description |
Numerical simulations play a dominant role in
design of experiments to get first hand knowledge about the
aerodynamic behavior before the beginning of wind tunnel
testing. In the present work, the static longitudinal stability
characteristics of a single lobe winged-hybrid airship are
investigated with two different empennages. Based on the
previous computational and experimental work, numerical
simulations are carried out by generating unstructured
grids on scaled down geometry having ‘+ Type’ and a
‘inverted Y type’ empennage and by using SST turbulence
model for specified flow conditions. The shape of the hull is
a blunted spheroid-ellipsoid. The empennage arrangement
is the only geometric dissimilarity in these two cases. Results obtained are first validated with the available experimental data. Numerical results show that for such low fineness ratio
hull configurations, changing the tail configuration from ‘+
Type’ to ‘Inverted Y Type’ empennage has actually
decreased the static stability at low speed. These initial
numerical results will be useful for any future work related
to the design of experiments with ‘Inverted Y Type’
empennage. |
