Abstract : Charged particle collection rates are derived in terms of free stream conditions for a supersonic, blunt-nosed sounding rocket with an electrode at the stagnation point. The analysis applies at altitudes below about 70 km. It is shown that then the electric field at the electrode is sufficiently high to dominate the particle collection, as is possible in practice at the higher altitudes, one obtains an expression for the collection rate which applies to a wide class of rocket geometries and is largely independent of flow effect.
