Canadair CL-227 Sentinel
The CL-227 Sentinel is a remote-controlled unmanned aerial vehicle (UAV) made by Canadair.
It displays a distinctively unusual bulbous hourglass profile. Lift is provided by a set of coaxial rotors emanating from the waist of the system. The engine air is exhausted upwards to minimize the infrared signature. The blades are made of composite materials as well as all the external skin and legs, in an attempt to reduce the radar signature. The main structure is made mostly of aluminium.
The prototype of the CL-227 was designed in 1977, and was made available to NATO allied clients in the early 1980s. In the late 1990s it was replaced by an updated version, the CL-327.
While designed purely for intelligence gathering, its strange and menacing physical appearance inspired Science Fiction writer Bruce Sterling to portray it as an assassination device in the novel Islands in the Net.

Famous quotes containing the word sentinel:
“It is a noble land that God has given us: a land that can feed and clothe the world; a land whose coastlines would enclose half the countries of Europe; a land set like a sentinel between the two imperial oceans of the globe.”
—Albert J. Beveridge (18621927)
