Among the exhibitors making their debuts at NBAA’s annual showcase is Pulsar Informatics (Booth No. C12047), which is demonstrating its new crew fatigue evaluation web application: the Aviation Fatigue Meter. According to the Philadelphia-based company, the app can be used for every kind of business aviation operation, no matter the scale or complexity, and it is described as an “easy way for people to see how any particular schedule is impacted by human fatigue factors.”

The National Business Aviation Association (NBAA) will offer a webinar on fatigue this Wednesday, September 25, from 1 to 2 p.m. EST. Called “Understand How Fatigue Can Affect Your Department’s Performance and Safety,” the session will provide background on the science behind fatigue risk management systems (FRMS) and fatigue modeling, as well as offer a streamlined version of FRMS that fits the business aviation market. The webinar is free to NBAA members.

Elliptical Mobile Solutions (EMS) has launched Zero Shock Seating (ZSS), a spinoff company that is expected to “dramatically improve comfort, safety and overall performance” for various modes of transport, including aviation.

ZSS is a startup company based in Chandler, Ariz., with exclusive rights to negotiate ownership of a patented, semi-active suspension system. The technology substantially eliminates shock experienced by passengers in all vehicles by automatically adapting to both the driver’s body weight and changing levels of shock and vibration.

The FAA issued a notice of proposed rulemaking to revise an existing airworthiness directive for the AgustaWestland AW139 requiring inspection of the fuselage frame to detect fatigue cracks that could lead to structural failure and subsequent loss of control. Since the AD was issued, AgustaWestland developed a frame reinforcement modification that supports extending the interval for inspecting the fuselage frame for a fatigue crack.

The National Research Council of Canada (NRC) announced a two-year collaborative research agreement with the Japan Aerospace Exploration Agency (JAXA) on June 19 to carry out widespread fatigue damage assessment for the JAXA curved fuselage panel tests. The partnership is considered a cost-effective way to study widespread fatigue issues on an aircraft’s main pressure vessel. The tests are ultimately designed to improve air safety by creating evaluation technology capable of maintaining the structural integrity of new and aging civilian aircraft.

MBDA’s high-energy laser weapon uses highly sensitive, four-channel mirror optics to track targets and adjust the laser beam.

MBDA Germany is claiming a world’s first in the development of high-energy laser weapons after coupling together four commercially available 10kW-industrial lasers to achieve a 40kW weapon that can intercept and destroy incoming rockets, artillery and mortars (RAM). Small aerial vehicles, such as UAVs, are also on MBDA’s target list, but the company says power supply challenges still preclude adding lasers to aircraft for defensive purposes.

AgustaWestland’s AW189 medium twin can run for 50 minutes after loss of gearbox lubrication, a condition that has caused several incidents among large transport category helicopters recently.

Loss of lubrication to the main gearbox (MGB) has been responsible for several crashes, ditchings and precautionary landings in large transport category helicopters in recent years. These accidents set off broad debate as to exactly what is required of main gearboxes under Part 29 certification of the U.S.

Aerometals has received PMA approval for spiral bevel gears for the main rotor transmission of the MD500. According to the company, the approval marks the first time the FAA has granted manufacturing approval for transmission gears to a company that is not the OEM. The testing required a test stand using a 500-hp electric motor instead of a gas turbine. The MD transmission is rated for 425 hp for up to five minutes, but Aerometals ran the gears for eight hours at 467 hp to satisfy FAA testing requirements.

Former U.S. Air Force pilot Sean Gillette announced yesterday the launch of a new “personal jet” program, the Saker S-1, a twin-engine two-seater capable of flying 1,600 nm and cruising at Mach 0.95. With twin vertical fins, tandem seating and short fighter-like wings and stabilizer, the S-1 brings to mind the Aviation Technology Group Javelin.

A Gulfstream G650 set a city-pair speed record last month on a flight between Shanghai and Newark, N.J., flying the 6,855-nm route in 13 hours and 32 minutes, the Savannah, Ga.-based aircraft manufacturer announced yesterday. The jet took off from Shanghai Hongqiao International Airport on April 18 carrying five passengers and four crewmembers. ATC restrictions kept the G650 below FL310 for the first hour before it was cleared to climb to its normal cruising altitude of FL410 to FL510.
