Rg{Mr Rowledge}/Tsn3/LW.15. 1. 30 MODEL TEST CRANKS Further to Rg{Mr Rowledge}2/LW.20./12. 29, we are so convinced of the importance of testing hardened crankshafts in aero engines that we wish to try fatigue tests on three further models in air hardening steel, Firth's A.H.G. Please put these in hand. They should be models of the modified crank DES.989, as shown on DES.995. Rg{Mr Rowledge}/Tsn. | ||
