Power for the rescue

Boeing has selected Honeywell T55-GA-714A turbo shaft engines to power the HH-47 helicopter proposed for the US Air Force Combat Search and Rescue (CSAR-X) program.

“The Combat Search and Rescue program is an important initiative to flight crews and service people around the world,” said Mike Tkach, vice president of Boeing Rotorcraft Systems. “Honeywell engines on the HH-47 will provide the best possible performance for our aircraft to meet critical mission requirements.”

CSAR-X is a US Air Force initiative to procure more capable and survivable aircraft able to recover isolated personnel from hostile territory. The tandem rotor, heavy lift, high altitude HH-47 is based on the CH/MH-47 Chinook tandem rotor transport helicopter, with performance capabilities that have been widely demonstrated in international humanitarian relief operations.

The engines for the HH-47 are identical to the engines currently used on the Chinook helicopter and have been proven in the sand, heat and high altitude of Iraq and Afghanistan. Additional system features include inlet particle separators for longer life and an infrared suppressor for reduced aircraft signature.
