  2. Normal Force • Model scales Normal force with both Mach Number and Angle of Attack Inputs • Pitching Moment and Axial Force (Drag) vary similarly • Center of Pressure at α = 0 is at roughly 39% of the length from the nosetip, for all three cases Figure by Alex Woods and Jayme Zott

  3. Structural Forces • Shear Forces are less than expected using the current model • For all models, transonic values are at best a guess, due to model inadequacy Figure by Alex Woods and Jayme Zott

  4. References • Ashley, Holt, Engineering Analysis of Flight Vehicles, Dover Publications Inc., New York, 1974, pp. 303-312 • Anderson, John D., Fundamentals of Aerodynamics, Mcgraw-Hill Higher Education, 2001 • Jayme Zott for substantial assistance in troubleshooting and integrating the code, as well as tabulating results
