Marathon Day 19 – Landing Gear Kinematics

I spent most of the morning really digging into aircraft landing gear kinematics. Oh boy what fun! No seriously, it was fun. So I finally figured out how to build the gear so it can have a forward retraction point. Most gear of this type either just moves up and down (C5) or tucks inward in to the belly (777). I needed this to tuck in forward on the wing.

What I came up with is a variant of an Avro Vulcan  main gear in combination with a little XB-70a action.

Some changes to the mock-up I had before:

  • Tucked the dual wheel sets closer together
  • Moved the entire system forward and inward, because the gear trunnion didn’t set up in a believable place
  • Built up the brake system for each wheel set


Okay, now I’m off to APE (Alternative Press Expo)!

  1. Hi,

    Been visiting the site watching your progress [especially the vid of you at work] with mouth agape.

    Keep it up mate, excellent work here.

    needed help for a class (kinematics) have to write a report on design and analysis of aircraft landing gears (applying four-bar linkage) wondering if you can lean me in correct direction.
