#1897: FreightFoil

Today’s invention is a flying pallet which can be used by transport helicopters to move freight.

Such a system could help maintain an underslung load in a stable orientation.

Its main benefit however is that a wing of this kind will generate substantial extra lift when the helicopter is travelling forwards -as long as it’s far enough below the source of the downwash (and trimmed to the right angle of attack by altering the lengths of the suspension framework).

Although this is no help hoisting eg a shipping container off the ground, once in motion the wing could be made light and strong enough to reduce the loading on the main rotor, especially over long distances.
