NASA Connect segment exploring the first flying machines including their design and development. The host demonstrates the flight simulator of the original glider.
And in order to learn how the Wright Brothers refined and improved their flying machines,
00:00:00
we're here at the Wright Experience Laboratory in Virginia.
00:00:07
We're talking with Ken High.
00:00:10
He's the founder of the Wright Experience.
00:00:12
Now, Ken, tell me, how did the Wright Brothers improve upon their flying machine designs?
00:00:14
Well, with each new design and each new flight test, they did small refinements and small
00:00:18
changes to their design.
00:00:24
There may have been many problems at any given stage of the flying machine's development,
00:00:26
but the Wrights only changed one thing at a time.
00:00:31
They were never confused about which change was causing which result.
00:00:34
Ken, that makes sense.
00:00:38
I mean, that way they could select the changes that worked and then continue to refine their
00:00:39
design.
00:00:44
That's right.
00:00:45
And, Jennifer, this is the result of all their hard work.
00:00:46
This is a flying reproduction of the Wright Brothers' 1902 glider.
00:00:48
Ken, this is quite different from their original kite, isn't it?
00:00:52
Not really.
00:00:55
It uses the same principle of wing warping and wing twisting that they used in the original
00:00:56
kite.
00:01:00
But what was so important and so radically different about this glider from their early
00:01:01
designs was that the 1902 glider was the first aircraft ever that solved the problem of controlling
00:01:05
an airplane in all three axes, pitch, roll, and roll.
00:01:12
Okay, Jennifer, this is a control for the elevator, which controls the pitch, which
00:01:17
is the up and down movement of the aircraft.
00:01:22
Control roll, I can shift the hip cradle back and forth.
00:01:25
Watch how the wings twist.
00:01:28
That would change the roll position of the aircraft during flight.
00:01:31
But also wired into the hip cradle is a control for yaw.
00:01:34
Watch how the tail moves at the same time as the wings are warping.
00:01:38
Ken, this is so cool, but can you really fly this?
00:01:41
Absolutely.
00:01:45
We have a 1902 simulator that you can fly.
00:01:46
Come on.
00:01:48
All right.
00:01:49
Jennifer, this is our 1902 glider simulator, and it was developed from the wind tunnel
00:01:50
test that we did on this machine.
00:01:55
Bill Haddon is our expert on this, and he is a good instructor.
00:01:57
He's going to check you out on this and tell you about the machine.
00:02:01
Great.
00:02:04
Nice to meet you, Bill.
00:02:05
Hi, Jennifer.
00:02:06
Tell me about the simulator.
00:02:07
This was based on the wind tunnel numbers generated by taking our full-scale glider
00:02:08
and putting it in the Langley full-scale tunnel in Hampton, Virginia, operated by Old Dominion
00:02:14
University.
00:02:19
And the results of the wind tunnel test were incorporated in a flight simulator by Burrell
00:02:21
Applied Research.
00:02:27
That's their business, making flight simulators.
00:02:28
So when you fly the simulator, you're flying actual wind tunnel data results.
00:02:30
So that's a lot of fun.
00:02:35
Would you like to try it?
00:02:38
I thought you'd never ask.
00:02:39
I'd love to try it.
00:02:40
Okay.
00:02:41
Okay, Jennifer.
00:02:42
On the left, you see your airspeed in knots.
00:02:43
That's 21 knots.
00:02:46
22.
00:02:47
Right there.
00:02:48
Airspeed control is critical.
00:02:50
If you get too slow, it'll stall, and too fast, it can dive into the ground.
00:02:51
It's just elevator control and hip cradle.
00:02:56
When you move the hip cradle, you're warping the wings to control roll, and you're also
00:02:59
getting rudder movement with it.
00:03:04
Well, it took some practice, and it wasn't real comfortable, but I think I got the hip
00:03:06
thing and the elevator thing going.
00:03:09
I was finally able to make a glide that lasted about 63 seconds.
00:03:11
Thank you so much, Bill.
00:03:17
Thank you.
00:03:18
You're welcome.
00:03:19
Well, how was it, Jennifer?
00:03:20
Oh, Ken, it was incredible.
00:03:21
It was incredible.
00:03:22
I'll tell you, it was a little uncomfortable, and it was kind of difficult to maneuver,
00:03:23
but I can really relate to how the Wright brothers must have felt.
00:03:25
They had a lot of stamina in order to be able to do this.
00:03:28
They sure did.
00:03:30
And this 1902 glider, all of their innovations are in this machine, is what they were striving
00:03:31
for.
00:03:36
By 1903, the Wrights were ready to add an engine and propellers.
00:03:37
The Wright brothers' breakthrough in propeller design came when they realized that a propeller
00:03:41
was merely a wing in rotation in a helical pattern, creating lift in the forward direction.
00:03:46
Once they saw the propeller in this way, they were able to use their wind tunnel data about
00:03:53
lift and drag to design an efficient propeller.
00:03:58
Jennifer, we also have a simulator of the 1903 Kitty Hawk flyer.
00:04:02
Would you like to fly this machine?
00:04:07
Of course I would, Ken.
00:04:08
Now, while I take flight on the 1903 flight simulator, why don't you check out how to
00:04:09
build your own flying machine and test its performance?
