Abstract
The invention relates to a method for measuring the flow rate of cooling air in a cooling air circuit () of a casing () of a high-pressure turbine () of a turbomachine (). The invention is characterized in that sensors () are used to measure a total pressure at the fan inlet, a static pressure at the outlet of the high-pressure compressor (), a rotational speed of the low-pressure shaft (), a rotational speed of the high-pressure shaft () and a degree of valve opening of the cooling air circuit (), a calculation unit is used to calculate the flow rate of cooling air on the basis of at least the measurement of these.
