1954 Taa Promo

[siznaudin]

Good stuff here, and in amongst it there's a brief clip of a Convair 240 rear steps in use, too.

 

That's be the same aircraft I flew in when I was still a freckle faced redhead in short pants.

 

(doesn't bear thinking about...)

I don't seem to be able to get the link to play, Geoff; maybe autoplay is disabled on my computer or something like that. Found this after a search on the tube, I'm hoping it's the same one.

 

Cheers, Willie.

Hi Willie ... yep, that's the one. Can't explain auto-play failure - IT stuff definitely not my strong suit.

 

I'l toss this one in even if it's off-topic: found it on the web a couple of days ago and ... naturally you came to mind!

Thanks, Geoff; things sure have changed since that TAA promo. It's a classic bit of history and nostalgia.

 

Nice photo of the F-4 re-fuelling, and a good shot of the intakes and vents as well. It reminds me of a video clip that surfaced a year ago; I'll post it in the video section for anyone interested.

 

Cheers, Willie.

Here's another interesting one. How different thinks look in hindsight.

On the subject of Convairs, here's a 1965 Convair 600 promo.

 

 

Cheers, Willie.

Good one - and why is it I've only ever associated water-methanol injection with piston engines, excluding (up to now) turbo-props...:confused:

Hmm. The pilots went on strike in 1989 and caused all the trouble hay!

 

How long did it take to make that Ansett add to get scabs to come and work here when the big fight got going.

 

The airlines knew exactly what they were going to do, well before the day the pilots resigned in August 1989.

Good one - and why is it I've only ever associated water-methanol injection with piston engines, excluding (up to now) turbo-props...:confused:

Geoff, as far as I know, water injection died out as a means of thrust augmentation in the seventies, once high by-pass turbofans came on the scene with their ample thust reserves for take-off. It was a good idea at the time though, when they only had turbojets and low BP turbofans.

 

Nomally the water was injected upstream of the compressor, which vaporizes causing temperature to drop, in turn causing density, hence mass to increase, providing the extra thrust due to increased mass flow rate.

 

According to theory, thrust depends on airstream velocity and mass flow rate, which is linked to air density (mass=density x volume). Density increases with pressure and decreases with temperature, so the water injection helped at high altitude airports, and on hot days.

 

Not sure about the methanol mix though,whether it was injected direct into the combustors or not.

 

Here's a rough way to start up on a hot day. It's an An-24 turbo-prop. Fairly sure it's at Chita, just north of the Mongolian border in Eastern Russia.

 

 

Cheers, Willie.

Indeed Sixties,that American pilot says at the beginning he had been with Ansett since early September....a bit over a week since the dispute started,:eek:
