RTX's Innovations in 3D Printing Transform Engine Development
Revolutionizing Engine Manufacturing with 3D Printing
Additive manufacturing is paving the way for increased delivery speed and enhanced durability of parts in the aerospace industry. In a notable development, Pratt & Whitney, a key business under RTX (NYSE: RTX), has made remarkable advancements through testing its innovative 3D printed TJ150 turbine wheel. This significant achievement showcases the potential of 3D printing in revolutionizing traditional manufacturing processes.
The TJ150 engine is recognized for its compact and high-performance features, which enable rapid production without compromising reliability. Generating 150-pounds of thrust, this engine is designed for diverse applications including autonomous systems and various weaponry.
Key Insights from the Testing Process
Chris Hugill, the executive director of Pratt & Whitney GATORWORKS, emphasized the importance of this testing phase. "Today we can utilize static engine parts in the field, but the true challenge lies in successfully implementing rotating components for expendable applications. Our recent tests illustrate that we are achieving full operational capabilities alongside expected lifespan metrics. This technology is significantly transforming our design and delivery processes," he stated.
The journey of the TJ150's redesign was driven by Pratt & Whitney GATORWORKS, where engineers collaborated closely with the RTX Technology Research Center. A process known as unitization allowed the team to minimize the core module components from over 50 to a mere handful. This dramatic reduction not only shortened production timelines but also slashed associated costs. The team leveraged their in-house expertise to design and finalize the engine within eight months, with this testing marking a critical progression from static to rotating hardware.
