Abstract : The pressure and density measured by instruments on high-speed flying objects (rockets and artificial earth satellites) are not equal to the pressure and density of the free atmosphere, but are linked to them by interrelationships that are sometimes quite complicated. Thus far, it has been assumed in all calculations that the pressure and density are constant throughout the volume of the instrument. However, the pressure and density in the instrument may vary from point to point. Consequently, the readings of the instrument may depend on the position of the sensor. In the paper, an attempt is made to take this circumstance into account and explore the conditions under which previous solutions are correct. (Author)
