English term or phrase: WHEELSPACE TEMPERATURE
From experience I know this is a gas turbine variable that is monitored to make sure operating conditions are correct. If is is too high an alarm is generated(followed by a trip if the problem is not solved).

In this case the term occurs in a list of alarms: **wheelspace temperature high high**

A glossary I haven't compiled myself goes: "wheelspace = dégagement roue", do you think this is feasible?

Thanks in advance for any suggestion!

température de cavité rotor-stator
Explanation:
Sur le site anglais en référence, je trouve le texte suivant (illustré) :
"Current high performance gas turbine engines use rim seal purge air to maintain acceptable temperatures for the turbine disc. As the mainstream gas temperature increases, the rim seal cooling flow increases too. The practical approach of supplying the cooling air to the disc space is to bleed off a relevant amount of flow from a suitable compressor stage and discharge it into the cavity through the peripheral clearance rotor-stator gap. Thus continuous air flow "seals" the cavity against ingress of hot external flow."

Je trouve "cavité rotor-stator" dans la référence française.

De mes recherches je conclus qu'on peut mettre aussi "température interdisques stator-rotor"
