Robotics Revolution: Pratt & Whitney’s Alfred Cuts Assembly Time in Half
Pratt & Whitney, a subsidiary of RTX, has made significant strides in automating its high-pressure compressor rotor assembly process at the Eagle Services Asia engine center in Singapore. The introduction of a robot named Alfred not only cuts assembly time for the GTF PW1100G-JM engine by an impressive 50%, but also allows human operators to focus on more intricate tasks. This effort is emblematic of the broader trend toward automation and operational excellence in the aerospace industry.
The Evolution of Alfred
The inception of Alfred was born out of necessity in 2021. A technician at the facility recognized the potential for improvement by speeding up the time-consuming 14-hour process of assembling the high-pressure compressor (HPC) module. Drawing on best practices from Pratt’s established production systems and integrating RTX’s Core operating system, the team at Eagle Services Asia aimed to automate the rotor assembly. The project rapidly evolved, transitioning from concept to operational automated cell within just two and a half years.
“From start to finish in two and a half years,” stated Gilbert Sim, the director of aftermarket operations at Pratt & Whitney. “We went from a concept in 2021 to design review in 2022 to a fully tested and operational automated cell in 2023.”
How Alfred Operates
Every day at 7:30 am, Alfred initiates its double shift, performing multiple meticulous tasks to prepare the rotors. These include placing them in an industrial oven, cooling them, and transferring them to a hydraulic stacking system. Alfred’s precise capabilities come with built-in safety features, eliminating risks associated with burns or injuries that human operators might face.
Sim likens Alfred’s assembly process to a child playing with Lego blocks: “The process of joining them up is just like a Lego process. It will stack them, press them, and ensure the proper heating to allow the eight-stage rotor assembly.”
The robot can complete this entire assembly in about seven hours, substantially reducing the operational load and allowing human staff to concentrate on tasks like rotor balancing, which require higher levels of expertise.
The Advantages of Automation
Pratt & Whitney’s venture into automation yields numerous benefits:
- Safer Operations: Reduced risk of workplace injuries.
- Enhanced Repeatability and Reliability: Minimizes rework and ensures quality.
- Efficiency: Significantly shorter assembly time and reduced waste.
- Space Optimization: Customized fixtures integrate software and hardware while minimizing footprint.
Future Innovations with Athena
As the company ventures further into automation, Alfred won’t be the only robotic assistant at Eagle Services Asia. Another robot, Athena, is slated to join the ranks in 2025. Pratt & Whitney sees Eagle Services Asia as a prototype, aiming to replicate its success across other facilities. By creating a standardized playbook for their Maintenance, Repair, and Overhaul (MRO) operations, the company is set to streamline processes and enhance productivity.
“We’re putting together a standardized playbook to share with other Pratt & Whitney MRO shops,” Sim explained. “This will help them cut down on implementation time and quickly learn from our experience, making their process smoother and faster.”
Pratt & Whitney’s commitment to automation does not stop at the assembly line. They have established the Singapore Technology Accelerator and the North America Technology Accelerator in Florida, which are being utilized as innovation hubs. These centers focus on driving idea generation and optimizing processes for other repetitive tasks associated with the GTF engine.
“I call it the ‘innovation playground,’” Sim said about the accelerators, emphasizing their role in fostering technological advancements within the organization.
Looking Ahead: The Impact of Automation on the Industry
The trend of incorporating advanced automation tools like Alfred and Athena is not merely a shift for Pratt & Whitney but reflects broader changes in the aerospace manufacturing landscape. As companies harness the power of Industry 4.0 solutions such as robotics, data analytics, and connectivity, they are setting the stage for a more efficient, safer, and sustainable future in aviation.
Automation in aerospace manufacturing represents an evolution that stands to benefit not just the companies involved but also the general public. More efficient production processes could lead to lower costs for consumers and improved services across the board.
