How does a hovercraft work ? | Design & Application

October 29, 2015

Human started with just wheels for travelling & transportation purposes at first. Then came bikes, cars & trains which could be driven on land. The next difficulty was to overcome the vast oceans & seas which led to invention of ships. Engineers are still finding ways to make today’s vehicles more better & efficient even though we have achieved success in almost every mode of travelling & transportation. One of the extraordinary machine in history of vehicles is hovercraft. Lets see how does a hovercraft work ? more “How does a hovercraft work ? | Design & Application”

Working of 4 stroke engine with animation

These are the most basic engines used in cars & bikes i.e Four stroke cycle petrol engine OR 4 stroke engine(often called). It is very easy to understand until & unless you wanna do all the thermodynamic calculations & all that stuff ! more “How does a 4 stroke engine work ?”

How do elevators or lifts work ?

September 13, 2015

Seriously, what would have happen if there were no elevators & if people were to walk up &  down a 50 or 100 storey building everyday in cities like NY ! I can’t even imagine the fatigue.

Well, keeping our thought aside, let us see how do elevators work ? more “How do elevators or lifts work ?”

Boeing’s new laser powered fusion-fission jet engine

July 15, 2015

Get ready, for this highly UNREALISTIC jet engine…
Boeing has received a patent, US 9068562, which combines inertial confinement fusion, fission, and a turbine that generates electricity. Currently this kind of engine is completely unrealistic given our mastery of fusion.

But perhaps in future this might be an excellent idea.

Lets imagine our standard jet engine of commercial jetliners.Somewhere in the middle of the engine lies a fusion chamber.A very strong number of lasers are focused on a single point.The hohlraum or pellet, which is a mixture of deuterium & tritium(isotopes of hydrogen) is kept at this point.When all the lasers are turned on at the same time, it creates massive pressure.This causes the hydrogen isotopes to fuse.Now according to the patent, the hot gases produced by the fusion are pushed out of the nozzle creating very high thrust.

Also, one of the by-products of the fusion reaction is lots of fast neutrons.The patent explains that there is a shield around the fusion chamber.The shield is made of fissionable material(for eg:-Uranium-235).The neutrons moving at high speed collide with this material resulting in production of high amount of heat.This heat is then transferred to drive the turbine which generates electricity.

Finally we are done with this fusion-fission jet engine thing.
