Anti-icing surfaces under development at GE and EADS could one day reduce and possibly even eliminate the need for existing anti-icing techniques. Research organizations at the two major aerospace companies are currently working on surfaces that would naturally repel ice without using energy.
GE Global Research presented new findings on nanotextured anti-icing surfaces and coatings last week at the American Physical Society Conference in Boston. While there are many applications for this technology, aircraft are at the top of the list.
Deliveries of the HondaJet will be delayed until at least mid-2013, because of a late-stage redesign of the aircraft’s GE/Honda HF120 engine. The engine fan has undergone a redesign following the failure of an on-ground ice ingestion test, Honda Aircraft president Michimasa Fujino revealed today at the NBAA Convention in Las Vegas.
The FAA has finally put a regulatory nail in the coffin of ice bridging with a new rule requiring Part 121 airline pilots to activate deicing systems at the first indication of ice accumulation.
Why some engines fail in flight is the subject of a new NASA research program. “There is a question regarding the effect that moisture has on newer-technology engines.
A contingent of U.S. Air Force flight attendants participated in this year’s NBAA Flight Attendants/Flight Technicians conference, not just to learn from their peers but to share their own experiences using dry ice as a cooling medium to keep food safe on long trips. It turns out that a sufficient quantity of dry ice allows for weeks of operation and proper food storage. There are important safety considerations when using dry ice.
The FAA’s Draft Advisory Circular 20-147A released last month provides new guidance to aircraft manufacturers on compliance with regulations covering engine induction system icing and engine installation ice requirements. Comments on the draft AC are due by November 1.
Eurocopter yesterday unveiled the X3 (“x cube”) demonstrator, a compound helicopter with a 220-knot cruise speed. The aircraft first flew on September 6 in hover, and is scheduled to fly again on Thursday. Some 100 flight-test hours are planned in the next 18 months, with the target speed expected to be reached in the first quarter.
The FAA yesterday issued Draft Advisory Circular 20-147A, which provides new guidance to aircraft manufacturers on compliance with regulations covering engine induction system icing and engine installation ice requirements. The new guidance will replace AC20-147A, which was last revised in 2004. Comments on the draft AC are due by November 1 and can be sent to the FAA's John Fisher.
Proposed changes to Parts 25 and 33 address dangerous icing conditions caused by supercooled large drops including a requirement that manufacturers not only show that airplanes can operate safely in those conditions but also with specific performance and handling qualities and that “all new transport-category designs be able to fly in co
