The X-45C configuration is scaled to the SACCON’s wingspan, evaluating forces, moments, surface pressure, and vortex dynamics. The SACCON configuration experiences pitch-up at 16°, while the scaled X-45C displays no pitch-up. The cranked-segment geometry of the X-45C optimizes spanwise pressure gradients, and delays vortex breakdown, thereby mitigating pitch-up.
