Goodrich Innovations Enable Greener Aerospace Industry
Reductions in noise, emissions and fuel burn enhance environmental sustainability
CHARLOTTE, N.C., Feb 17, 2008 /PRNewswire-FirstCall via COMTEX News Network/ -- (Singapore Airshow)--
Technological innovations from Goodrich Corporation (NYSE: GR) in lightweight
composites, structural design and engine fuel components are key enablers that
help customers meet future environmental requirements.
"While 'being green' is currently the fashion for industry in general, it
has been a way of life for Goodrich and the aerospace industry since day one,"
said Harry Arnold, vice president of technology for Goodrich. "Economics and
the environment are linked in our business; our customers have the task of
building and operating aircraft that consume the least fuel while carrying the
maximum payload, and to do so safely and cleanly. We work relentlessly to
reduce weight, enhance aerodynamics and improve fuel efficiency on all
products and services across the enterprise."
The majority of noise from aircraft is generated from the engine by fans,
compressors, and from jet mixing. As a primary designer and manufacturer of
nacelles, Goodrich engineers reduce noise through dispersion, dampening,
absorption and frequency change. Acoustics specialists continue to find new
ways to manufacture quieter systems, reducing noise during take off and
landing as well as noise in the interior cabin throughout flight. Carbon-
based composite materials, 10 times stronger and three times lighter than
steel, are used to mold the outer shell of the engine nacelle. These advanced
nacelle systems absorb engine energy, aiding in significant noise reduction;
their light weight enhances fuel economy.
Carbon dioxide emissions are directly related to fuel burn, and fuel burn
is directly related to weight. While reducing component weight is one way to
reduce fuel burn and its attendant emissions, the future demands even more
creative solutions. Goodrich is at the forefront of leading edge research and
technologies in this area, such as fuel burn optimization.
For new engines, efficiency can be increased by raising the pressure and
temperature in the engine core during the combustion process. This, however,
increases nitrogen oxides (NOx) emissions, a common pollutant. By tracking
physical and acoustic aspects of the combustion process, Goodrich engineers
are enabling engines to operate at higher temperatures by burning leaner while
avoiding problems with instability; these hotter, more efficient engine cycles
have the added benefit of eliminating much of the carbon byproduct and NOx of
the combustion process, resulting in reduced emissions. Goodrich researchers
have developed specialized audio and optical sensors that identify
instabilities by actually listening to and viewing fuel burn; high speed
valves and control logic can then properly adjust fuel flow. Continued
development is getting this technology out of the lab and into the real world
environment. A complementary collaboration with Iowa State University is
focused on detection and control of thermoacoustic instabilities generated
Elsewhere, Goodrich is partnering with a multi-company/university team,
led by Rolls-Royce, on a research project dubbed the Environmentally Friendly
Engine (EFE) technology program. Goodrich's Engine Control and Electrical
Power Systems team, headquartered in Birmingham, UK, is Rolls-Royce's largest
partner on the program and will be providing the next generation of electronic
and fuel system controls for a number of engine technology validation runs
over the course of five years.
Changes on the horizon include engines that emit 20 percent less carbon
dioxide and 80 percent less NOx, and reduce noise by 18 decibels. "Reducing
weight, fuel burn and drag, without compromising safety or performance, is our
continuous improvement quest. The better we are, the more we help our
customer achieve their green goals," Arnold said.
Goodrich Corporation, a Fortune 500 company, is a global supplier of
systems and services to aerospace, defense and homeland security markets.
