AviationGlass & Technology (Booth 1675), a first-time NBAA exhibitor, offers a certified mirror and optical lens that may change the face of aircraft interior design.

The two-year-old Netherlands-based manufacturer of optically true mirrors and lenses has been finishing its AS9100 paperwork with the goal of EASA certification of its products this fall. AviationGlass & Technology has installed the products in a Dassault Falcon 900 testbed. Typical applications include interior windows, bulkhead mirrors, lavatory glass (showers, for example) and mirrors, and so forth.

Safe Flight Instrument of White Plains, N.Y., has developed an aircraft-based icing conditions detector (ICD) system using a combination of optical detection and a shielded temperature probe. The optical system uses an LED, a prism and an infrared sensor to detect the presence of moisture in the air.

Icing is one of aviation’s major hazards and one that has been a causal factor in numerous accidents. Between 1982 and 2000, it was instrumental in more than 550 accidents that resulted in over 800 fatalities. While the lift- and controllability degrading effects of ice accretion on flying and control surfaces are well known, the ability to detect icing as it occurs has been a more difficult issue.

An international field research campaign led by Airbus and NASA has gathered a wealth of data on icing conditions in convective weather, especially on ice crystals that cause engine icing. The eight-week effort ended in March in Darwin, Australia, and the researchers expect to publish their report early next year. The partners in the project hope to gain a better understanding of icing conditions that will allow them to devise mathematical models for equipment manufacturers to use when designing detection systems.

Scientists in the propulsion system laboratory (PSL) at NASA’s Glenn research center in Cleveland, Ohio, have developed a test facility that can recreate high-altitude engine icing, a long-awaited capability that should equip the aviation industry to tackle a poorly understood hazard.

Over the last 20 years, the aviation industry has documented more than 200 incidents in which turbofans have lost power during high-altitude flights, according to NASA.

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.

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.

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.

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.
