USA tested modified ScanEagle hydrogen fuel cell UAV
ScanEagle drones are used by the US Navy and Marine Corps for reconnaissance and reconnaissance. The device allows you to receive data on the positions of the enemy, however, due to the use of a piston engine on it, it makes a lot of noise and can be seen from a long distance. This limits the applicability drone.
The use of electric motors allows to reduce the noise of unmanned vehicles. During the tests, the modified Insitu device recorded a significant reduction in the noise level of the device compared to the basic version of ScanEagle. Data on the recorded noise level is not disclosed. A less noisy machine will be able to fly closer to the positions of the enemy.
Modified drone ScanEagle received a hydrogen fuel cell developed by the American company Ballard Power Systems. An electric motor powered from it rotates a five-bladed propeller (in the basic version, a screw with two blades is used). Used screws with a large number of blades allowed to improve the flight performance of ScanEagle.
The basic version of ScanEalge is 1,7 meters in length and wingspan of 3,1 meters. The device with a maximum take-off weight of 22 kilograms is capable of carrying a payload of 3,4 kilograms. A drone can fly at speeds up to 148 kilometers per hour and be in the air for about 24 hours. ScanEagle is equipped with a high resolution camera and a thermal imager.
