Verification Testing of Aeronautical Constructions from Composite Laminated Materials in Designing Process

The importance of verification testing in the design process for composite laminated materials aeronautical constructions is discussed, and illustrated by means of two examples drawn from Aeronautical Department (Faculty of Mechanical Engineering, University of Belgrade) experience in the use of composites in a wide variety of structural applications. Laboratory verification testing is conducted at Aeronautical Department on all flight-critical dynamic components in order to determine structural adequacy. In this paper the analysis of behavior by verification testing for a main rotor blade for a light multipurpose helicopter propulsion system and a heavy transport helicopter tail rotor blade of composite laminated materials are given.
