dc.description.abstract A method of calculating stability derivatives for wings oscillating at low frequencies is developed from the modified vortex-lattice method outlined in R. & M. 2470. Derivatives are obtained for the following wings describing plunging (vertical translational) and pitching oscillations: (i) Delta wings of aspect ratio A, = 1.2, 2 and 3 with a taper ratio 1/7. (ii) Arrowhead wing of aspect ratio 1.32 with a taper ratio 7/18 and angle of sweep of 63.4 deg at quarter chord. (iii) Circular plate. Comparison is made with measured values of the derivatives for the delta wing of aspect ratio 1.2 and the arrowhead wing oscillating in incompressible flow. Satisfactory agreement is obtained with experiment, and also with values calculated by the Multhopp-Garner method 4. en_US
