Abstract

We made three different types of Pitot spheres with five pressure holes in order to research the characteristics of the Pitot tube. The results of our experiment are as follows : 1. For the hook-formed stem the effect on the characteristics by the stem is smaller than straight one, so that the former is better. 2. The Pitot sphere with α=40° is superior to that with α=30°. (α is the angle between the hole on the meridian and the equatorial plane).
