Danny Fenton Posted June 5, 2014 Share Posted June 5, 2014 I dont know whether its an age thing, having been around aviation all my life, but it still amazes me that the air can support an aircraft of any mass. I understand the science, but it still never fails to amaze me...... Ooo and watch out for the Dreamliner, at 1:35 look at the wing flex...... scary....

Martyn K Posted June 5, 2014 Share Posted June 5, 2014 Hi Danny What I think was more scary was the fin and tailplane fluttering on the Antonov as it was running up the engines at the end of the runway. I didn't expect that. There must have been several feet of movement at the tip of the fin. Regarding flexi wings, when I worked at Heathrow, we always said that there was two schools of aircraft design strategy. The British aircraft at the time, (BAC1-11, Trident etc) always had a very rigid structure with very little movement of the wings in flight, there was very little flex, while the American aircraft always seem to have very flexible structures. You could see (as you could on the Dreamliner), several feet of dihedral appear (on Boeings, Lockheeds and McDs) as the aircraft accelerated to take off velocity. I was always intrigued how they could allow a wing to be so flexible in bending yet maintain adequate torsional rigidity, which clearly they did.

Danny Fenton Posted June 5, 2014 Author Share Posted June 5, 2014 Strewth Andy, that must take some "chucking" of a hill, I presume its a sloper? Hi Martyn, Yep I noticed that, the engines were run up to what looked like full power and held on the brakes for quite some time too, which surprised me. I guess they really didn't want an engine failure at takeoff. I guess they have done their sums with regards the flexing the Airbus flex a fair bit too.

Bill_B Posted June 5, 2014 Share Posted June 5, 2014 Notice how the Emirates A380 fin towers well above the Antonov's fins, but back in it's day the An was a truly impressive machine. As a comparison, the six An engines produce just over 300,000lbs of thrust, where as the four engines of the Emirates A380 produce roughly 320,000lbs of thrust.

Andy Meade Posted June 5, 2014 Share Posted June 5, 2014 Danny - yup that's Mr Cocker's PSS Antonov. It held the world record for a long time for being the largest RC aircraft! Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted June 5, 2014 Share Posted June 5, 2014 Would love to see a video of it being hand launched Andy John Quote Link to comment Share on other sites More sharing options...

Danny Fenton Posted June 5, 2014 Author Share Posted June 5, 2014 Thanks guys, and you have managed to turn the thread round from full scale aviation to end up with scale RC modelling Impressive indeed! Quote Link to comment Share on other sites More sharing options...

Erfolg Posted June 5, 2014 Share Posted June 5, 2014 The full size Antonov, flew over our field during the last year, possibly 6 months back, apparently having departed Ringway. The A380 (Emirates) flies over the field on a regular basis, at about 14:30. Perhaps not as impressive, as I suspect it is always a good bit higher than the Antonov was. Both impressive though, even from the ground. I do not think either has impressed (that should be annoyed) with noise, both being quiet. I have noticed very recently that a ATP flying over (not seen one for a bit) was noisier than most of the pure Turbo/Fan Jets that fly over on a regular basis.

john stones 1 - Moderator Posted June 5, 2014 Share Posted June 5, 2014 We see it at Doncaster (Finningley) every time you see it, you think "nah that can't be right" Back on track now Danny P.S. great shots Phil thanks Quote Link to comment Share on other sites More sharing options...
