Festo AirJelly - the flying jellyfish - now more information in English

© Festo

On Tuesday we reported about the amazing AirJelly the jellyfish that gracefully flies through the air. Unfortunately there wasn't much information in English available. But that has changed now. We found the press release by Festo which you can access here or read the piece about the AirJelly right here and the fulyl release on Scribd. You can also go directly to Festo and get high resolution press pictures of the AirJelly here. Also check out the Video of the AirJelly on YouTube.

Air is the element of the AirJelly. Rather than swimming through water like the AquaJelly, it glides through the air with the aid of its central electric drive and an intelligent, adaptive mechanical system. The remote-controlled AirJelly is kept in the air by its helium-filled ballonet.

The AirJelly’s only energy source are two lithium-ion-polymer batteries, to which the central electric drive is attached. This transmits its power to a bevel gear and then to eight spur gears, which drive the eight tentacles of the jellyfish via their respective cranks. The structure of each tentacle is based on the Fin Ray Effect®. Using a peristaltic movement to drive a balloon was previously unknown in the history of aviation. The AirJelly is the first indoor flying object to use such a peristaltic propulsion system. The jellyfish glides gently through the air thanks to this new drive concept based on the reaction thrust principle.

The AirJelly steers through three-dimensional environments by shifting its weight. Its two servo motors are located at the “North pole” of the jellyfish and controlled proportionally. If the pendulum moves in one direction, the AirJelly’s centre of gravity shifts in this direction – the AirJelly is thus able to swim in any spatial direction. The propulsive force of the drive can be varied by moving the Fin Ray® tentacles more quickly or slowly.

Festo demonstrates with this exhibit that a central electric drive – combined with an intelligent mechanical system – can offer fascinating possibilities for “lighter-than-air” aviation. Festo aims to delight its customers with innovative, fascinating and intelligent solutions in both automation and didactics. It therefore offers a wide range of electric, pneumatic and hybrid drive systems, together with the respective sensors and control possibilities.

The Voyager Airship by 21st Century Airships

21st Century Airships a Canadian Airship Development Company, is currently working on a new airship. Up until now 21st Century Airships has been famous for their spherical Airships. They also successfully licenced their technology to the US company Cyber Defense Systems. To see pictures and even a video of their original airship you can also check out a post on the Blog crashworks.
Now 21st Century Airships is working on a new Airship for tourism and sightseeing activities. On their website you can see some great pictures of the gondola which will accommodate up to 19 passengers. Of course such a new development needs a prototype. So 21st Century Airships has build a small scale 2 person prototype of the Voyager Airship which has already complete it's first test flights. Here are the recent announcement released by 21st Century Airships:

September 24, 2007
We have just completed the test flights for the scale version of the Voyager Airship. The Voyager Airship is a 19-passenger craft, purpose designed for sightseeing rides. As expected, the airship was extremely maneuverable and is able to perform VTOL (Vertical Take-Off and Landings). Steering and altitude controls are activated with a joystick, making the pilot's workload very light.

August 1,2007
Our latest airship is now ready to take flight. This distinctive looking airship is a two-seater, scaled-down version of our 19-passenger, sightseeing airship. It will act as a test platform for the many systems, with new and advanced standards, that we are incorporating into our airships.

Although this elongated-shaped airship has stabilizing fins, there are no moving surfaces such as rudders and elevators. Steering and altitude controls are affected by directed thrust from the engines, a system developed and patented by 21st Century Airships Inc. The main advantage of this new system is that it allows the airship to be highly manoeuverable at any speed from 0 to full. This airship has no elevator wheel or rudder pedals. Instead it is simply controlled with a joy-stick.

Test flights are scheduled to begin mid August 2007 near Newmarket, Ontario, Canada. After the initial test flights are completed, the airship will be used for demonstrations, as well as for collecting data for the ongoing Type Certification of our 19-passenger, sightseeing airship.

We quoted the two announcements here since we do not know how long they will stay up on the Website of 21st Century Airships. But make sure to check out the original website for more pictures of the prototype.
The Winnipeg Free Press article we talked about yesterday also mentions that 21st Century Airships is planning on flying the prototype to Winnipeg this coming fall. You can be sure we will be reporting about it when it happens.

Zeppelin NT articles

In addition to our coverage about the damage of the Zeppelin NT prototype we would like to point out some more resources like all our other Zeppelin articles that you can read to catch up with what has been going on with the Zeppelin lately. Also our Russian friends from Aerocrat have released and Article about the Zeppelin NT prototype incident of course as always in Russian, so check the auto translated Versions by Worldlingo and Google.
In addition to the current coverage about Zeppelin we found a few more sources. Aviation Photos has a collection of very nice Zeppelin pictures. Lycoming the manufacturer of the Zeppelins engines has a featured article called: The Zeppelin NT 07 - A Legend Redefined talking about the many advantages the Zeppelin NT has and the versatility it gets from it's engines. And last but not least we have a Paper written by the Team of the Zeppelin NT Mission in Africa, David Hatch, Stefan Kuna and Jürgen Fecher. The paper is titled: Evaluation of an Airship Platform for Airborne Gravity Gradiometry and talks about the technology and advantages the Zeppelin NT had as an Airborne Platform.
