Bauhaus Luftfahrt, a Germany-based aerospace think tank, has outlined its vision of an electrically powered, emission-free airliner–relying on batteries–that it believes could be in service by 2035. The most obvious aspect of the design is a C-shaped wing for greater lift. Another major feature is the use of superconductivity for better power transmission and greater motor power density.
Skyscapes, a new basecoat/clearcoat exterior paint developed by Sherwin-Williams Aerospace, now has two complete coatings, including pretreatment, corrosion protective primer, topcoat and clearcoat. Both are certified with SAE International’s Aerospace Material Specification 3095 (AMS 3095). One system includes Alodine, 483987 primer and Skyscapes basecoat/clearcoat. The second system is Alodine, 483787 chrome hazard-free primer and Skyscapes basecoat/clearcoat.
The U.S. Air Force will gradually lift flight restrictions placed on its Lockheed Martin F-22 Raptor fleet in response to unexplained incidents of hypoxia, or oxygen deprivation, experienced by pilots dating as far back as 2008.
The FAA has issued an airworthiness directive for certain Bombardier Challenger 300s as a result of reports of deformation found at the neck of the pressure regulator body on the oxygen cylinder and regulator assembly (CRA). It requires an inspection to determine if a specified oxygen CRA is installed and to replace affected oxygen CRAs.
Russia’s VSMPO-AVISMA Corp., specialist manufacturer of products made of titanium and aluminum alloys, steel and nickel, and Shanghai Aircraft Manufacturing Co. (SAMC), have signed a long-term purchase contract for titanium forging products for the Comac C919 aircraft program.
A seven-month investigation by the U.S. Air Force Scientific Advisory Board into unexplained hypoxia, or oxygen deprivation, incidents experienced by F-22 pilots has not determined the root cause of the problem, the service said March 29. The investigation did produce a number of safety recommendations, and the Air Force continues to study the problem.
The photo of a badly burned Apple iPhone that circulated after the phone caught fire during a Regional Express flight has raised important questions about lithium-ion battery safety among a wide aviation audience. The incident occurred after the Regional Express Saab 340B landed in Sydney, Australia, on Nov.
With a narrower pipe but greater reach for voice and data than its rival Inmarsat, the Iridium satellite network is becoming increasingly relevant for aircraft cockpits.
The FAA has issued Special Conditions for the Cessna 680 Sovereign, for which Cessna proposes to use rechargeable lithium-ion main batteries and APU start batteries. According to the FAA, lithium-ion batteries differ significantly from the nickel-cadmium (Ni-Cad) and lead-acid rechargeable batteries currently approved.
The FAA proposed a civil penalty against the Massachusetts Institute of Technology (MIT) on September 2 for allegedly providing to FedEx a mislabeled box containing lithium batteries, bringing attention to an issue of particular concern to the airline industry.
