GAS TURBINE WITH EXTENDED TURBINE BLADE STREAM ADHESION

摘要

A gas turbine may include turbine blades configured to improve stream adhesion by selectively attracting or reducing repulsion of charged particles carried by a combustion gas stream. According to an embodiment, a gas turbine may include a combustor configured to output a combustion gas stream, the combustion gas stream being controlled or driven to at least intermittently or periodically include charged particles having a first sign. For example the first sign may be positive during at least an instant. The gas turbine also includes at least one turbine configured to receive the combustion gas stream (carrying the charged particles at least intermittently or periodically). The turbine includes at least one turbine stage having turbine blades. Each turbine blade includes a repelling surface configured to be at least intermittently or periodically held or driven to a repelling voltage having a polarity the same as the charged particles having the first sign.
