EPRI (Electric Power Research Institute) reports that 7FA gas turbines have a rotor life of about 144,000 hours, or 5,000 starts. The primary life-limiting factor is high cycle fatigue cracks ...

The study of aerodynamic performance in compressor blades is critical for optimising the efficiency and reliability of modern turbomachinery. Recent work has focused on the dual challenges of ...

Back in the early 2000s, some controversy emerged about the practice of spraying large amounts of fog directly into the compressor. Some claimed that this led to blade erosion, pitting, and scaling.

Iberia Maintenance is developing an automated robotic workshop that will accomplish each step of a compressor blade repair process in a closed, predictable environment. The automated repair process, ...

LONDON – Aero-engine manufacturer, Rolls-Royce says it has certified a redesigned intermediate pressure (IP) compressor blade for Package C variants of the Trent 1000 engine that powers the Boeing 787 ...

Mechanical Dynamics & Analysis (MD&A) repaired a Frame 5 gas turbine rotor. MD&A replaced 1st and 2nd stage buckets, repaired the seal area on the row 1 turbine wheel, performed compressor blade ...

The automotive industry is undergoing a transformative shift toward sustainable propulsion systems to meet stringent environmental regulations, such as the European Union’s push for near-zero-emission ...

During the 1990’s, some power plants experimented with fog-based power augmentation by overspraying fog into the compressor – known as wet compression. The results were impressive. They reported a ...

“When there is a system issue that leads to short cycling of a compressor, the case temperature will increase, which will normally be noticed by the equipment owner.” - Joe Marchese Continuous and ...
