Application example in aviation: precision landing for aviation safety.

On an aircraft the high-lift system controls the leading-edge slats and the landing flaps to reduce the distance required when taking off and landing. If the main hydraulic system malfunctions, the electro-mechanical back-up system cuts in.

SPN supplies custom-designed planetary gear units and gear components for this system that meet the highest demands: Besides low wall thickness, important factors for a weight-optimised design are positive-fitting joints with high safety factors and 100% corrosion resistance.

Stringent test methods and seamless documentation of all steps from materials procurement to manufacturing to transport guarantee maximum safety in this highly sensitive field.
