ACG Carbon Prepregs Applied to AESIR’s Unmanned Autonomous Systems

Composite carbon prepreg materials from Advanced Composites Group Ltd. (ACG) are being utilised by AESIR to manufacture the fuselage of its ODIN, HODER and VIDAR Vertical Take Off and Landing (VTOL) Unmanned Air Vehicles (UAVs).

Using patented AESIR technology, AESIR’s UAVs are able to function in urban and rural environments and are suitable for a variety of uses, such as surveillance and lifting cargo.

ACG’s MTM 28 Series prepregs are based on a 85 to120°C, curing, toughened, epoxy matrix resin, specifically manufactured for components requiring high damage tolerance. AESIR say that these were preferred because of their strong impact resistance, autoclave curing capability and long lifesppan.

In this application, AESIR opted to autoclave cure its UAV fuselages, but ACG say their MTM 28 Series prepregs can accommodate vacuum bag or press moulding.

AESIR’s ODIN VTOL UAV, which is the company’s median product, measures 1m in diameter, weighs 10kg and has a payload of 10kg. It is powered by a Wankel Rotary engine, which burns JP-8 jet fuel, giving it a one hour operational capability. The HODER VTOL UAV, which is currently at prototype stage, is a heavy lift craft capable of carrying a one tonne payload.

Typical operational roles covered by the AESIR range include: ISTAR (Intelligence, Surveillance, Target Acquisition and Reconnaissance), situation awareness, communications relay and electronic warfare, fixed and mobile asset protection, IED (Improvised Explosive Devices) detection, weapon or loitering munition, stores deployment and any other operation where using a manned craft might put a crew’s life at risk.
