Aerotecnica AC-12

Aerotecnica AC-12 is a lightweight two-seat helicopter developed by the Spanish company Aerotecnica in 1956.

The project of the light aircraft model Aerotecnica AC-12 began to be created by Spanish aircraft manufacturers in the first half of the 50s of the last century. According to the design plans, the helicopter was to become an exclusively civilian aircraft, however, in the end, the helicopter was operated only for military purposes, which was due to the lack of interest in this helicopter model among private potential customers.

The Aerotecnica AC-12 helicopter has a simple but quite reliable design that provides the aircraft with high maneuverability, while the aircraft itself can be equipped with both an open and an enclosed cockpit, which to some extent allows increasing the scope of applicability of this aircraft.

The helicopter model Aerotecnica AC-12 made its first test flight in July 1954, however, due to the fact that the aircraft could not successfully complete the tests, a second prototype was soon created, which had higher stabilization performance during the flight, and it was thanks to such improvements that the aircraft finally completely passed the stage of its testing.

Despite the rather high prospects of the project, only the Spanish Air Force became interested in the helicopter Aerotecnica AC-12, which commissioned 10 aircraft of this model, which mainly performed the role of patrol airborne or airborne surveillance equipment.

Due to the ease of construction, the Aerotecnica AC-12 helicopter consumed little fuel, while its speed and maximum flight distance indicators are very acceptable and comparable to modern indicators of light aircraft of this class.

The cabin of the aircraft Aerotecnica AC-12 can accommodate up to two people – a pilot and a passenger, and due to the rather limited free space inside the aircraft of this model, transportation of any cargo on board the helicopter Aerotecnica AC-12 is not possible.

The power plant of the Aerotecnica AC-12 helicopter consists of one Lycoming O-360-B2A four-cylinder piston aircraft engine, which, having a capacity of 168 hp, allows the aircraft to accelerate to a maximum speed of 140 km / h, with the possibility of overcoming distances 450 kilometers (subject to the availability of additional fuel tanks).

For the entire time of release, the Spanish aircraft manufacturer Aerotecnica built 12 aircraft model Aerotecnica AC-12, including two prototypes and 10 production versions of aircraft.
