Iranian Fish subsurface torpedo project, which was modeled after Ashkel in cooperation with Russia.
– 1 Sustainer with the highest length among the components of the missile
Acceleration up to cruise conditions and stable power generation for the rocket’s desired temperature
towards the goal. The sustainer of the Hoot missile itself consists of two parts
Is:
A) The accelerator engine while having a functional overlap with the rocket booster
In the final moments of its operation (after the pressure of the booster combustion chamber reaches
(35 bar with ignition function, lit and with thrust force generation
Approximately 18,500 Kgf in 1/3 of a second will increase the speed of the missile from 30 m/sec to
It reached 100 m/sec. After this engine finished its use
and was discharged as a part of the exit path of sustainer combustion products
is used. Accelerator engine fuel of solid type
It is double-sided, in the form of 12 grains each with a mass of 5.7 kg
It is placed in its place. These fuels have no insulation
Their combustion takes place in all directions. Sustainer nozzle cap
With 4 heat-resistant stainless steel pins in place
It is kept constant. In addition, on it, Oringi from
The material is SBR.
Sustainer green fuel accelerator
Accelerator bipod. Accelerator fire
b) The main engine of Ah is an engine with solid hydrogen fuel,
Almost at the start, the accelerator is turned on and the rocket accelerates
100 m/sec in the cruise phase. It is at this stage
The entrance of sea water through the middle channel of the missile and its continuous spraying through
Water injector nozzles into the combustion chamber, continuous continuous combustion
Findings and combustion gases exiting the Sustainer nozzle, production
The thrust force is approximately 4700 Kgf, and the missile using
This drift and the superavitation phenomenon reach a speed of 100 m/sec

1- Introduction of the sustainer of the Pisces missile:
It is one of the parts of the propulsion system of the Sustainer fish missile
It has two accelerating and hydroreactive parts. Acceleration section
The donor uses ballistic fuel with its short-term performance
It causes the rocket to accelerate up to 100 m/sec, while
The hydroreactive part, which is active for approximately 100 seconds, is the agent.
The steady movement of the missile is in the cruise phase and at a constant speed.

Huan separated
Location: Jasak Imamat base mission
Mamoret date: 10/30/82 to 11/21/82
The purpose of the HUR underwater rocket test mission (Ashkaval) a-3) 20 degree rotation according to the observation of proximity and
distance of the indicator from the place where the missile was found) performance power of missile sub-systems such as engines, gas generator, autopilot and missile control system have worked qualitatively. According to the mentioned qualitatively (the overall performance of the racket) test
It is considered successful.
B) missile accuracy
It is not possible to say about the accuracy of the missile and the possibility of hitting it at the present time
Kham gave a clear opinion. But it is necessary to mention the following points.
The place where the missile was found was 600 to 700 meters away from the index
It can be analyzed as follows
(1 – 2
300-550 meters
00 to 700 meters

According to the mentioned items, the accuracy of the test is qualitatively acceptable
(c) Missile exiting the water, because there was no talk about this before, so it is necessary to investigate it further. These two modes are considered to check it. C-1) before the main engine shutdown, which is not acceptable in any way and indicates the inability of the autopilot to control the missile. If it happened after the engine is turned off, it can be analyzed, while in this case, it has no effect on the accuracy of the missile’s performance or hit (2-8).

Chapter title
Analyzing the launch of the rocket after the main engine is turned off, the speed of the rocket decreases at a rapid rate when the main engine is turned off. until the speed of the missile reaches a point where the speed of the missile becomes unstable. One of the causes of this instability can be caused by the difference in bubble length in the upper and lower levels of the rocket. In this case, the rocket in the impossible direction
