The Engineeringity

Leonardo da Vinci sketched once in his notebook in 1514. The parachutes were reinvented in the late of 18 century in 1783  but credit for the first invention of the first practical parachute goes to  Frenchman Sebastian Lenormand, the man who imposed the word Parachute.

Parachuting | Para jumping


    What is the history of Parachutes?

    In the early years of our present century, a group of Government and military men gathered to evaluate the possibilities of a new vehicle for use by the army. 

    When the air age began many of the early designs were not the most reliable aircraft in fact some of them proved themselves to be no aircraft at all. 

    But man was determined to fly at the beginning of the air age. Keeping this in mind, in the future if aircraft were successful then safety parachutes would have an important role.

    When did Parachutes first come into use?

    It was also inevitably the beginning of the widespread development of the parachutes, as in late World War I, most American pilots did not wear parachutes. But as air Warfare developed the French and the issue of the German-made regulation among the pilots. 

    In the year just after World War I one of the parachutes in America remained as a device for barnstorming stuntmen, but by the early 1930 Russia looking ahead to the time when America needed shock troops for its global plans to begin experimenting with the parachute for military use. 

    This experiment was not confined to human parachutes but included vehicles and weapons. 
    The vision of the future role of the parachute in military operations was clear.

    Experimenting of Parachutes

    The experimenting continued to work out the complicated two-stage canopy which would bring their paratroopers down at greater speed, a smaller top slowed the fall for most of the distance than a larger square-shaped canopy open to cushion the final approach to the ground it was interesting and it worked but it never came into widespread use.

    The working out of the early method for cargo drop was started in which the parachute was dropped before the cargo. They even tried dropping man vehicles without the benefit of parachutes wonders some attempts were successful it became clear that parachute was the most practical means of air-to-ground delivery.

    How Parachutes helped in World War

    parachutes in military | safe landing parachutes

    During World War II the parachute found a great many other uses vast areas of the enemy shipping lanes were seeded with mines from the air with the parachute to slow their descent and prevent detonation for landing shots.

    Towards the end of the war, the Germans came up with an unusual Ribbon chute design to act as an air brake for dive bombers and gliders.

    In Korea techniques for parachute delivery of vast masses of combat material.

    The big nylon umbrellas had brought a great change in the concept of military supply tons of essential combat material could be delivered over distance in terms of land transport. 

    The importance of parachutes in making possible this high-speed large-scale delivery is virtually impossible to exaggerate.

    Seat ejection Parachute technique

    seat ejection parachuting technique

    With the development of supersonic aircraft, parachutes' escape techniques had to change.
    The seat ejection parachute was about to come in to be in initial testing involving men, as well as machine seat ejection, would have had to be swift, but not so Swift that pilot could not bear the acceleration stresses.

    Naziz had worked on an ejection seat design and captured German. So the testing, designing, and refining went on in the search for a way to give a pilot and his parachute a protective package as a self-ejecting package that would give him clear a supersonic jet in a hurry and with safety.

    The ejection technique came into practice

    It was a tough problem but the solution was found and the ejection seat principle was proven in practice.

    Still, parachutes had added a margin of safety to the flying of Jet aircraft special breaking chutes are standard equipment on many jets. Giving pilots the ability to land safely in a much shorter way than they could otherwise use.

    The regulus Supersonic submarine missile is a good example, a missile is recoverable because it can be guided tour landing escort aircraft and because it uses a rugged nylon canopy to slow its conserving stop once it touches down because it carries on recovery parachute to bring it and its cameras down gently.

    Adaptation of parachutes

    Pararescue teams need special parachuting skills and they practice them often, the right timing for slipping the harness in a water-resistant comes only with the experience of taking a jump over thick woods to battle a forest fire.

    A man needs to know how to land in treetops and come out in one piece. In countless other situations as well where relief could come only from the air, the parachute has brought supplies and comfort to those cut off from help.

    Parachuting as sports

    Recently a lot of attention has been given to Parachuting as a sport in both military and civilian. 

    Skydiving is called and clubs have sprung up everywhere, perhaps it isn't likely to replace baseball as the National pastime but few sports fans can claim, the thrill parachuting gives the skydivers. 

    The parachute has been brought into a whole new field of techniques and given a new type of modern Army.

    Airborne soldiers of today must know everything that classic infantrymen had to know and a great deal more about the added training, the added mobility, and the added striking power resulting come from the full development of the parachute's ability to deliver both assault rifle troops and combat supplies.

    Conclusion

    The parachute has truly come a long way from the early days of the Baran storming Daredevils to its 100 uses in the world of today.

    Even if the space age opens up ahead it seems safe to speculate that parachutes are dependable versatile umbrellas of the sky.

    Hydrogen gas or H2 is a gas that contains a lot of chemical energy if you Ignite it, it will react with the oxygen in the air and release its energy using an explosion, and the only waste product is water. No CO2 nor any toxic gases just a bit of water. Of course, the uncontrolled explosion is great fun but how to properly use hydrogen as a fuel to power machines and vehicles, such as cars, well to do that we use a Fuel cell Hydrogen Fuel Cell.



      What is Hydrogen Fuel Cell?

      A hydrogen fuel cell is a device that takes hydrogen and oxygen and uses those to create electricity but how exactly does a fuel cell work let's find out.

      How does it work?

