Reason of stalling at wing tip first
- outer wing has high AOI (Angle of Incidence) and thus experiences a higher aerodynamic loading
- in case sweepback design, more span-wise flow and
thus effective AoA (α e) ↓ as well as overall lift ↓
Result (Problem) of stalling at wing tip first
- in case sweepback wing, stalling at the wing tip first
- cause the center of pressure (CP) moves inboard and forward
- produces a pitch-up tendency
HOW to fix? – Designs to induce wing root stalling first
When sweepback is combined with low aspect ratio, it results in flying qualities very different from a more conventional high aspect ratio airplane configuration. Such airplanes require very precise and professional flying techniques, especially at slow speeds.
WHY rectangular wing is better as a basic training aircraft?
Using C172 as an example, rectangular wing has a tendency to stall at wing root first.
Then, what is the benefit?
