[Mechanical Egineering]
In large gas turbine engines, the liquid fuel burned in the com-
bustor is typically pressure-atomized with a high-pressure fuel
pump. However as the dimensions of the engine are reduced,
the high-pressure fuel pump does not scale in size or weight
with the rest of the engine. As a consequence, in small gas tur-
bines of the type used in business jets, cruise missiles, un-
manned aerial vehicles, smart miniature munition systems and
various other small turbine engine applications, pressure atom-
ization becomes increasingly disadvantageous
