Going back a page...
"I pulled the throttles to idle just south of Sicily , but we still overran the refueling tanker awaiting us over Gibraltar."
...is, again, bullshit. 1000 miles to slow down? Is jokes.
Noticeable here that in all the dick-swinging about Lockheeds and Lightnings (but not Lockheed Lightnings), the bullshit there-I-was all comes from the supposed Lockheed pilots. My guess is they are a quiet lot too; I suspect most of this bs on here is fiction from internet pilots.

Somewhere along the line Gibraltar could've got confused with Malta. That'd be more like 60 miles, or about a minute and half at the speed quoted.

Sweet Eurocopter promo video. I enjoyed it anyway.

I think I remember reading that helicopter generally tend to "topped" out at 200mph, the Eurocopter's 250mph doesn't seemed that much of a big deal TBH.

Are you addressing the video or the apparent low increase in top speed by adding the 2 forward facing engines? Yeah, it's no Osprey, but it is still around a 60% increase on the average helicopter top speed.
In other news I have dusted off my old books and I have decided to actually start designing an HPA rather than just talk about it. Going to aim to have got some prelim calculations and thoughts scribbled before an RAES competition in July to meet some more people and see what's going on in the world of HPA at the moment.

^ Really looking forward to you turning up at Norths on that.

Fuck yeah. New Death TT category??

Helicopter airspeeds are limited, mainly, by the velocity of the rotor blades as they travel forward in each rotation. Add that forward velocity to the IAS of the helicopter and it's quite easy for the tips of the blades to go supersonic if you try to go too fast, with the accompanying aerodynamic and blade-falling-to-bits problems that causes. Shaping the tips can help, but basically, it's difficult to make a helicopter go fast.

XH558 just spat out bits of engine on the runway.
Guessing no shows this year! :(

Yeah I saw the Twitter feed. Bad news.

If it can't do shows this year, then it has to be all over for the Vulcan. It exists in a perpetual state of financial crisis, and surely can't survive missing a summer airshow season. Of course if it's just an engine that's gone bang and it can be replaced easily (they do have spares) then it might be ok.

Anyone catch the story of American military planes that were found to contain Chinese unofficial parts? If true, that's a real cause for concern.

bet they saved a fair bit of cash though

True, but I think there would be a quantifiable difference between industrial grade and aerospace grade engineering.

Why the bumpage? Is there something you would like to add?
-
• #796
Not really. It's just my favorite thread and after 3 days of nothing i had a worrying notion that perhaps it was now "uncool".

Something cycling related, Lord Sugar took Cav up in his Cirrus today.

Here, this will make you feel better. A lockheed A-12 (smaller, faster, higher than the SR-71) with a space shuttle in the background.

Lovely. Thank you.
Conventional movie cameras have a shutter speed which is roughly half their frame rate, so typically about 1/48th of a second. They capture a significant amount of motion blur and wouldn't be able to freeze a fast-moving subject against the background.
