WebThe aircraft considered were a 125 foot diameter six-bladed rotor helicopter and an 85 foot diameter four- bladed rotor tilt rotor. The objectives were to reduce power required and increase maximum lift. The effects of improved airfoils and active controls were investigated. Airfoils with higher maximum lift and with reduced drag were investigated.

The case of cambered airfoils will be treated in Section 4.8.įor the time being, we deal with thin airfoils for such a case, the airfoil can ... WebAirfoils A helicopter flies for the same basic reason that any conventional aircraft flies, because aerodynamic forces necessary to keep it aloft are produced when air passes about the rotor blades. The rotor blade, or airfoil, is the structure that makes flight possible. Its shape produces lift when it passes through the air.
