vortex dragに関する本と英語文献で使われた文脈を提供するための簡単な抜粋文。
The additional drag resulting from any change of lift coefficient from the datum
value is regarded as lift-dependent drag. The three components of datum drag
shown in Figure 3.1, viscous drag, wave drag and vortex drag, all refer to the
datum ...

Computational Mathematics Driven by Industrial Problems: ...
Since the vortex drag can be reduced simply by reducing the lift, the lift coefficient
must be fixed for a meaningful drag minimization. In order to do this the angle of
attack a is adjusted during the flow solution. It has proved most effective to make
...

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); ...

Road and Off-Road Vehicle System Dynamics Handbook
Instead of the term “induced drag,” “vortex drag” is used in vehicle aerodynamics.
Due to the interaction between the vehicle and the road surface, rotating wheels
and the cooling air intake flow, etc., the minimum drag does not occur at zero lift ...

This process requires energy, and the energy that has to be expended to
maintain the tip vortices is a component of the drag the lifting foil incurs as it
passes along, called vortex drag (DJ. It is not hard to guess that as the tip vortices
depend on ...
... so excellent is the streamlining. When the mackerel swims, however, some part
of the vortices trailing in its wake arise from the generation of thrust and lift, so
that this second vortex drag component is an inevitable consequence of these ...
