• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

Does anyone know where one would start to calculating the loads on a crank shaft during snap rolls?
I have the cad file and material type of a radial engine crank shaft I would like to know just what its limits would be and if it would handle a life of regular snap rolls.
I imagine the aircraft weight and propeller weight and diameter would form part of these calcs.
I have access to some engineers with solid works that could go modeling but I would need to tell them the kind of parameters to set.
I’m not even sure it’s something that can be done, just throwing it out there to see what the knowledge base comes back with.

Cheers for reading

Dom
