Polarstern

The SUMO UAVs were used from on-board the RV Polarstern by the Finnish Meteorological Institute for scientific research in the Weddell Sea/Antarctica. Short report by the Alfred Wegener Institut (in German).

Pegasus

John Cassano from the University of Colorado used the SUMOs on the Pegasus runway near the US Station McMurdo in Antarctica.

Adaptive Control

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

Youtube: UAV with adaptive control: wing drop and engine off on one side

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

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.

Visit to Svalbard

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

Youtube: Micro UAV climbing to 1500m on Spitzbergen/Arctic

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

vertical_profile

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.
