Bearing assembly housing for an aircraft propulsion system

A gas turbine engine for an aircraft propulsion system, the gas turbine engine comprising:

• a compressor section;
• a turbine section;
• a rotational assembly including a bladed compressor rotor for the compressor section, a bladed turbine rotor for the turbine section, and a shaft interconnecting the bladed compressor rotor and the bladed turbine rotor, and the rotational assembly is rotatable about a rotational axis;
• and
• a bearing assembly including a bearing compartment housing and at least one bearing,
• the bearing compartment housing surrounds and forms a bearing compartment, the bearing compartment housing includes a housing body and at least one feed hole plug, the housing body extends circumferentially about the rotational axis, the housing body forms a first air flow path through the bearing compartment housing, the first air flow path connects the compressor section in fluid communication with the turbine section, the first air flow path includes a plurality of first air flow path feed holes, the plurality of first air flow path feed holes includes a plurality of first feed holes and a plurality of second feed holes, the plurality of first feed holes includes at least one obstructed feed hole and at least one unobstructed feed hole, each of the at least one feed hole plug is disposed within a respective one of the at least one obstructed feed hole to obstruct air flow through the respective one of the at least one obstructed feed hole along the first air flow path, and
• the at least one bearing is mounted to the housing body and disposed within the bearing compartment, and the at least one bearing is rotationally engaged with the rotational assembly.
