This paper presents computational study of transonic wing-strut interference effects of the Mach 0.8 Transonic Truss-Braced Wing (TTBW) aircraft using the high-fidelity CFD solver FUN3D. The study is conducted for the wing-strut and the wing-alone configurations at design Mach number0.8 and Reynolds number14.0 ́106.The interference effects are calculated by comparing the wing aerodynamics along the spanwise direction between the wing-strut and the wing-alone configurations. The presence of the strut underneath the wing induces a suction peak on the lower surface of the wing, which causes changes in aerodynamic forces and moments. The interference effects of the Mach 0.8 TTBW aircraft are compared with the Mach 0.745 TTBW aircraft. A transonic wing-strut interference aerodynamic correction model is developed for use in a lower-fidelity tool, VSPAERO, for rapid aerodynamic analysis of the Mach 0.8 TTBW aircraft.
