2. These missiles use kerosene and nitric acid as fuel.
The fuel tank is composed of two concentric cylinders:'
(1) The inside cylinder, which has a circular section piston,
holds one of the two fuel components;
(2) The outside Cylinder, which has a ring piston, holds the
50X1-HUM
other of the fuel components.
When the fuelS are loaded into the tank, from the tail of the
missile, the pitons are thrust forward; when the tank is full,
the pistons are in a closed position, against a tank of compressed
air. .The compressed air thrusts the pistons towards the tail,
thus forcing the fuel through the nozzles. The compressed air
also serves to actuate the gyroscope and other instruments.
r with the nozzles is iodated in the tail.
the nozzles as like a flower sprinkler nr
watering can: one set in a circle and the second in a ring 50X1-HUM
surrounding the first. These two sets correspond to the twp
cylinders of the fuel tank, each set related to one cylinder.
The mixinglof the fuels then takes place in the discharge
chamber. A chemical catalyst, enclosed in a glass vial, is lo-
cated,in the discharge chamber and serves as a priming agent;
the catalyst is released by a small explosive charge and in-
stantaneously ignites the fuels.

4. The two sets of/nozzles (watering cans) .are pivot-mounted and ?
moved by an clic; possibly hydrodynamic7 mechanism
which ,is attached to the twir) pistons. The nozzle comTlex can be
adjusted to all possible angular positions in accordanee with
the linear position of the pistons. This mechanism thus controls
the orientation of the missile.
5. a. The missile path is controlled by radar (wave length approxi-
mately 3 cm). The radar signals transmit ground commands to
the missile.and also maintain the missile on its course. If
it should deviate from its course, as shown by a wavering
trajectory, the control mechanism brings it back on the beam.

b. In the missile there is a control called
(literally, rotator of coordinates); in fact, in tne missile
it is subjected to a spinning movement around its own axis, 50X1-HUM
whereas commands from the ground are related to a system of
coordinates fixed in space. The "rotator" is related to the
gyroscope: as the missile spins around its own axis, the
signals furnished by the gyroscope actuate, through a phase-
angle ("sfasamento") system, the "oleodynamic" control of the
nozzle complex; in this way, commands to the missile function
as if it were fixed in space.
c. The phase-angle system includes an RF oscillator which supplies
two signals at 900 to a special condenser with four dials;
the rotor of this condenser is molded in a special way and a
reading can be.obtained from it which always conforms precisely
to the momentary position of the axes of the missile with
respect to the axes of the gyroscope.
6. The "oleodinimico" control has a special needle valve which, in
essence, is the heart of the entire missile. So that this is not
clogged?for command signals, coming from a solenoid, there is
superimposed a sinusoidal-signal with vibrations; the small motions
that this effects on the needle of the valve are sufficient to
avoid clogging.
7. The electronic instruments, which are
(but not all of them), are located in
side the fuel tanks.. The antennas, of
place, are located in the nose and loo
there is also a fifth antenna mounted
antenna used for the retransmission of

9. The missiles have an overall external length of 6 or 8 meters. There
are two types: in Yugoslavia there are said to be about 100 of the
6-meter size and only two or three of the 8-meter miscues The
cruising speed runs about 9000 km/hour.
10. These missiles are consigned completely to the care of Yngoslav military
authorities at the present time. No special apparatus is neceSsary
to launch these missiles; a ramp can be mounted on a railroad car
or transported by truck in a convoy of vehicles on which are also
mounted auxiliary items for direction finding, control, and tele-
communications. In a convoy of this type there are 30 to .50
assigned personnel.
