P-51C Mustang Video

I have a video of a P-51C that I hope the members will enjoy. The airplane that is the subject is very nicely restored.

One thing I found odd ... the wheel doors.

Before start-up the doors were open. Then at engine start they close. But after take off they have to open yet again to let the wheels go up. After that they close and remain closed for the rest of the flight. Then before landing they open again to let the geat down but close yet again. But we saw that the doors were open before starting the engine. But maybe that was for a maintenance check.

So quite surprised about this as I would have expected the doors to stay open as long as the gear is down. And I wonder if it similar for other WW2 aircraft?

After engine start, as hydraulics pressurize, inner gear doors close. Normal gear retraction cycles inner doors open, gear retract, and inner doors follow again. On shutdown, as pressure bleeds, the doors sag and open.

twoeagles is correct, the inner doors sag when the engine is off due to loss of hydraulic pressure. Same thing happens on most big aircraft (747, C-17, ect). Look at them after engine shut down, and you will see the elevators and ailerons drooping, just because of no hydraulic pressure. But once it is on, they will spring into the nutureal position, just like the gear doors on the P-51 closing after engine start.

I posted my thread twice. Would you be so kind as to remove the most recent one.

I will put these in the correct place from now on.

Thank you

Very nice video. Have seen this craft in my area last year. Thank you for sharing Captlou.

Thanks to all. I see that no one has got onto the signal the ground crewman gave to the pilot about the doors.
