  The accuracy and resource consumption of the four different turbulence models
based on the eddy viscosity assumption, namely, $k-\varepsilon$, two $k-\omega$
and Spallart-Allmaram models, in modeling airships are investigated. The test
airship shape is a conventional shape. Three different angles of attack are
considered. The results are checked against the wind tunnel experimental data.
The resource consumption study is based on the benchmark of 1500 iterations.
Based on all data obtained it is evident that Spallart-Allmaras model is the
most optimal one in the majority of cases.
