The Craziest Aircarft In The World


The Craziest Aircarft In The World

Kalinin-K-7-3
The craziest aircraft where actually the ones created in the 20th century! When a new idea comes out it really gets much attention and people experiment with it. Check out this aircraft something your eyes wont believe.



Kalinin K-7 is a giant bomber design in 1930′s! Idea of the Russian army in the 1930′s, when jet propulsion wasn’t even recognized. It was a top secrets of the Russians then, now some Russia the flying and history lovers intend to reconstruct it. You can see their design pictures, really cool aircraft!trans The Craziest Aircarft In The World

Kalinin K-7  was a heavy experimental aircraft designed and tested in the Soviet Union in the early 1930s. K-7 was of unusual configuration with twin booms and large underwing pods housing fixed landing gear and machine gun turrets. In the passenger version, seats were arranged inside the 2.3 meter (7 ft 7 in) thick wings. The airframe was welded from KhMAchrome-molybdenum steel. The original design called for six engines in the wing leading edge but when the projected loaded weight was exceeded, two more engines were added to the trailing edges of each wing, one right and one left of the central passenger pod. However V. Nemecek states in his book, The History of Soviet Aircraft from 1918, that there was only one further pusher engine added; this agrees with the specification supplied far below.
Designed by World War I Aviator Kostyantyn Kalinin with a wingspan close to that of a B-52 and a much greater wing area, the K-7 was one of the biggest aircraft built before the jet age. It had one engine fewer than of the B-52 as well, having an unusual arrangement of six pulling on the wing leading edge and one pushing at the rear.

The K-7 was built in two years at Kharkiv starting in 1931.
The K-7′s very brief first flight showed instability and serious vibration caused by the airframe resonating with the engine frequency. The solution to this was thought to be to shorten and strengthen the tail booms, little being known then about the natural frequencies of structures and their response to vibration.
K-7 first flew on 11 August 1933. The aircraft completed seven test flights before a crash due to structural failure of one of the tail booms on November 21, 1933.The accident killed 14 people aboard and one on the ground. Although two more prototypes were ordered in 1933, the project was cancelled in 1935 before they could be completed.
In 1938 Kalinin was executed as an enemy of the state.

How Big Is Seawise Giant?
Overall, she was generally considered the largest ship ever built. Additionally, she is considered to be the largest mobile man made object ever built. She was last used as a floating storage and offloading unit (FSO) moored off the coast of Qatar in the Persian Gulf at the Al Shaheen Oil Field.
The vessel was sold to Indian ship breakers, and renamed Mont for her final journey in December 2009. After clearing Indian customs, she was sailed to, and intentionally beached at Alang, Gujarat, India for demolition.

Seawise Giant
Seawise Giant was the longest ship ever constructed, longer than the height of many of the world’s tallest buildings. Though slightly smaller than Taipei 101 at 509.2 metres (1,671 ft) and the Willis Tower at 527.3 metres (1,730 ft) from street level to top of antenna, she is larger than the Petronas Twin Towers at 452 metres (1,483 ft).
In spite of its great length, the Seawise Giant was not the largest ship by gross tonnage, ranking fifth at 260,941 GT, behind the four 274,838 to 275,276 GT Batillus-class supertankers. The Batillus class and the Seawise Giant were the largest self-propelled objects ever constructed.

The Suez Canal


It is recorded that Egypt was thefirst country to dig a canal across its land with a view to activate worldtrade.
The Suez Canal is considered to be the shortest link between the east and thewest due to its unique geographic location; it is an important internationalnavigation canal linking between the Mediterranean sea at Port said and the redsea at Suez. The idea of linking the Mediterranean sea with the red sea by acanal dates back to 40 centuries as it was pointed out through history startingby the pharaohs era passing by the Islamic era until it was dredged reachingits current condition today.
It is considered to be the firstartificial canal to be used in Travel and Trade. The Whole Idea of establishinga canal linking between the red sea and the Mediterranean dates back to theoldest times, as Egypt dredged the first artificial canal on the planet’ssurface. The pharaohs dredged a canal link in between river Nile and the redsea.

The inscriptions in the tomb of Wenithe Elder, who lived during the 6th Dynasty of the Old Kingdom (c. 2407-2260BC) tell us a lot about Egyptian canal building and the reasons for buildingthem - (for war ships and for transporting monument stone). Scholars are stilldebating, however, whether his waterways ran all the way from the Mediterraneanto the Red Sea.

The first canal was dug under thereign of Senausret III, Pharao of Egypt (1887-1849 BC) linking theMediterranean Sea in the north with the Red sea in the south via the river Nileand its branches.

The Canal often abandoned to siltingand was successfully reopened to navigation by Sity I (1310 BC),Necho II (610 BC), Persian King Darius (522BC), Polemy II (285 BC), Emperor Trajan (117 AD) and Amro Ibn Elass (640 AD),following the Islamic conquest.

Under Necho II , a canal was built between thePelusian branch of the Nile and the northern end of the Bitter Lakes (which lies betweenthe two seas) at a cost of, reportedly, 100,000 lives. However, over manyyears, the canal fell into disrepair, only to be extended, abandoned, andrebuilt again.

