“Electric Aircraft”
Philosophy (Cont.)
Airframe electrical systems can be switched on and off as
needed, resulting with “consequential effects”, thus
conserving power. Adoption technologies of generation and
distribution of variable voltage variable frequency (VVVF)
would increase mass savings.
The VVVF system power output varies with engine/generator
rotational speed. The generators are designed to supply
constant voltage to frequency ratio, thus improving the
performance of electric motors and eliminating the need to
use controllers.
