Engine enhancement

After several years of working closely with the U.S. Navy and Marines Corps, GE-Aviation has been awarded $1.4 million in initial funding to perform nonrecurring engineering work associated with the integration of an engine upgrade into the AH-1Z helicopter. Under this arrangement, GE-Aviation, as a subcontractor to helicopter manufacturer Bell, will ship three instrumented T700-401C flight-test engines from its Lynn, MA, facility later this year. The original AH-1W Super Cobra is powered by two GE T700-401 engines, and serves as the Marines Corps’ primary attack helicopter. Under the upgrade program, up to 180 existing AH-1Ws will be re-manufactured to the new AH-1Z configuration, transitioning from a two-blade rotor to a four-blade rotor powered by twin Lynn-built T700-401C engines, plus a new main gearbox and all new avionics.

Colorado-based Boom Technology’s “Baby Boom” XB-1 supersonic demonstrator—a one-third scale stepping stone to a supersonic 40-seat passenger airliner—will make its first test flight late-2017. Although currently under construction, the XB-1 is described as “the first independently developed supersonic jet and history’s fastest civil aircraft.”
The U.S. military recently announced that it has successfully tested a swarm of 103 autonomous Perdix micro-drones over the Naval Air Weapons Station at China Lake, CA. The drones operated as a group to complete four specific missions during the test sortie.
Uber announced a partnership with Aurora Flight Sciences to develop electric vertical takeoff and landing (eVTOL) aircraft for its Uber Elevate Network. Aurora’s eVTOL concept is derived from its existing XV-24A LightningStrike VTOL X-Plane subscale vehicle demonstrator aircraft.
Although the lightweight, supersonic T-38 has been the staple advanced jet trainer for the U.S. Air Force and U.S. Naval Test Pilot School for more than 55 years, the aircraft is expected to be replaced by a new trainer that can better transition pilots into fourth- and fifth-generation fighters.
