How the aqualung was invented?
the First aqualung appeared in 1943. It was the fruit of long thoughts of Jacques - Yves Cousteau and engineering thought of Emile Gagnan. Making use of a vastest experience of the diver with various self-contained units, Jacques - Yves could formulate requirements to the device precisely.
The engineer Emile Gagnan worked on a reducer for the engine working at gas mix at this time. He used the reducer for giving to the diver of air from cylinders. After a number not of absolutely satisfactory tests it gradually brought the device to the acceptable quality.
By this time friends moved to the general house, a country house of Barry on the coast of the Mediterranean Sea. They wanted to take place from which it would be easier to reach the sunk ships. Exactly here friends unpacked the first aqualung sent by Gagnan from Paris.
Cousteau wrote: “ We saw knot from three cylinders for compressed air of the moderate sizes connected to the air regulator of the size of an alarm clock. From the regulator two tubes attached to a mouthpiece lasted. By means of this equipment attached by belts on a back, masks in the eyes and a nose with waterproof glass and rubber flippers standing we intended to make free flights in sea " depths;.
Opportunities which were presented to them by an aqualung realized their dreams. They could soar freely in water, not too caring for air, hoses and ballast. Freely arriving air turned their lungs into a peculiar regulator of buoyancy. The breath - and a body, slowly, emerges, exhaled - falls.
First they just experimented: somersaulted, carried out under water of an aerobatic maneuvre, enjoyed feeling of soaring. They rejoiced as children. But soon they wanted bigger. They wanted to dive more deeply, to be under water longer, to set up new records, to get treasures of sea depths.
But they set higher objects for themselves. Not to chase records, and to study possibilities of stay of the person deeply, not to look for treasure, and to investigate archaeological values of the flooded cities and the drowned ships, not to string uncountable quantity of fishes on a harpoon, and to observe the hidden details of life of sea inhabitants.
In a word, not to snatch by the sea that will work well, and systematically to win it. Each subdued meter of depth gave to mankind three hundred cubic kilometers of water space. But it in the future for now they researched the ships which sank in this area.
During the summer of 1943 of Cousteau, Taye and Dumas made over 50 separate immersions and visited about fifteen sunken vessels. They wanted to prove that the aqualung is suitable too for works in which divers, that is for lifting the sunk ships and values which are on them usually are engaged. The way of the proof was known - they began to shoot the new movie which was called “ The Sunk vessels “. The English steamship " was their favourite object; Dalton “.
At the same time at the new qualitative level works on studying of physiology of underwater swimmers were resumed. They became guinea pigs, they consciously risked.
Works were carried out according to the strict plan. Each their step differing from previous was carefully analyzed. Necessary conclusions were taken, and only after that they went further, winning from the sea meter behind meter. Influence on people of pressure, composition of gas mixes which they breathed the modes and duration of stay under water was investigated.
In passing at the same time they set up world records, but did not disclose them, and not from modesty and not to cause a rekordomaniya wave. Already one it kept many thoughtless lives.
In 1949 friends wrote the book. It was called “ Immersion in a space suit “. In it use of an aqualung was for the first time described, the tables of immersions developed by its group are provided. In fact, it was the first textbook on diving.
In the book “ Immersions without rope “ for the first time published in 1954, its early underwater adventures are presented. Later this book was many times republished.
Subsequently the dozens of movies about underwater life were removed. These movies made huge impact on young minds. It is enough to tell that in the sixties only America totaled 1. 000. 000 amateur divers.
The boom caused by movies came also to our country. In the early sixties from our shops rubber rugs for bathtubs disappeared - the people made flippers and masks.
Fortunately, the industry unusually quickly reacted and began production of a factory set No. 1 - flippers, masks and tubes. There were also first domestic aqualungs. Numerous clubs of DOSAAF organized free training of persons interested in diving. The movie " came out; The Person - an amphibian “. By the way, Ikhtiandr in him swam on - dolphin, in Taye`s style.
