Singapore’s ST Engineering displayed its DrN-35DH unmanned aircraft system (UAS) at the Singapore Airshow 2024 held from 20 to 25 February.

The DrN-35DH is an intelligence, surveillance, and reconnaissance (ISR)-capable hexacopter and is a larger derivative of the company’s in-production DrN-15 unmanned aerial vehicle (UAV).

According to the company, the DrN-35DH features improved safety and precise location-tracking capability compared with the DrN-15 enabling the UAS to operate in ‘high-risk’ or densely populated environments.

The UAS features six arms primarily constructed of carbon fibre composite material. The propulsion system comprises six electric motors mounted at the end of each arm and each motor drives a two-bladed composite propeller.

The UAS has a maximum take-off weight of 37 kg, a maximum payload capacity of 5 kg, a maximum endurance of 37 minutes, and a maximum range of 15 km. The UAS can fly up to a maximum speed of 10 m/s and can sustain flying in windspeeds up to 10 m/s.
