Aerotecnica AC-14 - Spanish five-seat multi-purpose military helicopter designed «Aerotecnica» company in 1957 year.

Design helicopter Aerotecnica AC-14 Spanish aircraft manufacturers began to 1955 year. 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 distinctive feature of the Aerotecnica AC-14 helicopter is its increased length compared with the Aerotecnica AC-12 model, which allows people to be placed on board up to 5, or it also provides the ability to transport cargo of small mass and size. A number of changes have also undergone the exterior design of the aircraft, which provided the helicopter with less drag when flying, however, due to the increased dimensions of the aircraft, which had no positive effect on the maneuverability index.

The Aerotecnica AC-14 helicopter made its first experimental ascent into the air in the year of the 1957. due to the fact that aircraft manufacturers from the company “Aerotecnica” had previously had experience with testing aircraft similar to the current one, the Aerotecnica AC-14 helicopter successfully completed all tests, and was almost immediately sent into serial production. However, demand for aircraft of this model was available only in the Spanish Air Force, where, for the entire production cycle, 10 aircraft of this model were supplied.

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.

On board the aircraft Aerotecnica AC-14 can accommodate up to five people, including one pilot and four passengers, which greatly increased the functionality of the aircraft of this model compared to the model Aerotecnica AC-12, on board which could accommodate only two persons . Moreover, due to the expansion of space inside the cab, the helicopter Aerotecnica AC-14 can also be used for transporting small loads, provided that the maximum takeoff weight of the aircraft will not be exceeded in 1350 kilogram.

The Aerotecnica AC-14 helicopter is equipped with one piston aircraft engine of the Turbomeca Artouste IIB brand, which is capable of developing thrust in 400 hp. Due to the increased performance of the power plant, the flight speed of this aircraft has significantly increased, which at maximum performance can be up to 180 km / h. Subject to the use of additional fuel tanks, the helicopter can make flights at distances up to 640 kilometers.
