R&D
CJR’s philosophy is to never rest on its laurels and to continually strive to remain at the forefront of propeller design and manufacturing technology. The industry continues to move forward particularly with advances in marine diesel technology and boat construction techniques.
To this end we have an ongoing ‘no compromise’ Research and Development programme constantly evaluating and advancing our propeller designs to improve performance, efficiency and smoothness of operation.
In addition, and equally as importantly, the R&D programme extends to our manufacturing practices where we continually adopt new techniques and invest in new machinery.
Propeller Design
Using a unique and highly complex software programme developed for CJR at the CTO in Gdansk incorporating Lifting Surface Theory and integrated with Computational Fluid Dynamics (CFD), we are able to test our designs in a virtual world that replicates real world conditions. This enables us to gather valuable data before validating the designs using models in laboratory tests and finally in full size sea trials.
The ability to electronically recreate real world conditions, and to predict performance with incredible accuracy, dramatically speeds up the design process. This 'appliance of science' does away with the traditional trial and error approach so typical of the industry.
