The "Habakkuk": the amazing story of a giant aircraft carrier
Material posted: Publication date: 21-04-2015
The Second World War has stimulated many technological advances. But one project stands alone in its scope. Every war gives impetus to the development of science and technology. The Second World War, of course, was the pinnacle in the history of military technology. In addition to hundreds of thousands of the most various innovations, which gave a powerful impetus to the development of military industry during the war developed a lot of the most imaginative projects that for various reasons have not been brought to its logical conclusion.

The design "Aeroplane carrier" of Avvakum »» was one of them. The aeroplane carrier and has not been floated, but that fact that over it two years of ten engineers and scientists seriously worked, says that this improbable and somewhere even the fantastic design had chances to be realised.

Surprise first of all calls a material from which volplaned to make "Avvakum". Unlike all other naval vessels it assumed to make from pajkerita, the frozen mix of water and sawdust. Sampling not absolutely usual material has simple explanation - Great Britain the same as also all other at war countries in military years tested a strong deficiency of metal.

The aeroplane carrier of "Avvakum" differed from usual courts of its class-room also sizes. Its length should make 600 metres, width - 90, and altitude - 60, i.e. about the 20-storeyed dwelling. This leviafan displacement of 1,8 million tons, on a plan of designers, should carry to 200 fighters Spitfire or one hundred bombers Mosquito.

The maximum speed of "Avvakuma" should make 7 knots (13 km/hour). It should provide 26 motor gondolas which have been built in in sides of a vessel. The fuel stock made 5 thousand tons and allowed it to pass without a refuelling of an order of 7 thousand miles (13 thousand in km). Well matched to sizes should be and a command of a giant aeroplane carrier: 404 officers and 3216 mariners.

The design also assumed presence of all repair shops and an other infrastructure, i.e. should form independent floating air-force baseline, some kind of military floating island.

The aeroplane carrier of "Avvakum" was a child of British originator Jeffrey Pajka which, by the way, was treated in … to psychiatric hospital and in the same place and worked over drawings and calculations. It is not surprising, because to the normal person such idea come to mind could not. The ration which has completed Cambridge, by the way, has dawned after paper perusal in National Geographic about icebergs. Especially strong impression on it has made that place in paper where difficulties of destruction of icebergs by means of an explosive are presented.

The design of an ice aeroplane carrier has interested the British Admiralty thanks n no small part to rather low cost. Because of cheapness of materials the vessel under the provisional estimate should cost no more 10 million pounds sterling.

Pajkerit has gained the name by name the originator who was not differing by special modesty Jeffrey Pajka. Raspings in number of 14 % were added in a mix that ice has not thawed.

The unusual material was easier and stronger than usual ice and thanks to raspings thawed much more slowly. Except the thermal insulation, in the ice case for protection against thawing serpentines of the powerful refrigerating machinery were provided.

After a row of experiments and tests pajkerit have started to make in Canada. At first water mixed with a groundwood on a smooth horizontal surface. Then by means of twirl it transformed into a thin layer in the thickness apprx. 1 see Then this mix froze cold air which scavenged through it. Naval vessel building needed in total 1,7 million tons pajkerita.

The idea very much was pleasant to the prime minister of Great Britain Winston Churchill. By the way, he has suggested to name an aeroplane carrier by name the antiquated prophet "Avvakumom".

The aeroplane carrier of "Avvakum" intended for patrol in cold waters of Northern Atlantic. It should accompany escorts. However at Quebec conference in August, 1943 an ice aeroplane carrier it has been decided to use in Pacific ocean for war with Japan.

Therefore building of an ice aeroplane carrier have transferred from east coast of Canada on the western. The prototype of "Avvakuma" has been built in the winter of 1943 on loch of the Patrician, Albert's province. It was the small model in length 18, width 9 and altitude of 6 metres. A wood carcase at first have designed on loch ice then it have filled with ice blocks. The refrigerating machinery which banished cold air on metal pipes, were in the central case. The model weighed apprx. 1000 tons and has been built within two months by a team quantity of 15 persons. The chilling system worked normally and allowed to maintain low temperature of ice till the end of summer.

In spite of the fact that prototype building has been recognised by successful and, appear, the design has a future, the economy and the finance has interfered with business.

After Quebec conference the American military men have started to look for at Pacific coast a suitable place for building of an aeroplane carrier of "Avvakum", but it has appeared that it is not enough platforms. Alaska was very farly, and the basic territory of the USA has appeared too warm ice block for building. On December, 16th the special commission which was engaged in searches of a site, has reported on difficulties on the heads. Having familiarised with very high labour cost and assemblage of other problems, chiefs of a headquarters of the USA and Great Britain have decided to refuse the design "Avvakum".

The prototype of "Avvakuma" on loch of the Patrician thawed the whole three years, proving that the idea despite all irreality was not such and impracticable.
