Work on the design of the pilot of the aircraft model Lockheed CL-475 started by American aircraft manufacturers of the corporation «Lockheed Corporation» in the middle of 50-ies of the last century, moreover, the project was exclusively a test character with an option to run these aircrafts serial production, and, as a for civilian and for military purposes, which in turn was supposed to provide a multi-purpose use of this aircraft.

At the stage of its development, the helicopter Lockheed CL-475 got a good aerodynamic shape, which allows the aircraft to be highly maneuverable, with specialists also considered the possibility of installation on the model more powerful and productive engine that would have allowed him among other things, to accelerate and to high velocities.

Its first test flight of the aircraft model Lockheed CL-475 has made in November 1959 years, while, with the exception of a fairly low airspeed, the helicopter, in general, fully met the expectations of aircraft manufacturers, and therefore, subsequently, on the basis of that aircraft began to appear other aircraft, including as a pilot nature, and launched into production.

One of the negative aspects of the Lockheed CL-475 aircraft was its small capacity - the aircraft manufacturers did not provide for more than two people on board, while the real cost of the aircraft turned out to be very high for consumers, and therefore it was decided not launch this model into production. For the same reason, which is the limited space on board the aircraft, the Lockheed CL-475 helicopter was unsuitable for carrying cargo on board, which also significantly limited its capabilities and functional application.

Due to the fact that the Lockheed CL-475 helicopter is only an experimental version of the aircraft, a very low-power piston-type power plant is used here, which includes one Lycoming VO-360-A1A aircraft engine, four working cylinders of which are capable of developing thrust of only 140 h.p. Using a similar power plant, the Lockheed CL-475 helicopter can accelerate to a maximum speed of 145 km / h, and cover distances of 120 kilometers.

All For aircraft manufacturers was built only one instance of the aircraft, then it is optimized for the test.
