Induced Drag Reduction in Exact Coherent States of ...
The present work examines the effect of polymer additives on these "exact coherent states" (ECS) in the plane Poiseuille geometry, using the FENE-P constitutive model for polymer solutions, focusing on Reynolds numbers slightly above ...

Equation 14-10 facilitates an understanding and appreciation of induced drag.
Flight at high coefficient of lift conditions, such as low speed or maneuvering flight
, will create high induced drag whereas high speed, low C, flight will create low ...
Minimizing Induced Drag with Washout For a wing of any given planform shape
having a fixed washout distribution, induced drag can be minimized with washout
as a result of the trade-off between the second and third terms in the numerator ...

As it retards motion and increases fuel consumption, it also affects range,
endurance and maximum speed. In order of priority, drag can be split up into
various components: • Induced Drag. Sometimes called Vortex Drag or Lift
Dependent Drag ...

w/b This equation illustrates that, for given flight conditions, the span loading W/b
determines the induced drag. WAKE DRAG is caused by the boundary layer and
regions cf separated flow. The main source cf. drag generated by the boundary ...

The Elements of Aerofoil and Airscrew Theory
The determination of the induced drag of a biplane system is simplified by Hunk's
equivalence theorem for stagger*, which states that the total induced drag of any
multiplane system is unaltered if any of the lifting elements are moved in the ...
Induced drag The lift produced by an aerofoil has its reaction in the downward
momentum which it imparts to the fluid as it flows over the section. The lift of the
section is equal to the rate of transport of downward momentum of the fluid. A
drag ...

Variational Analysis and Aerospace Engineering
Aldo Frediani and Guido Montanari Abstract In 1924, Ludwig Prandtl published a
fundamental paper in which he showed that the lifting system with minimum
induced drag is a box wing. The re- sults were obtained through an approximate
...

Genetic Algorithms in Engineering Systems
Since the induced drag becomes one half to two thirds of the total drag during
climb, reduction of the induced drag is an important goal for the three-
dimensional wing design. According to the incompressible flow theory, the
minimum induced ...
