Recently, Sara airlines, a subsidiary of Russia's Kalashnikov group, announced that its new hybrid fixed wing UAV has conducted long-range flight test for the first time. In this test, the UAV flew for more than 12 hours and a flight distance of 1130 kilometers. Russian military experts pointed out that due to the use of hybrid system, the UAV has a flight distance of more than 1000 kilometers, can carry out reconnaissance in depth to the enemy, and is not easy to be found. New Russian fixed wing UAV First hybrid UAV Itar TASS reported that Sara Airlines said that at present, most UAVs in the world belong to all electric multi axis aircraft, and this UAV integrates motor and internal combustion engine and uses hybrid power device to greatly increase the endurance time of UAV, which can exceed 16 hours at most. It is understood that the UAV is the world's first long-range UAV equipped with motor and internal combustion engine without airport takeoff and landing. It will be mainly used for reconnaissance missions. It can be equipped with target interception system, communication relay system and mobile network monitoring system to perform radio technology reconnaissance, mobile phone identification and positioning tasks. In addition, the UAV is also equipped with a new airborne visual navigation system and Intelligent Airborne processing system. It does not rely on satellite navigation. It can fly in radio silence, decode terrain and identify objects, automatically detect and identify targets from multiple directions during flight, and receive the latest information such as the number and location of targets. Nikita hamitov, special project director of Sara airlines, said that the new fixed wing UAV has a flight speed of 80 km to 140 km per hour, is launched by catapults, and is equipped with parachutes and shock absorbers for landing. Depth reconnaissance Russia today website reported that Russian military expert Victor baraniez said that the UAV has a flight distance of more than 1000 kilometers, indicating that the aircraft can sneak into the enemy's strategic depth area for reconnaissance. In case of armed conflict, the high-definition thermal imager and high-definition camera equipped with the aircraft can help it carry out in-depth reconnaissance missions, which is extremely important for the Russian army. In the future, if it is further refitted into a long-range attack UAV, it will greatly improve the strike capability of the Russian army. Sergei hatlev, former head of the Russian air defense missile force, said that the main advantage of this UAV is that it can store more fuel to stay in the air for a longer time. At the same time, the aircraft uses hybrid power, which is not easy to be found by the infrared detection system, and the concealment is greatly improved. (Liu Yupeng) (outlook new era)
