3.2.1 TAPS1 Through TAPS4 Technology
Development of the TAPS1 technology through single cup, sector, and full annular
rig testing followed by extensive demonstrator engine testing for performance,
emissions, and durability was described by Mongia ( 2003 ). A follow-on paper (viz.
Mongia 2011e ) provides insights on the engineering aspects of the various stages of
TAPS technology mixers starting from TAPS1 through the most recent TAPS4
features. We therefore provide only two
figures (viz. Figs. 25 and 26 ) to illustrate
their connection to Figs. 23 and 24 .
All the combustion air enters through the dome, Fig. 24 ; and therefore one can
use a more robust single-passage diffuser instead of multipassage diffusers required
for DAC and Dry Low Emissions (DLE) of aeroderivative power generation (Joshi
et al. 1998 ). Even though more than 80 % of combustor air enters through the
dome, it is still desirable to use domes with cowling as shown in Fig. 24 . The
hardware details of the pilot schematic of Fig. 23 are presented in Fig. 25 which
