GE Aerospace has introduced the Sensiworm, a bio-inspired soft robot designed to enhance inspection processes within jet engines.
Unlike conventional inspection tools like video borescopes, which face limitations in coverage due to factors like gravity, Sensiworm offers a dynamic solution.
This compliant robot could serve as additional sensory and visual aids for aerospace service operators. It presents the potential for unfettered access during inspections, eliminating the need for engine disassembly.
Sensiworm Robot: Game-Changer for On-Wing Inspections
Deepak Trivedi, Principal Robotics Engineer at GE Aerospace Research, envisions the Sensiworm robot as a game-changer for on-wing inspections. Its soft, pliable design enables it to navigate every nook and cranny of a jet engine, providing real-time video and data on component conditions.
Beyond visual inspections, Sensiworm has the capability to measure the thickness of thermal barrier coatings, which is crucial for parts protection against heat.
"With their soft, compliant design, they could inspect every inch of jet engine transmitting live video and real-time data about the condition of parts that operators typically check. Sensiworm can even measure the thickness of thermal barrier coatings on parts that are applied to protect the parts from heat," Trivedi said in a statement.
Trivedi also expressed a vision beyond inspection, foreseeing the possibility for these robots to execute repairs upon identifying defects.
This project receives financial backing from SEMI Flex Tech, an industry-driven public/private partnership focused on advancing innovative hybrid electronics like Sensiworm. The US Army Research Lab funds this initiative.
The collaboration extends to Binghamton University and UES, Inc., both prominent organizations in the field of aerospace and electronics research.
"Our partnership with SEMI Flex Tech, Binghamton University, and UES has provided an incredible platform to accelerate the development of our Sensiworm robot," Trivedi said.
"The programs they support are critically important in helping private industry deploy new technologies from the lab into their business operations. We still have more developments ahead with Sensiworm. But the early results from our demonstrations show that we indeed have real 'skin in the game' when it comes to deploying future robotic solutions in aircraft engine services," he added.
Robot Resembling an Inchworm
Furthermore, Trivedi emphasized that platforms like Sensiworm are pivotal for conducting robust on-wing inspections, potentially reducing unnecessary removals and downtime.
This advancement could lead to faster turnaround times, maintaining engines at peak operational efficiency. Sensiworm, resembling an inchworm, is designed as a highly adaptable soft robot equipped with onboard power, computing, and pressure resources.
The company noted that it has demonstrated exceptional mobility around the intricate features of jet engine components, detecting cracks and corrosion.
Sensiworm has also showcased its proficiency in accurately measuring the thickness of thermal barrier coatings, which is vital for ensuring parts maintain their required dimensions.
