Te primary function of flaps is lift augmentation. Flaps are located at the trailing edge of the wing as well as on the leadind edge. we will discuss about the leading edge flaps.
Flaps at the leading edge can be:
1. Slats
2. Leading edge flaps
The purpose of both are same but they are diffent in there mechanical design as well as there location at leading edge of the wing.
Leading edge flaps are present under the leading edge i.e they are inboard and when they are actuated, they expand from the bottom surface and become the leading edge. Actually they throw more flow at the top. so greater flow from the top, results higher lift. leading edge flaps are not the part of the wing.
On the other hand Slats are present at the top of leading edge and when they are actuated they appear from the top and become the leading edge of the wing. Slats are the part of the wing. They are cambered so that when they are displace from the top the wing remain cambered and they become leading edge.
some good diagram explanig them are:
If you have any question please feel free to ask.. thank you

Thanks for this clear and concise discussion point, very helpful!
ReplyDeleteI AM NOT OVERLY DUMB BUT I AM STRUGGLING WITH WHICH WAY A RAISED FLIGHT SURFACE CAUSES A PLANE TO GO DOWN OR UP..AND V.VERSA...E.G, ON LANDING, ARE THE FLAPS IN AN UP OR DOWN CONFIGURATION...THANKS AND SORRY FOR SUCH AN OBVIOUS LAPSE IN MY COMMON SENSE...LOL
