| 1. | However the aircraft always stalls at the same critical angle of attack.
|
| 2. | A swept wing has a lower, flatter curve with a higher critical angle.
|
| 3. | The critical angle is normally measured by looking through a telescope.
|
| 4. | Symmetric airfoils have lower critical angles ( but also work efficiently in inverted flight ).
|
| 5. | We did an experiment in class to find out what the critical angle of glycerol is.
|
| 6. | There is an easy way to check this critical angle without having to measure distances or lengths.
|
| 7. | Digital refractometers also find the critical angle, but the light path is entirely internal to the prism.
|
| 8. | The critical angle can be calculated using;
|
| 9. | The critical angle of attack in steady straight and level flight can be attained only at low airspeed.
|
| 10. | As speed reduces, angle of attack has to increase to keep lift constant until the critical angle is reached.
