06:15 GMT, September 8, 2009 A new Vertical Take Off and Landing (VTOL) Unmanned Airborne Vehicle (UAV) is making its first public appearance on the AESIR Ltd stand, 2607, at DSEi being held at the Excel Centre, London, from 8 to 11 September 2009.

ASK is a 1.5 meter diameter craft fitted with an internal combustion engine. It has been designed to operate as an ISTAR platform, a logistics craft or as an aerial communications re-broadcast station.

Also on the stand is VIDAR, a 300 mm, man portable craft designed to provide surveillance and situational awareness inside buildings and in-close-confined spaces. It has an electric engine, 15 minutes endurance and can carry a 100g payload.

EMBLA is being shown in its counter IED role on top of a Northrop Grumman Remotec Mk 8 EOD Wheelbarrow, which has been adapted by having its manipulator arm removed and replaced with a platform for the UAV. EMBLA is a 600mm diameter electric engine craft which has been developed to show the capabilities of a Coanda effect VTOL UAV.

HODER is a heavy lift craft capable of carrying a one tonne payload. It is primarily intended for cargo transport but can easily be adapted to become a long endurance craft by reducing the payload and increasing the fuel. HODER is in the early stages of development but is expected that it will be multi-engined.

The VTOL craft utilise the Coanda effect to generate lift and have inherent stability as a surveillance platform. The design has no external rotating parts and can survive low speed impact with the ground, buildings and other fixed objects.

The AESIR UAVs provide a sustained hover capability, have a large payload capacity when compared to similar sized fixed wing craft and have been designed to use “plug-and-play” payloads resulting in considerable flexibility. Designed into the craft is an effective perch-and-stare capability.
