Advanced Propeller Systems for Modern Aviation
Our propeller systems are designed to deliver exceptional performance, efficiency, and safety across a wide range of aircraft and flight profiles. Combining advanced materials, aerodynamically optimized blade geometry, and decades of engineering expertise, our solutions provide consistent RPM control, reduced vibration, and reliable thrust in demanding operational environments.
Whether hydraulic, electric, reversible, fixed, or ground-adjustable, each system is engineered to meet strict aviation standards and to support smooth, responsive performance from takeoff to landing.

Hydraulic propellers
Precision-controlled hydraulic systems for optimal RPM management in all flight conditions.

Our hydraulic constant speed propeller installations are certified as 2-, 3-, 4-, 5- ,6- and 7-blade models for engines producing up to 5000 hp, that have an hydraulic oil supply to the propeller controlled by a governor.
All our hydraulic propellers are optionally available with our patented feathering and /or reverse system and can be equipped with electric or alcohol de-ice boots.
The single piece hub is made from forged or solid aerospace aluminum alloy. It is corrosion protected and the hub's outside can be additionally painted for sea applications.
The blade bearings are special design ball bearings, where the balls act as split retainers for holding the blades into the hub, which creates an increased safety factor against blade loss.
The propeller construction has a simple and light-weight design without any unnecessary parts.
All weights required for static propeller balancing are installed on the front spinner bulkhead.
Presently most of our blades are built in natural composite design, by using high compressed thin layered laminated beech wood, which has a similar tensile strength as steel, in the root section and selected lightweight laminated spruce wood in the remaining part of the blade.
The wooden core is reinforced by layers of epoxy fiberglass, Kevlar® or carbon fiber and sealed by several coatings of acrylic-polyurethane paint.
An aluminum blade ferrule is attached to the blade root by using special design patented lag screws.
The pitch change of the blade is enabled by an excenter pin installed in the blade ferrule.
Propellers for aerobatic aircrafts or propellers built with feathering capability are equipped with counterweights, which are installed on the blade ferrule.
The critical section of the blade's leading edge is protected by a bonded on stainless steel erosion sheath.
The inboard section of the leading edge is protected by a self-adhesive PU-strip. All of the above makes the blade all weather operable.
The spinner dome is a single piece part made from fiber reinforced composite (Kevlar®).
It is extremely crack resistant as well as very light weighted.
The servo pressure necessary for changing pitch is generated by a gear pump located inside the propeller governor.
The propeller system is single acting.
An unfeathering accumulator, which is directly connected to the propeller governor, is optionally available for Feathering Propellers.
