How much farther could you skip a rock on Titan?
This is clearly a question I should devote some effort towards considering, not least
since I have instrumented skipping stones with accelerometers etc.... as described in
my book 'Spinning Flight: Dynamics of Frisbees, Boomerangs, Samaras and Skipping
Although there have been some neat analyses of the skipping process, the combined
aerodynamic-gyrodynamic-hydrodynamic problem of modeling an end-to-end stone
skip trajectory has not been satisfactorily modeled (e.g. as my book qualitatively notes,
the pitch-up aerodynamic moment and the pitch-down moment usually generated by
water impact at a positive angle of attack tend to make the spinning stone roll in
Might be the viscosity and surface tension of Titan liquids affect the process in ways
that can only really be studied experimentally..
