The invention relates to a thrust chamber device comprising a thrust chamber with a thrust space having a first portion, a second portion adjacent thereto, and a third portion adjacent to the second portion, the thrust space being delimited in all three portions by an outer nozzle wall having an outer thrust space surface, which outer thrust space surface tapers in the first and second portion toward the third portion, widens in the third portion away from the second portion, and has a narrowest point at the transition from the second portion to the third portion, the first portion being delimited by an inner nozzle wall with an inner thrust space surface, which tapers toward the second portion, an annular combustion chamber being formed between the inner thrust space surface and the outer thrust space surface and extending over the first portion.

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.
