main landing gear

Postby BigJim » Wed Dec 24, 2008 7:24 am

One of the most complex equipement of the Corsair is its landing gear. After getting factory drawings I tried to put it on 3D-CAD. Here is the result (sorry, comments are in german).

Finally you can get here the description of the oleo strut (oleo-pneumatic type).

Last but not least: 4 diagrams of filling procedure (oil & air) into the oleo strut.
I hope that any user can add similar posting on this page, just to share knowledge! For instance, I'm searching for a factory drawing of the cowling shape (F4U-1x-versions) including the cowlflaps.

Just to have an idea how much efforts are necessary to produce a landing gear like that, here the part list.

Absolutely fantastic, great drawings. The very 2 first oleo strut drawings I'd use for my CAD-model four years ago.

At first: the hinge, links and joint points. The second drawing shows the movement (5°-steps).

Jim that looks fantastic. Would you know how I can get a set of blueprints.drawings for the tail assembly, retract unit, dashpot and the hook.

I have recently started playing with Autodesk Inventor and would be very interested in desinging tail assebly for the F4U (any variant would do). I intend to have full animation and one day build a flying model.

Warm Regards,

Thunder

hi
I've got a quick question.
and how to set the cache on the landing gear.
and how it is positioned when the landing gear out.

Thank you
Chris

Hello Thunder,

a very good address to get blueprints as µ-films is the Smithsonian National Air and Space Museum; Archives Division. Round about USD 30,- each role with nearly 600 drawings. To find out what you need I recommended to by the index before.

Hey the illustrations of the strut look great, but i'm confused by something.

Looking at the illustration, one is led to believe the the strut trunnion somehow attaches to the wing spar. i believe this is not the case.

Looking at other illustrations of the wing structure, i believe there are two ribs that extend forward and ahead of the wing spar and angle inward.

At the forward extremity of these ribs, there is a trunnion bearing, around which the main shock strut pivots. i think the actuator and drag links may connect directly to the front face of the spar, but i think the main trunnion is well forward of that. The "Trunnion Ribs" are delineated by the angled rows of rivets located either side of the "spade" door cutout in the lower wing skin, and adjacent to the inboard trunnion rib is the ducting for the oil cooler and induction air inlet (s).

I believe when the main landing gear retracts, the strut nestles into a "dip" engineered into the lower surface of the spar. Not unlike the landing gear strut on the Later Martin AM Mauler.

I know the emphasis is on the strut itself, but the location geometry is important too. My intent is simply to clarify a detail thats a little vague.
