| 主权项 | 1. A ventilation system for a gas turbine, comprising: at least one fan opening into an air extraction duct, the at least one fan configured to inject air into the air extraction duct; at least one device for varying a pressure drop in the air extraction duct, the at least one device being placed in a path of both an extraction air flow in the air extraction duct and the air injected by the at least one fan into the air extraction duct, the at least one device comprising a casing directly coupled to the air extraction duct, wherein the at least one fan is coupled directly to the casing; and a means for regulating an air flow rate in the air extraction duct, the at least one device adopting an equilibrium position under combined action of the extracted extraction air flow flowing along the air extraction duct and the air flow delivered by the at least one fan. | ||
