Leading edge slats


#1

Has anyone heard about that 1935 plane, known for taking off on extremely short distances ?

Thre are a few ideas here for us , like those leading edge slats

Look for Fieseler 156

The idea is to warp the profile when taking off to minimize needed power to take off

This is how the RC world does it :slight_smile:

Interesting but difficult to implement. IMHO, implementing a flap (wing trailing edge) seems easier and less prone to jamming (weeds/algae for example) that would in turn create unwanted drag. The difficulty here is to avoid creating dirt traps.

Yep. But that is only for a few seconds. If I am not mistaking this plane can take off at 29 km/h…
