The heavy transport unmanned aerial aircraft of the ultra-short take-off and landing “Partizan” has completed the first stage of flight testing. The UAV is based on the TVS-2MS aircraft. The flight of the heavy UAV lasted 20 minutes at an altitude of 200 meters at speeds from 50 to 200 kilometers per hour. During testing, a pilot was in the cockpit to monitor the parameters. An aircraft with a drone function was developed at the Siberian Aviation Research Institute named after Chaplygin. The Partizan UAV is designed to transport cargo and can be used for civil and military purposes. The Russian Partizan UAV is equipped with a hybrid propulsion system and can take off and land on a site measuring 50 by 50 meters, with obstacles at the border of the site up to 15 meters high. The flight range of the Partizan UAV is up to 1 thousand kilometers, at an altitude of up to 8000 meters with a maximum speed of over 300 km/h, payload weight of up to one ton. As reported, the Partizan unmanned aircraft will be 100% made in Russia. In 2024, it is planned to deploy a production complex and produce 10 serial copies of the Partizan heavy UAV.
