Based on the cross-sectional figure provided, which type of trailing edge high-lift device is illustrated?
Refer to figure.
Trailing edge high-lift devices (flaps) are used to increase wing lift coefficient at low speeds during take-off and landing by increasing camber, chord, and in some cases wing area.
Several flap types are used in aviation, each with different high-lift characteristics and mechanical complexity (see figure).
The plain (simple) flap rotates downward about a fixed hinge at the trailing edge, increasing camber without changing wing chord or area.
