Abstract
An ice protection system for a vehicle is disclosed which includes a plurality of de-ice power distribution units positioned proximate to a leading edge surface of the vehicle that is susceptible to ice accretion, at least two anti-ice power distribution units located within the vehicle, spaced from the de-ice power distribution units, and a point of power regulation located within the vehicle, spaced from the power distribution units, from which power is fed to the power distribution units through independent feeder wire bundles so as to distribute line current across the system in a manner that optimizes wire weight.
Claims15
An ice protection system for a vehicle comprising:
- a) a plurality of de-ice power distribution units positioned proximate to a leading edge surface of the vehicle that is susceptible to ice accretion;
- b) at least two anti-ice power distribution units located in a conditioned environment within the vehicle, spaced from the de-ice power distribution units;
- and
- c) a point of power regulation located within the vehicle, spaced from each of the power distribution units, from which three-phase AC power is fed to each of the anti-ice power distribution units through independent feeder wire bundles, and from which three-phase AC power is fed to the plurality of de-ice power distribution units through another independent feeder wire bundle, so as to distribute line current across the system in a manner that optimizes wire weight.
An ice protection system for an aircraft comprising:
- a) a plurality of de-ice power distribution units positioned within an engine nacelle of the aircraft;
- b) at least two anti-ice power distribution units located within the fuselage of the aircraft, spaced from the engine nacelle;
- and
- c) a point of power regulation located within the fuselage of the aircraft, spaced from the at least two anti-ice power distribution units, from which three-phase AC power is fed to the de-ice power distribution units within the engine nacelle and to the anti-ice power distribution units within the fuselage.
A method of distributing power to an ice protection system of an aircraft in a manner that optimizes wire weight comprising the steps of:
- a) accessing a point of power regulation in the fuselage of the aircraft;
- b) feeding three-phase AC power from the point of power regulation to a plurality of de-ice power distribution units located proximate to a leading edge surface of the aircraft that is susceptible to ice accretion, though a first feeder wire bundle;
- and
- c) feeding three-phase AC power from the point of power regulation to at least two anti-ice power distribution units located within the fuselage of the aircraft, spaced from the de-ice power distribution units, through respective independent feeder wire bundles.
