Bell Helicopter has chosen Texstars (Booth No. 507) to provide birdstrike-resistant windshields for the Bell 525 Relentless. These windshields will feature other safety improvements including enhanced pilot’s field-of-vision and a wrap-around windshield that eliminates the need for lower-view chin bubble windows and overhead skylights. The improved pilot’s view will enable direct sighting of mission objectives and landing zones.
Current in-flight icing detection systems (FIDS) cannot detect ice crystals. But equipment manufacturer Zodiac Aerospace (Booth E07) is developing a new FIDS, using optical techniques. It will detect any form of icing and will be able to tell which form of ice–small or large supercooled droplets, crystal and so forth–is impacting the aircraft. It will give the crew specific warnings when large-droplet icing conditions or ice crystals are encountered, François Larue, head of research and technology of Zodiac’s Aircraft Systems division, told AIN.
Researchers are gradually coming to understand the physics of in-flight engine icing due to ice crystals. In response to this enhanced knowledge of the subject, civil aviation authorities, such as the European Aviation Safety Agency (EASA) and the U.S. Federal Aviation Administration (FAA), are considering more stringent certification requirements.
GKN Aerospace (Chalet B73, Hall 2b F169) has completed coordination of a nine-nation European project, which has succeeded in developing a new optical ice-monitoring concept. The new system promises fully automated inflight ice protection for the first time.
Aviation thrives on innovation, and Aerospace Technologies Group of Boca Raton, Fla., and Aviation Glass & Technology in the Netherlands are doing exactly that.
ATG is a leader in the design and manufacture of aircraft window treatments and shades, and Aviation Glass recently introduced a 1.7-mm clear glass that is up to 25-percent lighter than the typical 3-mm polycarbonate currently in use. The two companies formed a partnership and expect to “conquer new frontiers with its revolutionary glass solution.”
Despite the first day of spring being just a few weeks away, encounters with icing at altitude still represent a very real problem. Responsibility for understanding the intricacies of ice formation, as well as how to exit an area of icing before a loss of aircraft control occurs, still falls on the cockpit crew. Here are some valuable icing resources that are easily accessed from any Internet connection that are worth bookmarking for next year’s season.
Many cockpit crewmembers believe the ingestion of ice crystals by a jet engine is essentially harmless if the engine’s igniters are turned on. However, aeronautical engineers generally do not agree, citing incidents when mixing ice with standard intake air resulted in a noticeable reduction in engine power output and, at its worst, a complete engine flameout. Ice formation inside an engine compartment can also lead to indicator anomalies that may not shut down the engine, but may lead to air data system failures.
Polycast UV-SC is the latest addition that Spartech has made to its growing product line of structural transparencies targeting the aircraft, mass transit, automobile and architectural markets. Polycast embodies the technology to produce cast acrylic sheet in a variety of colors that block significant amounts of ultraviolet (UV) light and the near-infrared solar energy’s heat radiation while maintaining high visible light transmission.
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.
Timco Aerosystems’ new dynamic sled test facility in Wallburg, N.C., has received FAA approval for the testing of aircraft seats to show compliance with regulatory codes 14CFR25.562 and 14CFR23.562. The approval enables Timco to test seats for compliance with critical occupant safety impact standards, including 16-g horizontal and 14-g vertical structural thresholds.
