Summary

The vortex lattice model developed in Part I has been extended to estimate the overall loads and moments on a cylindrical nacelle alone and on a cylindrical nacelle, enclosing an engine, when the configuration oscillates in simple harmonic motion in an air stream. Results are presented for a range of frequency parameter and thrust conditions. Although the problem is properly posed for low speed flow through the ‘engine’, there is doubt over the model formulation when density changes need to be accounted for.

Type
