US Army patented a drone that can be launched from a grenade launcher

Employees of the US Army Research Laboratory Hao Kang and John Gerdes have patented the GLUAS drone, which is launched from a 40-mm grenade launcher.

The drone itself is packed inside a capsule case. After the shot, the body, having reached a predetermined height, opens and falls, releasing the apparatus inside.

Next, the on-board battery of the drone turns on, which provides power to the electric motor. He, in turn, drives the propeller in the rear of the drone into rotation. The lift is created by a parachute-type paraglider, and the short wings, when a given flight speed is reached, fold, after which they act as control surfaces.

Apparently, GLUAS will be controlled from the ground and transmit video to its operator in real time. In theory, its flight will take place at a range of up to 2 km and an altitude of up to 600 m. The duration of an autonomous flight is from 30 to 90 minutes.

While nothing is known about the presence of a working prototype, however, the GLUAS scheme can hardly be called original - folding drones launched from tube-shaped launchers are widely used in the US Navy.
