1. On the front side of the turbine-disc ring a atop is.
provided and in the labyrinth sealing of the turbine is added the
fourth comb for limiting the gas flow into the apace of engine
rear .bearing.
The turbine 'body has no. centering collar and for lighte-
ning it has milled grooves betweenibeholet on flangeli for bolts.
Analagous milled grooves are on the rear flange of outer ring of
the gas guide Vane ring.
Instead of the jet pipe, extended jet pipe and discharge
. nozzle to the body of the turbine through the telescopic joint
the afterburner is fastened with a remote controlled discharge
nozzle, having a hydraulic Control system. The thermocouples for
measuring.of the exhaust gases temperature are placed in the
afterburner.
;.Engine auxiliaries drive box is calculated for mounting
of fuel pumps PN-91.1,1 and PN-14A. The box has a deaerator on the
side mall with e draining neck,. the box cover is of trial form.
The parts of auxiliaries drives and of the centrifuzal J eparaccr

principle of function of the /Inane.
The air enters the com7.re83or 4 throwth tis front and rear
intake branches 2 /fig.6./ each of them has three guide vane',
serving for diminishing of air .flow losses on the intake and for
a proper directing of the airflow. Thereafter. the air runs into
the intakes of blade wheel and farther into channels .of comprcs-
sor blade wheel 4, Where it?la_sompressed. Then coming there-
. .
from, air With great speed runs into the diffusor, where the
speed-energy of air is transformed into pressure energy. From
the compressor the compresied air rues into the. combustion
Chambers 6 of engine through .aine inlet elbows of combustion
chambers, in each of them there are three guide vanes 3, placed
in a ran and serving for booing of the air flow and for .
lessening of losses of air flow energy in the place where the
air flow0)ows.
' Fuel is injected. under pressure through the working
burners into the inner shells, mounted inside the combustion
chambers. During bur.ling ofethe fuel there if consamed
approximately 25 per cent 'of air, coming into the combustion
chambers. The remaining quantity of eir,mixed with the products
. of burning, lowers the gas temperature to the value, at which
.? the engine runs reliably. Fuel is "completely bdrnt in the
combustion chambers and the gases oricinated by the burning,
flow . through the guide vanes to the turbine bla des. 2. The
? greater amount of nerd of gases is .absorbed for driving of ?
the compressor 4 by intermediary of the turl.ine. From the ?
-
turbine are driven also.. the cooling fan 5 and the auxiliaries,

aircraft auxiliaries drive box. The remaining energy of the

gases is used for i...:eneration of thrust, is con:?are.1 with onlr
jet engine, the WIC-11 engine has afterburner 11 instead of the
jet pipe. Fuel,intended t3 be burnt in the afterburner, is
injected by.24 burners against the direction of the gas,flowir.5
auto! the turbine. The reliable burning Of fuel in the zas
? stream after the turbine is impossible without additional
.
equipment - flame stabilizers. The stabilizers are necessary
for keeping the flatness front and their surface And thus for
. securing a steady and continuous burning. The stabilisation of
the burning in the-afterburner of the. engin* ViK-.IF is secured
by formation of return strelms of gas in the tear-off zone,
behind the ring Shaped stabilizer 10 and in:ler cone 9, mounted
in the widening part of- the afterburner. The injected fuel :
begins to burn after the stabilizer and ends in general before
the-gas passes through the jet nozzle. The gas temperature
increases by this up to 1500-1590 degree Centigrade.
U the afterburner has A widening part 665 mm long,the
41r flow .is allowed to decrease its speed in the combustion zoni
? and thus, in spite of 4 relatively short afterburner 4 complete
combusiion of-fuel is secured. The afterburner is engaged, i.e.
fuel is talented and burnt there only an when. an increased
--thrust must be secured. During the remaining time, the
10
afterburner ser .7
ves as di jet pipe. In accordance with it, the
conditions of operation of the afterburner are varying. In e.
'order to secure in both Cases a stable gas temperature after
? . the turbine, the afterburnetle provided with an- extensible jet
? nozzle 12, which has two cross-sectional areas. Then the
additional-4641 injection is OFF, the extensible jst nozzle is
set. into the position with minor cross-sectional area.

