The US Navy has awarded aftermarket contracts to UTC Aerospace Systems in support of its Bell-Boeing V-22 Osprey programme.

As part of the awarded contracts, the company will perform constant frequency generator (CFG) repairs and retrofits, and also deliver upgraded spares for the aircraft.

UTC Aerospace Systems’ Military Programs, Power, Controls & Sensing Systems general manager Steve Hilliard said the CFG upgrades enhance the product while delivering a high return on investment for the US Naval Supply Systems Command (NAVSUP).

Featuring electric power systems, the V-22 CFG is comprised of a constant speed drive, generator and a generator control unit, which are integrated into a single line replaceable unit.

Designed to perform multiple missions with long-range, high-speed cruise performance, the V-22 Osprey features both vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) capabilities.

Powered by twin Rolls-Royce AE 1107C-Liberty engines, the aircraft is armed with an M240G 7.62mm machine gun and TK AN/AAR-47 missile warning system.

"V-22 Osprey features both vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) capabilities."

The upgrade programme, intended to enhance the CFG reliability and improve its overall aircraft operational readiness, is a joint effort by the US Naval Air Systems Command (NAVAIR), Boeing, Bell, NAVSUP Weapon Systems Support and UTC.

As a single source of support on the CFG application for the V-22 programme, the company’s total aftermarket contracts received to date are valued at $70m.

In September 2011, the company received an initial contract for the supply of kits to NAVSUP Weapon Systems Support Philadelphia, in support of the V-22 CFG Loss of Lube retrofit with a period of performance of 20 months.

The company also received delivery orders from the Defense Logistics Agency, Philadelphia, to provide CFG spares for the US Air Force, the US Navy and Marine Corps team.
