I like the idea of testing a airframe for strength before actually commiting the beast to the air. Does anyone know how to calculate the forces involved and where on the airframe to apply these forces? Obviously(?) a 3lb plane pulling 4G will have to sustain a force of 12lb, but where on the plane do I hang the appropriate number of bags of sugar and where do I suspend the airframe from? tta, Keith.

Don't know the details but in most cases the inner third of the wing usually carries 90% of the stress. Tom | |||||
540.2 | What about the tail? | RDGENG::NODDLE | Keith Noddle - CSSE, Reading, UK | Fri May 13 1988 09:52 | 8 |
Thanks Tom. That obviously indicates that I don't suspend the 'plane by the wing tips! What about the force on the fuselage between wing and tailplane - after all, the tails must generate some lift and therefore put the fuselage under lateral strain... Keith. | |||||

Keith, The April 1987 issue of Model Aviation has an article that talks to G force calculations, etc... If you don't have it, send me mail and I'll copy the article. Hope this helps, Brian |
