The VT-45 unmanned helicopter features a conventional configuration with main and tail rotors, and is designed for monitoring water areas, conducting search and rescue operations, patrolling and counter-terrorism activities, ice reconnaissance, relaying radio signals and delivering cargo.

The VT-45 is 2.66 metres long, its maximum takeoff mass is 45 kg, the payload mass is 10 kg, and it can fly for 2.5 hours. The VT-45 can reach speeds of up to 75 km/h, its service ceiling being 2,000 metres. The maximum flight range (with return to the initial point) is 60 km. Flight along the route can be carried out either automatically or manually with automatic stabilization.

The UAV can be additionally equipped with ADS-B In Out surveillance equipment for monitoring by a remote pilot and flight director in accordance with the ICAO standard (DOC 9816 AN/448).

Also on display at the exhibition was the VT-440 UAV (opening photo), capable of carrying up to 100 kg of payload. The drone is controlled and information is exchanged using a ground control station (GCS), which is part of the UAV system and can be supplied to the customer in various versions. The standard system consists of a VT-440 UAV with a cargo module and a GCS based on a 20-foot container.

The main tasks of the VT-440 are cargo delivery, water area monitoring, search and rescue operations, patrolling and ice reconnaissance. The maximum takeoff mass of the UAV is 450 kg, maximum endurance being 5 hours. The cruising speed of the drone is 120 km/h, while service ceiling is 2,300 metres. The maximum flight range with return to the takeoff point is 300 km. It can fly either in manual or automatic mode. The airframe length with open blades is 7.05 metres; it is 1.5 metres wide and 2.35 metres high.

The VT-440 is powered plant by a Rotax 914L opposed 4-stroke 4-cylinder internal combustion engine, providing a power of 115 hp. The system includes a VT-440 UAV with a cargo module and a GCS based on a 20-foot container.

Another drone, the VT-30E, was presented at the stand of “Radar mms”. It is equipped with an electric motor and a large capacity battery. The UAV can be supplied with GCS in several versions, or complete with an automated Dronoport docking station. The latter allows for fast battery charging and provides UAV storage and takeoff and landing operations.

The VT-30E can be used for territory monitoring, search and rescue operations, patrolling, counter-terrorism operations, ice reconnaissance and cargo delivery. The device can act as a radio signal repeater.

The maximum takeoff mass of the drone is 30 kg, while payload is 7 kg. The UAV can fly for up to 1.5 hours with a cruising speed of 55 km/h. The operational ceiling is 4,500 metres. The maximum flight range with return to the takeoff point is 40 km. The UAV is 2.815 metres long, 0.53 metres wide and 0.54 metres high.

All unmanned helicopters developed and produced by “Radar mms” JSC, accept the following equipment as payload: optical-electronic systems, magnetometric and radar systems (including those developed by the company), various detectors, gas analyzers, etc.

The flight of those UAVs is performed in programmed automatic mode or in remote-controlled mode with automatic stabilization.

The “Dronoport” station was also visible at the “Radar mms” stand. Capable of operating autonomously, it is equipped with a heated sliding roof, a platform for UAVs takeoff and landing and an intelligent battery charging system. “Dronoport” allows UAVs to operate both in urban environments and in remote areas. It includes a charging station, a weather station, a climate control module, an IR illuminator, two external and two internal cameras, an uninterruptible power supply and a communications module.
