Skydweller and Volz announce Technology Partnership

Multinational aerospace start-up Skydweller and industry servo leader Volz partner to develop and deploy next-generation actuators.

Skydweller Aero Inc., an international aerospace company headquartered in the U.S. developing unmanned solar powered aircraft for defense and commercial industries, today announced its partnership with Volz Servos, a privately-held company developing electronic actuators for the aviation, aerospace, robotic, automotive, and medical industries. This partnership is focused on the development and deployment of a next-generation electro-mechanical actuation system for the Skydweller platform.  

An initial collaboration was made in 2020 whereby Volz Servos DA-58 and DA-30 product line was selected to support Skydweller’s first autonomous flight. With the support of AESA (Spanish Aviation Safety and Security Agency), the Skydweller platform was granted an experimental airworthiness certification, enabling the company to successfully test its new, proprietary fly-by-wire (FBW) actuation control system. 

“Volz Servos has a long-standing reputation for quality in the aerospace industry. Their product line offers dual redundant technology which aligns perfectly with our overall strategic focus on developing extreme reliability through redundancy. This is key to achieving our goal of perpetual flight,” said Skydweller CEO Dr. Robert Miller.  “We see this partnership as enabling delivery of Skydweller’s unique value proposition to our current and prospective customers.” 

The Volz actuators in the Skydweller aircraft move the control surfaces: The DA-58 Duplex is used for the ailerons on the wings, each of which is around 35 meters long, while DA-30 HT Duplex are installed on the horizontal and vertical stabilizers of the aircraft. .  

“We are delighted to partner with a visionary aerospace start-up like Skydweller which has set extreme reliability and redundancy as their number one goal in achieving persistent flight. This vision mirrors our core business and product strategy,” said Volz Servos CEO Phillipp Volz. “Our collaboration on the testing and integration of our DA-58 and DA-30 dual-redundant actuators achieved a company first: the utilization of our product line tied to a human-rated safety-critical airworthiness certification. We look forward to continuing our collaboration with the innovative aerospace engineers and technologists at Skydweller.”   

Currently, Skydweller Aero and Volz Servos are working on the next level of their collaboration leveraging their collective engineering prowess to design lighter, more efficient and ultra-reliable actuators, enabling continued performance gains.
