Ion sensor signal fluctuations during spacecraft jet engine operation
Abstract
Flight data of the Cosmos-398, Soyuz, Progress, and Salyut spacecraft are presented to illustrate the effect of jet engine operation on the ion sensor signals. It is shown that the amplitude, duration, and phase of ion sensor fluctuations observed during the flights are determined by the engine thrust, the amount of the effluent gas, and the gas jet direction. It is also shown that the gas jets of jet engines affect the ion sensor signal irrespective of the type of the working medium used (compressed air, hydrogen peroxide, or bipropellant). Changes in the amplitude and phase of the fluctuations are correlated with changes in the components of the earth's magnetic field in the orbital coordinate system.
