New impellers
Because of a defect with one of the impellers, the BWB team bought new trustier and stronger impellers.
They have already succesfully been tested and are expected to be installed until May to be proved with the flying model.
The static thrust for example is now more than twice as large as before. The necessary energy is guaranteed by new accumulators, which have remained completly cool while testing them.
Survey of some technical data:
| • Name: | DS-77-DIA |
| • Static thrust: | 71-91 N |
| • Weight: | 1240 g |
| • Inner diameter: | 120 mm |
| • Rotary speed: | 24.000-28.500 U/min |
| • Power input: | 4,2-6,2 kW |
New Faces, New Vigor!
The AC 20.30 team is pleased to announce that it can welcome eleven new faces in the project. These new students have been waiting for half a year as a contender for their appointment as a full member. During this probationary period they had to prove themselves in many tasks that were entrusted in them.
In this way we wish them good luck and creative energy to help to continue this project foward to a glorious future!
Flying autumn
After the successfully accomplished maiden flight in summer 2011, the BWB team met again at "Hungriger Wolf" airfield to gather analyse data such as GPS, groundspeed and flight control indications with the measurement system inside the AC20.30.

Remodeling of the website (16/10/11)
Now that the AC20.30 has launched its first flight successfully, we are proud to present our new website. We have a new ambitious web project with which we will keep you up to date. Particularly in the media/download area we will provide you with more information about our project in future.
Successful maiden flight (09/04/11)
After more than two years of construction time and a subsequent period of one year for completing all on-board systems, on May 7th the time had come: The new flying 1:30 scale model of the Blended Wing Body AC20.30 took off for its maiden flight at Hungriger Wolf airfield near Itzehoe / Germany at 01:30 pm. The press also attended this event (see picture, text in German) and observed eagerly, as did all the students from the research team. This new, advanced and more reliable test carrier will allow measuring flights in order to assess the aerodynamic quality of the AC20.30´s shape. It will also be possible to integrate a sophisticated camera system which will turn and look in any direction independently from the model´s heading.
