To break through limitations of traditional ways in measuring wind speed, to know seriate change of wind speed in wide space, and to offer guarantee of weather for action in space and etc, the way of measuring and calculating wind speed based on five hole Pitot carried by aeroplane is brought forward.

The speciality of pitot basing on the characteristic experiment of the environmental controlling system of a certain type of aircraft during testing flight is studied deeply,and the basic principle of pitot use is summarized.

Meanwhile,the method of calibrating wind velocity with Pitot is given.

Study on quasi-S type Pitot tube and its measurement characteristics;

Experiments and numerical simulations were conducted on various Pitot tubes in order to study the effect of the geometrical parameters on their measurement characteristics.

Used in working situations, extra errors are inevitably added to the measurement results of a Pitot tube due to deviations from its standard usage conditions.
