This book was released on 1967 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: A preliminary study is reported on certain aspects of the problem of external stores separating from a carrier vehicle. A search of the available literature resulted in the identification of some 23 documents which were strongly relevant to the subject of investigation. These are listed, and summaries are given on several of the most important. Two-dimensional idealizations of store configurations were numerically analyzed to determine the initial behavior of pitch angle and vertical separation following release. Based on quasi-steady airloads, important characteristics of their trajectories are given for 17 combinations of system parameters. Trajectory calculations based upon unsteady airloads were made using three sets of parameters chosen for high, nominal, and low pitch oscillation frequencies (as compared with the results from the quasi-steady calculations). These unsteady airload results agreed fairly well in translational history with quasi-steady counterparts, but increasing frequency led to increased disagreement between the predictions of pitch behavior.

This book was released on 1993 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of the present investigation is to characterize the instantaneous flow field and force characteristics for a wing/fuselage/pylon/external store system during steady and unsteady flight. Emphasis is placed on practical. cost-effective engineering solution for the short-term treatment of the problem rather than an elegant mathematical modeling for the longer terms. Application of a Nonlinear Vortex Lattice Method (NVLM) Computational Fluid Dynamics (CFD) system with unsteady free wake formulation to obtaining flow field predictions about a maneuvering wing/pylon/store configuration is the primary objective of the current investigation. Separation the external store under the influence of unsteady wake roll up behind wing will be modeled by considering the full mutual interactions between the store and wing/pylon system in the second phase of the project. In this report, preliminary results were presented regarding the unsteady flow field below the wing about the external store and the unsteady aerodynamic forces on the external store before the separation during flight maneuvers. The validation of the computer modeling approach for the maneuvering wing/pylon/store combination needs experimental data. Unfortunately, the comparison experimental data were not available for the current research configuration and conditions. The experimental unsteady wing flow field and stability derivatives literature data was considered as the basis to test the accuracy and effectiveness of the computer code.
