Images from Newark Air Museum by Karl Smith (JRGS 1946-51)
A Karl writes:
"The
picture shows, center from left, four Victor
models: the black and silver one, which is first prototype: the
all-white Mark 1 production version; the camouflage one with
rear air brakes deployed is a Mark 2 version; the camouflaged
one with 'Kuchmann Carrots' on the rear of the wing is also a
Mark 2.
"The 'Carrots' alter the airflow around part of the wing and, I
believe, reduce aerodynamic drag. To use their internal space,
they were filled with 'chaff' - strips of aluminium foil that
could be dispersed and reflect radar beams to give a confusing
return.
"The two white triangles to the extreme left are Vulcans showing
how the wing's leading edge was altered from the pure triangle
of the prototype."
