M.. -17-1B. Flight manual
(g) Steady illumination of the OIL PRESS NORMAL (MBJl. MACJl.
HOPMA), NORMAL SPEED (060POTbl HOPMA) and STARTER
ON (CTAPTEP PA60TAET) annunciators.
(h) Disengagement of the pneumatic starter at a gas generator rotor
speed of 60 to 65%. If the pneumatic starter is not disengaged, shut
down the APU.
If some abnormal readings of the instruments are detected or the
ground observer issues come warning command it is necessary to
report to the Captain and shut down the engine by closing the fuel
shutoff valve and depressing the START DISCONT
(nPEKPAIl.\EHlI1E 3AnYCKA) button.
(6) After the engine gains the idling speed the Flight Engineer should check
its operational parameters which should remain within the following limits:
(a) The gas generator rotor speed - in accordance with the graph of
Fig. 3.3.
(b) The turbineinlettemperature - in accordance with the graph of Fig. 3.3.
(c) The engine oil pressure" 2 kgf/cm
2
,
minimum.
(d) The main gearbox oil pressure - 0.5 kgf/cm
2
,
minimum,
(e) The fuel pressure - 18 to 22 kgf/cm
2
.
(7) Set the LEFT - RIGHT (JlEB - nPAB) selector switch to the position re-
qulred to start the second engine proceeding in a similar way.
After two engines are started and have gained the idling speed the main
rotor speed should be within the limits of 55 to 70%.
(8) After starting the TB3-117BM engines shut down the AlI1-9B APU having
previously cooled it down at idle for 0.5 to 1.0 min.
Note: If the engines are started only from the aircraft storage batteries do
not shut down the APU until warming up run of the engines is com-
pleted and the engines are accelerated to a power above idle (up to
a main rotor speed above 80%).
To power the necessary loads with the engines running at idle it is
necessary to switch on the CTr-3 APU generator by setting the
STBY GEN (PE3EPBH. rEHEPAT.) and EQUIPM TEST
(npOBEPKA 060PY,Q) switches to ON (BKJl);
(9) With the TB3-117BM engines running monitor the lI1B-500E vibration In-
dication annunciators.
(10) If in winter the engine oil temperature is minus 30-40°C before start it is
necessary to perform 2 engine crankings, with 3 minutes intervals be-
tween them.
(11) In order to ensure reliable start of the engines in winter at ambient tem-
peratures of _5°C or below after a prolonged parking period (for 24 h or
more) itis-necessary to crank the engines before start:
(12) Discontinue the engine start by depression of the START DISCONT
(nPEKPAIl.\EHlI1E 3AnYCKA) button and closing of the fuel shutoff valve
if at least one of the following events occurs:
(a) The FUEL FLTR CLOG L ENG, FUEL FLTR CLOG R ENG annun-
ciator is ON.
(b) The turbine inlet gas temperature rises above the limits indicated in
the graph of Fig. 3.3.
