Boeing reported the first flight of the X-48C blended wing body (BWB) research aircraft at Edwards AFB on August 7. The unmanned 8.5-percent scale model reached 5,500 feet during a nine-minute flight. A week later, however, the company’s third X-51 Waverider hypersonic testbed flight ended in failure when its scramjet failed to ignite.

The Italian aviation safety agency, ANSV, issued four recommendations on August 2 to the EASA and Transport Canada about the Pratt & Whitney Canada PW127 turboprop engine that powers the ATR 72 regional airliner. The recommendations came after a series of engine failures that all occurred during the initial climb.

GE Aviation Systems is looking to rename its integrated vehicle health monitoring system now that it is ready to see it enter service. The product has a launch application on an undisclosed business jet and is also being evaluated by prospective airline clients. “This turns unscheduled events into scheduled events and could save roughly $8 billion for the industry,” said president and CEO Lynn Bolsinger.

UK-based Reaction Engines has carried out a series of tests on a key component for its new engine, the Sabre, which is capable of operating as both a jet and a rocket engine by employing a translating intake. The novel feature will enable the aircraft–such as the Skylon reusable spaceplane–that the Sabre will power to fly anywhere on earth in less than four hours or directly into space and back to deliver satellites or cargo.

General Electric is stepping up studies to provide a new engine for Boeing’s planned 777X. GE90 program manager Bill Millhaem has confirmed that the proposed GE9X turbofan will deliver 10 percent greater fuel efficiency than existing engines in the family.

The U.S. engine maker expects to achieve a first run of the high-pressure compressor rig early in 2013. The first test of the full core should be achieved by 2015.

S.S. White Technologies (Hall 4 Stand A4) has been selected to provide flexible rotary shafts for the Pratt & Whitney PW1000G engine’s nacelle. The shafts will transfer power on the variable area fan nozzle (VAFN) and synchronize actuators on the thrust reversers. The U.S. company has already provided two flexible rotary shafts for the thrust reverser rig, and previously supplied two flexible shafts for the VAFN test setup.

Pratt & Whitney Canada (P&WC) and GE Aviation are working on new-generation turboprop engines for the 90-seat regional aircraft that may be launched in the coming years. While P&WC is studying a clean-sheet design, dubbed Next-Generation Regional Turboprop (NGRT), GE is planning on a derivative of the GE38 turboshaft: the CPX38
