    摘要: Electric current pulses separated by time intervals are transformed into mechanical power pulses acting on a surface to be de-iced. A converter of electric current pulses is constituted by a pair of electrically connected conductors one of which mates intimately with the surface to be de-iced. The conductors are arranged in the area to be de-iced and disposed one beneath the other. The electric current flowing through the conductors cause their mutual repulsion or attraction whereby electric current pulses are transformed into mechanical power pulses thus causing an elastic deformation of the surface being de-iced and effecting the removal of ice from this surface.

    摘要: A blade for a rotor of a hover-capable aircraft is described comprising: a main body with a first outer surface; and a de-icing system for removing ice; the de-icing system, in turn, comprises: a first layer formed by a shape-memory material activatable so as to alter its shape according to a temperature-associable quantity, which is arranged on at least one outer surface of the main body; the de-icing system is characterized in that it comprises a second covering layer, which defines at least a portion of a second outer surface of the blade on which ice deposits; the second layer laid on top of the first layer on the opposite side of the main body is selectively movable under the action of the first layer so as to exert a mechanical action on the ice and remove it from the blade, and is adapted to protect the first layer from external agents.

    摘要: Apparatuses for and methods of deicing aircraft surfaces, engine inlets, windmill blades and other structures are disclosed. Deicing apparatuses comprising at least one standoff coupled with an actuator and a first region of an inner surface of a skin are disclosed. A standoff can act as a moment arm and can create efficient, tailorable skin bending and acceleration, breaking an ice to skin bond. Integral as well as modular leading edges comprising deicing apparatuses are disclosed.

    摘要: A de-icing arrangement and method for de-icing a structural element. The 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 placed in relation to the structural element so as to apply a mechanical force caused by the expansion on the structural element. The capacitive storage bank includes a plurality of selectable capacitors of different size. The control unit is arranged to select at least one capacitor for charging having a size such that current discharge of the capacitive storage bank into the at least one electromagnetic actuator generates a desired distribution between heat and mechanical power.

    摘要: A de-icing system for a hemispherical protective housing mounted on an aircraft structure is described. The system can include a series of piezo-electric devices mounted at the boundary of the housing. The piezo-electric devices generate ultrasonic frequencies and resonance of the protective housing is induced. One of the piezo-electric devices senses the frequency generated in the protective housing and acts as part of a feedback loop to maintain structural resonance of the protective housing. The structural resonance of the protective housing prevents the build-up of ice. Additionally, higher power resonances can be generated to remove ice already built up on the protective housing. The system also enables detection of ice build-up on the protective housing by monitoring any change in the frequency required to maintain structural resonance of the protective housing.
