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 distinguishing feature of the Aerotecnica AC-14 helicopter is its increased length compared to the Aerotecnica AC-12 model, which can accommodate up to 5 people on board, or else, it provides the ability to transport goods of small weight and size. The external design of the aircraft has also undergone a number of changes, which provided the helicopter with lower drag during flight, however, due to the increased dimensions of the aircraft, it did not have a positive effect on the maneuverability indicator.

 

 

The Aerotecnica AC-14 helicopter carried out its first experimental takeoff in 1957, while. due to the fact that the aircraft manufacturers from the company "Aerotecnica" previously had experience with testing aircraft similar to the current one, the Aerotecnica AC-14 helicopter successfully completed all tests, and almost immediately was sent to mass production. Nevertheless, the demand for the aircraft of this model was only in the Air Force of Spain, where, during the entire production 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.

 

 

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 Turbomeca Artouste IIB piston aircraft engine, which is capable of developing 400 hp of thrust. Due to the increased performance of the power plant, the flight speed of this aircraft has also increased significantly, which at maximum performance can be up to 180 km / h. Provided that additional fuel tanks are used, the helicopter can fly at distances up to 640 kilometers.
