why don't the scientists use the explosion as a fuel for the spacecrafts or ultra modern aircraft which will b

Answer 1

Because there is too much that could go wrong. It's hard to have an explosion in a confined space and not go out of that space.

Answer 2

The answer is quite simple. A human body has the capacity to withstand acceleration only to a max of g4 which is a unit of acceleration used for such purposes. However the escape velocity which is 11.2km/s. In a rocket it is taken to that velocity slowly as the rocket moves up. So the acceleration is quite less. However in explosion oriented launching the rocket gets all that velocity within a second or less. Thus the acceleration is beyond g4 beyond human capability to withstand. In more simpler words, it can be done but the human inside it will be dead, with all his body parts hanging loose when he is at the orbit.
So practically your idea is not applicable.

Answer 3

What explosion? Do you mean combustion? The way rockets and even car engines work is through use of a controlled explosion called combustion - you'll notice when a rocket launches there is fire coming out of it - that's part of the explosions that are pushing the rocket forward.

Answer 4

Experiments for rockets that could fly very large distances at high speed using nuclear power used precisely this principle - a series of rapid small explosions. However, this was in the days before fallout was realised to be so nasty, and it has the problem that its a bit jerky.

Answer 5

are u trying to ask that why arent chemicals in bombs etc are used as fuels instead of the petroluem etc that we use?
in that case, todays combustion engines are much the same. they all carry out miniature explosions in closed compartments. that is the bang you hear when u start a motorcycle.
the feuls we use are in a liquid state. hence they can flow easily.
the combustibles used in bombs are powdered. they cant flow easily.
the flow and amount of liquid fuel used can be controlled. there are chances, that the fraction of powdered fuel to be used my exceede the limit and cause accidents.
the basic mechanism of any engine is to trun combustion enrgy into kinetic energy.
if very prcisely calclated designs are made, someday it might be possible to use the very same materials that are in bombs to fuel ur motorbike, or to launch a spacecraft.
but even then tehy wont be preferred coz of:
1. high cost
2. high polution rates
3. low fuel:energy ratio.

Answer 6

There is an old, old design for a rocket that uses small nuclear bomb explosions as propulsion. It was called the "Orion". Never built, of course.

Answer 7

i think you mean 'jet gas' with the help of 'oil'... there have been experiments to capability an airplane with organic gas, hydrogen, or maybe nuclear gas cells. All of those have been helpful, yet not worthwhile / secure.

Answer 8

explosions will increase vibrations.Present day technology is not sufficient to protect them from huge vibrations.For controlled only rockets r exploding and concorde flights have been cancelled so we have to wait to see in future nuclear powered space crafts which can travel from planet to planet.hope those will be available for our next generations.

Answer 9

your thinking is intelligent but very poetic!listen the explosion is a product of liquid oxygen and hydrogen.so it cannot be used in the same way as you cannot cook something out of incense stick's ash.

Answer 10

maybe they are worried that an explosion will damage the aircraft.
