Class Information
Number: 244/11
Name: Aeronautics > Aircraft, heavier-than-air > Airplane and beating wing 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 flapping or reciprocating blades attached to the machines. These blades may also be the propelling agents.
