aircraft with only two exceptions.

Mattasits and published by . This book was released on 1974 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: A test was conducted in the Aerodynamic Wind Tunnel (4T) to evaluate the effects of the SCANA (shape No. 1) modification to the F-111 fuselage on store separation characteristics and to determine store aerodynamic coefficients when located at, or near, the inboard and outborad pivot pylons of the F-111 aircraft. Data were obtained at Mach numbers from 0.40 to 1.30 to assess the influence of the aircraft angle of attack, wing-sweep angle, and the presence of the SCANA turret. Trajectory data were obtained on 1/24-scale models of the MK-84 LGB and MK-84 EOGB guided bombs and the SUU-30 H/B dispenser munition. This report contains a description of the test, information to identify the test conditions and configurations for all data taken, and sufficient plotted data to show the various effects on the store model trajectories and aerodynamic loads. Test results indicate no significant alteration in store trajectories when the SCANA turret is added to the F-111E aircraft.

This book was released on 1971 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted in the Aerodynamic Wind Tunnel (4T) using 0.05-scale models to investigate the separation characteristics of the unfinned and finned BLU-IC/B, M-11GP, MK-82GP, and MK-82SE when released from various wing pylon locations on the A-7D aircraft. Captive trajectory data were obtained at Mach numbers from 0.34 to 0.95 at simulated pressure altitudes from 5000 to 7000 ft. The parent aircraft angle of attack was varied from 1.8 to 12.3, depending on Mach number, climb angle, and simulated altitude. At selected test conditions, parent climb angles of 0, -35, -50, and -70 deg were simulated. In some cases, the separation trajectories of the BLU-1C/B were initiated at the end of the ejector piston stroke using flight-test data to determine the initial store positions and velocities. In general, the separation trajectories agreed well with flight-test data for the trajectory interval of the test. For the trajectory intervals of the test, most of the stores separated from the parent aircraft without store-to-parent contact. (Author).
Download or read book Store Separation Testing Techniques at the Arnold Engineering Development Center written by J. P. Billingsley and published by . 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).
