SUMMARY:

Helicopters used in public safety operations go through several risk situations involving ballistic projectiles, one of the safest solutions is armor, offering maximum protection combined with technology.

The present work aims to project an armoring system for the AS-350 helicopter, using as material the polymer matrix composite reinforced with para-aramid fiber and glass fiber. Considering the airworthiness requirements and the restrictions determined by the manufacturer, an analytical method was used to study the effects of armor on the weight and balance of the aircraft. The project used the Aerospace Design Methodology in conducting the work.

To verify the efficiency of the ballistic composite, the experimental tests were carried out in an open outdoor environment where the composite was exposed to the impact of projectiles with a caliber of 5.56x45 mm. The performance of the material was analyzed by the results obtained in the tests and, this provided the determination of the protection reliability of the ballistic system. 

The armor design for the AS-350 proved to be safe to be installed on aircraft of this model, as a level III ballistic protection tool, without impairing its mobility.
