Class Information
Number: 244/9
Name: Aeronautics > Aircraft, heavier-than-air > Airplane and paddle wheel 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 sustentation or vertical lift by the downward thrust developed by rotating paddle wheels. These paddle wheels may also provide a part or all of the forward propulsion.
