First, a change in rear lift leads to a great reduction in induced drag.
The discussion of drag reduction will illustrate the innovations of the British on external wire bracing drag, the French on cowl design and the Germans on cantilevered wings and induced drag.
These vortices produce what is called induced drag and are powerful enough to disrupt aircraft flying too closely to one anotherNone reason for the carefully monitored spacing between flights at takeoff and in the air.
Also being looked into is the installation of wing-tip winglets to reduce induced drag and thereby enable the aircraft to increase its operational ceiling, which will prove a significant advantage particularly for the AEW&C version mentioned above.
In normal cruise, the flaperons have a -5 degree position, which has the effect of reducing down force on the tailplane and sharply reducing induced drag enough to add several knots to the top cruise speed.
By altering the airflow as it Leaves the wingtip, the extensions reduce wingtip vortices and induced drag.
Wing drag was calculated as the sum of zero-lift drag, induced drag, wave drag, profile drag and interference drag.
Drag is commonly divided into 3 components: 1) profile drag, generated by friction; 2) induced drag, from the loss of kinetic energy in the wake, which is indissociable from the production of lift; and 3) the parasite drag, which is the drag of the body.
Also, the tips are tapered to reduce induced drag and power-robbing vortices.
