Abstract
An aircraft includes a first gas turbine engine configured to ingest a first mass flow and a second gas turbine engine configured to exhaust a second mass flow. A first optically-based measurement system is configured to determine the first mass flow in response to performing a first imaging process on the first gas turbine engine. A second optically-based measurement system is configured to determine the second mass flows in response to performing a second imaging process on the second gas turbine engine.

An aircraft comprising:
- a first gas turbine engine configured to ingest a first mass flow;
- a second gas turbine engine configured to exhaust a second mass flow;
- and
- a first optically-based measurement system configured to determine the first mass flow in response to performing a first imaging process on the first gas turbine engine;
- and
- a second optically-based measurement system configured to determine the second mass flows in response to performing a second imaging process on the second gas turbine engine.
A method of monitoring a gas turbine engine during flight of an aircraft, the method comprising:
- operating a first a first gas turbine engine to ingest a first mass flow;
- operating a second gas turbine engine to exhaust a second mass flow;
- performing a first imaging process on the first gas turbine engine using a first optically-based measurement system to determine the first mass flow;
- and
- performing a second imaging process on the second gas turbine engine using a second optically-based measurement system configured to determine the second mass flow.
