Abstract
In the present v/ork, the Integral equation method has been applied to calculate the pressure distribution over an arbitrary, three dimensional lifting wing and a three dimensional wing with an external store, kept beneath the wing. The present study gives a method to calculate the Interference effects Imposed by an external store on the wing and vice-versa. The wing alone transonic solution Is analyzed and compared with the experimental results and as well as a wing with an external store. A theory for the flow field nonlinear velocity prediction Is developed, programmed, and applied to a wing with an external store configuration and the flow field velocities are compared with the experimental results . The numerical methods for solving the triple and double Integrals with limits ranging from -∞ to +∞ are studied and the application of one such method to the flow field prediction problem Is briefly Indicated. Future extension of this work is indicated with the limitations and advantages.
