Abstract (en)
[origin: EP2078822A1] The engine has a stator ring (15) for a high pressure turbine, and an external wall (20) for a transition channel between high pressure and low pressure stages. An enclosure (19) controls the stator ring. Another enclosure (21) distributes air for blowing the external wall. The enclosures are communicated by an orifice (21a1) controlled by a valve. The valve is opened, when the pressure in the enclosure (19) is greater than the pressure in the enclosure (21). The valve is closed, when the pressure in the enclosure (19) is less than the pressure in the enclosure (21).
