    摘要: A de-icing arrangement and a method for de-icing a structural element. The de-icing arrangement includes at least one electromagnetic actuator, a capacitive storage bank, a control unit arranged to provide an excitation pulse to the at least one electromagnetic actuator, and a charging circuit arranged to charge the capacitive storage bank. The at least one electromagnetic actuator is arranged to expand in at least one direction when fed with the excitation pulse. The at least one electromagnetic actuator is arranged in relation to the structural element so as to apply a mechanical force caused by the expansion on the structural element. The control unit is arranged to control cutoff of current discharge of the capacitive storage bank into the at least one electromagnetic actuator so as to abort the excitation pulse at a predetermined timing after start of the excitation pulse.

    摘要: An electro-active polymer (EAP) surface (10) having a plurality of actuators (20) adapted to prevent the formation of ice on an external surface (230), such as a leading edge of an aircraft (100). The EAP surface (10) may also be adapted to remove ice formed on the external surface (260). The actuators of the EAP surface (10) may be oscillated to prevent and/or remove ice from the surface of an aircraft (100). A signal generator (30) may be used to individually oscillate the actuators (20) in a first mode to prevent the formation of ice(230) and a second mode to break up ice formed on the EAP surface (10). The signal generator (30) may oscillate all of the actuators (20) at the same frequency, may individually oscillate the actuators (20) to form a pattern on the EAP surface (10), or may individually oscillate the actuators (20) to form a wave along the EAP surface (10). The actuators (20) may be dimple actuators, wrinkle actuators, and/or bump actuators.

    摘要: An airfoil (100) comprises a skin (110), comprising an external surface (112) and an internal surface (114), opposite the external surface (112). The skin (110) is magnetically and electrically conductive. The airfoil (100) also comprises an interior space (108), formed by the skin (110). The internal surface (114) faces the interior space (108). The airfoil (100) additionally comprises a leading edge (106) along the external surface (112). The airfoil (100) further comprises a hybrid acoustic induction-heating system (102), configured to impede formation of ice on the external surface (112). The hybrid acoustic induction-heating system (102) comprises an induction coil (130) within the interior space (108). At least a portion (136) of the induction coil (130) is sufficiently close to the internal surface (114) to produce an eddy current (180) in the skin (110) when an alternating electrical current (134) is flowing in the induction coil (130). The hybrid acoustic induction-heating system (102) also comprises at least one magnet (140) within the interior space (108). At least the one magnet (140) is configured to produce a steady-state magnetic field (182) within the skin (110).
