COMPANY HISTORY

2011

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 retest and optimise the design thoroughly.

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 the functionality and aerodynamics of the blades. From thorough market research and extensive cost/benefit assessments, the size of the generator for the VAWT was found to be in the order of 10kW. Controller design and procurement for 10 kW Inverters were completed.

The resin Infusion method used in the manufacturing process until 2016 proved not as successful as expected. The number of production defects and variations in composite quality was too high. The search for more reliable material and associated technology started.
In July 2017, the work on a new turbine Product Definition Statement commenced. At the beginning of 2019, the PDS had been completed. New technology for all carbon-fibre components - The Blades, The Struts and the Generator cowling (Hub) - was implemented. The carbon-fibre moulds were produced, and they were ready to start manufacturing. LSM created a prototype with the use of the new technology.

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

It wasn't easy finding a new suitable carbon–fibre material.
A thorough market search continued from 2014 to 2017. During that period, Carbon Fibre manufacturing technology became more affordable. It was an incentive for us to intensify our search. Decreased prepreg purchase cost provided an opportunity to start the material testing process.

Completely new technology allowed us to produce a set of Test Coupons delivered to the University of NSW in Sydney. Mechanical Engineering LAB did the full scope of the static, dynamic and fatigue tests at UNSW under Dr Sonya Brown's supervision.

2018

University of NSW Mechanical Engineering LAB undertook to test our Carbon-Fibre coupons. The results were better than expected. Based on the report received, the decision was to implement the alternative manufacturing technology immediately. The new design allowed us to progress in our accelerating commercialisation process.

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

The turbine production moulds for the carbon-fibre parts were ready to be used to commence manufacturing.
The turbine parts made use of the new prepreg technology.
In the interim, we reviewed the original 10-kW rated Generator design because the power generated from the wind by the blades exceeded the 10-kW generator capacity. The University of New South Wales the Electrical Engineering Faculty, did the generator's new winding design process under Dr Li Dong's supervision. We commissioned the production of the new 15kW generator. Engineers simultaneously implemented compliance with IEC 61400-2 Standards in the process.

Construction of The turbine concrete foundation commenced for the tower installation near Canberra, ACT, Australia.

2021

It was a 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 can generate 50,000 kWh to 60,000 kWh per annum at an average wind speed of 7 m/s (depending on location) and will continue doing it for the next 25 years.
