7.2 Electrical system
The electrical power of the jet sustainer system is supplied by
maintenance-free LiFePO type 12-volt batteries. One (or optionally two)
main batteries in the luggage compartment area are fitted with an
additional connector that is plugged into the jet sustainer electrical
system.
A fully charged 10 Ah LiFePO battery is sufficient for 6 extension-start-
retract cycles and 45 minutes of run time. At maximum RPM the system
consumes approximately 5.5 A at 12 V.
The Jet System battery is connected through a bulkhead fitting in the
fuselage center section shelves. The turbine ECU is located in the
center section and all related wiring is distributed throughout the glider
from this point. Wiring looms connect the ECU to the individual system
throughout the glider.
Figure 7-6 illustrates the electrical schematic of the jet sustainer
system.
NOTE:
When the battery is connected to the system a leak current
of 50 mA is drawn by the Jet system, even if the Jet
Master Switch is in the OFF position. Disconnect the
battery from the jet system when not used to prevent
battery drainage.
