Re Scott's post of 12/21/04 I was fascinated to see
a figure of 25lb given as a test parmeter to determine the effectiveness of the
gas spring used for emergency extension of the nose gear.
I presume that this is a calculated figure using
the lengths of the mving parts of the mechanism related to the 100lb gas
spring. Could Scott tell us where this figure came from and whp originally
devised it. I hafd been fussing over the item on the annual which calls
for a test to verify the gas spring and had not as yet come up with an in situ
test. takung the gas spring off to test it is a pain.
Incidentally I have had the pressure on both sides
syndrome. So far only when I have had the plane on jacks. Eventually
it bleeds off. All pressures are to specification.
The other thing that has happened to me is that the
RH inner gear door is slow to close and the propwash appears to be bending the
actuating cylinder rod end and also twisting the hinge and causing it to crack
at the after end. It works fine in the barn!! I cannot find a reason
for it other than the pressure does not peak and shut off until the door is
closed. I have HP and LP pressure gauges. Right now I fly with the
door off and I do not notice any difference in IAS. Spitfires had no inner
doors!
