ABSTRACT:
The invention is a nose-torquer electromagnetic pulse deicing system for airfoil surfaces. A deflection wave mode deformation is generated in the skin (14) by activation of two electromagnetic coils (42). The coils (42) form part of a nose-torquer mechanism (40) which includes cantilever levers (46) and (47). The cantilever levers (46) and (47) are secured to the nose-section (44) of the airfoil. The coils (42), when electrically activated, cause a torsional wave deformation of the skin (14) as a result of opposite relative rotation between the levers (46) and the lever (47) about the nose-section (44).
