ABSTRACT:
A cup shaped disc (13) consisting of a central portion (20) having radially extending blades (18) is attached with its central portion to the protruding hub portion (12) of a radial flow turbine wheel (2) consisting of a backing plate (10) extending transversely to its rotational axis (7) and having axially protruding turbine blades (11) in addition to the protruding hub. At high rotational speeds this disc (13) will tend to straighten out, whereby the effective portion of the turbine blades will be reduced and the increase in the rotational speed restricted. This is of importance in ram air turbines for missiles.
