Summary

Tests at a Mach number of 1·60 show clear evidence of interference on the end tubes of a Pitot rake whose adjacent tubes touch. This effect is increased when the rake is made into a solid rectangular slab by the addition of fillets between the tubes. By making the gap between the tubes equal to one tube diameter the interference is almost eliminated.

The magnitude of the interference on the end tubes is considerably affected by the ratio of the Pitot orifice to the tube diameter; of the three values of this ratio tested the one close to unity (i.e. a sharp-edged Pitot) was found to have the least interference.
