Parker Aerospace’s Nichols Airborne Division is here at NBAA to provide information about its bleed air valve new spare and factory-overhaul exchange program, along with its factory overhaul program on the Airborne brand of fuel pumps.
BEECH 1900D, ROCHESTER, N.Y., JUNE 3, 2000–The Safety Board determined probable cause for a gear-up landing by a CommutAir Beech 1900D during a regularly scheduled flight. According to the NTSB, “The reversal of landing gear hydraulic lines by company maintenance personnel [caused the failure].
Price Induction, a startup company based in Anglet, France, is studying a 560-lb-thrust high-bypass-ratio turbofan that would establish a new thrust class. Applications of the DGEN380 would be four-seaters, allowing pilots to upgrade from piston singles to twinjets. Another market could be airline-pilot training.
Spectrum Aeronautical (Booth No. 1947) has quantified the CO2 that will be generated by its Freedom S-40 and Independence S-33 business jets and compared those to competing jets to see how the Spectrum jets stack up emissions-wise. On a 600-nm flight, the midsize S-40 generates slightly less than 1,500 kilograms of CO2, according to Spectrum, while comparable jets should generate more than 2,000 kilograms to nearly 4,000 kilograms.
French engine manufacturer Snecma is developing a new high-pressure core for regional jet applications, dubbed DEM 21 for “21st century demonstrator,” in the 12,000- to 17,000-lb-thrust range. The program may provide the basis for variants capable of powering regional airplanes of up to 70 seats.
Pratt & Whitney Canada (Booth No. 463) now has two major new business aircraft powerplant programs underway, with Bombardier having just selected it to provide the PW308B turbofan for its new Learjet 85 model. Meanwhile, detailed design work has begun for the PW810 engine that will drive Cessna’s new Citation Columbus large cabin aircraft.
What presented the impetus for the PW810’s development?
When we started to talk about the PW800 family [in the late 1990s], we were talking about an engine for the next generation of regional aircraft.
A St. Louis-area maintenance facility is finalizing flight-test data required to support a Sabreliner 65 reduced vertical separation minimum (RVSM) compliance package. Avmats of Chesterfield, Mo., expects to receive group certification in October for Sabre 65s. The RVSM package includes replacement of the jet’s Collins ADC-80K air-data computer with new dual Collins ADC-87A air-data computers.
Last month NASA made the first flight of an experimental “wing warping” Boeing F/A-18 flying testbed. In 1903 the Wright Brothers used wires connected to their control column to twist the wings of their Flyer, changing the airfoils’ shape to provide differential lift to control bank. NASA calls the 21st century version of wing warping the “active aeroelastic wing,” or AAW.
Turbine-engine technology development is going in two directions. One is the development of new technology to push the envelope of performance, operational safety, maintainability and reliability. The other is to refine and update existing engines for long-term use, especially in light of more stringent Stage 4 requirements and existing Stage 3 rules.
