Abstract
Simulations are presented for 1:20 and 1:11 scale configurations of an advanced civil transport designed to use boundary layer ingestion (BLI). Comparison with wind tunnel results on unpowered configurations show that the computed and measured lift slopes agree within 15% and the drag at simulated cruise point to within 20%. Computations have been carried out for an initial and a redesigned configuration of the aft section of the aircraft. The redesigned version showed a reduction in lift and an increase in drag compared to the initial design. The mechanical power for a 1:11 powered configuration at cruise, without BLI, has also been calculated.
