Description
The calculation of emissions from rockets requires a determination of time, location and the occurring species and their quantities. The University of Stuttgart is developing a tool to predict these for the launch and re-entry of rockets. The presentation will introduce the tool, which calculates the emissions of common propellants (LOX/LH2, LOX/CH4, LOX/RP-1, UDMH/NTO, Solid, Hybrid) for the launch and also estimates the afterburning and soot formation of engines. For re-entry, the formation of nitrogen oxides and particle distributions are also modeled in addition to the calculation of the distribution of atmospheric emissions due to the burning of the structure (e.g. aluminium and titanium alloys and CFRP).
The possibilities of the tool and its uncertainties will be illustrated using prominent examples. The data from the tool can be used to carry out climate and ozone simulations in order to record the atmospheric impact of space transportation systems.
