A catcher in an object-oriented environment of AWE is an interface with the outside world. It can be compared to the keyboard on which the wind plays. Refusing the idea of mechanical traction, the main task of the catcher becomes quite obvious: the conversion of wind energy into electricity. Even assuming as an optimal some other, non-electric way of transferring energy to the ground, it is difficult to imagine a device that could directly convert wind energy into a given optimal form of energy, bypassing the electrical phase. This applies to the transfer of energy by the laser, and the electrolysis of water with the release of hydrogen and transfer it to the ground. And of course this applies to cases of delivery of containers with an electric accumulator or electricity through a waveguide. I knowingly omit the method of transmitting electricity over conventional wires, as it did not justify itself in well-known projects. You can not discount the possibility of using electrical energy on site. These tasks include coverage of the territory under AWE, organization of communications, surveillance, filling stations for quadrocopters. Thus, there is a clear task of creating a flying electric generator. Among the variety of wind energy converters in electric generally recognized as an optimal scheme is the rotor. And the flow direction must coincide with the axis of the rotor. Thus, the blade machine is used as much as possible, and, consequently, the material consumption is minimal. It is clear that for a flying electric generator this is a key characteristic. Several well-known projects went along this path. Makani In fact, this is a plane with a propeller engine working as a generator. In it there are advantages, for example rigidity of a design. But if such a device is placed stationary in the air, then the blades operate in a non-accelerated flow and they become too heavy. Altaeros The device is stationary, the flow is accelerated. But at what cost? A gas container forms a confuser. At first glance – a brilliant solution. But if we calculate how much helium costs and how much it escapes through the complex configuration of the balloon, then the idea becomes economically unjustified. The second problem is a great drag, and therefore a more powerful lift is required. The third problem is the need for a more durable guiding device in the throat of the confuser. It also increases weight. Roderick Read Project The blading is as light as possible for the swept surface. The task remains to locate this device at a height where the winds have a high speed. What’s next? The following scheme seems to be the most optimal.
