L.E. flaps-do they work?
I understand the difference very clearly. Here are some examples for you:
Slots (on leading edge of stabilator)
McDonnel Douglas F-4E
Slats
North American F-100
L. E. Flaps
McDonnell Douglas F-4
In contrast the McDonnell Douglas F-15 has a fixed leading edge because of the type of airfoil used for the wing. The McDonnell Douglas F-18 also has a fixed leading edge because the fuselage is a part of the wing as is the SU 29.
