A320 Nose Landing Gear Design
Hi
Why is the Nose landing gear of the A320 series designed to be more than 90 degrees to the body when extended?

Good Question Needa,
I did the A320 Family mechanical aircraft type course back in 2010. I have just had a bit of a read up in my A320 type course study manuals & it may be due to below reason.
This is word for word from my A320 type course study manual under Nose Landing Gear.
Sliding Tube: The sliding tube includes the wheel axle. It is inclined 9 degrees forward; this design allows the wheels to return freely to the centred position. The two system proximity detectors provide signals for both gear extended and wheels centred positions. The towing lug is designed to shear if the towing load is more than the limit.
In simple terms this means that when the NLG is in down & locked position it would be 81 degrees & that the NLG inclined 9 degrees forward allows the NLG wheels to return freely to the centred position under nose steering conditions.
Hope this helps.

I was under the impression that having a positive angle relative to the direction of travel would mean that if the gear did take a heavy de-rotation the gear itself would be less likely to collapse backwards and end up having the aircraft land on its nose.
