(1) Install fuel manifold in test
setup similar to one shown in figure
6-10.
Test setup must be capable of
providing fluid at 190-210 psi (1.3-1.5
Mpa) with a flow rate of 20-22 pounds
per hour (9.1-10 kg/h).
Test fluid
shall conform to MIL-C-7024, type II,
and
shall be
kept at
76-84°F
(24.4-28.8°C).
(2) Start test setup and fully
open valve.
Adjust as necessary to
meet psi and flow rate requirements
above.
(3) Observe
spray patterns at
each atomizer.
The spray should be
finely divided droplets in the form of
a cone.
Compare spray patterns with
those shown in figure 6-11.
(4) If spray patterns do not
compare favorably with
satisfactory
patterns shown in figure 6-11, or if
fluid bubbles, runs, or spits from
