herky400M Posted November 1, 2014 Share Posted November 1, 2014 HELLO C-130 WORLD, a few years ago I asked a question concerning FUEL FLOW vs POWER SETTING .:cool: most of the our T56-A-15 engine show too much fuel flow in LSGI setting and in MAX REV compared with the charts in the TO 382C-2-3 section 9. in some cases there are also problems on the other settings, normal speed and flight idle. I don't know the Technical manuals other nations use, but it is the test were you have to compare : torque, fuel flow, RPM and TIT. Does any of you guy's, C-130 users, have similar problems ? how do you coop with this problem? is a straight FCU replacement? FF transmitters are calibrated at source of repair! thx 4 coop, herky400m @ BE Quote Link to comment Share on other sites More sharing options...
munirabbasi Posted November 2, 2014 Share Posted November 2, 2014 herky400M FF TX measuring FF before entering fuel manifold. there several adjustment as per procedure in TO 1c130-2-4 ie TD Null Normal adjustment and FCU adjustment so adjust the engine as parameter lay down 1c-130B-1 & ic-130B-2-4 Munir Abbasi Home ofhercules Pakistan Quote Link to comment Share on other sites More sharing options...
herky400M Posted November 3, 2014 Author Share Posted November 3, 2014 Munir, it's more complex than just adjust the td-valve, and where do I have to adjust the FCU? concering that the Start temperature is ok in NULL and AUTO. are the charts updated on what kind of fuel type we use, or does this not matter I've got figures from Spanish and French C-130's who shows simular "problems" there must be an exlpanation...... comon guys herky400M Quote Link to comment Share on other sites More sharing options...
ec130 Posted June 14, 2015 Share Posted June 14, 2015 how rich are your fuel controls? this can be accomplished by putting the engines at 900 TIT and going from auto to null. if it rises its rich if it lowers its lean. if its super rich you can adjust the bellow on the fuel control to lower the amount of fuel scheduled to that engine. You will have to accomplish an auto and null start to make sure its still in perameters, if not you can adjust the td valve for minor amounts of fuel.

pjvr99 Posted June 16, 2015 Share Posted June 16, 2015 Just saw this post, so here's my 2cents. A15 ff xmtr (big black metal block) tends to read higher than chartsindicate at lower throttle setting. D22A xmtr (small silver can) appears to be more accurate. My test cell runsboth types of engine. I can only surmise this is due to the way each transmitter works. A15 when engine is powered up, you can hear a clicking noise coming from the xmtr. On occasion when weexperienced fuel/acceleration problems , this clicking noise was erratic or even absent. The D22 xmtr, is a simplein-line turbine driving a pulse generator Quote Link to comment Share on other sites More sharing options...
