Avro Vulcan Howl - XH558

Описание: The last time we ever saw an Avro Vulcan in Scotland was the Scottish International Airshow in 2015 when she returned to her base from Perstwick Airport with gear down due to an issue with the gear.

The takeoff here has the famous howl

The howl is unique to the 200 series airframes. It is caused by approximately 100 kilos of air per second being sucked through a square hole which then changes into a smaller oval hole and then a slightly smaller round hole (small is relative here.) Try blowing over the neck of a glass bottle and you’ll get a similar effect (though not as spectacular). 558 starts to howl at about 87% throttle and the howl continues until about 95%. To get the full effect you need to be stood forward of the intakes, about 4 to 5,000 foot down the runway is a good place at an air show where she is taking off. Of course I would say the absolute best place to get the full effect is underneath the jet during an engine run!

The last airworthy Vulcan (XH558) was restored to flying condition by the Vulcan to the Sky Trust. The first post-restoration flight, which lasted 34 minutes, took place on 18 October 2007. After performing displays every season from 2008 until 2015 inclusive, XH558 last flew on 28 October 2015. This was due to the withdrawal of support from the "technical authorities" without whom the aircraft is prohibited from flying, under Civil Aviation Authority (CAA) regulations. The aircraft structure and systems are 10% beyond the flying hours of any other Vulcan, meaning identifying signs of fatigue and stress failure were becoming more difficult
