摘要： An electro-thermal or hot gas anti-icer of the "running-wet" type is mounted at the leading edge of an airfoil. Mechanical de-icers are mounted on the surfaces aft of the anti-icer. The mechanical de-icers throw off ice without creating runback water, thereby eliminating runback refreeze ridges caused by a known hybrid ice-protection system. Advantageously, the de-icers are of a type in which the airfoil has a semi-rigid skin that forms an aerodynamic surface of the airfoil, and in which there is at least one mechanical actuator for flexing the skin.

摘要： A pass network includes a switching element having a non-smooth conduction characteristic in the transition region about zero-crossover of an AC signal to be switched. A bypass network is connected in parallel with the pass network and has a smooth conduction characteristic in that transition region.
