Lockheed Martin (Stand 1975) is installing its WindTracer windshear and turbulence-detection system at Dubai International Airport (DXB), where it will be used to detect aircraft wake vortices, thus allowing for increased runway utilization. Two WindTracers have been installed this year and a third one is to follow in the first quarter of next year, Michael Margulis, WindTracer program director, told AIN. WindTracer is a long-range, 3-D-scanning pulsed doppler lidar-based system.
What turned out to be a big week for Boeing with the formal launch of its new 777X widebody also promises to be a big week for the engine that will power it, the GE9X. Dubai Airshow visitors can get a sneak preview of the 102,000-pound thrust turbofan through a new 3-D representation of the equipment at the GE Aviation exhibit (Chalet A9).
Snecma is about to carry out further tests on a one-fifth scale model of an open rotor engine, in a research and technology effort that epitomizes how laborious developing a new commercial engine concept can be.
The FAA published updates to the wake turbulence separation categories on October 22 for Louisville, Miami, Cincinnati, San Francisco, Atlanta and Philadelphia airports based on improved understanding of how wake vortices behave. Categories are now based on weight, certified approach speed and wing characteristics. Special consideration will be given to aircraft with limited ability to counteract adverse rolls.
Among the operational topics for the technical committee at the triennial ICAO Assembly were significant safety issues. One paper from the Russian delegation provided a description of extensive studies of wake vortices, and the development of a wake vortex safety system that would use outputs from ADS-B, Swim and two Aviation System Block Upgrades 1 elements, with pilot alerts transmitted over the anticipated datalinks in that period–that is, by 2018.
Pilatus Business Aircraft is displaying a mock-up of its twinjet PC-24, announced earlier this year at EBACE, here at its NBAA booth (No. C12216) near the indoor static display. A prototype is currently under construction and is expected to fly late next year and certification and first customer deliveries are anticipated in 2017. Three aircraft will be used in the flight test program.
French engine manufacturer Snecma has been selected as the sole powerplant supplier for the new Dassault Falcon 5X, which was unveiled earlier this week here in Las Vegas. The new Silvercrest turbofan, rated at 11,450 pounds of thrust at takeoff and with a thrust-to-weight ratio of five, is expected to be certified in 2015. It will be the culmination of a 10-year effort, as Snecma began considering designing its first business jet engine in 2005.
The firm started in 1999 as the HVLS Fan Co., an acronym for high-volume low-speed fans. That name accurately described the design and efficiency of the company’s products, but after three years in business, according to the Lexington, Ky.-based manufacturer, “we finally had to bow to the sentiments of our customers and concede that we do, in fact, design and manufacture some Big Ass Fans.” Hence, the current brand name.
If you already fly or maintain some regional airliners and larger business jets, including the Bombardier CRJ200 and Global Express; Gulfstream IV and V/550; Dassault Falcon 2000EX and 7X; Embraer ERJ 145, 170 and 190; IAI Westwinds and Beechcraft King Air turboprops, you may already be familiar with an innovative, on-wing engine-cleansing system called EcoPower Wash.
Reno, Nev.-based Aerion is releasing results from recent flight tests of a natural laminar flow (NLF) wing test article this week here in Las Vegas, while the company continues to work to have its supersonic business jet enter service in 2020. The goal of these tests was to measure “real-world robustness” of supersonic NLF, which is a key technology for the Aerion SSBJ, in regards to surface quality and manufacturing tolerances.
