Where would you find the leading edge on an airplane?
The leading edge of an airfoil surface such as a wing is its foremost edge and is therefore the part which first meets the oncoming air.
Are high lift devices on the leading edge of the wings to increase lift during low speed operations?
Slats are extendable, high lift devices on the leading edge of the wings of some fixed wing aircraft. Their purpose is to increase lift during low speed operations such as takeoff, initial climb, approach and landing.
What are the four high lift devices attached to an aircraft wing to provide lift?
The most common high lift devices are flaps, slats and Krueger flaps but the category also includes less common installations such as leading edge root extensions, which are found on high performance fighter aircraft, and boundary layer control devices inclusive of blown flaps.
How does the nacelle affect the wing lift?
Furthermore, decreasing the nacelle inclination led to higher lift curve slope values, which indicated that the powered wing could sustain higher angles of attack near maximum lift performance. Any lift augmentation was accompanied by a drag penalty due to the increased wing lift.
How is the lift coefficient of a wing increased?
Test results indicated that the lift coefficient of the wing could be increased by the propeller slipstream when the rotational speed was increased and high-lift devices were deployed.
What are the effects of the high lift system?
To isolate the effects of the high lift system, data were obtained with and without the flaps and leading-edge device. The effects of the propeller slipstream on the overall longitudinal aerodynamic characteristics of the wing-propeller assembly were examined.
How does the slipstream affect the aerodynamic characteristics of a wing?
The effects of the propeller slipstream on the overall longitudinal aerodynamic characteristics of the wing-propeller assembly were examined. Test results indicated that the lift coefficient of the wing could be increased by the propeller slipstream when the rotational speed was increased and high-lift devices were deployed.
