ABOUT THE SPEAKER
Markus Fischer - Designer
Markus Fischer led the team at Festo that developed the first ultralight artificial bird capable of flying like a real bird.

Why you should listen

One of the oldest dreams of mankind is to fly like a bird. Many, from Leonardo da Vinci to contemporary research teams, tried to crack the "code" for the flight of birds, unsuccessfully. Until in 2011 the engineers of the Bionic Learning Network established by Festo, a German technology company, developed a flight model of an artificial bird that's capable of taking off and rising in the air by means of its flapping wings alone. It's called SmartBird. Markus Fischer is Festo's head of corporate design, where he's responsible for a wide array of initiatives. He established the Bionic Learning Network in 2006.

SmartBird is inspired by the herring gull. The wings not only beat up and down but twist like those of a real bird -- and seeing it fly leaves no doubt: it's a perfect technical imitation of the natural model, just bigger. (Even birds think so.) Its wingspan is almost two meters, while its carbon-fiber structure weighs only 450 grams.

Fischer says: "We learned from the birds how to move the wings, but also the need to be very energy efficient."

It is a dream of mankind
0
0
3000
Është ëndërr e njeriut
00:18
to fly like a bird.
1
3000
2000
të fluturoj si një zog i vërtet.
00:20
Birds are very agile.
2
5000
2000
Zogjët janë shumë të shkathët.
00:22
They fly, not with rotating components,
3
7000
3000
Ata fluturojnë, jo me kompontentë rrotullues,
00:25
so they fly only by flapping their wings.
4
10000
3000
pra ata fluturojnë vetem duke i lëvizur krahet e tyre.
00:28
So we looked at the birds,
5
13000
3000
Pra ne i shiquam zogjët,
00:31
and we tried to make a model
6
16000
3000
dhe provuam ta bejmë një model
00:34
that is powerful, ultralight,
7
19000
3000
i cili është i fuqishem, shumë i lehët,
00:37
and it must have excellent aerodynamic qualities
8
22000
4000
dhe duhet të ketë kualitete të shkelyqera të ajrodinamikes
00:41
that would fly by its own
9
26000
2000
i cili do të fluturonte nga vetvetja e tij
00:43
and only by flapping its wings.
10
28000
3000
dhe vetem duke i lëvizur krahet e tijë.
00:46
So what would be better [than] to use
11
31000
3000
Pra qfar do të ishte më e mirë [sesa] ta përdorim
00:49
the Herring Gull, in its freedom,
12
34000
2000
Herring Gull, në lirin e tijë,
00:51
circling and swooping over the sea,
13
36000
2000
duke u rrotulluar mbi detin,
00:53
and [to] use this as a role model?
14
38000
3000
dhe [ta] ta përdorim si model?
00:56
So we bring a team together.
15
41000
2000
Pra bashkuam një ekipë
00:58
There are generalists and also specialists
16
43000
3000
Ka të përgjitheshem dhe gjithashtu specialistë
01:01
in the field of aerodynamics
17
46000
3000
në fushen e ajrodinamikës
01:04
in the field of building gliders.
18
49000
2000
në fushen e ndërtimit të ajroplanve.
01:06
And the task was to build
19
51000
2000
dhe detyra ishte të ndërtojmë
01:08
an ultralight indoor-flying model
20
53000
3000
një model fluturues ultra i hollë
01:11
that is able to fly over your heads.
21
56000
3000
i cili është në gjendje të fluturoj në duart tuaja.
01:14
So be careful later on.
22
59000
3000
Pra beni kujdes më von.
01:19
And this was one issue:
23
64000
2000
Dhe kjo ishte një qështje:
01:21
to build it that lightweight
24
66000
2000
për ta ndërtuar atë peshë të lehet
01:23
that no one would be hurt
25
68000
2000
nga e cila askush nuk do lendohej
01:25
if it fell down.
26
70000
3000
po të biente poshtë.
01:28
So why do we do all this?
27
73000
2000
Pra përse e bejmë të gjithë këtë?
01:30
We are a company in the field of automation,
28
75000
3000
Ne jemi një kompani në fushen e autolëvizjes,
01:33
and we'd like to do very lightweight structures
29
78000
3000
dhe ne dëshirojmë të krijojmë struktura shumë të lehta
01:36
because that's energy efficient,
30
81000
2000
spese kjo është energjia eficiente,
01:38
and we'd like to learn more about
31
83000
3000
dhe ne dëshirojmë të mësojmë më shumë rreth
01:41
pneumatics and air flow phenomena.
32
86000
3000
pneumatikes dhe fenomenit të lëvizjes së ajërit.
01:44
So I now would like you
33
89000
3000
Pra tani dëshiroj që ju të
01:47
to [put] your seat belts on
34
92000
2000
vendosni rripin e sigurisë
01:49
and put your hats [on].
35
94000
2000
dhe kapelat tuaja.
01:51
So maybe we'll try it once --
36
96000
3000
Pra ndoshta do të provoj vetem një herë të fluturoj
01:54
to fly a SmartBird.
