itka za titulu najbržeg moto-sportiste na
svetu nastavljena je u julu u Budimpešti. Akrobatski
avioni vazduhoplovne Formule 1 dostizali su brzine
i do 370 kilometara na sat dok su leteli slalom iznad
malog, nepuna dva kilometra dugog prostora između
dva mosta na Dunavu. Desetine hiljada gledalaca
okupilo se na centralnim obalama reke, da uživaju u
retkom spektaklu.
Potrebno je mnogo smelosti gradskih vlasti da do-
zvoli održavanje tako brze trke u najužem gradskom
jezgru, čak i kad se letački program odvija iznad reke,
a bezbednost je po najvišim standardima. Mađarska
prestonica je jedino mesto na svetu gde je, za potrebe
trke, bilo dozvoljeno da avioni proleću ispod mosta.
Zapravo je to bila njihova obaveza, jer se na stazu
ulazilo proletanjem ispod Lančanog mosta, jednog od
najpoznatijih turističkih motiva Budimpešte.
Proletanje ispod mosta organizatori su procenili
kao bezbedan manevar jer je je visina od površine
vode do svoda iznosila 12,5 metara. Ipak, za 14 pilota
koji se takmiče u borbi za titulu svetskog šampiona
trka u Budimpešti spada među najteže jer je potrebno
mnogo oštrih promena pravca kretanja i visine na
skučenoj stazi. Njihova tela izložena su snažnim i
mnogobrojnim uticajima različitih sila. Kada avion za
trećinu sekunde napravi obrt oko ose, ili opterećenje
u okretu dostigne 10g, potrebna je velika veština da se
održi prisebnost.
Takmičarski letovi na stazi u Budimpešti trajali su
oko 60 sekundi, sa prolaskom kroz šest kapija. Pobed-
nika odlučuju desetinke sekunde, ponekad svega ne-
koliko stotinki. Na to može da utiče ne samo veština
pilota, već i bolje predviđanje spoljašnje temperature,
brzine vetra i vazdušnog pritiska u trenutku leta. Zato
svi timovi imaju sofisticiranu opremu za predviđanje i
analizu staze i uslova trke.
Sledeća trka održaće se ovog meseca u Askotu, u
Velikoj Britaniji, iznad jednog od najčuvenijih hipodro-
ma na svetu.

The battle for the title of
the fastest motorsport racer in
the world continued in Budapest
in July. The aerobatic aeroplanes
of the aviation Formula 1 reached
speeds up to 370 kilometres per
hour as they flew the small slalom
course covering a length of less
than two kilometres between two
bridges over the Danube. Tens of
thousands of spectators gathered
on the central banks of the river to
enjoy this rare spectacle.
A lot of courage was needed for
the local authorities to permit the
staging of such a fast race in the
very heart of the city centre, even
though the flight path was restrict-
ed to the river area and the highest
safety standards were maintained.
The Hungarian capital is the only
place in the world where, for the
purposes of the race, planes were
permitted to fill under bridges.
Indeed, they were actually obliged
to do so, because the course could
only be accessed by flying under
the Chain Bridge, one of Budapest’s
most popular tourist landmarks.
The organizers estimated that
flying under the bridge was as a
safe manoeuvre, due to the gap of
12.5 metres between the surface
of the water and the height of the
vault. However, for the 14 pilots
competing in the battle to become
world champion, the Budapest race
is among the most difficult, due
to the need to make many sharp
turns and because of the height of
the restricted course. Their bodies
are exposed to strong and numer-
ous influences of different forces.
When the plane makes a revolu-
tion around its axis in just a third
of a second, or the load burden
in turning reaches 10g, great skill
is required in order to maintain
composure.
Competition flights on the
Budapest course lasted about 60
seconds, with pilots required to
traverse six gates. The winner is
determined on the basis of tenths
of a second, sometimes only a few
hundredths. This can be influ-
enced not only by the skills of the
pilots, but also better predicting of
the external air temperature, wind
speed and air pressure at the time
of flight. That’s why all the teams
have sophisticated equipment to
predict and analyse the course and
race conditions.
The next race will be held this
month in Ascot, UK, above one of
the world’s most famous race-
courses.
