Human Error

Later, Hutchins built on another of his own areas of skill and expertise, this time in aviation, to undertake studies involving the operation of large commercial jet aircraft. In making the approach and landing the aircraft must achieve certain speeds so that the appropriate configuration of wing flaps can be set. Flaps are physical extensions of the wing surface that can be extended and retracted allowing the aircraft to operate safely at different speeds. Higher speeds are required for efficient cruise and lower speeds are required for landing which must be made at a specific speed.

Flaps. Flaps are moving parts of the wing trailing edges located inboard (close to the fuselage), and belong to the secondary flight control system. Flaps are used to reduce the take-off and landing distances. When the airplane is taking off, the flaps help to produce more lift. Oppositely, flaps can provide a steep angle during landing. In this case, flaps are used to increase drag. Wing flaps change the shape of the airplane wing, by extending it (or retracting it) and providing the appropriate configuration for take-off, cruising, or landing.

Of course, the lift and drag performance is the primary factor which allows the aircraft to achieve its speed (cruise, landing, take-off), range, cruise altitude, and other top-level performance requirements. These functions are achieved through the aerodynamic shaping of the wing and various other external components. Most manufacturers are employing winglets to enhance the lift and drag performance. Flaps provide augmented lift and drag for landing. The airframe segment described in Section 9.8 bears the major responsibility for satisfying these functions.

The preliminary investigation process shows that the airflow pattern can be significantly modified by adding an obstacle into the chamber to deviate a certain part of the airflow that is stuck together due to the dynamic viscosity effect. The obstacle in the chamber plays almost the same role as the airplane flaps positioned at the wings’ trailing edges (Figure 5). Those flaps are used to increase the plane’s lift by deviating the air flowing through the wings.

The movement of the flaps is achieved through an actuator drive unit which drives the flaps along their inner and outer flap tracks from a retracted position at 0 degrees, through deployment angles of 10, 15, 20 and 37 degrees, as reported in Figure 3. The test specimen consists of the flap body and the flap-to-flap track interface components only, whereas, the test rig includes dummy tracks and flap-to-flap track interfaces.
