VC10 Swept Wing Growth Poster
Guys,
I have been trying to explain swept wing growth to a child of the magenta line and recall that there used to be a very good flight safety poster back in the day which showed the problem using a VC10. Would any of you descent chaps have a copy of the image by chance please?
Thank you
MM

Some info here: https://www.skybrary.aero/index.php/...earance_Hazard
Any incident involving it here: https://www.skybrary.aero/index.php/..._City_UK,_2016
Although the references are to the AAIB report, it was in fact almost a copy and paste of the report I wrote for our internal investigation. Watching the CCTV of the event gave as strong an illustration possible of what wing growth looks like in practice!

I have the same edition of HtBJs!! Thank you for the Skybrary links, I have used them but I just seem to remember that that RAF flight Safety poster explaining it with the VC10 was the best picture I have seen.

Ah! RAFEng posted whilst I was typing. I remember a XV Squadron Buccaneer managed to break its Speedbrake on a HAS whilst turning with wings folded. Beware of swept tail growth?

When turning with nose wheel steering, no differential brakes or thrust -
The tightest radius of turn occurs for points abeam the main gear.
Points ahead of the main gear have a larger radius of turn but pull away from objects to the outside as soon as the turn starts. With a swept forward wing you would have the opposite issue. You would need to account for obstructions INSIDE the turn before turning.
Points behind the main gear also have a larger radius of turn but initially move torards the outside as the turn starts. Some busses have a large rear overhang behind the axle and suffer the same effect.
To visualise the effects consider the limiting case with the nose steering wheels at 90 degrees to the direction of travel and with some magic propulsion system that didn't care about that - A tug for example. The size of the effect varies continuously between the two extremes, zero degrees and 90 degrees. In this case the aircraft pivots about the point between the two main landing gears.
Demonstrate it with a vehicle without wings. Much simpler to visualise and the effect is identical.
As ever it been YouTubed already.

Not VC10s, but Victors - memories of peering out of my little window when taxying at unfamiliar airfields and advising the captain "clear starboard" with my fingers crossed, hoping that we really were

The nosewheel track is also a subject which I have had to train too many times and that diagram is useful
