COMBO

Combo is the outcome of the conversion process carried out by United Vehicle Robotics. We transformed manned coaxial helicopters Ka-26 into airworthy unmanned aircraft systems. Due to its unprecedented load capacity, the Combo is the leader among all civil unmanned helicopters.

Its modular design offers multi-functionality. A cargo can be transported on an external mount, inside the cabin, or docked to a helicopter as a removable module.

Resistant to severe weather, the Combo can fly even when a manned helicopter may find it too risky or impossible.

Computer vision expands the functionality even further and enables flights without GPS, by using obstacle detection and avoidance, and safe landing zone detection.

Development Status

The 1st Combo carries out flights in automatic mode starting from June 2019. In 2020 it was upgraded to the version 2.0.

As an airworthy unmanned aircraft, the drone successfully passed payload tests with 860 kg including fuel. In addition to cargo transportation, it sprayed 300L of water as in a real firefighting operation or aerial chemical works.

The 2nd Combo, which includes all model improvements, goes into its testing stage in Q1 2021.
