Pratt & Whitney has accomplished a sequence of checks on its 3D printed TJ150 turbine wheel. The corporate, an RTX enterprise, studies the checks had been profitable and characterize an advance of their additive manufacturing capabilities. The turbine wheel is notable as one of many first rotating components to be manufactured utilizing 3D printing expertise.


The TJ150 is a compact turbojet engine producing 150 kilos of thrust. It’s designed to be used in autonomous techniques and weapons purposes. The engine may be manufactured rapidly and has established reliability metrics, based on the corporate.
“Immediately we’re fielding and flying static engine components. Rotating engine elements, particularly for expendable class purposes, is the following step,” mentioned Chris Hugill, government director of Pratt & Whitney GATORWORKS. “Our testing confirms we’re on observe with the engine acting at full working speeds and temperatures and assembly anticipated life length. This expertise is reworking how we design, develop and ship capabilities sooner.”
The redesign of the TJ150 was led by Pratt & Whitney GATORWORKS in collaboration with the RTX Know-how Analysis Middle. Engineers used a course of referred to as unitization to scale back the core module half depend from over 50 elements to just some. This discount decreased each manufacturing time and value. The engine was designed and examined inside an eight-month timeframe utilizing in-house capabilities.
This newest spherical of testing represents a shift from utilizing additive manufacturing for static buildings to implementing it for rotating {hardware}. The event might impression future manufacturing approaches for aerospace elements, significantly in navy and protection purposes.
