Pegasus collaboration with the tactical UAV designers from AUTH,

Greece has entered a new era in the design, development and production of Unmanned Aerial Vehicles. The Aristotle University of Thessaloniki (AUTH) and its Laboratory of Fluid Mechanics & Turbomachinery (LFMT) was a pioneer and a key player in this effort, starting with the HCUAV RX-1. With a rather conventional, boom-mounted inverted V-tail configuration, the RX-1 made its maiden flight back in 2016. 

Shortly after, the LFMT made a breakthrough by initiating two new, UAV-design related projects: The DELAER RX-3 and the MPU RX-4. The RX-3 is a tactical UAV that will be able to cover large-scale surveillance missions and swiftly deliver 50kg of useful payload via airdrop in times of crisis or rescue missions, whereas the RX-4 is a micro, versatile UAV that will be able to cover surveillance-related missions at almost any terrain using its novel VTOL and hovering capabilities.

The three robotic unmanned airborne systems, RX-1, RX-3 and RX-4, were presented at the Thessaloniki International Fairs (TIFs) that took place in 2016, 2018 and 2019, respectively.

Pegasus Actuators supplied the control surface actuators for those systems.

Professor Kyros Yakinthos, Director, Laboratory of Fluid Mechanics & Turbomachinery Department of Mechanical Engineering, Aristotle University of Thessaloniki had this to say about us: 
"Thank you guys! I really appreciate your support and your will to help us!"

DSDI  - Drones et Systemes de Drones Innovants S.A.S., decided for Pegasus PA-R-135-4 type servo actuators

April 2016


Mr. Emeric Sergent of DSDI has this to say about Pegasus.


"Our DSDI engineering team was investigating for the perfect servo actuators to match the design criteria of the current UAV project. Pegasus PA-R-135-4 type servo actuators therefore were the best choice to achieve reliable service under the most adverse conditions.

They present small form factor, high dependability implementing safety functions such as overload protection, high grade interface using RS485 data protocol, differential position feedback and high ingress protection rate at IP67 level."


"That is why DSDI has chosen Pegasus to equip their UAV product range with their latest technology."

August 2015

Mr. Yeong Hur of Georgia Insitute of Technology informed us about the
"Adaptive robotic helicopter landing gear", a system that can handle
touching down in unaccommodating environments.

Until the legs can be tested on a full-size helicopter, Georgia Tech is
perfecting them on their GT- Rotor BUZZ, a large unmanned helicopter.
Here it demonstrates a landing that would be completely impossible for
conventional helicopters.

These legs operate independently of each other, and each one has an
embedded distance sensor to measure how near it is to the ground. They
automatically put themselves in the perfect position to make a smooth,
level landing every time. When not in use, the legs fold up and out of
the way.

The control actuation of the vehicle has exclusively been supplied by
Pegasus Actuators GmbH

Since 2009 we have been in contact with the Vanilla LLC development team. Now in March 2015 we received a call from co-founder Jeremy Novara saying „Well we finally did it“  

All aerodynamic surfaces of the Vanilla ULE unmanned aircraft are controlled by Pegasus  PA-R-250-8 and PA-R-205-4  type actuators.

Falls Church, Virginia, March 2, 2015. On February 25,  the VA001 Unmanned Aircraft System successfully completed it´s maiden flight. The 36-ft wingspan Ultra-Long Endurance (ULE) aircraft has been  designed to fly missions of up to 10 days. The aircraft (N240HR) launched carrying an 18-lb simulated payload and sufficient fuel for a 24-hour flight. Powered by an efficient heavy-fuel engine, the UAS flew autonomously under a Certificate of Authorization (COA) in the national airspace at altitudes up to 6000 feet MSL before landing, meeting all test objectives. “Today, the team’s hard work really paid off – the airplane flew beautifully and showed all the performance we expected. This maiden flight test provided validation of the VA001 design and its remarkable capabilities.” stated Neil Boertlein, co-founder and Chief Engineer for the VA001.

October 2014

In 2014 we received an order for a small batch of redundant duplex actuators for one of our customer´s optionally piloted (air) vehicles (OPV)

We combined two PA-R-340-9-R-24-C type actuators with our unique pc-board arrangement and two magnetic clutches. The result is a redundant actuator assembly that can optionally be engaged or disengaged by the pilot in order to operate the aircraft either as a uav or conventionally piloted.

The entire development, design, realization, assembly and testing was performed by Pegasus Actuators GmbH within a time frame of 4 months from date of purchase order to shipping date!

Pegasus Actuators to support french EOLE program

September 2013

The Eole airborne demonstrator is a development coordinated by ONERA, it is part of the Perseus student program, CNES being the contracting authority. The demonstrator is a scaled model for 


Eole airborne launching demonstrator model in the throat of Onera´s L2 wind tunnel

This scaled model (1/2.2) is evaluating the flight dynamics, there are plans for rocket launches to take place in a specialized facility by the full version. It is fully autonomous apart from the take-off and landing and it operates within a 30km range. The demonstrator has a wingspan of 6,7 m, a weight of 100 kg and a payload of 50 kg. It can fly up to 8000 m (~26k ft) with maximum speed of 0.6 mach. It can drop its payload at 4km while flying at 0.2 mach. The demonstrator aircraft in the pictures has been designed and manufactured by well known french aerospace contractor Aviation Design (http://www.aviation-design.fr) Eole is propelled by two AMT Titan turbojet engines. All contol actuators have been supplied by Pegasus Actuators Gmbh, manufacturer of high reliability industrial servo actuators.

Now that´s one big scale model aircraft !

August 2013

Christian Wolf and Uwe Grevsmühl went for the big stuff when they decided to turn a real „L-Spatz“ glider aircraft made by German manufacturer Scheibe Flugzeugbau GmbH in 1959 into an RC airplane. For to get airborne the guys installed a 3W 4 cylinder 45 hp engine.

Christian Wolf and Uwe Grevsmühl in front of the L-Spatz

For contolling the gentle giant they rely on 7 units of our Pegasus PA-R-340-7-C-24-A-180-30 servo actuators which handle the required torque of 7 – 12 Nm to operate the aerodynamic surfaces without effort.

The Emcotec company designed a customised power supply on aviation industry safety level.

„We will perform several demonstrations like aerodrome circling flights during international flight shows..............no aerobatics- just for the fun of it“ says Uwe Grevsmühl.

We at Pegasus say „Break a leg“ and we keep fingers crossed for the two likeable aviators.

The Warsaw Institute of Aviation launches the Phoenix solar powered stratospheric UAV. Pegasus actuators play an essential part in this demanding project.

October 2012

Phoenix is a unique combination of extreme flight duration and stratospheric operating altitude with no regulations limiting the flight route. These capabilities turn UAV into a compelling flexible complement to existing satellite, aerial, terrestrial assets for data acquisition.
