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. |
