    摘要： Systems and methods for modifying ice adhesion strength of ice adhered to an object. An electrode is electrically insulated from the object and a power source, e.g., a battery, is coupled to the object and the electrode. The source generates power to an interface between the ice and the object when the ice completes the circuit. The object is conductive or is doped as a semiconductor so that a voltage to the interface selectively modifies the ice adhesion strength. The strength can be increased or decreased relative to its static state (i.e., the state without applied voltage). Ice can, thus, be removed with less work. The system preferably includes an electrically insulating material disposed between the object and the electrode; the insulating material is substantially conformal to the object and the electrode. The invention also includes a ferroelectric material applied to power lines to melt or prevent ice formation.

    摘要翻译： 用于改变冰附着在物体上的冰粘附强度的系统和方法。 电极与物体电绝缘，并且电源例如电池耦合到物体和电极。 当冰完成电路时，源向冰和物体之间的界面产生电力。 该物体是导电的或被掺杂为半导体，使得界面的电压选择性地改变了冰粘附强度。 相对于其静态（即，没有施加电压的状态），强度可以增加或减小。 因此，冰可以用较少的工作去除。 该系统优选地包括设置在物体和电极之间的电绝缘材料; 绝缘材料基本上与物体和电极保持一致。 本发明还包括应用于电力线以融化或防止冰层形成的铁电材料。

    摘要： A plurality of electrodes in a solid object are located proximate to the contact interface between an ice layer and the surface of the solid object. A power source provides a potential difference across the electrodes to generate an electric field at the contact interface, thereby increasing the friction force between the solid object and the ice. Preferably, the power source is in AC power source. A capacitor in series between the power source and the electrodes creates an additional impedance for limiting the AC current to a level safe for human exposure.

    摘要： An apparatus for deicing an outer shell includes an element comprised of shaped memory metal which undergoes a transformation from a weaker low temperature form (Martensite) to a stronger, high temperature form (Austenite) when the element is heated through its transformation temperature. The change in shape is utilized to deflect the outer shell to thereby shed ice accumulated thereon.

    摘要： A deicing system for an aircraft engine (4) having blades (14, 16) fixedly attached to rotating propulsors (6, 8) has emitters (22, 28) which irradiate microwave beams (24, 26, 30 32) onto coatings (18, 20) which are fixedly attached to said blades (14, 16). Substantially more of the energy of the beams (24, 26, 30, 32) is absorbed by the coatings (18, 20) than by any water or ice on the blades (14, 16) causing any ice which is on the blades (14, 16) to be thrown off by the centrifugal force of the rotating propulsors (6, 8).
