Wing Flap Protection
Lowering a aircraft wing flap during maintenance or cleaning, exposes the corners of the flap and the fixed wing corner. The resulting sharp edge is dangerous!
There are many different designs of flaps, with the specific choice depending on the size, speed and complexity of the aircraft on which they are to be used, as well as the era in which the aircraft was designed. Plain flaps, slotted flaps, and Fowler flaps are the most common. Krueger flaps are positioned on the leading edge of the wings and are used on many jet airliners.
Extending the wing flaps increases the camber or curvature of the wing, raising the maximum lift coefficient or the upper limit to the lift a wing can generate. This allows the aircraft to generate the required amount of lift at a lower speed, reducing the minimum speed (known as stall speed) at which the aircraft will safely maintain flight. The increase in camber causes an increase in drag, which can be beneficial during approach and landing, because it slows the aircraft. For most aircraft configurations, a useful side effect of flap deployment is a decrease in aircraft pitch angle, which lowers the nose thereby improving the pilot’s view of the runway over the nose of the aircraft during landing. Another side effect however, depending on the type of flap, location on the wing and deployment speed during their extension, the flaps will more or less cause the indicated (or relative to the unchanged airfoil) angle of attack to lower within a short time due to an increase in nose down pitching moment which is characteristic to all trailing edge down as well as leading edge down flaps, then followed by a nose rise (pitch-up) due to the increase in lift, thus obscuring the pilot’s view of the runway if no action is taken over the pitch inputs.
Wing flaps are an amazing feat of engineering. There is a huge variety of wing flap designs on aircraft in use today. And we make covers to fit them all.
The exposed corners create a hazard to personnel.
Trisoft Aircraft Covers can eliminate this hazard. Simply slip the covers onto the corners of the wing flap and the fixed wing corner and you have created a safer work environment for your employees. See our product catalog for additional items to protect your planes and people!
