AIRCRAFT WITH ISOLATED GROUND
First Claim
1. An aircraft with isolated ground which comprises:
- an airframe made of a composite material;
a voltage source mounted on the airframe;
at least one electronic device mounted on the airframe;
a power wire isolated from the airframe and connecting the electronic device to the voltage source;
a circuit breaker interconnected to the power wire; and
a ground wire isolated from the airframe and grounding the electronic device to the voltage source.

Abstract
An aircraft having an airframe made of a composite material is provided with an isolated ground in order to reduce the threat of electrical fires. The aircraft includes a voltage source and at least one electronic device mounted on the airframe. Further, a power wire isolated from the airframe interconnects the voltage source and the electronic device. Also, a ground wire isolated from the airframe interconnects the voltage source and the electronic device. As a result, the onboard electric circuits are isolated from the airframe. In order to reduce electromagnetic interference in the circuit, the aircraft may be provided with a powerside capacitor, to interconnect the power wire and the airframe, and a groundside capacitor, to interconnect the ground wire and the airframe.
