There has been discussion of a revised airfoil section and uprated Jabiru engines.
This was achieved by using a new type of airfoil section allowing high lift at low speeds without affect the cruising speed.
This is used to correct a problem with lift reversal in thick airfoil sections at low angles of attack.
The airfoil section was designed by Baynes and varied from the wing root outwards.
A fixed leading edge slot can increase the maximum lift coefficient of an airfoil section by 40%.
In an axial flow pump, blades have an airfoil section over which the fluid flows and pressure is developed.
It featured a lifting body of thick airfoil section between the inner engines.
The method has been automated so that complete pressure distributions for a given airfoil section can be obtained in a matter of seconds.
Hughes reluctantly concluded that the D-2 needed major modifications, including a complete redesign of the wings and a change in airfoil section.
The airfoil section used, the Eiffel 371 was something of a novelty, a thick wing with a quite flat bottom.
