Composite Propeller Blades have been developed and are now in production for the new generation of turbo-prop commuter aircraft.
The method of manufacture utilises special tooling and a resin injection process specifically developed to produce composites with good fibre volume fractions and correspondingly high structural properties.
Quality Control and NDT methods have been developed to ensure a high quality product, which involves the use of Ultrasonic, Radiographic and Vibrational Analysis.
Certification of the Composite Propeller has necessitated rigorous structural and environmental testing of the finished blades, involving specialised rigs and techniques. Material properties have also been evaluated for static fatigue capability, and the effect on these properties of long term exposure to various climatic conditions is underway.
The future of these blades is established and contracts for a number of aircraft projects are now being fulfilled in a new purpose built composites manufacturing facility.
