Introduction

In a significant advancement for the aerospace industry, Pratt & Whitney, a division of RTX (NYSE: RTX), has successfully completed testing on a 3D printed TJ150 turbine wheel. This pioneering endeavor marks a crucial development in additive manufacturing, significantly impacting how aircraft engines are designed and produced.

About the TJ150 Engine

The TJ150 engine is a compact turbojet designed to deliver high performance and reliability while generating up to 150 pounds of thrust. It is primarily utilized in various autonomous systems and military applications. Considering the growing demand for advanced aerospace technology, the successful implementation of 3D printing in the production of engine components is pivotal for meeting the stringent requirements of modern aviation.

Additive Manufacturing Benefits

The utilization of additive manufacturing allows Pratt & Whitney to expedite delivery times while enhancing the durability of parts. Chris Hugill, the executive director of Pratt & Whitney GATORWORKS, articulated the potential of this technology: "Today we're fielding and flying static engine parts. Rotating engine components, especially for expendable class applications, is the next step." These statements underscore the transition from static to dynamic applications, evidencing the transformative power of 3D printing technologies in aerospace.

Testing Process and Results

The recent series of tests confirmed that the turbine wheel can function at full operating speeds and temperatures while meeting expected life cycles. These achievements are vital as they pave the way toward introducing 3D printed components into aeronautical engines actively in service. The journey from initial concept to successful testing took less than a year, illustrating the efficiency of Pratt & Whitney’s innovative approach.

Innovations in Design

One of the key factors behind this success is the collaborative effort between technical and manufacturing teams at the Pratt & Whitney GATORWORKS and the RTX Technology Research Center. By adopting a strategy known as unitization, Pratt & Whitney reduced the part count for the core module from more than 50 to as low as six. This redesign significantly decreased both production time and costs, showcasing the company's commitment to innovation in manufacturing practices.

Future Implications

As Pratt & Whitney continues to push the boundaries of technology, the implications for the industry are profound. The ability to design, manufacture, and test engine parts within a span of eight months represents a shift toward greater flexibility and responsiveness in aerospace manufacturing. This rapid production capability may lead to more adaptive engineering processes and responsive supply chains, essential as the aviation market evolves.
