Uncrewed aircraft indispensable for future logistics

Volz delivers certifiable actuators
small and strong enough
for drone demands

The current and future applications are countless

Uncrewed Aerial Vehicles – drones – are just starting to show their possibilities. They can be navigated with impressive precision and coordination – made possible with components that guarantee reliability and perfect control, combined with light-weight design. The safety requirements for professional UAV applications operating in civil airspace correspond to those of regular planes and helicopters.

So when it comes to choosing components during the development phase, it’s crucial to use trusted, reliable and certifiable parts for ultimately also receiving the certification required for operation. That’s where Volz Servos comes in.

"The combination of small actuators for the UAV industry, high quality and reliability, certifiability and our experience and agility makes Volz Servos unique in the market."
Mark Juhrig, CTO Volz Servos

Current and future applications for professional UAV

  • Delivery of medical or technical materials within large clinical complexes or factory grounds or to remote areas
  • Urban delivery
  • Control, cleaning and maintenance of inaccessible areas or in dangerous environments
  • Reconnaissance missions
  • Observation and surveillance
  • Police, fire brigade and military applications

The numerous existing laws and regulations on civil airspace at regional, national and international levels are subject to constant adjustments, especially with regard to the handling of uncrewed aerial vehicles. Even the smallest professional drones, maybe for last mile logistics or intralogistics, navigate and operate in civil airspace. With more than 40 years of experience, Volz speaks the language regarding these requirements and helps companies becoming fluent – with offering certifiable actuators for all kinds and sizes of drones in cooperation with our subsidiary AEE.

Certification is currently the biggest topic in the growing UAV sector. We at Volz Servos questioned ourselves how to maintain relationships with our customers beyond the prototype stage. With our subsidiary AEE, an EASA approved production (Part 21G), maintenance (Part 145) and alternative design organization (Part 21O), we are in the best position to meet our customers' needs – especially when it comes to certification, DO 178C, DO 254 and DO 160 requirements. Volz can take into account and comply with all regulations – so our actuators play an important role at the safe integration of UAV in civil airspace.

3. Engine control

  • Throttle
  • ​Cowl flaps

In your helicopter engine, Volz Servos provide the precise and safe control of throttle and cowl flaps. So you are always in control of the demanded engine performance and operating temperature.

4. Payload

  • Cargo doors
  • release mechanisms

Reliability of cargo doors and release mechanisms are crucial for safe and cost-effective operation of UAV helicopters for delivery. Volz Servos ensure quick loading and unloading, secure fixation and precise cargo dropping.

A standard Volz actuator with special custom-made adaptions makes the Airboxer the most reliable concept that High Eye has ever created.
Marijn van de Ruit , High Eye CTO

High Eye designed the Airboxer VTOL UAV to get in and out of locations out of reach for other systems: to collect valuable data or transports goods up to a payload of 7 kilograms.  

A standard Volz actuator with special custom-made adaptions led to an extremely reliable aircraft. “The numbers don’t lie: The amount of non-recoverable incidents has never been lower”, says High Eye CTO Marijn van de Ruit. 

“We are pleased with our now more than 15 years of good collaboration with Volz Servos, which included over 3.000 customized actuators for Schiebel’s S-100s. The Volz DA 26 are unmatched in reliability and crucial for our UAV projects enabling precise steering and safety.”
