Former DOT Inspector General Mary Schiavo’s law firm, Motley Rice LLC, has filed suit against Bombardier, General Electric, Honeywell, Northwest Airlines, KGS Electronics and Parker Hannifin on behalf of the families of the pilots who died in the crash of a Pinnacle Airlines Bombardier CRJ200 on Oct. 14, 2004, near Jefferson City, Mo.
European engine manufacturers are joining forces on Vital, a research program co-funded by the European Commission that aims to reduce carbon dioxide (CO2) and noise emissions by commercial aircraft.
In an effort to save weight and improve reliability, Honeywell has asked its engineers to develop systems that will replace traditional aircraft hydraulic and bleed-air systems with all-electric architecture. The U.S.
Never before has commercial air transport come under such scrutiny for its environmental impact. While aircraft have made far more progress in terms of reducing fuel consumption and emissions per passenger carried in recent years, the relentless overall growth of air traffic has led to increasing pressure from the environmental lobby to reduce the noise and emissions produced by modern powerplants.
Airbus has chosen Honeywell’s HGT1500 auxiliary power unit (APU) to provide electric and pneumatic power for the new A350 variant of the A330 twin-aisle airliner, while Boeing has selected the company’s nitrogen-generation system (NGS) for the single-aisle 737.
Pratt & Whitney has announced upgrades to both its venerable JT8D engine and the PW4000 high bypass ratio turbofan. Improvements to the JT8D are aimed at enabling the engine to meet the latest ICAO Chapter 4 noise rules, which took effect in January. A noise-reducing kit will, says the company, provide a solution to operators of MD-80s wishing to avoid landing charges levied because of excessive noise.
Pratt & Whitney’s efforts to ensure it takes pole position in the next generation of medium-sized powerplants are materializing, with several major technology programs under way aimed at ensuring its geared turbofan (GTF) demonstrator beats the competition.
Manufacturers should be required to determine if engine restart capability exists after high-power, high-altitude flameouts, according to the NTSB. For airplanes susceptible to engine core lock, manufacturers should be required to provide design or operational means to ensure restart capability.
The news that Snecma is working on the new 8,500- to 10,000-pound thrust SM-X engine to power new large business jets and regional airliners hasn’t shaken Pratt & Whitney Canada (P&WC). Nor has last month’s suspension by Bombardier of the 110- to 135-seat C-Series twinjet program.
Both China’s J-10 fighter and the Indian air force Bakhadur MiG-27ML fighter bomber are set to be re-engined with two new variations of the Russian Salyut AL-31FN engines–the AL-31FN M1 and the 99-3, respectively.
