Title:
HEATING DEVICE AND METHOD FOR DEPLOYABLE RAM AIR TURBINE
Document Type and Number:
WIPO Patent Application WO2002086298
Kind Code:
A3
Abstract:
The heating apparatus and method for the nose fairing of a rotating blade assembly has an electrical generator connected to a heating element attached to the interior of the forward end of the nose fairing. The electrical generator has a rotor with conductor windings attached to the aft end of the rotating blade assembly hub housing. The stator of the electrical generator is attached opposite the rotor on the support structure for the hub housing with stator magnets spaced from and opposite the rotor windings. When the hub housing is rotated by for example airflow through the blades of the rotating blade assembly the rotor moves relative to the stator thereby creating an induced current in the windings. This converts the rotational energy to electrical energy to power the heater to heat the nose fairing to inhibit the formation of ice thereon.
