Kestrel Aircraft has tapped Cox to supply an electro-mechanical ice protection system for its single-engine turboprop, the companies announced today at the NBAA Convention. The system allows “effective ice removal” without the need for de-icing boots or an anti-icing fluid system. According to Kestrel president and CEO Alan Klapmeier, the electro-mechanical system “allows for effective ice removal while retaining a laminar flow.” The single-engine Kestrel is expected to be in service by 2016.
CenTex Aerospace received FAA STC approval for its Halo 250 conversion for King Air 200s today. The conversion raises the mtow for 200-series King Airs from 12,500 to 13,420 pounds and moves the turboprop twin into the commuter category. Included in the Halo 250 conversion are new safety systems that provide improved stall warning in icing conditions, aural over-speed warning, elevator out-of-trim warning, engine fire extinguisher capability, emergency cabin lighting and illuminated escape path floor markings.
With fall approaching in the northern hemisphere, the FAA has issued Notice 8900.196, a revised document offering updates to the agency’s deicing program for the coming winter flying season. The update includes holdover times as well as a list of deicing and anti-icing fluids.
Canada’s National Research Council (NRC) has added new capabilities to its altitude icing wind tunnel (AIWT), such as simulating flights at 25,000 feet and the addition of hot air supply for models that use it for de-icing. The improvements will help NRC meet client demands for development and certification work recognized by regulators such as Europe’s EASA and the U.S. FAA.
Canada’s National Research Council (Hall 4 Stand C18B) has been flight-testing its Dassault Falcon 20 fueled by biofuel while sampling the exhaust using a probe fitted to a Lockheed T-33 chase plane. The NRC believes the exercise to be a world first.
Kilfrost (Hall 4 Stand G4) is introducing what it claims to be the first aircraft de-icing fluid made from sustainable sources. The new corn-based DF Sustain fluid is an environmentally friendly alternative to monopropylene glycol and it has already been approved by aviation authorities in the U.S. and Japan.
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.
On an unused corner of James A. Richardson International Airport in Winnipeg, Manitoba, a massive structure has emerged, the newest test cell in GE Aviation’s stable.
As the investigation continues into Tuesday’s fatal crash of a Daher-Socata TBM700 in New Jersey, more details of the flight’s final moments are emerging. According to the NTSB, the pilot reported that he was “picking up ice” just before the single-engine turboprop crashed into the treed median of I-287 near Morristown, killing all five on board.
