To increase these engines capacity a commonly used strategy is to reduce the clearance between the blades and the sealing system. However, this reduction causes non-desired contacts (rubbing) between the rotating and static components of the engine. This rubbing interaction has an adverse effect on the engine life (wear and thermal cracking) and efficiency. In this work, experimental tests were carried out to recreate the rub between an F110 steel fin and a Hastelloy X honeycomb seal. A conventional CNC machine controlled the sliding and penetration velocities, and the interaction forces and fin tip temperatures were measured during the rub. Results demonstrate the dependence that both, interaction forces and tip temperatures, have with sliding and penetration velocities. However, it is clear that this influence is more pronounced in relation to the sliding velocity. 1757-8981 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=166127 https://hdl.handle.net/20.500.11984/5453 Rubbing temperature measurement Honeycomb Thermography Labyrinth seal Experimental investigation of contact forces and temperatures in rubbing interactions of honeycomb interstate seals
