Space Simplified

S o thermodynamics says that no engine can be 100% efficient, it means that we can't possibly make an engine which can convert all the energy that is stored in its fuel into usable work. We are going to produce some waste in the form of heat. This wast heat has to be dumped out of the engine or else the engine will melt. This fact doesn't just apply for engines but for any type of mechanism as well. Cooling on earth is a fairly simple thing because most things are cooled by the air, anything which can't be cooled statically by air has to aided by a air radiator. Basically the heat from a heat source is absorbed by a coolant which then carries the heat into a mesh of coolant pipes (an water to air heat exchanger) which increases the surface area in which the coolant through the pipes is exposed to the air. A fan can be added to up the flow of air. This is a very simple liquid cooled system which works for most kinds of things on earth.If more cooling is required then we can

  Nuclear power among the stars P ower generation in space is a very complicated task, actually power itself isn’t the issue but how do we get rid of the waste. Usually for smaller missions batteries, fuel cells or solar panels are enough but for more extensive missions we need more power. The life support systems for more than 4 people and sensory equipment’s require a lot of power and on a high voltage. A very necessary concept to understand about power generation is that there is not atmosphere. Atmosphere is very important for engines on earth to work as they are not just important for combustion but are also the medium in which the engine dumps its exhaust and its heat. Heat is a big issue in engines as there are very few engines which even reach the thermal efficiency of 50%, this means that most engines are able to convert Less than 50% of the energy stored in its fuel. The rest of the energy is dumped out as heat some of it is released through exhaust gas and the rest through

  Full Flow Staged Combustion Engines   Ok so rocket engines are weird, the action of mixing fuel and oxidiser is simple in theory but in practice its way more complicated. So starting from the beginning the first rocket used to be solid rocket boosters so fuel isn’t a big issue in them. The problem with solid rockets is that they are not efficient enough, enters liquid fueled rockets. Liquid fueled rockets are more efficient can carry more cargo up to higher speeds all good, the problem is how do we pump the fuel.   So rocket engines need something to pump fuel and oxidiser into the combustion chamber. At first   engines were pressure fed basically the pressure inside the fuel tanks will push the fuel in the engines. This was a very simple system got the job done but as the fuel is kept under pressure the skin of the rocket has to be very durable (and heavy) to hold it in which is bad. Enter turbopumps, turbopumps are well pumps which pump the fuel in the engine but it has t

O n 9th September 2021 one of the biggest and most influential automobile manufacturers closed all operations in India. The company in question if Ford Motor Company the biggest manufacturer of America automobiles. The big, muscular cars offered by ford were a breath of fresh air from the tech savvy German and the average Japanese cars. Ford was among the few remaining companies that offers a supercharged V8 which is largely extinct in the rest of the market also Ford is probably the only company to offer jet black as a factory colour scheme. From the very beginning days of Ford in Mr Hendry Ford’s workshop in Detroit, thought two world wars and the financial crises Ford has stood strong against its rivals. The success formula for Ford has remained the same from the days of its founder that is Standardisation, mass production and the weight of American steel. Ford has made past crash test standards simply by having a thicker steel body also the big V8 in spite of its thrust can be redu
