Short summary

We developed a new tool to solve the challenge of installing high-strength bolts within the extremely compact spaces of aircraft engines. Our design employs a unique ratchet–pawl mechanism driven by a hydraulic cylinder to generate high torque. Testing confirmed that the tool can safely deliver an average torque of 136 N m within a mere 4 mm gap. This successful innovation enhances assembly safety and efficiency in confined areas and establishes a foundation for the intelligent tools.
