Pratt & Whitney's Groundbreaking Leap in Additive Manufacturing
Pratt & Whitney, a subsidiary of RTX, showcases a significant advancement in additive manufacturing with the successful testing of its 3D printed TJ150 turbine wheel. This achievement is particularly noteworthy as the TJ150 marks one of the first rotating components produced using 3D printing technology. Designed for various autonomous systems and weapons, the compact turbojet engine provides 150 pounds of thrust, aligning with modern military and aerospace requirements. Chris Hugill, the executive director of Pratt & Whitney GATORWORKS, emphasizes that the testing confirms the engine's performance under operational speeds and temperatures while meeting projected lifespan criteria.
The redesign of the TJ150 utilizes a novel process known as unitization, which streamlines production by reducing the number of core module parts from over 50 to just a few. This not only accelerates production timelines but also significantly lowers manufacturing costs. Remarkably, Pratt & Whitney's engineers design and test the engine in just eight months, a testament to their innovative capabilities. This advancement signifies a critical shift from static engine parts to dynamic rotating hardware, underlining Pratt & Whitney's commitment to enhancing both delivery speed and part durability within the aerospace sector.
With a legacy that spans nearly a century, Pratt & Whitney continues to be a pivotal player in aircraft engine design and manufacturing, supporting over 90,000 engines in service worldwide. As the largest aerospace and defense organization globally, RTX employs over 185,000 individuals and generates sales exceeding $80 billion. The successful integration of advanced manufacturing techniques like 3D printing not only bolsters Pratt & Whitney's competitive edge but also reinforces RTX's strategic focus on innovation and technological advancement in the aerospace industry.
In other developments, Pratt & Whitney announces the expansion of its global GTF engine maintenance network, adding ITP Aero as the 21st facility. This collaboration enhances the maintenance, repair, and overhaul (MRO) services for engines powering the Airbus A220 and Embraer E-Jets E2 families, showcasing Pratt & Whitney's commitment to operational efficiency and fleet readiness.
Additionally, Raytheon, another RTX business unit, partners with the Norwegian government and Kongsberg Defence and Aerospace to develop the GhostEye® radar system. This advanced mobile sensor aims to enhance Norway's air and missile defense capabilities, further demonstrating RTX's strategic initiatives in the defense technology sector.
