Slide 9: Wing Sizing
Example: Typical wing input parameters and classic geometry WING SIZING relations Douglas DC-9 aircraft rigged to a test bench with key scalar variables used to define the geometry. This focus is to only change scalars that define the wing's geometry and observe the effect on the entire aircraft. Ch
Slide 10: Landing Maneuver
LANDING MANEUVER This example demonstrates the contact between wheels and the runway. Applying the brakes will affect airframe posture and load on the wheels. The aircraft system including landing systems is interesting for several analyses, such as behavior evaluation, controls validation, and syst
