As soon as you say say you can't find something
on the internet, you find it. Whipple's original paper
is in the bibliography of this paper which summarizes
the dynamic effects of ourgassing jets on the orbit:

"On the outgassing and jet thrust of snowball comets," by
M. K. Wallis & A. K. MacPherson, in Astronomy and
Astrophysics, vol. 98, no. 1, May 1981, p. 45-49.
