Small remotely operated vehicles are designed to add agility and playfulness of traditional systems and cultures, surveillance cameras or sensors. The British company AESIR, who created the collection "plates", believes that it will find many applications, from agriculture and conservation to military operations and facilities.
A new type of UAV with vertical take-off does not have any external moving parts (not counting the small plates for deflection of the air flow) and therefore, without any fear can fly about the branches of trees or wires of power transmission lines. For weight loss significant part of the structure is made of carbon fiber.
The fan in the center of the machine used to create flow of air around it. But unlike a number of machines of type "screw in the ring" itself, this thread does not create a reactive lifting force. And fan blades here too not operate on the principle of the helicopter rotor.
Instead both lift in the car from working AESIR Coanda effect (Coanda effect) — sticking phenomenon of a gas jet (or fluid) to a curved wall when feeding them through the narrow channel. (Under water this effect is, for example, must work Russian bike-submarine.)
In this case, the jet adheres to the curved outer surface of the housing. It creates vacuum, enthralling "UFO" up. Separate regulation of the air flow in different sectors of the "plates" allows it to bend and change course.
The company has developed several related models, differing in size and type of engine. So, for example, the smallest — Vidar. Apparatus with a diameter of 30 cm weighs 400 grams and can lift 100 grams payload. Its fan is spinning electric motor receiving current from lithium batteries. In the air the machine can be 15 minutes.
Meter diameter Odin has wakelam consuming jet fuel JP-8. This "plate" weighs 10 kg and raises the same load. In the sky she held an hour.
In development is an even larger machine. Hoder should weigh 1.5 tons, lifting into the air a ton of payload. Mission time up to 8 hours. The main purpose of this device is the Autonomous delivery of ammunition and medical supplies to the front, while the "lesser brothers" — born scouts.
The official presentation of the family of a British "UFO" took place at the arms fair Defence Systems & Equipment International 2009, held a few days ago in London.

AESIR built several versions of their "plates". Above shows a 60cm electric Embla. Below is another instance of the same apparatus on the military robots Northrop Grumman Remotec Mk 8 Plus II Wheelbarrow in the role of launch platform. To the right is another test prototype, and below is the layout of the Vidar. Bottom two images: working prototypes of the AESIR ASK (a 1.5-meter apparatus of the internal combustion engine) and dual-fan "truck" Hoder (photos AESIR).
