In the modern aviation context, is the word "supercharger" generally assumed to mean a gear-driven system rather than an exhaust-driven system?
At one time the word "supercharger" often was used to encompass both turbosuperchargers (aka turbochargers) which were exhaust-driven, and gear-driven superchargers. But I have seen the word "supercharger" used to specifically mean a gear-driven system as distinct from an exhaust-driven system. Would this usage be generally considered unambigous and good practice in the modern aviation context? Or at least, very common practice in the modern aviation context?
(Include belt-driven along with gear-driven, if such a thing even exists in aviation engines. The question is about exhaust-driven versus mechanically-driven devices, and how these two different sorts of devices map out against the various terminology in current aviation use.)
A supplemental question might be: "Has the word 'turbosupercharger' completely disappeared from modern aviation terminology?"
