(n.) A set of limits for the performance capabilities of some type of machine, originally used to refer to aircraft. Now also used metaphorically to refer to capabilities of any system in general, including human organizations, esp. in the phrase push the envelope. It is used to refer to the maximum performance available at the current state of the technology, and therefore refers to a class of machines in general, not a specific machine.
