Smith, Lelanie; Craig, K.J. (Kenneth); Meyer, Josua P.; Spedding, G.R. (American Institute of Aeronautics and Astronautics, 2019-01)It is common for new aircraft configuration proposals to include some kind of lifting body. The reduction in fuselage–wing interference drag, in principle, improves span efficiency and hence allows for reduction in total ...
