Bennekers, B. Zwaan, R.J. Institution National Aerospace Laboratory NLR Date 1975-05-12 Abstract A description is given of a panel method for the calculation of the aerodynamic loading on harmonically oscillating wing-body configurations in subsonic flow. Neglecting their thickness, the loading on the lifting surfaces is assumed to be generated by a distribution of unsteady lifting lines The loads on the body are represented by an unsteady source panel distribution. A way is indicated to introduce the effect of the steady flow field into the unsteady calculations. The method provides local and total coefficients as well as detailed pressure distributions on both the lifting surfaces and the bodies. The applicability of the method is shown in a comparison of calculated and experimental pressure and load distributions on a wing-tip tank-pylon-store configuration, To reference this document use: http://resolver.tudelft.nl/uuid:6622083f-159a-499d-b818-e2badde98846 Publisher Nationaal Lucht- en Ruimtevaartlaboratorium Access restriction Campus only Source NLR MP 75013 U Part of collection Aerospace Engineering Reports Document type report Rights (c) 1975 National Aerospace Laboratory NLR Files PDF 75013.pdf 8.48 MB Close viewer /islandora/object/uuid:6622083f-159a-499d-b818-e2badde98846/datastream/OBJ/view
