INTERMEDIATE CASING FOR A GAS TURBINE ENGINE
An intermediate casing includes an inner wall having an outer surface extending along a longitudinal axis, the outer surface having a first profile in a first plane, an outer wall having an inner surface a second profile in the first plane, and first through fourth arms each extending radially. The outer and inner surfaces and the first and second arms delimit a first cavity, the first cavity having a first area and the outer and inner surfaces being separated by a first distance. The outer and inner surfaces and the third and fourth arms delimit a second cavity, the second cavity having a second area and the outer and inner surfaces being separated by a second distance. The first and second profiles are such that the first area is substantially identical to the second area and the first distance is different from the second distance.
AIRCRAFT PROPULSION SYSTEM WITH VARIABLE AREA INLET
An assembly is provided for an aircraft propulsion system. This assembly includes a variable area inlet. The variable area inlet includes a moveable structure configured to move axially along an axial centerline between a first position and a second position. The variable area inlet is configured to open an airflow inlet passage into the aircraft propulsion system when the movable structure is in the first position. The variable area inlet is configured to close the airflow inlet passage when the movable structure is in the second position. The airflow inlet passage includes an inlet. The inlet extends axially along the axial centerline from a first end to a second end. A distance from the first end to the second end changes as the inlet extends laterally between a first side and a second side.

Gas turbine engine airfoil with large thickness properties
An airfoil for a gas turbine engine includes an airfoil with pressure and suction sides that are joined at leading and trailing edges. The airfoil extends a span from a support to an end in a radial direction. 0% span and 100% span positions respectively correspond to the airfoil at the support and at the end. The leading and trailing edges are spaced apart from one another an axial chord in an axial direction. A cross-section of the airfoil at a span location has a diameter tangent to the pressure and suction sides. The diameter corresponds to the largest circle fitting within the cross-section. A ratio of the diameter to the axial chord is at least 0.4 between 50% and 95% span location.
