FARNBOROUGH AIR SHOW, FARNBOROUGH, England, July 14
/PRNewswire-FirstCall/ — Hamilton Sundstrand’s suite of systems has
contributed to the successful completion of Power On testing on for the
first Boeing 787 Dreamliner. Hamilton Sundstrand is a subsidiary of United
Technologies Corp. (NYSE: UTX).

Completed on June 19, Power On is a series of tests that verify
electrical power distribution and use in the real airplane environment, and
demonstrate installation of systems is correct.

“Hamilton Sundstrand is very pleased to have helped Boeing achieve this
milestone on the 787 program,” said Geoff Hunt, vice president of Hamilton
Sundstrand’s 787 programs. “Several of our 787 systems employ new aerospace
technologies, and we are proud of their performance in achieving Power On.”

Hamilton Sundstrand’s Airplane Power System Integration Facility
(APSIF) in Rockford, Illinois, U.S.A., played a pivotal role in developing
and testing multiple systems for the 787. Through high-speed data links
with Boeing and with other Hamilton Sundstrand facilities in Connecticut
and California, the facility operates as a virtual workspace. Engineers
from Hamilton Sundstrand test and verify systems in a real-time,
collaborative environment with other 787 partners, often thousands of miles
apart. Hamilton Sundstrand has completed more than 8,500 hours of
integration testing in the APSIF.

Among the nine system packages that Hamilton Sundstrand provides for
the Dreamliner, is the first electrically driven Environmental Control
System (ECS), which provides complete airplane thermal management and
enough efficient cooling capacity to cool more than 25 homes. The ECS
controls cabin and cargo cooling and heating, pressurization, and liquid
cooling for the power electronics.

Hamilton Sundstrand’s APS 5000 Auxiliary Power Unit (APU) provides
power to the 787 while it is on the ground, and in-flight back-up power.
The APS 5000 APU is rated at 1,100 shaft horsepower and is designed to
start and operate throughout the full range of the 787 operating envelope
up to 43,000 feet — all while operating 50 percent quieter and emitting 10
percent lower emissions than the Boeing 767 APU.

In the extremely rare condition of total power loss, the Hamilton
Sundstrand Ram Air Turbine (RAT) deploys from the underside of the fuselage
to produce power for the cockpit and flight controls, enabling the airplane
to land safely. Hamilton Sundstrand is the world’s leading supplier of
RATs. Since the technology’s inception, Hamilton Sundstrand RATs have saved
more than 1,600 lives.

The 787 is the first passenger airplane designed with an integrated
on-board Nitrogen Generation System, which produces nitrogen-rich airflow
to the fuel tanks to increase fuel tank safety. Hamilton Sundstrand
produces the pack assembly, including the motor-driven compressors.

Hamilton Sundstrand also provides the 787’s full suite of electric
power systems, including the Electrical Power Generation and Start System
(EPGSS), which generates and controls the airplane’s electrical power, and
starts the APU and main engines. The 787 is the first airplane to
incorporate electronic starting of a large turbofan engine. The EPGSS
incorporates other key technologies that enable the 787 to be the first
“more electric” commercial airplane. Comprising four main engine-mounted
variable frequency starter generators and two APU-mounted auxiliary starter
generators, the EPGSS system produces 1.450 megawatts of electrical power,
which is five times the power generation capacity of the 767 and enough to
power 400 homes. The system’s motor controllers are multiplexed to drive
the cabin air compressors, electric motor pumps and other power equipment
aboard the 787.

With 2007 revenues of $5.6 billion, Hamilton Sundstrand employs
approximately 19,000 people worldwide and is headquartered in Windsor
Locks, Conn. Among the world’s largest suppliers of technologically
advanced aerospace and industrial products, the company designs,
manufactures and services aerospace systems and provides integrated system
solutions for commercial, regional, corporate and military aircraft. It
also is a major supplier for international space programs.

United Technologies Corp., based in Hartford, Conn., is a diversified
company providing high technology products and services to the building and
aerospace industries worldwide.
