As a basic framework, design engineers using Model Aerotecnica AC-12Which was able to successfully prove itself in the Air Force of Spain, however, could not be as effective as possible in their operational plan.

The main feature of the helicopter Aerotecnica AC-14 is its extended length, compared with the model Aerotecnica AC-12, that allows you to put on the board before 5 people, or just allows the transportation of loads a small weight and size. A number of changes undergone, and also the exterior design of the aircraft, the helicopter ensured less drag in flight, however, because of the increased size of the aircraft, does not positively affected the index maneuverability.



His first experimental helicopter rise into the air Aerotecnica AC-14 1957 carried out in the year, at the same time. because aircraft manufacturers of the company «Aerotecnica» had already had experience with the testing of aircraft like the current, helicopter Aerotecnica AC-14 has successfully completed all the tests, and almost immediately was sent into production. Nevertheless, the demand for aircraft in the model had only the Air Force of Spain, where, for the entire release cycle, 10 aircraft of this model were delivered.

As before, the helicopter Aerotecnica AC-14 could have either open or closed cabin, however, the most popular use layout with a closed cabin, which was due mainly to the fact that the helicopter speed 180 km \ h., The pilot and passengers felt uncomfortable with, especially if it was a question of extended-range flight.

Helicopter Aerotecnica AC-14 equipped with a piston aircraft engine brand Turbomeca Artouste IIB, which is able to develop traction in 400 hp Due to the increased performance of the power plant, has greatly increased the speed and flight of the aircraft, which is at the highest rates can be up to 180 km \ h. Assuming the use of additional fuel tanks, helicopter flights can produce at distances of up to 640 kilometers.
