- In this article a review of rotor,hub constructions were presented. Discussed rotor’s hub ismade of composite or aluminum alloys materials. Two types of rotor hub were presented (four-blades and two-blades teetering rotor hub), each of them are dedicated to gyroplanes. Typical gyroplane main rotors are characterized by simple design, especially in case of rotors forlight gyroplanes. In the following part of the article thetype of strength tests required by certification process were shown. The test programs based on legal aspects of admission to the flight tests taking into account legislation such as CS 27 (Subpart C – Strength Requirements), CAP 643 British Civil Airworthiness requirements Section T Light gyroplanes, ASTM F2972. Furthermore, this articlediscusses strength tests of gyroplane rotor hub such as measured parameters, methodology of measurement, types of sensors, course of test, test stands, and limit loads. The loads during “pull-up from level flight” manoeuvreare limit loads during tests. Required additional processes, like averification the same parameters by two types of method were shown i.e.deformation of structure were tested by strain gauges and reverse engineering.Strength tests had to be made before flight test, based on results of them aircrafts are flight authorized. In conclusion,the results of tests were presented and fulfilment of legal assumptions and requirements were shown.
