Pratt-Read LBE-1 - US military unmanned aerial vehicle developed in 1943, the company «Pratt-Read».
Design of unmanned aircraft model Pratt-Read LBE-1 was deployed in the early 40-ies of the last century, and, the main initiator of the beginning of the development in this direction were initiated by US naval forces, who were in need of devices capable of inflicting enemy ships massive damage and destroy enemy fortifications are within the coastline.
UAV Pratt-Read LBE-1 is a glider equipped as bomb load charges, detonating or in contact with the drone in the intended target, or when you reset the bomb, without causing immediate damage to air tools. Despite the prospects of the project, run it in serial production failed due to technical imperfection.
The first test flight of an unmanned aerial vehicle Pratt-Read LBE-1 has made in 1943 year, however, despite the fact that the tests were carried out successfully, the project has not received proper approval as control this drone could only be in the area of device visibility, in particular , the effective radius of action of the UAV is only about 25-30 kilometers, while the actual device can cover a distance of over distances in 150-200 kilometers.
UAV Pratt-Read LBE-1 can also be controlled and pilot, however, actually, if necessary, the device is positioned as unmanned aerial means.
On arms of the drone can be either one-kilogram bomb 1810 or 910 same two-kilogram bomb.
Powerplant UAV Pratt-Read LBE-1 represented by one piston engine, providing the ability to accelerate drone forth the maximum airspeed in 230 km \ h., Which is quite acceptable, and, in a dive, this figure could reach 490 km \ h.
