Boeing 757, suger in fågel i motorn vid start

Jag vet inte om ni har sett den här videon, jag hade det i alla fall inte. En Boeing 757 suger in en fågel i höger motor i samband med start och drabbas därigenom av motorfel.
Allt fångas på video av en planespotter.

Hej!

Fan va grymt (Eller hur man nu ska uttrycka det).

Fast å andra sidan, har hört (av en flygtekniker) att dom skjuter in frysta kycklingar i motorn med ett "granatkastare" vid testkörningar av motorn.

Och en motor bör ju endast strimla en fågel, och inget mer med det? Eller?

Och stänger han av motorn för att förhindra branden?


ps. diggar pilotens engelska :tupX2

 

På tal om fåglar, jag såg på discovery channels "Myth Busters". Där sköt dom kycklingar i 200knyck mot en skrotad PA-28. Flygfät gick rakt genom rutan.

Har själv fångat en fågel med flygplanstjärten. Vingpennor satt kvar blandat med blod på sidrodret. Vågar knappt tänka på ifall den gått in i rutan.

 

Jaså? Är rutorna på små maskiner såpass klent byggda?

Man har ju kört in i en fågel med bilen ett par gånger, visserligen inte i 200 km/h, men får bara en känsla av att bilrutor är något starkare än flygplansrutor :X

 

Jag kanske minns fel, men den fågeln som gick rakt igenom rutan på Myth Busters var väl djupfryst? Minns att de provade med en tinad fågel, och den gjorde då mindre skada. (Om jag nu inte minns fel, eller om det var ett annat program jag tänkte på.)

 

En fågel kan mycket väl slå sönder motor och annat, och totalhaverier är inte ovanliga bland militära fpl efter en fågelkollision.

En klassisk fågelkoll med Hawk:

Spontant upplever jag att myth busters är lite väl populärvetenskapligt. Det är ett flertal gånger som deras experiment utan tvekan skulle ratas som bevis, så ta inte Myth Busters på för stort allvar. Se det som ett underhållande lekprogram med ett visst mått av verklighetsanknytning.

 

I sammanhaget så är den tunna plexirutan på en PA28 inte mycket att hänga i julgranen, dock så brukar propellern ta en del av fågel på väg mot vindrutan.

 

Jag roade mig i helgen med att försöka mig på en transkript av radiotrafiken från Thomson-incidenten. (Jag har inget bättre för mig efter en löpolycka som har slutat med ett gipsat ben som ska förvaras merparten av tiden i högläge.)
Jag fixar tyvärr inte all radiotrafik, så ni får gärna komplettera/korrigera där så behövs.
De partier jag är säker på att ajg inte har klarat är markerade med [...]. Det är möjligt att jag har uppfattat annat fel också.

En förlängd film, den jag har plockat radiotrafiken från, hittar du här:

Manchester Tower:
Alright.

 

Håller med dig om att programmet inte håller måttet vetenskapligt sett men i detta fallet ser man hur sårbar man är vid en krock med tex. kanadagås eller storleken rovfågel. Tror inte dom fejkat att rutan går sönder för att popularisera programmet
