Helicopter with folding rotor arms
First Claim
1. A rotary wing aircraft apparatus comprising:
- a body;
a plurality of arms extending laterally from the body, and a rotor assembly connected to an outside end of each arm;
wherein the arms are connected to the body such that the arms can be pivoted from a flying position, where the arms extend laterally outward from the body such that the rotor assemblies are spaced in a desired configuration, to a folded position where the arms are positioned substantially parallel and adjacent to each other.

Abstract
A rotary wing aircraft apparatus includes a body and a rotor pair connected to the body by an arm. The rotor pair has an upper rotor driven by an upper motor and rotating about an upper rotor axis and a lower rotor driven by a lower motor and rotating about a lower rotor axis. The upper and lower rotor axes are tilted with respect to each other. Tilting the axes away from the arm increases the distance from the rotor blades to the arm, and decreases the risk of the blades of the rotor contacting the arm. In an aircraft with a plurality of arms extending from the body, and a rotor assembly connected to each arm, the arms can be pivoted from a flying position, where the arms extend laterally outward to a folded position where the arms are positioned substantially parallel and adjacent to each other.
