Plate 10 Dunlop Precision is supplying high
specification seal for the Dowty propeller in the Hercules C-130J
The Dunlop Precision component acts as an oil seal governor which is mounted on the propeller gearbox. It consists of an aluminium backing plate bonded to a Viton moulding, which combines flexibility with excellent oil resistance.
The Dowty six-bladed R391 propeller for the Hercules C130J is an advanced swept blade design with all-composite blades and optimized ARAD-A aerofoil sections, giving low noise levels with excellent take-off and climb performance. It has a fail-safe electronic control system for precise speed selection and accurate control of synchronizing and synchrophasing.
