ESSENTIALLY the Autogiro consists of a fuselage that is propelled more or less horizontally through the air by an ordinary engine and propeller combination and wings that possess at least one degree of freedom with respect to the fuselage and turn around a central axis of rotation that is approximately perpendicular to the longitudinal axis of the fuselage, being articulated to a central hub and free to flap within rather wide limits. The present machines also have two small low monoplane fixed wings, that act mainly as supports for the ailerons, a fixed tail, elevator, fin and rudder.
Among the advantages claimed for the Autogiro are perfect stability, great flexibility, great adaptability, safety and the possibility of landing and taking off in a restricted area. The author claims that it is superior to the airplane for almost every purpose and is particularly adapted to civil aviation uses such as passenger transport, night mail service and especially for private flight.
