Thermal modelling of an abradability test

LATS (LERMPS Abradability Test Simulator) is an approach developed to estimate the temperatures evolutions during a rig test.

The target is to describe the thermal phenomena seen during real rub.

To-date, it is available as an Excel file including several specific functions.

LATS is a completely analytical approach considering a large number of revolutions comprising each 3 successive steps:
- Interaction between the blade and the coating at contact instant, unless a gap was generated previously between both parts.
- Heating by rubbing, assuming a very simple generation of a heat flux.
- Cooling in air, with the hypothesis of a medium at constant temperature existing around both parts.

The results are the variations of the temperatures in the system versus the number of rotor revolutions.