ENGINE ROTCii.
The engine rotor consists of rotor of the compressor, rotor
of the turbine, clutch, which connecte both rotor, and bodies of
the bearings: the front, centre 'and, rear one, which serve as
supports for rotor of compressor and of turbine. The rotors of
the compressor and turbine rotate in three bearings, two of which
are roller type /the front and the rear one/, and which allow for
en' axialdilatation of the shaftsand bodies during operation of
the engine, and one is bail-type /the centre one, whieh holds the
?rotors of compressor and turbine in the axial direction and which
receives the axial load from the turbine.
Rotor, of the Compressor.
Rotor .of the compressor Rig. I/ consists of a blade wheel
of the. compressor 11, two air intakes /revolving guide apparatus/
10 and. 12, the front and the rear /7 and 14/ shaft of compressor
and the. fan blade wheel. The front shaft of the compressor. is
hollow, made of steel alloy. In front of the shaft a journal is
provided for the front roller bearing 4 and the thread for its
fastening by the nut 1, on the rear end there is a conical stripe
for fitting of the front intake 10 and a flange,which together
with the flange. of the front intake is fastened by eight stud
bolts 9 to the compressor blade wheel.Inside, from the side of
the bearing, the abaft has evolvent spline?, through which, by
intermediary of the Bylined ?end the revolution is transmitted
to the cogged wheels of the engine auxiliaries -drive box. The
rear Shaft of compressor, i made of steel alloy and is also hollo?,
On its' surface it has splines with rectangular cross section for

In the housing of the rear bearing a port of the air es-
capes between the longitudinal diaphragms 8 and by blowing around
the seat, it lowers the temperature of the outer ring of the rol-
ler bearing. The remaining volume of air passes through clearances
between the turbine shaft and bush of the turbine shaft, cools
the inner ring of the roller bearing. After having passed from
the housing of the rear bearing, air lasses bnween the vent de-
f-lector 9 and the turbine disc -10 and takes off some hent from
the turbine disc. In oder to prevent the rear bearing housing
from being heated. by this air, there is fitted a heat insulation

CHAPTFR
Compreasor.
A
The engine compressor is a one -at ?w.7e , doable -entry centrifu-
gal tyle with a compression ratio of 4,42.
The purpose of the conressor is to compres?s the air before
entering the combustion chambers. The ms.cimum output of the comp-
ressor at n-1156 0 r .p.m. ano a temper ature of -t 15?C is 49,2 kg/
sec. The maximum .ndaber Of revolutions of the com,ressor impellnr
is 1156 0 r.p.m. The compressor rotor is being rotated during the
starting procedure. by means of an electric St arte motor, during
the operation- by means of the turbine rotor.
The air flows through two air entry vanes the front and the
rear one, ihto the ducte of the compressor impeller. From the in-
: pellet the air proceeds through a vaned diffusor Ina nine compres-
nor discharge elbows into the combustion chamber. "
Front entry vanes Mig.17/ ? consists of tInme straightening
.cones 3, ring 4, wall 1 and 48 Straightening vanes 2, placed at th
inlet. These vanes serve for preliminary straightening of air
with the purpose of decreasing the relative velocities and dinini.

AFIFFIBURNr:.R. '
r The afterburner serves for obtaining ? an. additional thrust
of the engine by additional combustion of fuel, in.jected into the
afterburner. The afterburner is a pipe, made. of heat-resistant
steel 1Ch1801` and consists of three parts. welded to each other:
the widening part 1, the tapering part 2 and the cylindric part 3
ig? 36/ ?
The Widening Part of the Afterburner.
In the widening part 1'the gas stream speed is reduced and
the additional quantity of fuel is ignited and burnt here. The
. widening part of the afterburner is 3 cutoff cone, which by its.
smaller base is fastened through a telescopic joint to the body
of engine turbine. -The telescopic joint allows mutual axial shif-
ting and deflection of the afterburner axis from the engine 'axis I
both at engine run and at assembling /fig.37/. The telescopic joint
consists of a cylindrical flange 4, which together with the an-
nular deflektor 5 is fastened to the rear flange of turbine body,
?..
and of the ring '6, welded to the afterburner. The flange of the
telnseope and the annular deflector have each 72 holes for faSte-
nine bolts 7 and 72 millcd grooves for reduction of weight.
The annular deflector 5 protects the 'telescopic joint against
the gas gusts. On the widening part of the afterburner on the outer
surface aiheat-insulating cover 8 is put for reducing of heat trans-
.mission into the neighbourhood. On the outer surface of the
ning pat on the peripyrry four flanges $1 are welded os for the
? fastening bolts of the inner cone /fig.35/.
The heat insulating cover i'see fig. E/ is. a cut-off hollow
cone made of steel shent 1Thl.P.N9T and has 40 stiffening channels

The hydraulic sy. stem serves for. controlling the controllable

.1. reline control system if ig.48/ consists of 3 hydraulic cylin.ders
- ;tom the aircraft system the hydraulic liquid is brought under
pressure approximately 150 atm to the iletrohydraulic valve nA-13.
The GA-1-i: valve has a twee-position slide valve, controlled by
electromagnet. When the engine operates without afterburner,' the
hydraulic liquid from the electrohydraulic valve is directed un-
der pressure through the pipeline 3 and connects the hydraulic
. system of the airer aft with cavity "3" of the hydraulic cylinders.
Thus, the hydraulic liquid in the hydraulic cylinders remains .un-

