An aeroderivative gas turbine is a gas turbine adapted from an existing aircraft jet engine design, keeping the compact, lightweight construction of its aviation origin rather than the heavier frames, bearings and blading built into purpose-made industrial gas turbines. That heritage lets it start up, shut down and follow changes in electrical load faster than an industrial turbine, which makes it useful for power plants that need to respond quickly to shifts in grid demand. Widely used models include General Electric LM2500 and LM6000 and aeroderivative versions of engines from Pratt and Whitney and Rolls-Royce, and the turbines can also run in combined cycle configurations, using their exhaust to raise steam for a steam turbine or drive an absorption chiller, though they do not quite match a purpose-built industrial turbine efficiency in that role.

Facts
Technology TypeAircraft-derived industrial or marine gas turbine 1 Invented YearFirst documented aeroderivative application: the Metropolitan Vickers G1 (Gatric), based on the Metropolitan Vickers F.2 jet engine, completed sea trials as the first marine gas turbine in 1947. Later stationary-power aeroderivative designs follow from this marine and aviation lineage. Classification

Aeroderivative gas turbine, opening definition
Aeroderivative gas turbines are generally based on existing aircraft gas-turbine engines and are smaller and lighter than industrial gas turbines.
