Aviation application example: precision landing for flight safety.

The high-lift system controls the slats and landing flaps in an aircraft in order to shorten the distance required for take-off and landing. If the main hydraulic system fails, the electro-mechanical backup system is used.

SPN supplies individually developed planetary gearboxes and gearing components that meet the highest requirements: In addition to low wall thicknesses for a weight-optimized design, form-fit connections with high safety factors and absolute corrosion resistance are also important. The strictest test procedures and complete documentation of all steps from material procurement to production and transportation guarantee maximum safety in this highly sensitive area.
