Fully Redundant Proven Design

UAV Helicopter Drone for UAV LiDAR Inspections and UAV Cargo Delivery

Safety • Redundancy • Efficiency • Performance

The IP65-rated, fully redundant design of the Velos V3 allows for a high-capacity payload and multi-sensor options making it a reliable UAV helicopter option. The design of the Velos V3 with its powerful twin-motor drive train and 30-mile control range offers reliability and scalability for any civil or commercial application. The payload over rotor (POR) option also allows for the addition of a ballistic parachute or other sensor options. The V3’s stable governor logic has CAN bus support, which has been tested exhaustively with Here2 and Here3.

Fully Redundant Twin Engine Design

Velos’ core innovation is its twin-engine fully redundant design. There are two sets of every significant component including the main motors, batteries, electronic speed controls (ESC), belts, and gears. Unlike most UAV helicopters that are built with common hobby-grade parts, we designed the Velos V3 from scratch with three main objectives: safety, efficiency and reliability.

The patented highly innovative drivetrain gearbox renders Velos V3 the only UAV helicopter in its class with the ability to tolerate a complete failure of most major components allowing it to safely land and protect its payload and surroundings under those circumstances. The system automatically isolates the faulty part without introducing additional drag to the operational part of the drivetrain.

The Velos V3 can tolerate many types of failures including motor failure, a broken belt, gear–one–way bearing failure, burned ESC, main battery failure, BEC failure or servo failure.

Multiple Control Options

The Velow V3 has many control options and supports both classic radio TX and a joystick connected to the ground control station. Additional control options include 4G, 5F, Silvus StreamCaster and others. In Here3, that specific GPS is RTK-ready, which means that without any further change to the aircraft, we can add the ground RTK system and operate with RTK accuracy.

Ready for Extreme Conditions

The Velos V3 is IP65-rated against ingress of solid foreign objects and water, which allows it to safely fly in rain, snow or dust. It also allows for the addition of more laser altimeters operating simultaneously and is equipped with obstacle avoidance sensors and follow me features.

[The Velos V3 has been] truly tested in the most extreme conditions.”
