aerodynamics for me were always so tough to understand everyone adjacent
Schappert here of m0 a.com and we are so proud of the hard work the team has put
into making our new private pilot online ground school and I want to continue to
share some of those great new videos with you all including some our new
animations new experiments we're doing here in the studio as well to help you
better understand our online ground school members better understand why an
aircraft stalls aerodynamically Bernoulli's principle
all these factors that go into why in airplane flies and its basic
aerodynamics now if you love this video you're gonna love all the videos inside
the online ground school private instrument commercial I encourage you I
want you to take a two week free trial no strings attached of our online ground
school any course you choose two weeks no strings attached there is a link in
the video description so you can take action on that free trial and start your
two weeks you can hop on some of the Monday night webinars and everything
else I'll stop talking though let's go ahead and let's cut to the actual ground
school clip everyone Jason and back with you talking now about the aerodynamics
of maneuvering flight and what the phrase I want to understand here is
Bernoulli's principle we're gonna understand that at the private pilot
level you need to understand this phrase because it's going to be on your check
ride it's going to be on your knowledge test basically Bernoulli's principle
states as air flows over the wing it speeds up and creates a low-pressure
spot over the wing because the convex shape of the wing which is known as
camber when the airplane is flying air strikes the front of the wing known as
the leading edge then flows over the cambered wing created an area of low
pressure which generates lift meanwhile air flowing under the wing pushes the
wing up the air flowing over the wing has to travel faster to meet the air
flowing under the because of the camber the idea we must
understand is that as the air speeds up the pressure is lowered the air goes
faster over the top of the wing because it has to go further and thus it creates
lift which sucks the airplane upward I can demonstrate Bernoulli's principle by
blowing with this fan between these two balloons now these two balloons are
hanging from strings and think of them as representative of our airplane wings
since they have a curved surface now our first thought would be this fan is going
to blow these two balloons apart but the low-pressure created over the side of
the balloon the wind is literally drawing them together just like the wing
of our airplane is pulled by low pressure just like we're sucked up into
the air when we fly these balloons are being drawn towards each other by the
low pressure created as the air flows over their curved or cambered surfaces
now Bernoulli's principle also states that as we decrease the opening that air
or liquid passes through the air or liquid speeds up which also causes a
decrease in pressure that narrowing of the opening is called a venturi if
you've used a garden hose before and kink that hose you've heard that water
actually speed up in that kink all you essentially did is create a
venturi now let's take a step back and look at our airplane again looking at
the actual wing to take note of the camber we take that wing let's slice it
in half we can now see the venturi which combined with the camber causes the air
over the top of the wing to move faster than the air flowing under the wing
which gives us lift now Bernoulli's principle is going to become important
again especially that idea of a venturi because when it comes to our systems
lesson there's actually a venturi inside what's called the throat of our
carburetor we're gonna learn more about that in some upcoming systems lessons
down the road I wrote the Private Pilot blueprint with
the intention of if I could do my flight training over what I wish someone would
have told me I want that book to be yours for free all I ask is that you pay
