Stabilizer subsystem

The directional gyro, torque motor, clutches and indication linkage carried by the stabilizer housing.

The directional gyro supplies the reference. The brush/sector and torque drive correct the cardan’s relationship to its surroundings.

Separate clutches couple this reference to the sight and autopilot/P.D.I. linkages.

Geometry follows the cited drawings and photographs. Unmeasured dimensions remain approximate; exploded spacing reveals existing model groups rather than a prescribed disassembly procedure.

Parts in this component

PART · PAGE 25

Directional gyro unit

The electrically driven rotor, its bearings and motor fittings, enclosed by a ribbed case. The whole case can tilt inside the cardan while the rotor spins within it.

PART · PAGE 25

Directional gyro cardan

The cast support frame, upper and lower gudgeons, ring gear and four slip rings surrounding the directional gyro unit.

PART · PAGE 25

Precession and counter-balance bails

The case-mounted precession and counter-balance bails, together with the actuator that passes through the lower cardan gudgeon.

PART · PAGE 26

Torque motor and magnetic clutches

Two opposed drives and their magnetic clutches provide corrective rotation to the stabilizer cardan.

PART · PAGE 22

Bombsight clutch

A slipping coupling between the directional reference and the sight, operated by a collar, lever and spring linkage.

PART · PAGE 22

Autopilot clutch

The separate slipping coupling associated with the autopilot and Pilot Direction Indicator linkage.

PART · PAGE 23

P.D.I. brush and drift clutch

The resistance unit, stabilized brush, sight-stem bushing and drift-clutch arrangement shown together in the manual cutaway.
