7.12 Electric System
general
The REMOS
GX
iS
has quite a complex electric system for reliable
support of all electric engine and aircraft systems. It is designed for
maximum reliability and user-friendliness, as there are a lot of vital
electric subsystems installed on the aircraft.
The engine in particular is reliant on electric energy. Following vital
engine subsystems are electrically powered: dual channel injection
and engine management, ignition, fuel pumps, engine instrumenta-
tion.
As the engine imperatively relies on electric power, two generators are
installed. One of them (generator A, nominal power output 220W,
rated current 16A at 14.2V) is responsible for engine subsystems only,
the other one (generator B, nominal power output 420W, rated current
30A at 14.2V) is for the aircraft systems.
After engine start-up, electric power is supplied by generator B, aircraft
systems are powered by the batteries. Once engine speed is set
above 2,500 rpm for at least 5 seconds, the engine switches to gener-
ator A and the aircraft systems are now powered by generator B.
In the unlikely event of a failure of one of the generators, electric power
supply for the engine is ensured. In such an event, the engine is pow-
ered by the intact generator and the aircraft systems run on batteries
only. By activating the
“emergency mode” with the emergency switch,
the aircraft systems are powered with excess power of the remaining
generator and the aircraft batteries.
The aircraft is equipped with two batteries. In case of emergency, both
batteries supply energy exclusively; in normal operation, they provide
surplus energy for peak power consumption. During engine start-up,
one battery supplies power to the engine incl. starter engine and fuel
pumps, the other battery is for the aircraft systems and the avionics.
During start-up, the avionic bus is completely separated from the en-
gine bus. By this, the REMOS
GX
iS
has does not have a dedicated
avionic bus switch, bus selection is completely automatic.
