主权项 1. A gas turbine engine comprising an upstream zone and a downstream zone, wherein: the downstream zone is a fire-critical zone that requires a predetermined flow rate of ventilation fluid during use; a convergent-divergent nozzle is provided between the upstream zone and the downstream zone, and is arranged to convey fluid from the upstream zone to the downstream zone via a throat aperture; and the nozzle includes an assembly movable to vary the size of the throat aperture of the nozzle, thereby regulating the flow of ventilation fluid to the downstream zone.
