Stemme S10

The Stemme S10 motor glider is a German manufacturer Stemme.

History

The prototype of the Stemme S10 was launched in 1986 in Braunschweig for its first flight in 1987 and presented at the AERO in Friedrichshafen in its final form for the first time. In 1990, the Type Certificate was issued and delivered the first production version. In 1994, the S10- V with variable pitch their type certification. In 1999, the Mountain Wave Project ( MWP ) used a Stemme S10- VT for their first research expedition in the Andes. In addition to numerous measurement flights a first record flight to Tierra del Fuego ( 1546 km ) succeeded. In the following years could be achieved in cross country flying with the machine more world records. The highlight was a flight on 26 November 2000, when Klaus Ohlmann in 14 hours back put a free series on three turning points of 2,463 kilometers. In a second MWP measurement campaign in 2006 come with a completely equipped for research platform S10- VT ( BATprobe ) over the Tupungato region Anconcagua first scientific turbulence measurements over the Andes to 12,500 m.

By March 2007, about 200 of these machines were produced in different variants.

Construction

The aircraft is a single-engine two-seat high-wing monoplane, whose wings are equipped with flaps and executed foldable. The pilots are side by side under accommodated. The main landing gear is electrically retractable.

The propeller folds up when not in use under the nose fairing also Propellerdom mentioned together, which is designed in the longitudinal direction and so freigiebt a circumferential gap for the propeller or closes. The propeller is driven via a remote shaft and a reduction gear of an internal combustion engine installed behind the cockpit.

Variants

In addition to the original model S10, there was the variant Stemme S10- V with a variable pitch propeller. These models were driven by the Limbach engine. The current top model, the Stemme S10- VT is equipped with a variable pitch propeller and a turbocharger engine from Rotax since 1998. The Stemme S10- VTX is an aerial work aircraft based on the S10- VT with an increased allowable takeoff weight of 980 kg, which is equipped for research and test flights with external pods on the lower wing. The external load container can be equipped as required with a maximum of 60 kg sensors or other test equipment on each side.

At ILA 2000 for the first time Stemme S15 was presented, which differs from the S10 only by a higher load capacity, higher maximum take-off mass (980 kg) and for reinforced and provided with three-piece wing flaps. Based on the S15 Stemme offers the unmanned reconnaissance aircraft Sagem Patroller with a 85 kW motor Rotax 914F. The development of this began in October 2008 and was carried out during the year 2009, the first flight. It has a triple redundant flight control system, a camera system Euroflir -410 and corresponding communication equipment for transmission of data on up to 400 km in real time.
