Abstract
The XFV-12A is a high performance, VTOL, fighter/attack
aircraft which incorporates ejectors in the wings and canards
for thrust augmentation. During transition from VTOL to
normal flight, the interaction between downflow of the lifting
jets and relative flow from forward flight generates
vortices distinct from airfoil circulation. These vortices
are associated with the bending of the lifting jets resulting
in induced velocities at the aircraft; the magnitude and
influence of the vortices are unknown. The object of this
thesis was to prepare a suitable one-tenth scale semi-span
model of the XFV-12A for a smoke tunnel flow visualization
study to explore vortex development. Performance testing
was conducted on the canard augmentor, which resulted in
a gross augmentation ratio of 1.34 and mass flow ratio of
6.84.
