FARNBOROUGH, England, July 16 /PRNewswire-FirstCall/ — FARNBOROUGH AIR
SHOW — Sikorsky Aircraft has chosen Hamilton Sundstrand to supply the
Utility Management System (UMS) for the CH-53K heavy lift helicopter, which
is under development for use by the U.S. Marines. Sikorsky and Hamilton
Sundstrand are both subsidiaries of United Technologies Corp. (NYSE: UTX).

“We are delighted to be a major supplier to Sikorsky’s CH-53K
helicopter program,” said Joe Triompo, president, Hamilton Sundstrand
Engine & Control Systems. “Our UMS will strengthen the aircraft’s data
management and subsystem control capabilities.”

The UMS includes two different digital electronic computers, designed
and developed by Hamilton Sundstrand. The computers manage air vehicle
inputs for key CH-53K helicopter subsystems.

Hamilton Sundstrand was previously selected to supply the CH-53K
helicopter’s secondary power systems — consisting of the environmental
control system, auxiliary power unit and main engine start system. The
company also was chosen to develop the helicopter’s fly-by-wire flight
control system, which includes triple redundant computers, and main and
tail rotor actuators. This system further builds on Hamilton Sundstrand’s
triple redundant fly-by-wire system designed for Sikorsky’s UH-60M
helicopter.
