Gastops’ fan blade health monitoring system detects early damage to the first stage blades based upon tip timing detection technology – in-flight, in real-time.
The fan and compressor blades of the most advanced aviation gas turbine engines are highly sophisticated structures that rotate at high speeds under significant stress and environmental conditions. Initial damage to the first stage fan blades often appears as cracks at the blade root, which if undetected, will progress to blade separation.
The most advanced engine flying today, Pratt & Whitney F135 engine, is the first production engine to incorporate a fan blade health monitoring system using sensors supplied by Gastops. The sensors are statically mounted in the fan casing; the relative position of each fan blade tip is detected, and by tracking the timing, damage to individual blades is determined in-flight, in real-time. These Gastops sensors are an important contribution to F135 engine’s state-of-the-art gas turbine condition monitoring technology.
