Boeing Enhances Chinook with New Engines and Block II Upgrades at $96 Million

Boeing delivered the first CH-47F Block II Chinook to support ongoing modernization efforts of the U.S. Army. The Army’s fleet will have up to 465 aircraft that will be converted to the new Block II configuration.

Up to 465 CH-47F Chinooks will be upgraded

According to Heather McBryan, vice president and programme manager for cargo programmes, “the CH-47F Block II provides capability improvements allowing the U.S. Army to lift more, fly farther, and maintain their aircraft better than ever before.”

“The battle-tested Chinook will now be able to play a significant role in multi-domain operations thanks to this modernization programme.”

The CH-47F Block II can carry practically all payloads for a greater mission radius and offers an extra 4,000 pounds of maximum gross weight because to its upgraded drivetrain, strengthened airframe, and improved fuel system. Furthermore to the capability improvements, the aircraft’s design enables future technology upgrades.

The corporation also enhances aircraft sustainment through its Block II programme. The fuel system has been simplified to increase sustainment efficiency and decrease maintenance expenses, while the new rotor system’s increased reliability helps to minimise unscheduled maintenance.

In order to meet the demands of Special Operations Command and the Army for a heavy-lift helicopter that can withstand higher altitudes, larger loads, and hotter temperatures, Honeywell’s most recent T55-714C turboshaft engines and Boeing’s Chinook Block II improvements will make the CH-47 more powerful than ever.

Boeing upgraded the drive train, strengthened the CH-47’s fuselage, rebuilt the fuel tanks, and made other changes for the Chinook Block II that will allow the fleet to operate at greater performance levels.

Enables carrying 22,000-plus pounds of payload.

With the engine performance upgrades, the 6,000 shaft horsepower will be a 22% improvement over the present T55-714A and a four-fold increase over the original T55 engine.

This implies that the Chinook Block II helicopter, equipped with the new Honeywell engine, will be able to carry more than 22,000 pounds of cargo, as opposed to the CH-47’s present capacity of roughly 20,000.

Moreover, a new compressor module in the T55-714C will result in 8% less fuel use and a 25% increase in overall reliability, including a 40% longer compressor life.
