Abstract
Techniques for determining temperature and velocity in a space inside a gas turbine engine () include mounting acoustic sensors () in the engine. The sensors are mounted to detect acoustic signals in a space () of fluid flow without extending into the space. A first sensor () is displaced a first distance () from a different second sensor () in a first direction parallel to fluid flow through the space. First and second signals are detected at the first and second sensors, respectively. A travel time difference between the first and the second sensors is determined by control system () module () based on the first and second signals. Velocity of fluid flow in the space is determined by the module based on the travel time difference. Temperature of fluid flow in the space is determined by the module based on either the first or the second signals or both.
