Over the last 3 years, IAT21 (the Austrian Innovative Aeronautical Technology research company) has been working on the designs for a totally new form of airborne auto-motion, as revolutionary as were the jet engine and the hovercraft

How D-DALUS works
At the heart of D-DALUS is a revolutionary propulsion system containing a number of patented inventions, including a friction free bearing at the points of high G force, and a system that keeps propulsion in dynamic equilibrium, thereby allowing the guidance system to quickly restore stability in flight.
The propulsion consists of 4 sets of contra-rotating disks, each set driven at the same rpm by a conventional aero-engine. The disks are surrounded by blades whose angle of attack can be altered by off-setting the axis of the rotating disks. As each blade can be given a different angle of attack, the resulting main thrust can be in any required direction in 360? around any axis. This allows the craft to launch vertically, remain in a fixed position in the air, travel in any direction, rotate in any direction, and thrust upwards thereby 'gluing down' on landing.
i always thought thats how UFO's would work.

So, it's like a helicopter except useful for tennis playing.
Sounds great.