Necho was the first who attemptedthe channel leading to the Erythraian Sea (Red sea and Gulf of Suez which wasextended to near by Ismailia city), which Dareios the Persian afterwardscompleted: the length of this is a voyage of four days, and in breadth it wasso dug that two triremes could go side by side driven by oars; and the water isbrought into it from the Nile. The channel is conducted a little above the cityof Bubastis (near by Zagazig city) by Patumos the Arabian city (Near byIsmailia city), and runs into the Erythraian Sea: and it is dug first along thoseparts of the plain of Egypt which lie towards Arabia (Eastern desert), justabove which run the mountains which extend opposite Memphis (south of Cairo),where are the stone-quarries,--along the base of these mountains the channel isconducted from West to East for a great way; and after that it is directedtowards a break in the hills and tends from these mountains towards thenoon-day and the South Wind to the Arabian gulf (Gulf of Suez). Now in theplace where the journey is least and shortest from the Northern to the SouthernSea (which is also called Erythraian), that is from Mount Casion (east of PortSaid), which is the boundary between Egypt and Syria, the distance is exactly athousand furlongs (1 furlongs equals about 200 meter) to the Arabian gulf;but the channel is much longer, since it is more winding; and in the reign ofNecos there perished while digging it twelve myriads of the Egyptians. NowNecos ceased in the midst of his digging, because the utterance of an Oracleimpeded him, which was to the effect that he was working for the Barbarian: andthe Egyptians call all men Barbarians who do not agree with them in speech.
After having been neglected, it wasrebuilt by the Persian ruler, Darius I (522-486 BC), whose canal can still be seen along the WadiTumilat. According to Herodotus, his canal was wide enough that two triremescould pass each other with oars extended, and that it took four days tonavigate. He commemorated the completion of his canal with a series of granitestelae set up along the Nile bank.

This canal is said to have beenextended to the Red Sea by Ptolemy II Philadelphus (285-246 BC), abandoned during the early Roman rule, butrebuilt again by Trajan (98-117 AD). Over the next several centuries, it onceagain was abandoned and sometimes dredged by various rulers for various butlimited purposes.

Amro Ibn Elass rebuilt the canal afterthe Islamic takeover of Egypt linking the Nile to the Red Sea creating a newsupply line from Cairo . It was used for shipping grain to Arabia and to transportthe pilgrimages to the Holy Land. The canal was stopped up in 767 AD by theAbbasid caliph El-Mansur to cut off supplies to insurgents located in the Deltaand to starve out rebels in Medina.

In modern times the Suez Canal isactually the first canal directly linking the Mediterranean to the Red sea.

The first efforts to build a modern canal came from theEgypt expedition of Napoleon Bonaparte, who hoped the project would create adevastating trade problem for the English. Though this project was begun in1799 by Charles Le Pere, a miscalculation estimated that the levels between theMediterranean Sea and the Red Sea were too great (estimating that the Red Seawas some ten meters higher than that of the Mediterranean Sea) and work wasquickly suspended.

Napoleon was told that the Red Seawas 30 feet higher than the Mediterranean. Dig a canal, his surveyors said, andthe Red Sea will hemorrhage into the Mediterranean.

Napoleon's engineers alsoconsidered the idea of a canal running directly between the Red Sea and theMediterranean, but they miscalculated a difference of ten meters between thetwo sea levels and gave up the idea, and it would sweep away the Nile Delta.

Then, in 1833, a group of Frenchintellectuals known as the Saint-Simoniens arrived in Cairo and theybecame very interested in the Suez project despite such problems as thedifference in sea levels. Unfortunately, at that timeMohammed Ali had little interest in the project, and in 1835, theSaint-Simoniens were devastated by a plague epidemic. Most of the twenty or soengineers returned to France. They did leave behind several enthusiasts for thecanal, including Ferdinand de Lesseps (who was then the French vice-consul inAlexandria) and Linant de Bellefonds

In Paris, the Saint-Simonienscreated an association in 1846 to study the possibility of the Suez Canal onceagain. In 1847, Bourdaloue confirmed that there was no real difference in thelevels between the Mediterranean and Red Seas, and it was Linant de Bellefondsthat drew up the technical report. Unfortunately, there was considerableBritish opposition to the project, and Mohammed Ali, who was ill by this time,was less than enthusiastic.

In1854 the French diplomat and engineer Vicomte Ferdinand Marie de Lessepssucceededin enlisting the interest of the Egyptian viceroy Said Pasha in theproject.
In 1858 La Compagnie Universelle du Canal Maritime de Suez (Universal Companyof the Maritime Suez Canal) was formed with authority to cut a canal and tooperate it for 99 years, after which ownership would return to the Egyptiangovernment. The company was originally a private Egyptian concern, its stockowned chiefly by French and Egyptian interests. In 1875 the British governmentpurchased Egypt's shares.

