Performance and Stability of Aircraft
Theoretically, about the minimum is achieved by an untwisted wing with an
elliptic planfonn, and has a value given by c,,,, = -7: (1.9) The trailing vortex drag
for other planforms is obtained by multiplying this value by a factor (74035); ...

Theoretical Aerodynamics
The generation of these vortices requires a quantity of kinetic energy. This
constant expenditure of energy appears to the aerofoil as the trailing vortex drag.

Aerodynamics for Engineering Students
This drag force is the trailing vortex drag, abbreviated to vortex drag or more
commonly induced drag (see Section 1.6.7). A very descriptive name that is used
more frequently by pilots than by aerodynamicists is drag due to lift. Considering
for ...

Thus far we have talked about only two of drag's components (skin-friction drag
and pressure drag). Drag has a third component called vortex (commonly
referred to as induced or trailing vortex) drag, which is a direct result of the
generation of ...

THE CYCLIST'S MIND GOES EVERYWHERE
Time-trail bikes might have discwheels, which reduce spoke-drag. Normal
pressure drag includes form drag, induced trailing vortex drag (more applicable
to aircraft wings) and wave drag. Non-streamline bodies, e.g. cyclists, mainly
cause ...

... foil at high speed can be determined as a function of the angle of attack solely
from two-dimensional wind tunnel data. A theory for the trailing vortex drag was
developed for both deeply submerged and surface-piercing dihedral hydrofoils.
There are many contributions to the total drag of an aircraft, the chief ones being
trailing-vortex drag, profile drag (comprising surface friction drag and form drag)
and wave drag (including separation). Trailing-vortex drag A major source of ...

4.21 The variation of drag with speed for a typical light aircraft Note how the
trailing vortex drag reduces with increasing speed while the boundary layer drag
rises. The resulting total drag therefore has a minimum. Flying slower than the ...
