Description:
This paper contains the results of an experimental investigation
into the effect of a jet issuing from two afterbodies (one a right
cylinder and the second conical) at incidence to a uniform subsonic
flow. The tests were performed at a Reynolds Number of 0.3 x 10^6
based on body diameter and maximum turnel velocity.
The presence of the jet issuing from an afterbody at incidence
significantly increases the magnitude of the normal force, axial force
and pitching moment arising from the external forces but not including
the direct reaction of the jet. On the bluff cylindrical afterbody
the effect of the jet is comparable in magnitude to the effect of
incidence. However the effect of the jet on the conical afterbody is
secondary to the effect of incidence.
