You can test this :

\multido{\rv=0+20}{18}{%
\psSolid[object=vecteur,
definition={[.1 .5]},
linecolor=red,
args= \rv\space Sin \rv\space 2 mul Cos neg
\rv\space Sin \rv\space 2 mul Sin neg
\rv\space Cos
](\rv\space 2 mul Cos 2 mul, \rv\space 2 mul Sin 2 mul, 0)
}

where "definition={[r h]}" mean
   radius=r
   height=h
for the arrowhead
