Aircraft wing layout

The canard layout is that the lift center of the wing is in front of the center of gravity of the aircraft, and at the same time, the tail is moved to the nose position to generate upward force to balance the pitching moment.

The traditional layout is that the lift center of the wing is still behind the center of gravity of the aircraft, but the tail generates downward force to balance the pitching moment.

The downward negative lift of traditional aircraft tail is equivalent to the increase of aircraft gravity, and the lift on the wing should overcome both gravity and the negative lift of tail. The forward movement of the canard tail generates upward lift. It's not easy to draw here. If the landlord still does not understand, you can continue to contact me. Duck layout is mainly used for fighter planes, and of course there are also civil aircraft with duck layout. As far as I know, F 16 is compatible with the traditional layout and canard layout, that is, at low speed, the tail generates downward negative lift, and the wing lift center is located behind the center of gravity to balance the pitching moment. At this time, it is a traditional layout. At high speed, the center of lift moves slightly before the center of gravity. At this time, the angle of attack of the tail becomes a positive angle of attack and begins to generate upward lift to balance the pitching moment. At this time, it is a duck layout. And the closer the center of gravity is to the center of lift, the better the maneuverability of the aircraft will be.
