Discovery Wings's propellers

Andy, when Melv engages the gear that operates his arse, float the tape my way and I’ll do the usual to it.

Robbo
that was the plan I was already formulating.
Good weekend??
Andy

I have it on tape somwhere but I just can’t be ar5ed to go look for it!
Melv

Hiscock
go and shift your idle tart’s a*se and look for it. I need to borrow it.

When you’ve found it PM me.

I’m pretty sure that was from ‘The World About Us’ series. Shown on a Sunday evening on BBC2.
If anyone has a copy of this in any format please speak up now.
It was a great program.
Cheers

[QUOTE=stewart1a] going back through time? [/QUOTE]Most amusing.

The point is, regardless of whether a blade rotates clockwise of anti-clockwise, they must always lead with the leading edge (the thicker edge) of the aerofoil of each blade. Theirs don’t always.

Maybe they are connected to British engines?

So which way does a British engine turn? 🙂 Hint: Review both Rolls Royce Merlin and Griffon before answering. 🙂

font overload

I think our warm beer is affecting you. Let’s just hope you haven’t got Centaurus-suitable blades on your corncob!

strobe effect

Interesting point, but, unfortunately, not relevant 🙁 . These propellers are like logos; they have no aeroplane attached, rotating very slowly against a computerised background. But I know what you mean. I disagree on the bit about kids not putting their hands in fans though. 😮

just havnt researched their subjects adequately

My thoughts exactly. Pity.

Janie, How do you know which way the aeroplane was flying silly?

You’ve got a good solid point there, Melvin. Now, do you want me to bite the bait and go for your throat!! :dev2: :diablo: :dev2:

maybe it’s her eyesight

That’s a topic for the General Discussion after a few bevies – not here!

If Janie needs a font like that, maybe it’s her eyesight and not the TV!!!!

I havent seen the program specifically but I suspect the image you describe is due to the strobe effect, the original film of the aircraft is framing (flashing “still” images) at a different frequency to the television image, and the difference is causing the motion to appear backwards. PAL TV in Europe/Australia is framing or flashing “still” images at 50 times a second.

The same situation often occurs with films with “1930’s” or sports cars with spoked wheels, the speed of rotation of the wheel or propellor itself may also figure into the strobe effect and the rotation suddenly appears to reverse with and increase or decrease in engine speed.

For those interested in scientific experiment, putting a revolving fan in front of a TV screen, or waving your hand behind a fan and viewing from the front can create a similar effect, waving your hand “in” the fan is not recommended for the kids (viewing this forum) to try at home, as it might create a somewhat different effect!

Actually, the props, both single and contra rotating…all start off slowly and then spin up to speed. You know it going backwards cos on the contra rotating prop and some of the singles, the de-ice / leading edge protective strip is going backwards. Probably find the jet engine they show spooling up is in reverse as well !!!!

Bl**dy shame really cos it spoils the adverts that show forthcoming aviation programs and if they cant get the advert lead-in right, makes you wonder about the actuall program.

The old Horizon doc about the Confeds

Janie, How do you know which way the aeroplane was flying silly? It could have been flying backwards . . .

besides, they need to add in some variety somehow to take your mind off the slightly repetitive nature of the programming. (“John Nicol Flies . . .” – Err, does he? he is a navigator . . .)

At least they know roughly what a propellor is. Part of my RAeS talk included the bit about one of the BBC programmes on Farnborough in the late 80s or early 90s having a whole segment about in-seat video screens!

Stuff I’d like to see put on Discovery wings:

Mitchells do fly in IMC
The making of Memphis Belle
The BBC programmes from 1984 about the WW1 aviator Chabot
The old Horizon doc about the Confeds

But at least they don’t repeat “The Airshow”

or maybe the people who do the adverts for discovery wings just havnt researched their subjects adequately?

Wow, font overload…

What was the question??? My mind is spinning!!!

Maybe they are connected to british engines?
