UCAV technologies pose new challenges for flight testing, including safety and security.

Boeing moves into development of the Active Parallel Actuator Subsystem to enable Chinook helicopters to be flown to their performance limits while improving safety and reducing wear and tear on components.

The HIFiRE program is designed to explore the fundamental science of hypersonic flight and pave the way for future generations of high-speed propulsion systems, vehicles and weapons.

I am fortunate that flying in unusual or novel aircraft comes with the territory in my job, but my latest assignment to visit the ‘big three’ engine makers for our May 23 propulsion special was noteworthy for the sheer variety of types flown over a short span of days.

Aviation Week's Guy Norris recently had the opportunity to fly on General Electric's newest flying testbed, a former JAL Boeing 747-400 based at the company's Victorville Flight Test Operations in California.

The engine-maker is using the latest in supply-chain methodologies and assembly line design to meet its production goals.

For big production increases, including for the PW1000G, Pratt is investing in manufacturing initiatives such as “intelligent” or automated production cells and advanced materials.
