COMPANY HISTORY

2011

In order to prove a new technology, a half scale 3.5kW prototype was developed and tested on the rear pallet of a UTE! This UTE was driven along a private airfield hundreds of times at varying speeds to record aerodynamic and structural data. This unique test method allowed rapid design development and adjustment, to thoroughly retest and also optimise the design.

In 2011 design work on a 10kW generator has begun. It lasted till 2014. In 2014 the 10kW prototype was constructed. The subsequent tests using a ½ scale model mounted on a moving vehicle confirmed functionality and aerodynamics of the blades. From thorough market research and extensive cost/benefit assessments, the optimal size of the generator for the VAWT was found to be in the order of 10kW. Controller design and procurement of Inverters for 10 kW VAWT was completed.

Resin Infusion method used in the manufacturing process until 2016 proved to be not as successful as expected. The number of production defects and variation of composite quality were too high. The search for more reliable material and associated technology was undertaken.
In July 2017 the work on a new turbine Product Definition Statement commenced. With the beginning of 2019 this work had been completed. New technology for all carbon- fibre components - that is The Blades, The Struts and the Generator cowling (Hub) - was implemented. The carbon-fibre moulds were produced and ready to start manufacturing. First prototypes were made using the new technology.

Axowind contracted CCP (Cermak Peterka Petersen) to commence a Wind Tunnel study, to assure effectiveness of the aerofoil of the blades. Conducted Tunnel tests delivered necessary data enabling our engineers to verify current design and eventually correct it.

Finding new material suitable to our needs wasn’t easy.
Thorough market search continued from 2014 to 2017. During that period the Carbon Fibre manufacturing technology became more affordable. It was an incentive for us to intensify our search. Due to decreasing cost of prepreg, we found cost-effective prepreg and started material testing. It was commissioned to the University of NSW in Sydney. Full scope of the static and fatigue tests were done in UNSW by Mechanical Engineering LAB under Dr. Sonya Brown supervision.

2018

University of NSW Mechanical Engineering LAB undertook testing of our Carbon-Fibre coupons. The results were better than expected. Immediately the alternative manufacturing technology had been implemented. New design allowed to progress in our accelerating commercialisation process.

2020

New manufacturing technology for all carbon- fibre components such as turbine blades, struts and the generator cowling had been implemented.

The turbine moulds were produced ready to start manufacturing.
First prototypes were made with the use of the new prepreg technology.
In interim the original 10 kW rated Generator design had to be reviewed because the power generated from the wind by the blades exceeded the 10kW generator capacity. The process for the generator new winding design had been completed by the University of New South Wales at the Electrical Engineering Faculty under Dr Li Dong supervision. New 15kW generator was produced. Compliance with IEC 61400-2 Standards was implemented in the process.

Concrete foundation had been built for the turbine tower installation near Canberra ACT Australia.

2021

It was long and hard road for 15kW Axowind VAWT, but finally the turbine had been completed and erected for a successful trial test at Murrumbateman near Canberra ACT Australia.

Axowind 15kW VAWT turbine is capable of generating 50,000 kWh to 60,000 kWh per annum at average wind speed of 7 m/s (depending on location) and will continue doing it for the next 25 year.
