Actuatable airflow splitter for an aircraft powerplant

An assembly for an aircraft propulsion system, comprising:

• an inner wall structure extending axially along a first axis to an inner wall upstream end, the inner wall structure extending circumferentially about the first axis, and the inner wall structure forming an outer peripheral boundary of an inner flowpath;
• an outer wall structure extending axially along the first axis to an outer wall upstream end, the outer wall structure extending circumferentially about the inner wall structure and the first axis, and the outer wall structure forming an inner peripheral boundary of an outer flowpath;
• a splitter extending axially along the first axis to a leading edge, an inner section of the splitter connected to the inner wall structure at the inner wall upstream end, an outer section of the splitter connected to the outer wall structure at the outer wall upstream end and meeting the inner section of the splitter at the leading edge, and the splitter comprising a deformable material;
• an actuation system mechanically coupled to the splitter and configured to move the leading edge radially relative to the first axis;
• wherein the actuation system comprises a rocker arm, and the rocker arm includes a base, a first arm and a second arm;
• wherein the base is between the first arm and the second arm and is configured to pivot about a rocker axis;
• and
• wherein the first arm projects longitudinally out from the base towards the leading edge, and the first arm is operatively coupled to the splitter.

An assembly for an aircraft propulsion system, comprising:

• an inner wall structure extending axially along a first axis to an inner wall upstream end, the inner wall structure extending circumferentially around the first axis, and the inner wall structure forming an outer peripheral boundary of an inner flowpath;
• an outer wall structure extending axially along the first axis to an outer wall upstream end, the outer wall structure extending circumferentially around the inner wall structure, and the outer wall structure forming an inner peripheral boundary of an outer flowpath;
• a splitter connected to the inner wall structure at the inner wall upstream end, the splitter connected to the outer wall structure at the outer wall upstream end, the splitter projecting axially along the first axis to a leading edge, and the splitter comprising a deformable material;
• and
• an actuation system comprising a rocker arm operatively coupled to the splitter, the actuation system configured to move the leading edge radially relative to the first axis by pivoting the rocker arm about a rocker axis.
