Rotary wing vehicle

摘要

A rotary wing vehicle includes a body structure having an elongated tubular backbone or core, and a counter-rotating coaxial rotor system having rotors with each rotor having a separate motor to drive the rotors about a common rotor axis of rotation. The rotor system is used to move the rotary wing vehicle in directional flight.

主权项

1. A rotary wing aircraft comprising
a first variable pitch rotor blade supported for rotation about a common rotor axis of rotation in a first rotor plane of rotation, a second variable pitch rotor blade supported for rotation about the common rotor axis of rotation in a second rotor plane of rotation, a first blade pitch controller located between the first rotor plane of rotation and the second rotor plane of rotation and configured to control a pitch of the first rotor blade, a second blade pitch controller located between the first rotor plane of rotation and the second rotor plane of rotation and configured to control a pitch of the second rotor blades, a first pitch control linkage having a first end coupled to the first blade pitch controller and a second end coupled to the second blade pitch controller so that displacement of the first pitch control linkage operates both the first blade pitch controller and second blade pitch controller at the same time, and a first servo actuator located between the first rotor plane of rotation and the second rotor plane of rotation and coupled to the first pitch control linkage to operate the first pitch control linkage.
