It's all a matter of muscle power and lifting surfaces."

Remember that this only applies when it is hinged to a lifting surface.

Wings had already been studied extensively as the obvious lifting surfaces.

One way to reduce induced drag is to increase the aspect ratio of the lifting surface.

The fixed wing was put onto a flat, wide fuselage that also provided an effective lifting surface.

There's no suggestion of any lifting surfaces, either.

The lifting surface of the kite boomed and shivered.

This problem can be addressed by superposition of lifting surfaces through the experimental input option.

The lower wing had parallel chord and straight edges, providing a lifting surface with about 40% the area of the main plane.

Lift based wind turbine typically have lifting surfaces moving perpendicular to the flow.

Flat lifting surfaces are, however, never used.

Sometimes applied to the "tail-boom" framework connecting the tail-plane with the main lifting surface.

Such application is not quite correct, since "plane" indicates a flat surface, and the lifting surfaces are always cambered.

In canard aircraft, both fore and aft planes are lifting surfaces.

He was famous for building multiplane flying machines with many more sets of lifting surfaces than would be normal on modern aircraft.

The principle of a difference in the angle of incidence between the main lifting surface was worked out for the first time by Pénaud.

Heavy ribbed membranes like bat wings extended between the legs, giving enough lifting surface to support the beast in the air.

Instead, the pilot just grabs the lifting surface by hand (using a rigid frame that hangs from its underside) and moves it.

Compound rotorcraft may also include additional thrust engines or propellers and static lifting surfaces.

This unorthodox design consisted of a flat, somewhat disc shaped body (hence its name) serving as the lifting surface.

By itself, the fuselage provides approximately 40 to 60 percent of the F-14's aerodynamic lifting surface depending on the wing sweep position.

Such a craft could dispense with lifting surfaces, but would still need heat-resistant skin for hypersonic flight in the atmosphere.

In fact the designation "three lifting surface" may be considered as a variant of a "three surface" aircraft.

The tandem triple or tandem triplet configuration has three lifting surfaces one behind another.

Zimmerman's research also posited aircraft having flat circular bodies, sans wings, as their lifting surface.