directed into the cavities "I". The pistons .of the hydraulic cy-
linders under pressure ?of.the hydraulic liquid are Shifted. into
extreme rear position together with the fairing cowl, by which
the gills are released. This position corresponds to the raaximum
opening of the ceintrollab-le Jet nozzle.
For synchronous action of the power cylinders in the system
the jets 4 are mounted. The synehronous action of the hydraulic
cylinders and time of motion of the cowl is adjusted by choosing
a proper set of jets when the engine is tested on the teat bad.
The power jack and the jets are marked after test lay the same ?
chiffre. The power jack /hydraulic' cylinder/. ifig.49/ is made of
? steel 3CChGSA as a hollow body 1,? in the cover of whieh a hole
with three antalar grooves is provided, into which three rubber
sealing rings 2 are fitted for tightening of the place. Inside .
the cylinder is a piston 3, the rod of which protrudes through
? the cover of the cylinder outside from it.The piston divides the

cavity of the cylinder into two parts and for neventing of lea-,
kage of the liquid from one cavity into another two grooves are
provided?in the piston, in which rubber sealing rings 4 are inT
serted..In the cylinder.a plug 5 is inserted, on which there are
two outer and two inner grooves. In these grooves rubber sealing
'rings 4 and 6 are inserted, which serve as sealing, yreventing
the hydraulic liquid from leaking?out of thr cylinder. The plug
ie fastened on the cylinder by the nut 7. Into the plug the front
fork 8 is screwed in, which limits the travel, of the piston awl
serves for fastening of the cylinder to the bracket of the atter-

2/ The isodromic regulation is a system of indirect automatical
regulation with elastic back-effect, which secures maintaining
of the vented rating of engine with an insignificant residual
error or without it.
The isodromic regulation was adopted originally for main-
taining of constant speed of revolution of machines, to which
it owes its name.
Owing to favourable qualitites of this system it was adopted
also for -regulation of pressure, temperature, fuel supply, direc-
tion control of ships and for other purposes.
In the PET-9MA pump the isodromic regulator Lmpreves the
regulating procedure, to e.maintains the constant rotational
speed as it has been desired through the whole range of automatic
regulation with variation of altitude and of oir-epeed.

the operation of the pump without overheating. Pressure before
the needle 78 of the distributor ART-14A drops, the needle '

, Fuel in the-low power channel proceeds into the whirr cone'
14 and,: after having got into right-hand ,spiral, is ejectecl'in
atomized state through jet 12 into the combustion chamber. 'Fuel
in the main channel runs to the whirl. ring 11; where it gOta-.into
tiright-hand spiral and through the.armult clearance between the ? ."
cOncentrically set jets 10 and 12 it is dispersed. into the ?cors- ? ?
bUstion chamber. Then both channels are in-operation, the fuel on
the outlet from the burner 13 forned? into one. united atomized
stream. The jets are divided according to their output capacity
' into ttree group3 as folloWs: ?
Group. 0 from 377 to 3:37 litres, per hour
Group. .a from 3)2 to 400 litres per hour
Group B from 410 to 4113 litres per hour
Change of output of the jet is adjusted by choosine a proper
thickness of the atomizing ring. The hydraulic resistance of the?
fuel collector channels is practically insignificant and therefore
output of the burner does not depend on where the burner is
placed-on the -fuel collector and the burners are interchangeable
within the 3 re _group.
Fuel Collector /see fig.56/.
The fuel collector consists of the main and auxiliary lines,
having, nine branches each, leading to the corresponding hoses ,which
? deliver fuel into channels of working burners. The fuel collector
is cede of pipes, forming four halt-circles, two of which f.orm, the
Rain-fuel 'system end the other two ? the auciliary one. The pipes
Ore connected by union nuts to the necks of the fuel Collector
bracket ; The fuel collector bracket has a neck for connection of
the hose of the pickup, by which the fuel pressure before the
burners is measured, and two necks for connectionl of hoseS,leading?

of generator drops, the voltage of the.generator increases and.
consequently the electromagnetic power of the regulator .is in-
creased, too. In result of this, the armature approaches the ,care
of the electromagnet and reduces-the thrust on the carbon pile,
? by which the exciting current of the generator will drop and ? vol-
Loge of generator will be limited. The armature of the regu
lator settles dean in a new position, appropriate for the new
working conditions of the generator. New balancel of forces is fl-
yen by increased electromagnetic thrust and opposedly increased
thrust of the springs, caused by their deeper deformation,
;Then the rotational speed of the generator drops or the ?
. ?
load is increaseed, voltage of the generator will d.rop and con-
sequently the regulator of the electromagnet will lose part of
its power. In result of this the armature goes away from the
core of the electromagnet and increases its thrust on the carbon
? pile, by Which the exciting current of the generator will be in-
creased. Drop of voltace will be stopped and the armature of the ?
electromagnet will get into balanced condition in a position,cha-
? racterised by lover electromagnetic thrust and ?lower opposed thr
of the springs. This new position of the armature is appropriate
