Anybody ever heard of the Heinkel He 222 - referenced in Pazmany's "Landing Gear Design for Light Aircraft", page 186.
I quote -
"The landing gear illustrated in Figure 10-121 employs a unique torsion spring arrangement. Four torsion bars are restrained from rotation at the top by means of knurled bosses pressure fitted to a plate. At the bottom end, the torsion bars pass through bronze bushings and extend below the cap which closes the leg. Four bellcranks are attached to the torsion bars. Each pair of bellcranks is interconnected by a short link. A tie rod at each side connects a bellcrank to the wheel fork."
"The gear was invented by Wilhelm Van Ness in West Germany and patented in Austria in 1952. The gear was used in a light airplane made by the Heinkel Company (He 222)."
I'm interested because this particular design seems to be more within the home builders' fabrication range than a pneumatic oleo strut. Any information on this aircraft/landing gear would be gratefully received - I can't find anything useful on the Web.
Regards
Tim
