Available in PDF, EPUB and Kindle. Book excerpt: Simplified wing and store models are used to determine the aerodynamic interference effects between an aircraft and a store carried beneath its wing. Inviscid flow characteristics are calculated and the results compared to an experimental wind tunnel study. The resulting vertical forces are comparable to those from the wind tunnel study when modeling the wing with a single horseshoe vortex. The remaining forces and moments are not predicted accurately. Methods for correcting the differences are suggested. Modeling the wing with multiple horseshoe vortices changes the side force values to values comparable to those from the wind tunnel study. This indicates that the method can be extended to correct the other forces and moments to more realistic values. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Aerodynamic interference between an aircraft and a store carried beneath its wing is investigated using the simplified physical model of a uniform wing of infinite span and a slender body of revolution positioned beneath the wing. The wing is represented by a vortex filament, the store by a distribution of sources and doublets along its axis of revolution, and potential flow is presumed to exist. The aerodynamic forces acting on the store while it is attached to the aircraft are computed using this model. The trajectory that the store follows after it is released is studied for mass, initial position relative to the wing, and initial angle of attack. If a store is symmetric and homogeneous, it appears to be unstable after release, and rapidly violates the small angle assumptions of the study. Several trajectories are computed, and show that the aerodynamic loads can be large enough to propel a store of considerable mass into the ai craft that released it.

Available in PDF, EPUB and Kindle. Book excerpt: Aerodynamic interference between an aircraft and wing store is studied by the use of analytical wing, fuselage, and store models. Inviscid flow is assumed and the Gothert transformation is used to correct for compressibility. An elliptic wing is represented by a bound vortex followed by a trailing vortex sheet. The fuselage and store are assumed to be slender bodies and modeled by a series of sources and doublets along their axis of revolution. Aerodynamic interference of the aircraft model is studied by observing the store in captive and free flight modes in the vicinity of the wing and fuselage models. The aerodynamic forces and moments experienced by the store as well as store trajectories are computed. Comparisons are made of store reactions (motion and trajectory) to only the wing model and to the wing and fuselage models combined. (Author).

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).

Book excerpt: Five tasks were initiated to study the aerodynamic interference between stores and aircraft. Both viscous and inviscid calculations were made. Steady state interference calculations matched well with experimental results and with other computational results. Unsteady time-accurate inviscid results showed the feasibility of using the Chimera scheme to simulate store separation. Free-fall calculations were made, demonstrating the ability to compute the new position of the store from the aerodynamic forces and moments on the store after its release from the aircraft.

This book was released on 2013-03-09 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by TPRC at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemina tion phases of the activity was transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we have concluded that it will be in the interest of all concerned if the printing and distribution of the volume were handled by a well-known publishing house to assure improved service and better communication. Hence, effective with this Volume 18, Masters Theses in the Pure and Applied Sciences will be disseminated on a worldwide basis by Plenum Publishing Corporation of New York. All back issues can also be ordered from Plenum. As we embark on this new partnership with Plenum, we also initiate a new venture in that this important annual reference work now covers Canadian universities as well as those in the United States. We are sure that this broader base will greatly enhance the value of these volumes.
