Abstract

A dynamic pressure probe for a sensor device can determine the relative speed of an object and a medium surrounding that object, in particular for gathering flight data on a flying object. The dynamic pressure probe includes an outer body with a wall in which an inflow opening is formed and which encloses an inner space, as well as an inner body which is arranged at least partially in the inner space and which encloses a measuring space as a constituent part of the inner space. Medium is able to flow through the inflow opening and is able to be dammed in the measuring space. The inner body is able to be acted upon with a protective fluid, in particular a gas, on a side remote from the measuring space and includes passages through which protective fluid is able to flow into the measuring space.
