Hybrid Doublet Lattice/Doublet Point Method for Lifting Surfaces in Subsonic Flow
A hybrid unsteady lifting surface theory combining the best features of the traditional doublet lattice method and the more recent doublet point method has been developed. The hybrid code will handle unequal strip widths and nonparallel intersecting lifting surfaces and retains most of the computational efficiency of the doublet point scheme. The application of the hybrid code to test cases shows an increase in computational efficiency in comparison to a comparable doublet lattice code with no degradation in accuracy.
