Class Information
Number: 244/12.1
Name: Aeronautics > Aircraft, heavier-than-air > Airplane and fluid sustained
Description: Aeronautical machines having provision for sustentation in part or entirely by aerodynamic action on airfoils in fixed relation to the machines, having also provision for the sustention by the reaction to the downward movement of restricted masses or jets by air or other fluid, the forward propulsion of the machines may also be derived from movement of the same or similar masses or jets of air or other fluid.
