Never sayi dont think about my fellow forumites.......

Heat shimmer and flames.....




Big wheels.....

Don,t ya just love the today,s Cameras and the people behind them

You get about 250 landings on a set of mains, and they don't come cheap.
I've often wondered if it might extend that a lot if you were to spin them up before landing.
A simple wind-driven turbine hub might do.

Funny you should say that ... I've often thought exactly the same thing! Hitting a fairly abrasive surface at 150mph can't be good.

I do remember going on a domestic flight in Poland once - it was a big fixed undercarriage thing - and staring at the wheel outside my window ... it was *totally bald*!!!

The damn busting Lancs had spinning bombs. They just covered the top half of the cylinder with a shroud and the bottom half was exposed to the airflow which lept it spinning giving the bomb much better bounce so to speak.

So they didn't actually spin them up mechanically beforehand? Clever!!

The bomb as delivered was spun by an hydraulic motor - the spin had to be backwards for it to wind its way down the wall.

The very early prototypes yes, later and operational versions, no.
Upkeep's (type 464) that were used during "Operation Chastise" were belt driven from hydraulic motors to give a reverse spin to the device.

Didn't see this one here, that is a nice pic! I bet he pulled a few G's in that maneuver!

It surprises me that he didn't strike the tail on that actually, it's a wicked pitch he's got on it.

Wow
