Слайд 5 SPLIT FLAP

SPLIT FLAPIt is a part of the lower surface of the

surface of the wing trailing edge, the upper surface

contour being unaffected when the flap is lowered.

Слайд 6 SPLIT FLAP
LIFT.
The split flap gives about the same

SPLIT FLAPLIFT.The split flap gives about the same increase in lift

increase in lift as the plain flap at low

angles of attack but gives slightly more at higher angles as per upper surface camber is not increased, and so separation is delayed.
DRAG.
The drag, however is higher than for the plain flap due to increased depth of the wake.

Слайд 7 SLOTTED FLAP
When the slotted flap is lowered, a

SLOTTED FLAPWhen the slotted flap is lowered, a slot or gap

slot or gap is opened between the flap and

the wing.

Слайд 8 SLOTTED FLAP
PURPOSE to direct higher pressure air from the

SLOTTED FLAPPURPOSE to direct higher pressure air from the lower surface

lower surface over the flap and re-energise the boundary

layer. This delays the separation of the airflow on the upper surface of the flap.
LIFT gives a bigger increase in lift then the plain or split flat
DRAG much less drag

FOWLER FLAPMoves rearwards and then down, initially giving and increase in

and increase in wing area and then an increase

in camber.

Слайд 10 FOWLER FLAP
LIFT Because of the combined effects of an

FOWLER FLAPLIFT Because of the combined effects of an increased area

increased area and camber, the Fowler Flap gives the

greatest increase in lift of the flaps considered.
DRAG The least drag.

Слайд 12 LEADING EDGE HIGH LIFT DEVICES
There are two forms

LEADING EDGE HIGH LIFT DEVICESThere are two forms of leading edge

of leading edge high lift device commonly in use:

the leading edge flap and the leading edge slot or slat.

Слайд 13 KRUEGER FLAP
The Krueger flap is part of the

KRUEGER FLAPThe Krueger flap is part of the lower surface of

lower surface of the leading edge, which can be

rotated about its forward edge.

Слайд 14 VARIABLE CAMBER
LEADING EDGE FLAPS
To improve efficiency by giving

VARIABLE CAMBERLEADING EDGE FLAPSTo improve efficiency by giving a better leading

a better leading edge profile, the camber of a

leading edge flap may be increased as it is deployed.

Слайд 15 LEADING EDGE SLOT
A leading edge slot is a

LEADING EDGE SLOTA leading edge slot is a gap from the

gap from the lower surface to the upper surface

of the leading edge, and it may be fixed, or created by moving part of the leading edge (the slat).

Слайд 16 LEADING EDGE SLAT
A slat is a small auxiliary

LEADING EDGE SLATA slat is a small auxiliary aerofoil attached to

aerofoil attached to the leading edge of the wing.

When deployed, the slat forms a slot which allows passage of the air from the high pressure region below the wing to the low pressure region above it.

Слайд 17 AUTOMATIC SLOTS
On some aircraft the slots are not

AUTOMATIC SLOTSOn some aircraft the slots are not controlled by a

controlled by a pilot, but operate automatically. Their movement

is caused by the changes of pressure which occur around the leading edge as the angle of attack increases.

Слайд 18 SEQUENCE OF OPERATION

SEQUENCE OF OPERATIONThe leading edge device must be deployed prior to

deployed prior to the trailing edge flap is lowered.

When

the flaps are retracted, the trailing edge flap must be retracted before the leading edge device is raised.
