Why do wall-to-wall airfoils in wind tunnels produce no (or infinitesimal) downwash?
Any lift producing object always produces downwash. To achieve lift an object basically directs the airflow downwards. So there cannot be lift without downwash. Tip vortices might also be directed dow …

What are the dynamic stability properties of an aircraft with wings exactly at the vertical ...
In order for an aircraft to return to neutral roll the shape of the wings is an important factor as well and a number of other aerodynamic factors will play a role. A positive V-shape for example alwa …

How can we calculate the benefit gained from taping glider wing roots?
Based on what I have heard, the difference makes up for about 1 or 2 glide points.
I can imagine that this does also play an important role to interference drag between the fuselage and the wings. …

What are the benefits of a pivot wing?
The pivot wing and the variable sweep wing both enjoy the same benefits to any non variable wing design which is the ability to adjust the sweep angle and aspect ratio of the wing and the relative thi …

What is the relation between drag and weight?
It is hard to say what the ratio would be exactly.
Total drag consists of parasite drag and induced drag. The influence of angle of attack to parasite drag would depend largely on the aircraft design …
