VELOS V3 D-FEND
Product descripton: VELOS V3 D-FEND by Velos Rotors
As a testament to its dual-use versatility, our Velos V3 platform is complemented by a dedicated defense – government edition, the Velos V3 D-FEND.
Building on more than 10 years of reliable service and hundreds of units deployed worldwide, this defense variant emphasizes advanced modularity, redundant safety features, ruggedized performance, and the ability to operate in GPS-denied environments, all of which are attributes highly valued in demanding military or governmental missions.
Fully Redundant Twin Transmission Design
Unlike most UAV helicopters that are built with common hobby-grade parts, the Velos V3 D-FEND was designed from scratch with three core objectives:
Simplicity, Efficiency, Reliability.
Leveraging the same patented, innovative twin-transmission design as the Velos V3, it allows for mission continuation even in case of mission-critical failures. Therefore, the Velos V3 D-FEND ensures operational reliability under the most challenging and uncertain conditions.
More specifically, it is capable of tolerating a complete failure of critical components, including motor, ESC, belt, gears, bearings, main battery and servo, while still enabling a safe landing to protect both payload and surroundings under those circumstances. The system automatically isolates the faulty component without introducing additional drag to the operational part of the drivetrain. Furthermore, the key advantage of this configuration is that all critical components operate at only 50% of their maximum capacity, making the Velos V3 D-FEND a highly dependable platform for critical missions.
A mature UAV solution for government and defense needs
The defense edition of Velos V3 has been recognized as a leading example of a dual-use system at high-profile Defense Innovations events organized by NATO partners and, over the last decade, it has already demonstrated strong and reliable performance in government and military applications. Tactical applications include, but are not limited to, intelligence, surveillance, and reconnaissance (ISR) systems, magnetic mine-detection payloads (STANAG-compliant), offshore surveillance missions, including deployment by the South Korean Coast Guard, proactive forest patrols and sensitive human organ transport in the U.S. These case studies underscore the ability of the Velos V3 D-FEND to meet stringent defense and governmental requirements with precision, resilience, and adaptability.
VELOS V3 D-FEND PAYLOADS
While the Velos V3 D-FEND has already shown strong capabilities in defense, ISR, and logistics missions, its potential extends far beyond these domains. Its robust design, long endurance, and modular architecture make it suitable for a wide range of public safety and humanitarian applications. For instance, it can carry thermal and high-resolution cameras to support search and rescue operations, enabling teams to assess disaster zones and locate survivors in difficult terrain. Its versatility also allows integration with various sensors, making it useful for environmental monitoring, border patrol, and firefighting support by providing aerial surveillance and real-time data to ground stations and teams.
Payload Over the Rotor (POR)
The Velos V3 D-FEND also provides a unique capability of carrying a Payload Over the Rotor (POR), allowing end-users to install payloads, antennas, sensors or a parachute above the main rotor system. This is also the ideal place for GNSS antennas for Lidar surveying. The POR is located on the center of gravity (CG) axis, so any payload integrated there does not affect the CG or other flight parameters.
Furthermore, the unobstructed 360º and sky views allow different configurations, such as a 360º panoramic view camera or a dual camera (one on the POR and the second one below the helicopter main body). This capability makes the Velos V3 D-FEND the ideal system to perform seamless ISR operations in high-difficulty areas.
You Trust. We Defend.
With thousands of flight hours accumulated across the globe, the Velos platform has matured into a trusted and reliable solution. As the demand for multi-role UAVs grows, the Velos V3 D-FEND is ready to meet emerging needs across a broad spectrum of governmental and defense applications, including police operations, medical supply transport, humanitarian aid, and emergency response.
