Would it be possible to build a cannon that is launching satellites on the market?
Yes, it would certainly be; It has not yet been done. The concept of opening the satellite using the cannon was conceived in 1678 by Isaac Newton, in its principle Mathematica , where he used the concept of orbital cannon as a thought experiment to illustrate the principles of gravity. In 1865, Jules Verne, the father of the science fiction, wrote a story, from Earth to the moon in which a group of courageous men used a huge cannon to shoot to the moon. The Germans built a "Paris weapon", a 28 -meter weapon capable of shooting 105 kilograms of over 120 kilometers (75 million). The intention was to intervene the city of Paris from the security of the German border and the project was successful. Although the load was relatively small and the weapon was inaccurate, its main effect was psychological. It was the first time that such a gun was built.
The Germans also built superguns for World War II, such as the infamous railway weapon, Big Bertha, which was again used to makeParis submitted to the submission. However, large weapons have been shown to be relatively impractical for warfare because they demanded a large military protection department and were either stationary or slowly, which facilitates location and destruction through air strikes.
From the 1950s to his assassination in 1990, the Superguns field was dominated by one rogue physicist turned the seller - Gerard Bull. In 1961, Bull built 36 mm Cannon with the help of an American Navy and in 60 years used it to launch more than 200 atmospheric probes up to an altitude of 180 km (112 miles). This has determined the feasibility of using works to initiate useful load into suborbital trajectories.
Much later, in 1988, Bull was repaired by the Iraqi government of buildingbusupergun "Project Babylon": an extremely long artillery piece. Although the Bull was murdered before the weapon was completed, the weapon was built “BTo make Babylon "with a 45 m war and a range of 750 km (466 miles). The complete Babylon Guns project should be 156 m long, and if they work, it would be able to start a payload of 200 kg per rocket shell in orbit at a cost of only $ 600 (USD) for the incomplete Babylon weapon. Persian Gulf from 1991.
recently, in 2007, founded a visionary air engineer at MIT Ben Joseph the company called Ballistic Flight Group LLC to build the first cannon capable of launching the projectile in orbit. The aim is to use a combination of RAMJet technology and conventional cannons to start a payload of 2000 kg (4400 lb) in orbit. This is called RAM technology. As far as OPASS is going, this orbital cannon could reduce the start costs by factor 10, which reduced the current costs of about $ 5,000 per kilogram of a payload of about $ 500 per kilogram. Because the forces on the payload exceeds gravity 2000, it wouldn't be for people to get people into space, but it could be very useful to start stocks for space stations. The cost of the cannon is estimated at $ 157 million, which is relatively cheap according to the standards of current starting technology. It seems quite certain that eventually an orbital cannon will be built - it is a question of "when" than "if".
