Abstract: Space travel is one of the fields in
which even the byproducts of the inventions made
are very much useful to the world. This concept
strives to approach space travel with a new
perspective that might be contradictory to the
conventional thinking process.
Index terms: physics of explosion,space, concept of
space explosions.
INTRODUCTION
Space travel,from ages has been one of man’s
prime areas of interest. His quest to explore the
universe has begun but has not reached his targets
yet. Technology that he gets is limitless but he is
limited by his speed at which he cruises through
the heavenly bodies.The intention of this idea
proposed is to have a fresh look at space travel
which may be contradictory to the conventional
methods. This method may be the answer for
achieving high speeds as well as distances
traveled.
I.PHYSICS OF EXPLOSIONS
A.Explosion:
An explosion is a rapid increase in
volume and release of energy in an extreme
manner.All this energy released is equally
distributed into nature either by sound or heat or
imparting kinetic or potential energies to particles
associated with the explosion.
B.Energy:
when a bomb explodes, the energy is
distributed as follows
Total energy =heat energy+sound energy+ energy
imparted to the fragments associated with the
explosion.
The energy associated with the fragments is a
very small fraction when compared to the total
energy. This energy is in the form of kinetic
energy.
The energy imparted to one fragment will be
E= 1/2*m*v2
m= mass of the fragment
v=velocity of the fragment
If there are ‘n’ equally sized particles, the energy is
multiplied by the number of particles
n*E = n*(1/2*m*v2
)
Since the energy is fixed, the velocity of the
fragment and hence the distance traveled by it can
also be determined.
About 75% of the energy of an explosion is
converted to heat or sound and only 25% of useful
energy can be used for generating the kinetic
energy.
An explosion can be controlled by controlling the
causes of explosion.
Factors or causes may be materials used for
creating the explosion, the atmosphere around the
explosion etc.
Control over an explosion is needed because :
a.To prevent damage or action that is not
necessary.
b.To control the amount of debris during the
explosion.
c.The debris control is a key feature to this
proposal.
The Munroe effect (classical definition: conical
space at the forward end of a blasting charge to
increase the explosive's effect and thereby save
powder) can be used to obtain shaped charge to
obtain a focused explosion on a fragment and
thereby transferring more energy to focused
fragment.

The above figure is a simulated graphical model
of Munroe’s model for shaped charged
The explosion preferred for this application is by
nuclear detonation as the energy is very high. Such
high values of energy are needed to provide
sufficient kinetic energies.
II.SPACE
Space is a perfect podium for the demonstration
the Newton’s laws of gravitation.
First law:
A body continues to be in a state of rest or of
uniform motion until or unless compelled by an
external force.
Space has the minimum friction and hence a body
continues to move with uniform velocity in a
straight line when a force acts on it.
Second law:
The force exerted on the body is equal to the
product of mass and acceleration gained by the
body.
Third law:
Every action has an equal and opposite
reaction.
 On earth or any planetary surface, the
newton's law cannot be perfectly
demonstrated because of various factors
mainly friction.
 Friction occurs due to relative motion
between two objects and hence tends to bring
the relative speed between the objects to zero
 On earth, atmosphere and land are the biggest
sources of friction for any moving object
 In space, There is no land or atmosphere. It is
mostly vacuum
 the only elements of friction in outer space
can be other heavenly objects irrespective of
sizes.
 In space,if any object is applied with a force
then it will accelerate to a certain level as per
the Newton’s second law which states that
F=m*a.
 Now, after it has gained that acceleration,it
will move with a constant velocity forever in
a straight line until another force tries to
change it's course.
 Hence no more fuel is required is outer space
in accelerating the object (in this case, a space
shuttle).
III.CONCEPT OF SPACE EXPLOSION
 The whole universe is believed to be formed
by the big bang theory which implies that a
big explosion created the universe.
 The energies and thereby the velocities of
heavenly bodies were distributed during the
big bang.
 The idea is to reinstall the same big bang
theory but on a smaller scale when compared
to itself.
 A controlled explosion can produce not only
debris as per calculation but can also achieve
velocity of the focused part of explosion.
 The Idea is simple. By focusing an explosion
in outer space, we can achieve better speeds
for space travel.
 Consider an analogy of a hand grenade.
 A certain time after the pin is removed from
the hand grenade, it explodes.
 The above explosion is not focused.
 A few modern grenades have focused
explosion (hollow charge) for maximum
damage.
 An explosion that can be shaped by Munroe’s
effect and can be focused on a specific
fragment which can be a satellite or any space
travel vehicle.

