hi I'm Vince whitfill with a NASA
scientific and technical information
program today we're at NASA Langley
Research Center where some of NASA's
best are working to advance and develop
new technologies to improve our everyday
lives and even benefit all of
humankind's did you know NASA has been
contributing to the advancement of the
aviation industry for decades some of
these environments include damage
tolerant fan casings glass cockpits
icing detection and even grood runways
which have improved aircraft tire
friction performance in wet conditions
by as much as 300 percent a green
related technology that was developed
and tested here at NASA Langley is Apple
Trudy's rod stitched efficient unitized
structure or Perseus the stitches in
Perseus structures are used to join
lightweight composite material layers
together to help in the development of
lighter damaged tolerant aircraft
traditionally aircraft components are
held together using rivets and bolts
this requires that holes be drilled into
components which increases the
likelihood that cracks can develop and
pose other safety concerns over time
Perseus would allow aircraft to be
constructed without these fasteners
which would assist in a lighter and
stronger final product this reduced
weight structure could help allow jet
engines to burn less fuel therefore
making it safer and greener to fly for
more detailed information about NASA's
Perseus composite design you can find
the conference paper titled development
of the Perseus multi Bey pressure box
for a hybrid wing body vehicle on the
nasa technical report server or mtrs the
NT RS is one of the world's largest
repositories of aerospace STI and
features records dating from the NACA
era to today's cutting edge research
that's all for today thanks for watching
and we'll see you next time
you