      Hydrogen Fuel Cell |working of Hydrogen Fuel Cell | What is Hydrogen Fuel Cell
      Hydrogen Fuel Cell

      The schematic diagram shows a Hydrogen Fuel cell in which on the left is the Anode and on the right side there is a Cathode, the anode, and the cathode are hollow areas in which gas can be sent inside, this is where the hydrogen gas goes and the oxygen goes into the cathode in between them there is a catalyst and an electrolyte(Proton exchange membrane).

      What happens when the system is turned on?

      When the system is turned on we get hydrogen in the anode and oxygen in the cathode, now the hydrogen inside the anode wants to go to the other side to meet with oxygen, and then react with it to form water. 

      But there is a problem with it, H2 cannot get to the other side because there is something between them the Electrolyte(Proton exchange membrane). The electrolyte is a material that only lets positively charged things get through it. 

      Why can't Hydrogen go through electrolytes?

      To know the reason behind it we need to go into the depth of hydrogen, A Hydrogen is not positive. A hydrogen atom consists of one proton and one electron one positive particle and one negative particle making the overall particle neutral.

      So the hydrogen in our system is neutral and not positive so it cannot go through the electrolyte. However, there is a solution to it which is the Catalyst. Now, what the catalyst does? 

      In this case, it does the splitting of electrons from the protons so that electrons of the hydrogen atoms are removed from their protons.

      So now we have got a bunch of protons and electrons, protons are also known as h+ which can pass right through the electrolyte because they are positive and they can meet with oxygen on the other side.

      Generation of Electricity

      But there is a problem, you see these are just protons and not really hydrogen anymore, so they can't react with oxygen and form water. 

      To do that the electrons that are still on the other side must be transported over to the cathode first you might have noticed that words I used electrons and transported, and for transporting or moving electrons there is a name for that which is Electricity. 

      That's right moving electrons is what we called Electricity, so we can simply connect a wire-like shown in the diagram, and then the electrons can simply able to float right through the wire to the other side, and they will meet up with the protons and can react which oxygen to form water which can leave the system and now what we have obtained is electric current running through a wire which we can then used to power a light, the bulb, a motor.

      This is how the power output of the fuel cell is obtained.

      Where are these Fuel cells used?

      Hydrogen fuel cells are useful in automobile industries. Hydrogen is arguably safer than gasoline, so safety isn't a huge concern for hydrogen.

      Currently, several companies around the world are working on the development of hydrogen cars.

      Advantages

      Hydrogen is the most abundant and readily available source of energy. To support zero carbon emissions hydrogen is one of the best alternatives and one of the clean energy.

      As it is having the highest calorific value it will be more powerful and more efficient. It is more efficient than many other green energy solutions. 

      One of the most important advantages is that it has a fast charging time compared to many other combustion engines.

      Drawbacks

      Now although the cell is such a clever invention does have some drawbacks, 

      First of all, it gets really hot when it is in operation and this can lead to fuel cells potentially damaging can themselves if it is cooled properly.

      Another disadvantage of a fuel cell is it is very expensive you can remember that catalyst we talked about that is actually made out of platinum which is of course so very expensive.

      Conclusion

      So now you know how a Fuel cell works. But keep in mind that Fuel cells are different from battery cells. I hope you enjoyed reading this post.

      What do you think will Hydrogen Fuel Cell be the future of electric vehicles?

       It all starts with the IBM personal computer, the most advanced computer machine ever created. However, this isn't the story of the computer. But a story about when computers stop working. The man who created a way started all over. The man who invented Control-Alt-Del.



        Who created Ctrl-Alt-Del?

        Control-Alt-Delete | David Bradley founder

        He was Dr. David Bradley. Back in 1980, he worked in IBM's personal computer. His particular job was writing basic input outputs in systems. Even with an elite team of engineers and designers, not everything goes smoothly when you build a computer. 

        The programs that ran most of the time got failed the only way to reset the system was to turn the power off and wait a while to turn the power back on it would go through a very long self-test but the system might die every 5 to 10 mins.  It was not easy.

        Where did Ctrl-Alt-Del come from?

        What he needed was away, shortcut to restart the process. One thing that came out after their discussion was to put a Reset Button on it but if a reset button was put on the system board there was a chance that if it could hit by mistake then all the data would get lost.

        Many engineers worked on it but could not find a solution. So after many attempts, the solution they came up with was a three-key sequence that would reset to this computer.

        And a new coding hits by mistake a single Control key a single Alt key, and then all the way over at the right-hand side a single Delete key when you hit Control-Alt-Delete, You're are deleting everything that you're working out right now, and starting new. 

        Wasn't it great at that time to come up with this invention?

        When does it get popular?

        Even though it was built only as a development tool, programmers began incorporating the features in their applications from there it was released into the while but didn't immediately reach pop culture status for years it was no big deal.

        Then suddenly on the 20th anniversary of the IBM PC that's when Ctrl-Alt-Del became a sort of cultural icon the reason behind this was Bill Gates, it was the simplest and easiest way to fix your problem and hit control alt del start all over.

        Now, this is very interesting on asking Dr. David about his invention.

        Interesting answer by Dr. David

        the history of Ctrl-Alt-Del | Meme on Ctrl-Alt-Del

        On asking Dr. David about his invention Cnt-Alt-del, he answered that he got a lot of things with IBM but all everybody remembers is CONTROL-ALT-DELETE. But taking the fame of CONTROL-ALt-DELETE means he worked on a very successful Product.

        The man did this invention when he was in his 40s and now he is 71.

        Things to learn from this invention

        Inventing new things from the existing ones was not an easy task at that time. But what we can learn from this invention is that,

        There is always a solution to a problem trying to solve may find a way.

        There is always a Way you only have to find the Will.
