Aurora Labs, an Australian manufacturing company, has achieved a significant milestone by successfully 3D printing a micro gas turbine. This turbine, designed for small propulsion systems or power plants in unmanned aerial vehicles, underwent rigorous development and testing. Utilizing 3D metal printing, the company expedited the prototyping process, producing an advanced product in under four months.
The turbine, compatible with natural gas and liquid fuels, surpassed laboratory prototype testing benchmarks, showcasing the capabilities of high-energy 3D metal printing. Now, the focus shifts to field testing, where the turbine will be integrated into remotely piloted airframes.
A3D, the company’s turbine engine division, aims to tap into the defense and aerospace markets with this cutting-edge technology. Compared to traditional manufacturing methods, the A3D engine offers advantages such as fewer complex parts, facilitating a faster and more reliable assembly process without compromising performance.
Efficiency and weight reduction are critical aspects of A3D’s testing strategy. By leveraging design optimization and selecting appropriate materials, the company achieved a 20 percent weight reduction compared to conventional engines in the same class. This lighter engine promises improved fuel efficiency for aircraft.
Aurora Labs stands ready to conduct production runs of the engine domestically, demonstrating its expertise in 3D printing technology. The successful development of this micro gas turbine underscores the potential of additive manufacturing in revolutionizing the aerospace and defense industries.
