Engine Designed To Enhance Performance For RQ-4 Global
Hawk
The growth variant of the Rolls-Royce AE 3007H engine has
successfully completed its US Air Force funded flight test,
according officials at the company. The engine is designed to
enhance performance of the RQ-4 Global Hawk unmanned aircraft and
will offer customers significant improvements in engine durability
and total life-cycle cost savings.

The engine, which improves both the turbine and fuel nozzles,
began development in 2008. Rolls-Royce made the announcement at the
annual Air Force Association Air & Space Conference, near
Washington, DC. The growth engine was tested in a Northrop Grumman
RQ-4 Global Hawk aircraft and both aircraft and engine performed in
line with expectations.
“This is another major milestone for a system which has
been flying for 13 years and amassed more than 60,000 flight
hours," said Stephen Fairbairn, Rolls-Royce, Vice President –
Customer Business. We continue to enhance our engine performance
and capabilities for our customers with these types of
improvements.”
The Block III enhancement provides significant increases to the
life of the turbine and nearly doubles its time on wing. It will
become the production configuration for US Navy MQ-4C Broad Area
Maritime Surveillance Unmanned Aircraft System (BAMS UAS) and the
US Air Force Global Hawk program, as well as future variants. The
RQ-4 is powered by a Rolls-Royce AE 3007H turbofan engine.
