Sailors attached to the USS Fitzgerald (DDG 62) recently received training at Naval Surface Warfare Center Philadelphia Division (NSWCPD) to perform maintenance to the ship’s propulsion system.
While attending the training at NSWCPD, Sailors learned how to use a borescope. A borescope is an optical device used for visual inspections where the area to be inspected is unreachable or difficult to view without disassembly.
“The Sailors are looking for any significant damage or deformities to a blade within the gas turbine engine,” said Scott Brown, an engineering technician in NSWCPD’s Gas Turbine Engine Life Cycle Support. “They are also identifying the correct location of blades, type of damage inside the engine and proper terminology to provide a detailed report for further analysis.”
According to Brown, a borescope is the primary means of discovering potential and or existing internal damage to the gas turbine engine, and that use of the borescope could be considered a form of preventative maintenance.
The borescope allows Sailors to look inside a gas turbine engine for any damage or deformities. Issues that are detected and repaired early can save the engine from being replaced saving the Navy time, money and resources.
“If damage can be identified in its early stages, repairs may be accomplished to that isolated damage,” Brown said. “If left undetected, that damage can become catastrophic. This catastrophic damage could result in replacement of a complete gas turbine engine. Which would cost the Navy time and money for work force, tooling, pier support and a ready for installation gas turbine.”
“While here at NSWCPD Sailors get to work on a gas turbine in a training environment,” Brown said. “There is plenty of time for detailed questions to be asked and answered. This training also acts as a team building exercise. The more experienced Sailors get to share knowledge with Sailors new to the Navy and establish a good and professional rapport.”
NSWCPD employs approximately 2,700 civilian engineers, scientists, technicians, and support personnel doing research and development, test and evaluation, acquisition support, and in-service and logistics engineering for Navy ships. NSWCPD is also the lead organization providing cybersecurity for all ship systems.
