“…The notch was introduced near the root of the blade via die grinder. The release speed was predicted using a relationship between the notch depth and the release speed with the consideration of the notch concentration factor [VanderKlok et al (2016)]. In this work, spin pit testing was conducted with either one releasing blade and one balancing blade or one releasing blade and three short balancing blade segments.…”

Gas gun experiments can generate useful data for the design of jet engine containment shields at much lower costs. To replicate the damage modes similar to that on a containment shield in fanblade-out (FBO) testing, the gas gun experiment has to be carefully designed. This work focuses on the design of projectiles. Gas gun experiments were performed for flat composite panel targets with three different projectiles. FBO conditions were simulated using spin pit tests. The damage modes on the flat panels used in the gas gun tests were compared with damage modes on cylindrical composite containment shields used in spin pit tests. The results show that to generate similar damage modes, it is critical to ensure the shape of the projectile used in a gas gun test accounts for the deformation of the released blade during initial contact in the spin pit test.

“…Fan blade width could be smaller than the sensing coil and usually cannot be considered as an infinite plate target. When there is a need to increase the thrust or power in a harsh environment, the most common way is to change the blade material from aluminum alloy to titanium alloy, which has higher strength and corrosion/creep resistance [19,20]. The above applications all need a high resolution (e.g.…”

Planar inductive sensors are widely used for non-contact gap measurement. Usually, a change in size, shape, or material of the target requires a tedious recalibration of the measurement setup. This paper aims to present a new method to measure the gap from irregular and narrow targets using a planar inductive sensor without this tedious calibration process. The magnetic field distribution on this target was numerically studied, and the findings suggested that a simpler calibration would work by modeling the induced current in the target as a virtual planar coil. For this target, we found that the calibration curves corresponding to different materials can be obtained by adding a constant C to the base curve. To validate this approach, three planar coils of different sizes were tested with four metallic turbine blade-shaped targets. Results showed that the measured gaps matched well with the real gaps, with a maximum error of about 3.703%. The new approach can be applied to various applications including 3D printer build platform calibration, bandsaw blade deviation detection, and blade tip clearance monitoring.
