pintle vs. disc injector types

[Brad Sheridan]

Hi,
  Does anyone either have info, or know a good place to find info on the
characteristics of pintle type injectors vs. rotary(disc) injectors? I'm
curious about the linearity of flow rates in each, how they respond to
varying fuel pressures, how they compare in terms of fuel atomization, and
whatever other useful information is available on them.


Thanks,
Brad
