    摘要： The invention relates to a cold regulating valve (34) for a heat exchanger system of an aircraft propulsion system, where the cold regulating valve (34) comprises an open frame (40) which delimits an opening (45), two shutters (51,52) with an external convex shape slidely mounted on the open frame (40) between a closed position and an open position, a mechanism (60) linked to the shutters (51,52) and mobile between a first position and a second position, and wherein the mechanism (60) moves the shutters (51,52) from the closed position to the open position when it moves from the first position to the second position and vice versa, and an actuator acting on the mechanism to move it from the first position to the second position and vice versa.
    The specific embodiment of the cold regulating valve (34) generates a low drag when the shutters are in closed position.

    摘要： A system for modulating air flow in a gas turbine engine (100; 800) is provided. The system may include a seal wall (904; 952; 992) comprising an opening, a seal door (908; 970; 1000) configured to slideably engage the seal wall (904; 952; 992), and an actuator (505; 555 1-n ; 910) configured to move the seal door (908; 970; 1000) over the opening. In various embodiments, the system may include a surface forward of the seal door (908; 970; 1000). The seal door (908; 970; 1000) may be configured to seal a passage (899; 906; 954; 994) through the surface and the opening of the seal wall (904; 952; 992). A track (972; 1006) may be disposed under the seal door (908; 970; 1000). The track (972; 1006) may comprise cobalt. Rollers (1004) may be coupled to the seal door (908; 970; 1000) with the rollers (1004) on the track (972; 1006). The seal door (908; 970; 1000) may comprise a nickel-chromium alloy. A sync ring (902; 950; 998) may be coupled to the seal door (908; 970; 1000). The actuator (505; 555 1-n ; 910) may be coupled through the sync ring (902; 950; 998) to the seal door (908; 970; 1000).

    摘要： A gas turbine engine (20) includes a plurality of rotating components housed within a compressor section (24) and a turbine section (28). A tap (110) connects to the compressor section (24). A heat exchanger (112; 164; 292; 312) connects downstream of the tap (110). A cooling compressor (114; 162) connects downstream of the heat exchanger (112; 164; 292; 312), and the cooling compressor (114; 162) connects to deliver air to at least one of the rotating components. A core housing (152) has an outer peripheral surface (153) and a fan housing (154) defines an inner peripheral surface (156). At least one bifurcation duct (158, 160; 406, 408) extends between the outer peripheral surface (153) to the inner peripheral surface (156). The heat exchanger (112; 164; 292; 312) is disposed within the at least one bifurcation duct (158, 160; 406, 408).
