Hmmm... ----- PysOrg.Com http://tinyurl.com/6afchjz Austrian Company Debuts Revolutionary Wingless Aircraft by Bob Yirka "A firm from Austria, Austrian Innovative Aeronautical Technology (IAT21) has unveiled a new type of aircraft that flies without wings or rotors, at the Paris Air Show. Though not actually flown at the show, spokesmen for the new aircraft, named D-Dalus (no doubt after the tragic Greek figure Daedalus, who lost his son Icarus when his wings melted as he flew too close to the sun) claim the aircraft is capable of both hovering and flying forward as fast as a jet, all with very little noise." ----- =46rom the company webpages: http://start.d-dalus.at/?page_id=3D9 ----- Fixed wing drones certainly play their part. But those capable of large payloads are costly, require large launch and recovery platforms and are limited in their ability to dwell on target. They lack stealth, maneuverability, range and endurance. They cannot enter buildings. Rotary wing drones can take off and land in a relatively small space. But they are challenged in bad weather, at long ranges, at high speed and in operating to and from lurching platforms such as vehicles in battle of boats in rough weather. The external rotors present a hazard and a strong signature. Those capable of large payloads are usually costly and complex to maintain. Ideally we would love an aerial platform that can approach as gently and silently as a hot air balloon, can stay in the air like a humming-bird, can rotate in any direction like a football, can 'glue down' on the deck of a ship like a 'tossed pancake', can see in all directions like a crystal ball, can fly as fast as a jet, is as invisible as a 155mm shell and can be repaired by a local car mechanic. Such an aircraft now appears within reach. 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=B0 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. The current status of D-DALUS D-DALUS is currently in prototype stage. Over recent weeks IAT21 have conducted extensive constrained flight tests in a specially prepared laboratory near Salzburg, including the transition from vertical to forward flight, and are now ready to move to an open test range for free flight tests. In trials to date D-DALUS has met the performance criteria placed upon it and appears to be scalable, becoming more efficient and less complex as it increases in size. It will therefore be ideally suited for applications that range from maritime search and rescue, through the carriage of freight, to operating alongside and within buildings during fires or, for example, nuclear accidents. D-DALUS next steps IAT21 have now formed a collaborative partnership with Cranfield in the UK to take the aircraft forward to full flight certification. IAT21 are now working on an up-scaled engine, the external hull shape and the integration of next generation guidance and control systems. http://www.d-dalus.at/ Listen to 'Strange Days...
