Corsair locking pin (looking for photos or diagram)

[Julie]

Hello,
Could somebody on WIX please provide me with information on a Corsair's locking pin. I'm hoping to see images or detailed diagrams. I've seen an exploded illustration of a Corsair's wing, but it doesn't detail a locking pin. I also went on Google images and looked at photos of a Corsair's wing, but again, I'm not sure what's a "locking pin."

The reason is that we are going through some family scrapbooks and there are a couple references to a Corsair's locking pin, but I don't understand what they are talking about.

Thanks in advance. Julie

Hey Julie, the arrow in the photo below points to the wing fold locking pin. There's a similar bit of bracketry on the folded portion of the wing. When the wing folds down, that one little pin locks both sections of wing together so the outer wing doesn't fold in flight.







Here's another good one I found. You can see the silver actuator very well, contrasted against the green.

Thank you, that helps out a lot. The pictures were very helpful. As a side note, it looks like the pin is engaged in the top photo, but not engaged in the bottom photo.

Thanks again.

Julie,
To elaborate a bit more on how the locking pin system works-
With the wings folded up the pilot would move a handle in the cockpit to start the wings to move to the down position.
On the R/H side of the photo is a silver button. This is a sequence valve.
As hydraulic pressure, and then gravity, moves the wing down, it will press on that button of the sequence valve when fully lowered. Then a path is opened for hydraulic pressure to flow to the downlock pin. It will extend as shown in the above photos.
The extension of this pin also pushes on a device that moves a small flap on the top of the wing. This flap covers an area on the top skin and is a mechanical indicator to the pilot that the wing is locked by the locking pin.
The pilot moves the wing fold selector handle to lock and locks the hyd fluid pressure in the downlock pins to hold them in place.
Also another handle is moved that locks the downlock pin mechanically as well.
Hope all of WIX info answers your questions.
