Abstract

1357337 Turbines JOSEPH LUCAS (INDUSTRIES) Ltd 21 Oct 1971 [13 Aug 1970] 39036/70 Heading FIT [Also in Division F2] A brake to prevent overspeed of a turbine comprises a disc 15 of resiliently deformable material secured to the boss 14 of the turbine rotor 13, the disc being dished at 16 and having an enlarged rim 17 such that at overspeed centrifugal force causes the rim to engage a friction ring 18 retained in housing 10. In a modification disc 15 is replaced by a member having several radial arms.
