AESIR, aka GFS Project
Unmanned Aerial Vehicle - Coanda Effect Aircraft





GFS Projects Limited was formed in 2002 to design, develop and market a new form of flying. Our Unmanned Aerial Vehicle (UAV) is based on the ideas and research of Geoff Hatton – the inventor.

Explanation of the Technology
Image of early test flight
If you take a piece of paper up to your lips and blow over the top the paper will lift. The reason for this is that the air velocity you create by blowing over the top creates a lower atmospheric pressure on the top than on the bottom, thereby creating lift.

This is known as the ‘Coanda Effect’.

By creating an air velocity in the centre of the craft with the aid of a fan and then directing the air flow out of the outlet it will follow over the curved surface. The amount of lift generated is dependant upon the velocity, mass and density of the air.
Control of the craft is in three sections.

Control of the craft is in three sections.
* Section one — anti torque.
The rotation of the fan causes the body to rotate in the opposite direction. By placing a series of vanes in the airflow the torque is neutralised.
* Section two — yaw control.
On sections of the lifting surface a series of moveable flaps, acting in unison enable it to turn left or right.
* Section three — directional control.
Flaps on the periphery of the craft provide directional control as the movement into the lift airflow changes, the lift causes the craft to tilt and move in the direction of the tilt.

The craft has a natural neutral dynamic balance making it very stable in flight and in hover.
