When speech comes about thrones, we imagine at once hi-tech kvadrokopter or military bespilotnik. But there are also more primitive devices, for example that the Robotics company created.
The team of engineers under the direction of Paul Paundsa from University of Queensland (Australia) developed a couple of pilotless aircraft of disposable use — in literal sense of this word. One is made of paper, and the second has a form of a maple sunflower seed. Both simple and inexpensive in production. Devices are intended for rescue of lives in case of forest fire.
Tiny bespilotnik are equipped with various sensors of environment which notify rescue services on change of atmospheric conditions that can point to fire distribution.
The first device looks as the ordinary paper plane, it only is made of a biodecomposed material on the basis of cellulose. Being thrown out from larger plane, so-called Polyplane continues movement in the set direction. The onboard control system directs a throne as it is possible closer to a landing place.
Advantages of disposable bespilotnik are obvious. They easy, cheap, possess good aerodynamic characteristics and do not put harm to environment as after performance of a task decay under certain conditions. All electronic components are put on the printed-circuit board with a jet method.
The second prototype simulating the helicopter, is called as Samara. It is made of the same biodecomposed material. Samara less operated, than Polyplane. Owing to the design the device rotates in air as a maple sunflower seed, slowly landing on the earth. Obvious plus here is lack of need of installation of expensive system of landing.
Meanwhile, Germans hope that thrones will protect their railways from vandals.
