Aboard
fuel-efficient aircraft, inside quieter jet engines, or atop more
efficient air traffic control towers, NASA is with you when you fly.
Holiday Season Makes Most of NASA Aeronautics Gifts
Temperatures are dropping, the leaves are falling, and the countdown is
on to the busiest time of year for air travel around the nation.
The industry association Airlines for America predicts 24.6 million
passengers will take off to visit friends and family during the upcoming
Thanksgiving holiday weekend, up 1.5 percent from 2013. Sunday, Nov.
30, will be the busiest day of the year at U.S. airports.
Even if you won’t be taking to the sky anytime soon, it’s a good bet
something you're using today– your cell phone, flat-screen TV – or the
holiday gifts you're buying online arrived as part of the billions of
tons of cargo shipped on airplanes every year in the U.S.

The holidays reinforce how much
we rely on aviation.
And thanks to advancements in aeronautics developed by NASA, today’s
aviation industry is better equipped than ever to safely and efficiently
transport all those passengers and packages to their destinations.
“It is absolutely true that
every U.S. aircraft flying today
has NASA-developed technology incorporated into it in one way or
another,” said Jaiwon Shin, NASA’s associate administrator for
aeronautics.
Streamlined aircraft bodies, quieter jet engines, techniques for
preventing icing, drag-reducing winglets, lightweight composite
structures, and so much more are an everyday part of flying thanks to
NASA research that traces its origins back to the earliest days of
aviation.
It’s the same story for the U.S. air traffic control system. Computer
software tools produced by NASA to help reduce congestion from gate to
gate, on the airport tarmac and along the highways in the sky, are in
place at Federal Aviation Administration facilities all over the
country.
“That’s why we like to tell people that NASA is with you when you fly,” Shin said.

Contributions to aviation pre-date NASA
NASA’s commitment to leadership in aeronautical innovation dates back to March 3, 1915, when the
National Advisory Committee for Aeronautics – or the N-A-C-A – was formed in response to concerns the U.S. was losing its edge in aviation to war-torn Europe.
Just 12 years after the Wright Brothers’ first heavier-than-air
flight, as World War 1 raged overseas, the U.S. Congress created the
NACA in part to “supervise and direct the scientific study of the
problems of flight with a view to their practical solution.”
Subsequent research by the NACA’s engineers at its world-class
laboratories and wind tunnels led to fundamental advances in aeronautics
that enabled victory in World War II, propelled supersonic flight,
supported national security during the Cold War, and laid the foundation
for the space age.
Although the NACA in 1958 became NASA, which assumed responsibility
for space exploration, its tradition of aeronautical research endures:
identifying ever more complex problems in aviation and providing
practical solutions using ever more sophisticated tools.
NASA has made decades of contributions to aviation.
Research energized by a vision and an anniversary
Guided by a fresh strategic vision that organizes NASA’s aeronautical research into
six new strategic thrust areas,
and inspired by the upcoming centenary of the NACA's founding, the next
100 years of innovation and ingenuity will begin with ongoing efforts
to design new aircraft and engines that burn less fuel, operate more
quietly, and generate fewer emissions.
At the same time, working with its industry and government partners,
NASA also will continue to improve and modernize the nation’s air
traffic control system so it can safely handle the two times or more
increase in air traffic expected in the future.
NASA research highlights scheduled to take place during the NACA centenary year include:
- Testing of a large composite structure called "PRSEUS" that was
manufactured using a new technique that shows promise for making major
aircraft components stronger, lighter and less susceptible to damage
than composite material now in use.
Flight
tests are taking place now of a shape-changing trailing-edge wing flap
that could improve aerodynamic efficiency and reduce noise generated
during takeoffs and landings.
- Flight tests of a trio of technologies on Boeing's ecoDemonstrator Program,
including a new air traffic control tool that promises to increase
capacity along approach paths to an airport and potentially reduce
passenger delays; a system for blowing compressed air across the surface
of an aircraft’s vertical tail that could allow engineers to someday
design smaller aircraft tails that reduce drag and save fuel; and
coatings designed to reduce turbulent flow over a wing by preventing
insect residue from building up on a wing’s leading edge.
- Ongoing evaluation of a computer software tool
that helps airlines find better routes to fly around bad weather while
their airplane is already in the sky and on its way. Tests so far
involving American Airlines and the FAA already show promise the tool
can help save money in fuel costs and reduce delays for passengers.
- Flight tests of a flexible trailing-edge wing flap
that bends and twists during takeoffs and landings while maintaining a
seamless interface with the rest of the wing. The tests will help
determine if the idea is a good one for improving aerodynamic efficiency
and reducing noise.
“This only scratches the surface of what we have planned, but it
does represent what the first 'A' in NASA is all about,” Shin said.
“This is our mission. This is what still puts the fire in our bellies
and keeps us motivated as we come to work each day, ready to tackle a
new century of leading-edge research.”
