The aileron doubles as a full span flap. |
![]() |
The spoilers at the inner wing are located optimally to avoid inducing a pitching moment. |
![]() |
The integrated hinge is a technical treat. |
![]() |
The hinge axle runs over the whole control surface length in aluminum tubes which are wrapped up in the sheeting carbon fibre. |
![]() |
This results in a gapless hinge... |
![]() |
... and thus high control surface efficiency. |
![]() |
All joints and connections are designed for form fit. |
![]() |
The electrical connections for the propulsion units engage automatically when mounting the tail surfaces to the fuselage. |
![]() |
The propulsion motors are integrated into the stabilizer tips and mounted in two ring structures each. |
![]() |
The propulsion units are acoustically de-coupled from the airplane structure by silent blocks. Also, there are sensors for measuring the propeller thrust in flight. |

The solar cell interconnections are a new development too: ... |
![]() |
... SMT soldering paste is applied in a silk screen process, then the cell connectors are soldered in place by a special machine. |
![]() |
Extremely thin silver strings are used.to connect the solar cell top surfaces. Together with an elaborated soldering technique, only very little thickness is added to the cell assembly. |
![]() |
This is a prerequisite for filling the solar generator top surface flat and even with very little resin. |
