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).

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: Mathematical expressions are derived for the interference forces and moments acting on the tails of slender plane and cruciform wing-tail combinations of general plan form in steady straight flight at combined angles of attack and sideslip. The derivatives are made within the limitations of slender-body theory under the assumption that the vortex sheet leaves the wing as flat sheet and becomes fully rolled up ahead of the tail. The derived expressions are used to calculate the steady lifts, side forces, pitching moments, and rolling moments of the number of wing-tail combinations. The effects of changes in tail height, tail length, ratio of tail span to wing span, tail incidence, and tail thickness are calculated. The resulting curves, and particularly their nonlinearities, are discussed at some length in connection with static stability. In general, the most dramatic effects are noted when the vortices shed from the wing strike the tips of the tail trailing edge.