 Consider the explosion of a focused grenade.
 Rather than considering the damage caused
by the focused fragment, consider the speed
achieved and distance traveled by it.
 This can be calculated by using laws of
energy and kinematics.
 The fragments from normal grenade can
travel as far as 200m from the site of
explosion with a damage range upto 6m..
 Bigger the focused fragment, more will be the
energy gained by it and hence more will be
the acceleration gained and distance traveled
by it.
 Consider a space shuttle as a focused part on
a huge grenade i.e. whose explosion is
focused on the space shuttle.

 Consider an explosion to occur in such a way
that proper protection is offered to the shape
shuttle.
 The space shuttle along with its protection
gear is arranged as a single fragment.
 Hence, the space shuttle fragment will get the
energy out of the explosion.
 The source of explosion to be nuclear is
explained as follows:
As told earlier,
E=1/2*m*v2
Let m=1000kg
v= 50,000kmph (say)
Substituting the ‘m’and ‘v’ values
E= 1/2*(103
)*(5*104
)2
=25/2* 1011
=12.5*1011
Joules
=1.25TJ (TeraJoules)
(1 Joule= 1 N*m2
/s2
)
(1TJ=1012
J)
Similarly,
S.No. Velocity to be attained
(x*10,000kmph)
Energy to be
supplied
(TJ)
1 6 1.8
2 7 2.25
3 8 3.2
4 9 4.05
5 10 5
The blast yield of the “fat-guy” nuclear bomb
(That destroyed Nagasaki during the world war-II )
is 88TJ.
From the figure (weapon energy distribution) it can
be seen how the energy is distributed.
Hence the yield energy is distributed into three
parts and energy more than the required (1.25TJ) is
obtained even if the energy usable is 2.5%.
This is for one fragment of the explosion. For ‘n’
fragments the total usable energy gets distributed.
The energy used by the remaining fragments =
total energy - energy imparted to the focused
fragment.
(2.5 percentage of 88TJ =2.2TJ)
 Hence the required velocity is achieved.
 Going by the analogy, a focused grenade is to
be built so that it can be exploded by a remote
control.
 In our case, a space shuttle is the focused
fragment of the grenade.
 The remote control here is a ground station.
 The grenade is built entirely in space.
After the explosion:
 Enormous amounts of matter gets destroyed
 Since all of this is in space, Newton's space
can be applied peacefully.
 The unfocused fragment gets its part of
energy and departs from the grenade.
 A part of the energy is focused on the focused
fragment and hence is delivered to it.
 The energy as per the law will provide a
acceleration to the fragment with which it
will move in a predefined straight line.
 Hence the path of shuttle is set.
Problems faced with this method and possible
solutions:
1.Material:
A. The material to make,not the bomb, but to
construct the shaped charge model can be collected
from the space debris.
B. If space debris is not a viable options,the
resources from the heavenly bodies can be utilized.
2.Survival of the temperatures:
A. Bigger shell which will act as a protective
measure to the space vehicle.
B. Starlite. The product of plastic that can
survive upto 10000 degrees centigrade. Coating
the space vehicle with multiple layers of starlite
should suffice the need.
3.Secure location for the explosion:
A. There are lot of empty spaces between

planets. Detonating a nuclear bomb in these spaces
will do either no damage or no considerable
amount of damage to the planets or other
celestial bodies.
Advantages :
1.Since this entire explosion takes place in
space, minimal damage is done to the planet.
2.Velocities that are greater than that achieved
by the existing propulsion systems can be attained.
3.More number of shuttles can be sent for
space exploration at a single go.
4.The above can be done by increasing the
number of focused parts. (setting up a pipeline
from the source of energy and the shuttle(s))
5.Can be used to travel farther distances in
space.
