| Mar 24, 2020 at 16:03 | comment | added | Konrad | Thank you, one last question. Is the bound vortex a cause of lift generation? Because if we assume it as an airflow around a wing, so logickly no airflow around the wing means no lift | |
| Mar 24, 2020 at 13:27 | comment | added | JZYL | @Konrad Re your sec question: it depends on the fidelity of your modeling as mentioned in the post. If it's a lifting line, then the flow field from the circulation would only be very approximate, but good enough for lift estimation. If it's lifting sheet, then it gets better. If it's lifting surface, then even better. | |

| Mar 24, 2020 at 13:04 | comment | added | Konrad | And is bound vortex equivalent tu flow over and under the wing if we ommit vortices that leave the wing (tip vortices and starting vortex)? | |
| Mar 24, 2020 at 12:51 | comment | added | Konrad | Okey, thank you! But on your picture you replaced lift vector by bound vortices, and the lift equation from KJ theorem that you pasted include circulation. Is this circulation just bound bortex or whole circulation - bound vortex and tip vortices? And is bound vortex the cause of lift, no bound vortex, no lift? | |
