The Universe has always exerted a magical Fascination on Humans.The importance of Space-Travel will increase dramatically in the Future.But how do Humans or Satellites get into Space?
Currently only by means of Rockets. In order to reach outer Space - i.e. to reach an Altitude of more than 100 km above the Earth's Surface - one needs a Propulsion System that can generate the necessary Power to overcome the Earth's Gravity and still function in a Vacuum. The only known Mechanism that meets both Conditions is a Rocket.A Rocket Motor exploits the physical Law of force and Counterforce "actio = reactio": When the Rocket ejects a Mass Backwards at high Velocity (this is the Action), it produces a forward thrust in Reaction. In today's Rocket Engines, the Energy required to accelerate the ejected Mass is provided by the Combustion of a chemical Fuel; the Oxygen used for this is carried in a separate Tank.Due to the enormous Quantities of Fuel, the Ratio of launch Weight to Payload is extremely unfavorable for a Rocket: It is 2.8% for the European rocket Ariane 5 and only 1.3% for the American space shuttle. An Ariane with a launch Weight of 700 t can therefore Transport a Payload of just 6 t. In order not to have to build rockets all the time, the space glider returning to earth was developed. However, the hoped-for major savings did not materialize, partly because of fuel and maintenance costs.What engines will the spaceships of the future have?
The big challenge is to overcome the force of gravity. To do this, incredible efforts are being made, with extremely poor efficiencies.To escape this dilemma, a technique has been developed that also uses the repulsion principle, but where the actual fuel remains on the ground and does not have to be taken into space.This system is called LightCraftIn theory, it works in a fascinatingly simple way.A highly energetic laser beam explosively vaporizes a material in the drive chamber of the object to be transported - thus the recoil is generated and the object moves away from earth.Targeted laser shots are fired at the material in the combustion chamber until the desired height is reached.Once this technology is able to shoot larger weights into space, it will revolutionize the entire space travel.Our thermosolar power plants produce a large amount of electricity, so that we could transport several objects into orbit every day without weakening the normal energy supply.One would store the electricity produced during off-peak periods.If we succeed in developing such a cheap means of transportation into space, travel into space will become commonplace.Once one has escaped the earth's gravity, one continues with electric propulsion in space. Light-Craft would not only be an extremely cheap system, but also absolutely environmentally friendly, because it is essentially powered by solar energy.The development partner will be DLR, which has already gained considerable experience with light-craft technology.We will continue to report on this exciting new technology here.
