your probably wondering why more knowledge streamers
well or find out how the road and in that time
brother ben charlie
sierra dot is this is the saudis hostesses
what are the best ways for scientists to study here from around object is it a
wind tunnel
a wind tunnel as an enclosed spaces with airflow over an object to be carefully
controlled instead
therefore types of wind tunnels subsonic
trend sonic
supersonic
and hypersonic
investor langley research center has all of these types of tunnel is one of the
most extensive winslow facilities
each type of wind tunnels uses the object to the different ones
these wind speeds are based on the speed of sound which is about one thousand two
hundred and thirty five kilometers per hour
depending on altitude air temperature
in warmer air sound travels in the faster
so the speed of sound is how fast sound waves travel through the air
palestinian appeal
and i saw a lightning bolt one point six planters away
five seconds from the time i saw the flash
to hear the phone
offenders traveling at the speed of sound
that wind tunnels measure airflow for help that figures moving using the same
scale used for the speed of sound
subsonic wind tunnel so used to study their floor of politics as sort of
speaks out
like ours commercial jets
trend sonic wind tunnels are used to state air traffic and fly around the
speech that supersonic it hypersonic tunnels are used to study might be on
the speed of sound
in fact hypersonic lentils can study flight office seven times the speed of
sound
but how do you need me as a nasa get a plane to that fascinating closed area
the object of testing stays still any care moves instead
we use wind tunnels too
provide information on the air dynamics of directly various types of vehicles
weekend do that at safeway very controlled conditions in the wind tunnel
we don't have to build a full size airplane and risk the pilot's life we
always test new configurations and went all first
make sure they're safe
understand their characteristics and then we move on to build sewer
two different types of wind tunnels are used to test different x_-wing has on
aircraft flying through the air
for example
the nasa langley
fourteen by twenty two points subsonic tunnel
is used to test certain object the trouble unless the market one or less
than the speed of sound
the fourteen but we believe the designed that most of the performance of aircraft
goes because it's important to fair prince's during that period very
important do you think the picked up in flames
we consider decaf and made the most important part of our white
that you don't think optimistically
diversified doesn't mean
than the other hand off upping with uh... aircraft
we best structures
you know one clue rounded
anywhere from large buildings do
radar structures
elizabeth youthful thickness on the
and we said we just got into as being motor sports such as this horrors
in in the race
in office parachutes
has built a wheelchair in nineteen seventy nine
did nasa national trends on a personal uses nitrogen gas to study the flow over
with the sections and other moms
because this winter most trained signing
it's used to test objects but amid the flights visa around model
just as sound moves faster and warmer air warmer temperatures in the wind
tunnel make impressed
the langley eight foot high temperature tunnel as a hypersonic
uses superheated gas to simulate speeds up to mark seven
that seven times the speed of sound
messy but as a wind tunnel that's built just the study help airflow takes care
of crap that are spinning out of control
well have exploded everywhere
logo
you know globally the wind tunnels at nasa langley research center or hoping
to make air travel even safer
and a lot faster
and you won't believe some of the other things that are tested in nasa went on
cars in boats and even the material for olympic swimsuits
leavitt the nasa to find a way to best aerodynamics without even stepping
outside
okay
hopeful
