AIRPLANE DESCRIPTION
7.6.8 PROPELLER
VELIS Electro is equipped with the 3-blade, fixed pitch Pipistrel P-812-164-
F3A propeller. Its diameter is 1640 mm. The blades are made from carbon
fiber composite material and stainless steel. The blade root and propeller
hub are machined aluminum parts.
7.7 ELECTRICAL SYSTEM
7.7.1 ELECTRICAL SYSTEM
The airplane is equipped with a high and low voltage system. The high volt-
age electrical system, powered by the two high voltage batteries, is used for
propulsion (see section 7.6.2 High voltage battery system). The low voltage
battery system is used to power avionics and system controllers on the air-
craft. Low voltage power is generated from high voltage batteries by a DC/
DC converter. An auxiliary 12V battery is also present, installed on the cabin
bulkhead behind the switch panel.
A junction box, installed in the engine compartment, houses the DC/DC con-
verter, charging relays and fuses, and merges the high voltage cables from
the batteries, charging port and power controller.
7.7.2 LOW VOLTAGE POWER GENERATION
The avionics electrical system is a 12-14 V DC system. Power is supplied
through a DC/DC converter that converts the 345 V DC from the high volt-
age batteries to the 14 Volt for the avionics and for recharging the auxiliary
battery (13.2V, 12,4 Ah). The DC/DC converter is located in the junction box,
in the engine compartment of the aircraft. In case of emergency and loss of
