NASA Sci Files segment describing how airplane designer Burt Rutan takes projects from conception to reality, and the features that are the keys to flight.
Hello Mr. Rutan, you've had a lot of experience designing planes.
00:00:00
Could you please show us one of your unique designs?
00:00:09
Oh sure, I love to talk about airplanes.
00:00:11
I've designed some 28 different manned airplanes and also some unmanned airplanes.
00:00:14
One of my favorites is the Boomerang that I'm sitting in.
00:00:21
It is a very safe, long range, light twin airplane and it's the airplane that I fly
00:00:24
nowadays.
00:00:30
Behind me is the Proteus, a high altitude airplane that's used for special missions.
00:00:32
Probably my most famous airplane though is the Voyager.
00:00:39
The Voyager, about 16 years ago, took off at one airport and flew completely around
00:00:43
the world, taking some nine days, and landed at the same airport without refueling.
00:00:49
And that set a milestone in aviation.
00:00:56
Do you have to use your imagination to design these planes?
00:00:58
Oh yes, imagination is extremely important because with an airplane you can look at birds,
00:01:02
you can look at other airplanes, but if you're going to do anything truly new, you have to
00:01:11
create, you have to innovate, and you have to imagine.
00:01:16
Here we are in the office, and this is where airplanes are designed.
00:01:20
It starts with a sketch, and a sketch comes from the mind, it comes from, really from
00:01:25
your imagination.
00:01:31
You imagine what might fly well, and you think about it real hard, and you take a pencil
00:01:33
to a piece of paper, and you put on a piece of paper the creative thoughts that are in
00:01:41
your mind, and that's what imagination is really all about.
00:01:48
Can you show us the Proteus?
00:01:52
Okay, this is Proteus, pretty big airplane.
00:01:54
It's designed to do some very interesting things.
00:01:59
It can fly very high, it can fly more than 10 miles high, so it's up above where the
00:02:02
airliners fly, and it can stay up there a long time, and that's very useful for doing
00:02:08
things like studying the atmosphere, or relaying internet data, that sort of thing.
00:02:14
So let's take a look at it.
00:02:21
Even though this is a very big airplane, with a wingspan of about 90 feet, it's actually
00:02:23
quite light.
00:02:28
It only weighs as much as two cars, but if you fill it up with fuel, it weighs as much
00:02:30
as four cars.
00:02:35
The wings are very long and slender, very smooth, and that's necessary so the airplane
00:02:37
can fly a long time.
00:02:43
The wings are filled with fuel, and the fuel drains down and is pumped up to jet engines,
00:02:46
and jet engines is what makes the thrust that makes the airplane climb, makes it fly, makes
00:02:55
it stay up there.
00:03:01
And thrust is a very, very important thing for airplanes, and thrust will help you win
00:03:03
this contest.
