Improved Propeller De-Icing Systems

Diamond Antenna proposes to leverage our proprietary Roll-Ring® technology and create a roller-block Roll-Ring® assembly. This roller-block Roll-Ring® assembly will be a form, fit, and function replacement for the brush block assembly presently used in the propeller de-ice slip ring. This roller block assembly will interface with the current ring (rotor) assembly. The roller-block employs the same rolling electrical interface presently used in Roll-Rings®. At the end of phase II, including the phase II option, the delivered hardware will be available for flight tests. Phase II has a 6-month duration and will produce a form, fit, and functional, roller block assembly. This assembly will operate at the maximum rated speed of 1106 rpm and the rated current of 54 amps. This roller block assembly will be tested to operate at the rated current and speed. Life testing will be started on this assembly. Then the customer will authorize continuation to the Phase II option. During the phase II option, Diamond Antenna will build and qualify a roller block assembly. At the end of the phase II option, Diamond Antenna will deliver three flight-worthy Roll-Rings®.