The pilot study estimated that atotal of 2,613 million cubic feet of earth would have to be moved, including600 million on land, and another 2,013 million dredged from water. The totaloriginal cost estimate was 200 million francs.

When at first the company ran into financial problems, itwas Pasha Said who purchased 44 percent of the company to keep it in operation.However, the British and Turks were concerned with the venture and managed tohave work suspended for a short time, until the intervention of Napoleon III. Excavationof the canal actually began on April 25th, 1859, and between then and 1862, thefirst part of the canal was completed. However, after Ismail succeeded PashaSaid in 1863, the work was again suspended. After Ferdinand De Lesseps againappealed to Napoleon III, an international commission was formed in March of1864. The commission resolved the problems and within three years, the canalwas completed. On November 17, 1869 the barrage of the Suez plains reservoirwas breached and waters of the Mediterranean flowed into the Red Sea and thecanal was opened for international navigation.
Completion of the 160- kilometerlong waterway, however, took ten years of excruciating and poorly compensatedlabor by Egyptian workers, who were drafted at the rate of 20,000 every tenmonths from the ranks of the peasantry.

The completion of the Suez Canal wasa cause for considerable celebration. In Port Said , the extravaganza began with fireworks and a ball attendedby six thousand people. They included many heads of state, including theEmpress Eugenie, the Emperor of Austria, the Prince of Wales, the Prince ofPrussia and the Prince of the Netherlands. Two convoys of ships entered thecanal from its southern and northern points and met at Ismailia. Partiescontinued for weeks, and the celebration also marked the opening of Ismail'sold Opera House in Cairo , which is now gone.

Because of external debts, the British government purchasedthe shares owned by Egyptian interests, namely those of Said Pasha, in 1875,for some 400,000 pounds sterling. Yet France continued to have a majorityinterest. Under the terms of an international convention signed in 1888 (TheConvention of Constantinople), the canal was opened to vessels of all nationswithout discrimination, in peace and war. Nevertheless, Britain considered thecanal vital to the maintenance of its maritime power and colonial interests. Therefore,the provisions of the Anglo-Egyptian Treaty of 1936 allowed Britain to maintaina defensive force along the Suez Canal Zone. However, Egyptian nationalistsdemanded repeatedly that Britain evacuate the Suez Canal Zone, and in 1954 thetwo countries signed a seven-year agreement that superseded the 1936 treaty andprovided for the gradual withdrawal of all British troops from the zone.

The canal remained under the controlof two powers until Nasser nationalized it in 1956; it has since been operatedby the Suez Canal Authority .

The canal was closed to navigationtwice in the contemporary period. The first closure was brief, coming after thetripartite British-French-Israeli invasion of Egypt in 1956, an invasionprimarily motivated by the nationalization of the waterway. The canal wasreopened in 1957. The second closure occurred after the June 1967 War withIsrael and lasted until 1975, when Egypt and Israel signed the seconddisengagement accord.

After July 1952 Revolution,president Gamal Abd El Naser publicized the canal in announcement in (26 July,1956) making the management of the canal a 100% Egyptian, which enraged themajor countries leading to the Triad assault on Egypt in (29 October, 1956)which caused to the closing of the canal and it was reopened in (march 1957).

Advantages of the Suez Canal


Advantages of the Suez Canal
  • It is the longest canal in the world without locks.
  • The accidents are almost nil compared with other waterways.
  •  Navigation goes day and night.
  • The Canal is liable to be widened and deepened when required, to cope with the development in ship sizes and tonnages.
  • With the adoption of the Vessel Traffic Management System (VTMS) ( a system depending upon the most up-to-date radar network), vessels can be monitored and followed on every spot of the Canal and intervention in emergency cases can be taken.
  • The Suez Canal accommodates the partially loaded VLCCs and ULCCs .

Importance & Advantages of The Canal


Importance of the Canal
  • The Suez Canal is considered to be the shortest link between the east and the west due to its unique geographic location; it is an important international navigation canal linking between the Mediterranean sea at Port said and the red sea at Suez .The unique geographical position of the Suez Canal makes it of special importance to the world and to Egypt as well.
  • This importance is getting augmented with the evolution of maritime transport and world trade. The maritime transport is the cheapest means of transport, whereas more than 80 % of the world trade volume is transported via waterways (seaborne trade). 
  • Saving in distance , time and in operating costs for vessels that transit the Canal, also firm up this importance.


Historical Outline:
  • Egypt was the first country to dig a man-made canal across its lands to connect the Mediterranean Sea to the Red Sea via the branches of the River Nile. The first who dug it was Senausert III, Pharaoh of Egypt (1874 B.C.). This canal was abandoned to silting and reopened several times as follows:
- Canal of Sity I
1310
B.C.
- Canal of Nkhaw

  • The Suez Canal is actually the first canal that directly links the Mediterranean Sea to the Red Sea.
  • It was opened for navigation on the 17 th of November 1869.
  • Egypt nationalized the canal on the 26 th of July 1956.
The Canal was closed five times; the last time was the most serious one since it lasted for 8 years. The Canal was then reopened for navigation on
