Adaptive Control

We tested adaptive control loops that were developed with ENAC and filmed it.

One third of the right wing of a Multiplex Twinstar gets dropped and the right engine is turned off. And the plane keeps flying.

drop_mechanism

The wing was dropped with a special mechanism made of three servos, one pulling and two pushing.

In the Windpark

Together with the Laboratory for Energy Conversion of the ETH Zürich we have adapted their air flow probe to Paparazzi and integrated it into our meteo Funjets. It is used to measure wind vectors/turbulences around wind turbines for a more efficient planning of wind parks. The goal is to understand the impact that a turbine causes to the ones downstream.

Swiss television has an article (in German).

Visit to Svalbard

We flew in the Arctic on Svalbard with the Geophysical Institute of the University of Bergen/Norway.

An on-board video of a vertical climb to 1500m during sunset in Adventalen/Spitzbergen was recorded.

An overall of 91 flights were done in two weeks and we did simultaneous flights with two aircraft over land and sea.

Over the Barents Sea

The scientists from the Geophysical Institute Bergen/Norway flew our Funjets to collect environmental data in the Barents Sea around Spitzbergen, 1300km away from the North Pole.

They took off and landed on the helicopter deck of the icebreaking coast guard vessel KV Svalbard. They got some Paparazzi training before the expedition and operated the UAV on their own, only by the help of a RC safety pilot. They flew in altitudes up to 1500m with ground air temperature of about -20°C and windspeed up to 15m/s.

24th Chaos Communication Congress

We gave a talk at the 24C3 congress in Berlin and presented the Paparazzi project. Two autonomous aircraft flying near Toulouse, France and Hildesheim, Germany were controlled from the big screen in the auditorium in Berlin.

The trajectory was modified in flight, telemetry and live on-board video data was shown. There were teams launching and supervising the aircraft locally. There is an SPIEGEL Online article (in German).

Iceland

We are back from the Icelandic Highlands. It is a harsh environment for both humans and airplanes. The IR sensors performed pretty well and we collected a lot of meteo data for the Flohof campaign in the area around the Hofsjökull glacier.

With the help of the Icelandic ATC we set a new Paparazzi altitude record.

Start


Paparazzi

It all started with a visit to the micro air vehicle contest in Braunschweig EMAV 2004. There was a Multiplex Twinstar and Microjet that flew perfectly even though the weather was not nice at all. They had funny looking sensors that I had never seen on an airplane. It was great to find out that all the used hard and software was open source – Paparazzi. I got in contact with Antoine and Pascal, the fathers of the project. See the main page for the story.