37
99000
2000
si një zog i menqur.
01:56
Thank you.
38
101000
2000
Faliminderit.
01:58
(Applause)
39
103000
6000
(Duartrokitje)
02:14
(Applause)
40
119000
17000
(Duartrokitje)
02:52
(Applause)
41
157000
15000
(Duartrokitje)
03:07
So we can now
42
172000
2000
Pra ne mund të fluturojmë tani
03:09
look at the SmartBird.
43
174000
3000
shiqoni zogun e menqur.
03:12
So here is one without a skin.
44
177000
3000
Pra këtu është një pa lëkur.
03:15
We have a wingspan of about two meters.
45
180000
3000
Ne kemi një krah rreth dy metras
03:18
The length is one meter and six,
46
183000
3000
Gjërsia është një meter e gjashtë,
03:21
and the weight,
47
186000
2000
dhe pesha,
03:23
it is only 450 grams.
48
188000
3000
është vetem 450 gram.
03:26
And it is all out of carbon fiber.
49
191000
3000
Dhe e gjitha është me fibra karboni.
03:29
In the middle we have a motor,
50
194000
2000
Ne mes kemi një motorrë,
03:31
and we also have a gear in it,
51
196000
4000
dhe gjithashtu ne kemi një ndërrues shpejtësie në të,
03:35
and we use the gear
52
200000
2000
dhe ne e përdorim ndërruesin
03:37
to transfer the circulation of the motor.
53
202000
3000
për të transferuar rrethrrotullimet e motorrit.
03:40
So within the motor, we have three Hall sensors,
54
205000
3000
Pra brenda motorit, ne kemi tri salla senzorësh,
03:43
so we know exactly where
55
208000
3000
dhe ne e dim saktësisht se ku
03:46
the wing is.
56
211000
3000
është krahu.
03:49
And if we now beat up and down ...
57
214000
3000
Dhe nese tani ne rrëzohemi posht dhe lartë..
03:56
we have the possibility
58
221000
2000
ne kemi mundësin
03:58
to fly like a bird.
59
223000
2000
të flutrojmë sikurse një zogë.
04:00
So if you go down, you have the large area of propulsion,
60
225000
3000
Pra nëse shkon posht, kemi zonen e madh të propulsionit,
04:03
and if you go up,
61
228000
3000
dhe nese shkoni lartë,
04:06
the wings are not that large,
62
231000
4000
krahet nuk janë aqë të mëdha,
04:10
and it is easier to get up.
63
235000
3000
dhe është lehet të ngritesh lartë.
04:14
So, the next thing we did,
64
239000
3000
Pra gjëja tjetër që ne bem,
04:17
or the challenges we did,
65
242000
2000
apo sfida që bëm,
04:19
was to coordinate this movement.
66
244000
3000
ishte për të kordinuar këto lëvizje.
04:22
We have to turn it, go up and go down.
67
247000
3000
Ne duhet ta ndezim, shkojmë lartë dhe poshtë.
04:25
We have a split wing.
68
250000
2000
Ne duhet ti ndrrojmë krahet.
04:27
With a split wing
69
252000
2000
Me ndrrimin e krahve
04:29
we get the lift at the upper wing,
70
254000
3000
ne marrim një ngritje të krahut të lartë,
04:32
and we get the propulsion at the lower wing.
71
257000
3000
dhe marrim propolisin tek krahet e poshtem.
04:35
Also, we see
72
260000
2000
Gjithashtu, ne shofim
04:37
how we measure the aerodynamic efficiency.
73
262000
3000
sesi e masim eficientin e ajrodinamikës.
04:40
We had knowledge about
74
265000
2000
Ne kemi njohuri rreth
04:42
the electromechanical efficiency
75
267000
2000
elektromekanikës eficiente
04:44
and then we can calculate
76
269000
2000
dhe pastaj ne mund të kalkulojmë
04:46
the aerodynamic efficiency.
77
271000
2000
eficientin e ajrodinamikës.
04:48
So therefore,
78
273000
2000
Pra kështu,
04:50
it rises up from passive torsion to active torsion,
79
275000
3000
rritet nga përdredhja pasive në atë aktive,
04:53
from 30 percent
80
278000
2000
nga 30 përqind
04:55
up to 80 percent.
81
280000
2000
deri në 80 përqind lart.
04:57
Next thing we have to do,
82
282000
2000
Gjëja tjetër që ne duhet ta bejmë,
04:59
we have to control and regulate
83
284000
2000
ne duhet ta kontrollojmë dhe rregullojm
05:01
the whole structure.
84
286000
2000
komplet strukturen.
05:03
Only if you control and regulate it,
85
288000
3000
Vetem nëse e kontrollon dhe e rregullon atë,
05:06
you will get that aerodynamic efficiency.
86
291000
3000
ju do të përfitoni eficientin e ajrodinamikës.
05:09
So the overall consumption of energy
87
294000
3000
Pra konsumi i përgjithëshem i energjisë
05:12
is about 25 watts at takeoff
88
297000
3000
është rreth 25 vat
05:15
and 16 to 18 watts in flight.
89
300000
3000
dhe 16 deri 18 vat në fluturimit.
05:18
Thank you.
90
303000
2000
Faliminderit.
05:20
(Applause)
91
305000
6000
(Duartrokitje)
05:26
Bruno Giussani: Markus, I think that we should fly it once more.
92
311000
3000
Bruno Giussani: Markus, mendoj se duhet të fluturojmë edhe një herë.
05:29
Markus Fischer: Yeah, sure.
93
314000
2000
Markus Fischer; Po sigurisht.
05:31
(Laughter)
94
316000
2000
