Nuclear-propelled missiles
(
!!!!!!!!!!!!!!!!!!
The fuel is heated by a nuclear reactor, the machine
that produces nuclear energy. And this energy
generated produces a thrust of up to 3-4 times the
energy produced by solid and liquid fuels, and
scientists are working to develop these rockets to
travel in space and pump liquid hydrogen to the
reactor of these rockets, through a double wall
surrounding the rocket engine, this pumping helps
cool the rocket, and the liquid hydrogen also heats
through hundreds of narrow channels, which pass
through the nuclear reactor, where liquid hydrogen
passes through these channels, and the transfer of
heat to the nuclear reactor
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
3. It is a type of missile, which is launched from one
place on the surface of the earth, to fall on another
place on the surface of the earth, and freedom here
means that the rocket from the moment of its launch
cannot change its course during its flight until it falls
on the target, by any means of control on the ground
or from the air, because the missile is struck (angle of
direction, angle of elevation with corrections for
weather and topographic conditions) before being
launched to reach a specific purpose or target, and
the missile launches and hits with this initial guidance
the intended target
B. Guided Rockets
They are missiles whose trajectory can be controlled
during flight, after launch to change this trajectory,
whether launched from land, air or sea stations, and
there are several methods of guidance as follows
:
)
1
(
Inertia Guidance
4. The guidance group of the rocket includes a group of
gyroscopes and computers, which modify the
trajectory during the flight of the missile, as a result
of the initial data on the computer, and the results of
the calculations extracted from it to match the
pre-calculated path, by issuing the necessary signals
to special stirring units, either moving the rudders,
which move in front of the gas rushing from the
combustion chamber, or moving the chamber itself, or
moving external units (fins)
.
On the stirring units are installed feedback units,
which extend the steering system

(
Routing with navigational routes
This is done by providing the guidance device in the
missile with the data of the planned route to reach
the target, avoiding various means of detection, and
following the method of low and very low flight,
5. because of the presence of a curve monitor, and a
camera that takes a picture of the target to compare
it with the image stored in the missile, and make
adjustments before colliding with the target
.

(
Satellite-assisted guidance
This is done by providing the missile with the planned
itinerary programs to reach the target, and satellites
are used to determine the coordinates of the missile,
during its flight, and conduct

Partition according to type and launch base
A. Surface-to-surface missiles: from a fixed or moving
base on land or from a naval piece to a land or sea
target
.
B. Underwater to surface missiles: from a submarine
to a sea or ground target
.
c. Surface-to-air missiles: from a fixed or mobile
6. ground base or naval piece to a flying target (aircraft
or missile)
.
d. Air-to-surface missiles: from the aircraft to a sea or
ground target
.
e. Missiles from air to underwater: from the aircraft to
an underwater target (e.g. submarine)
.
f. Air-to-air missiles: from the aircraft
