Patent number: 11480068Abstract: A system for use in servicing a turbomachine, the system including a first tubular body including an interior channel, and a second tubular body. The first and second tubular bodies are bendable between a neutral shape and a biased shape. The bodies are bent when in the neutral shape. The second tubular body includes a tip end, and the second tubular body is translatable within the interior channel. The first tubular body and the second tubular body are rotatable to selectively orient the tip end in multiple degrees of freedom. The system also includes a steering cable extending from the tip end, wherein the steering cable biases the tip end for selective orientation in additional degrees of freedom.Type: GrantFiled: October 15, 2019Date of Patent: October 25, 2022Assignee: General Electric CompanyInventors: Deepak Trivedi, Don Mark Lipkin, Rebinth Jose Robin, Shivakumar Basavanna, Andrew Crispin Graham
