  • Beam balancer electro-impulse deicing systems
    Patent number: 4501398
    Abstract: Torsional movement of a blade mass balance element (64) in a helicopter blade brings about a twisting of the upper and lower skin surfaces (24) and (26) of the blade (60) to produce a torsional travelling deformation wave in the skin. Torsion of the mass balance element (64) is accomplished through electrical activation and interaction of an upper coil (63) and a lower coil (62). The lower coil (62) is attached to the balance bar (64) via a cantilevered lever (66) while the upper coil (63) is attached to the balance bar (64) at two spanwise locations via a beam structure (68). The coils (62, 63), when electrically activated, cause torsion to be introduced into the mass balance element (64).

  • Nose-torquer electro-impulse deicing systems
    Patent number: 4458865
    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).

  • Staggered coil and nose-torquer electromagnetic pulse deicing systems
    Patent number: 4399967
    Abstract: The invention is a staggered-coil and nose-torquer electromagnetic pulse deicing system and process for deicing airfoil surfaces. A plurality of upper and lower electromagnetic impulse coils (18) and (20) are arranged in a staggered geometrical array spanwise of an airfoil or wing (22). The upper coils (18) are arranged adjacent to and spaced from the upper wing skin surface (24) while the lower coils (20) are arranged adjacent to and spaced from the lower wing skin surface (26) so that when the coils are activated a torsional wave mode deformation of the skin (14) occurs. In another embodiment, a deflection wave mode deformation is generated in the skin (14) by activation of two electro-magnetic coils (42). In yet another embodiment, torsional movement of a blade mass balance element (64) in a helicopter blade brings about a twisting of the upper and lower skin surfaces (24) and (26) of the blade (60) to produce a torsional travelling deformation wave in the skin.
