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.

1. Engine control

  • Throttle​
  • Cowl flaps

In your UAV 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.

2. Control surfaces

  • Aileron​
  • Elevator
  • ​Rudder​
  • Flaperons​
  • High lift surfaces

With Volz Servos you can rely on all control surfaces immediately and precisely reacting to all remote steering commands. For safe UAV operation in all areas.

3. Payload

  • Cargo doors​
  • release mechanisms

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

1. Swashplate control

Volz Servos ensure the reliable and safe control of the swashplate below the rotor of your helicopter. The actuators realize the attack angle of the rotor blades and thus the flight direction of the helicopter

2. Tail rotor​

  • Tail rotor​

The tail rotor stabilizes your helicopter by generating lateral thrust. Volz Servos ensure the reliable control of the tail rotor and the perfect interaction with the rotor – for precise maneuvers in all situations.

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.

Why Volz Servos for your UAV?

First of all - matching YOUR needs

Our wide product range covers most cases of possible applications. Beyond that, we modify existing standard actuators or develop completely new customized solutions – as fast, flexible and agile as the aerial vehicles they are made for!

Wide range of products and options

The Volz standard actuator portfolio offers sizes starting with the full brushless DA 15-N to the DA 58-D, the so called “Beast”, with various features such as health monitoring, fully brushless technologies, various interfaces etc.

Certifiable

With Aircraft Electronic Engineering (AEE), Volz Servos acquired an EASA approved production (Part 21G), maintenance (Part 145), and alternative design organization (Part 21O) in 2021. So Volz Servos meet the future requirements of the market for certifiable actuators!

Competent consulting

Discuss your requirements with our experts and learn how Volz develops your customized servos – or what kind of servos we can offer off-the-shelf.   

Trusted

With nearly 40 years of experience in air mobility, Volz is best known as the leading manufacturer of electromechanical actuators for aerial vehicles.

Reliable and Redundant

Volz Servos impresses with its compact design combined with maximized actuating force, reliability and durability thanks to high-quality materials, technology and processing. The dual-channel design of the redundant Duplex Servos enables continuous operation, even if one of the two channel should fail.

Guaranteed quality

Our actuators are tested for several thousand hours of use. We manufacture them in Germany under the strictest quality controls (ISO 9001:2015, EN 9100 under implementation) to ensure the high requirements for quality and functional safety.

Monitoring

Various electrical interfaces offer the possibility of monitoring the operating status / health of the servo, for example by reading out the current, internal temperature, air humidity and more.
