Common Questions About the HT-100

What is the ANAVIA HT-100?

The ANAVIA HT-100 is a Swiss-engineered unmanned VTOL helicopter with a 120 kg maximum take-off weight, 60 kg payload capacity, and 6-hour flight endurance. It uses a Flettner intermeshing rotor system — two counter-rotating main rotors with no tail rotor — powered by a 15 kW shaft turbine burning JET A-1 fuel at just 9 litres per hour.

How does the Flettner rotor system work?

The Flettner system uses two intermeshing main rotors spinning in opposite directions. This eliminates the need for a tail rotor, which means 30% more energy goes to useful lift instead of countering torque. The result is longer endurance, higher payload capacity, and significantly lower vibration — critical for stabilized sensor optics during ISR missions.

What fuel does the HT-100 use?

The HT-100 runs on standard JET A-1 aviation fuel, with JP-5 and JP-8 available on demand. Unlike battery-powered drones that lose capacity in cold weather and require hours to recharge, the turbine engine delivers consistent performance from -25°C to +55°C and can be refuelled in minutes for immediate redeployment.

What payloads can the HT-100 carry?

The HT-100 supports modular plug-and-play payload integration via its avionics bus — swap any sensor in under 15 minutes. Compatible payloads include EO/IR surveillance cameras (67x optical zoom, cooled MWIR thermal), wide-area search sensors, LiDAR mappers, hyperspectral/multispectral imagers, emissions detection systems, COMINT equipment, 100MP RGB cameras, and cargo boxes up to 50 kg / 90 litres.

How far can the HT-100 fly on a single mission?

The HT-100 has a maximum mission distance of 600 km with a data link range of up to 200 km using terrestrial radio. With optional LTE or SATCOM connectivity, the control range is effectively unlimited. At cruise speed of 100 km/h, it can sustain 6 hours of continuous flight with a 14 kg payload.
