Abstract

1388533 Driving and cooling electric generators KONGSBERG VAPENFABRIKK A/S 20 Feb 1973 8364/73 Heading H2A [Also in Divisions F1 and F2] The invention relates to a method of supporting the rotating assembly of a turbine driven electric generator in a missile. The rotating assembly comprises a shaft 2 on which is mounted a ram air turbine rotor 3 and the rotor 1 of the generator, the assembly being disposed within the nose-cone 7 of the missile, the nose-cone being formed with an inlet opening 8 for inflow of ram air and with openings 18 for discharge of the air from the turbine. The shaft 2 is formed with a through-bore 14 and is rotatably supported within fixed structure by forward and rearward ball-bearings 4, 5. A pair of spring washers 10 is disposed between the rotor 1 and theinner race of the rear bearing 5 whereby upon initial acceleration of the missile at launch the rotor is forced by inertia against the stator part 15, the rotor assembly moving forward to the position shown when the acceleration ceases. Ram air flows through the bore 14, and reverses in direction in the chamber 16 to flow forwardly through the rear bearing 5, past the rotor 1, through the forward bearing 4, through the radial space 17 at the rear face of the turbine rotor 3 and discharges through the openings 18. The air serves to cool and lubricate the bearings. The surface of the chamber 16 is formed with a projection 15<SP>1</SP> which assists the reversal of the air flow; any solid particles in the air flow are centrifuged at 16<SP>1</SP> so that clean air passes through the bearings.
