Abstract

A flight module includes a rotor and a rotor carrier. The rotor carrier includes an elongate, upstanding carriage rail, a carriage supported for movement along the carriage rail, an elongate rotor arm carrying the rotor and supported atop the carriage rail for pivotation, and an elongate strut pivotally mounted between the carriage and the rotor arm. The pivotation includes pivotation between alongside the carriage rail, where the rotor arm retentively carries the rotor in a stowage position, and overhanging the carriage rail, where the rotor arm retentively carries the rotor with a skyward-facing orientation in a flight position. With movement of the carriage along the carriage rail, the strut transfers loading between the carriage and the rotor arm for pivoting the rotor arm between alongside the carriage rail and overhanging the carriage rail, and thereby carrying the rotor on the rotor arm between its stowage position and its flight position.

First claim

What is claimed is:

1. A flight module, comprising:
a rotor, the rotor including elongate blades and operable to generate aerodynamic force by rotating the blades; and
a rotor carrier, the rotor carrier including:
an elongate, upstanding carriage rail;
a carriage supported for movement along the carriage rail;
an elongate rotor arm carrying the rotor and supported atop the carriage rail for pivotation, including pivotation between alongside the carriage rail, where the rotor arm retentively carries the rotor in a stowage position, and overhanging the carriage rail, where the rotor arm retentively carries the rotor with a skyward-facing orientation in a flight position; and
an elongate strut pivotally mounted between the carriage and the rotor arm, wherein pivotation of the strut between the carriage and the rotor arm is imparted with multiple rotational degrees of freedom; whereby

with movement of the carriage along the carriage rail, the strut transfers loading between the carriage and the rotor arm for pivoting the rotor arm between alongside the carriage rail and overhanging the carriage rail, and thereby carrying the rotor on the rotor arm between its stowage position and its flight position.

2. The flight module of claim 1 , wherein the rotor arm is pivotally mounted to the carriage rail.

3. The flight module of claim 1 , wherein in relation to a reference sweep plane through where the rotor arm is supported atop the carriage rail for pivotation, the rotor in its stowage position and the rotor in its flight position, pivotation of the rotor arm between alongside the carriage rail and overhanging the carriage rail is biased for departure away from the reference sweep plane and landing toward the reference sweep plane.

4. The flight module of claim 1 , wherein in relation to a reference sweep plane through where the rotor arm is supported atop the carriage rail for pivotation, the rotor in its stowage position and the rotor in its flight position, pivotation of the rotor arm from alongside the carriage rail to overhanging the carriage rail is biased for outboard departure away from the reference sweep plane and overhead landing toward the reference sweep plane, and pivotation of the rotor arm from overhanging the carriage rail to alongside the carriage rail is biased for overhead departure away from the reference sweep plane and inboard landing toward the reference sweep plane.

5. The flight module of claim 1 , wherein pivotation of the rotor arm between alongside the carriage rail and overhanging the carriage rail is imparted with a single rotational degree of freedom, and with pivotation of the rotor arm between alongside the carriage rail and overhanging the carriage rail, the rotor arm sweeps along a conical surface.

6. The flight module of claim 1 , wherein the rotor arm has a variable length.

7. The flight module of claim 1 , wherein alongside the carriage rail, the rotor arm retentively carries the rotor with an outboard-facing orientation in its stowage position.

8. A flight module, comprising:
rotors, each rotor including elongate blades and operable to generate aerodynamic force by rotating the blades; and
a set of rotor carriers, the set of rotor carriers including:
a shared elongate, upstanding carriage rail;
a shared carriage supported for movement along the carriage rail;
elongate rotor arms, the rotor arms including a rotor arm per rotor, wherein for each rotor arm and rotor, the rotor arm carries the rotor and is supported atop the carriage rail for pivotation, including pivotation between alongside the carriage rail, where the rotor arm retentively carries the rotor in a stowage position, and overhanging the carriage rail, where the rotor arm retentively carries the rotor with a skyward-facing orientation in a flight position, and for at least one rotor arm and rotor, in relation to a reference sweep plane through where the rotor arm is supported atop the carriage rail for pivotation, the rotor in its stowage position and the rotor in its flight position, pivotation of the rotor arm between alongside the carriage rail and overhanging the carriage rail is biased for departure away from the reference sweep plane and landing toward the reference sweep plane; and
elongate struts, the struts including a strut per rotor arm, wherein for each rotor arm and strut, the strut is pivotally mounted between the carriage and the rotor arm; whereby

with movement of the carriage along the carriage rail, the struts transfer loading between the carriage and the rotor arms for pivoting the rotor arms between congregation alongside the carriage rail and branchingly overhanging the carriage rail, and thereby carrying the rotors on the rotor arms between their stowage positions and their flight positions.

9. The flight module of claim 8 , wherein each rotor arm is pivotally mounted to the carriage rail.

10. The flight module of claim 8 , wherein for the at least one rotor arm and rotor pivotation of the rotor arm from alongside the carriage rail to overhanging the carriage rail is biased for outboard departure away from the reference sweep plane and overhead landing toward the reference sweep plane, and pivotation of the rotor arm from overhanging the carriage rail to alongside the carriage rail is biased for overhead departure away from the reference sweep plane and inboard landing toward the reference sweep plane.

11. The flight module of claim 8 , wherein pivotation of each rotor arm between alongside the carriage rail and overhanging the carriage rail is imparted with a single rotational degree of freedom, and for at least one rotor arm and rotor, with pivotation of the rotor arm between alongside the carriage rail and overhanging the carriage rail, the rotor arm sweeps along a conical surface.

12. The flight module of claim 8 , wherein pivotation of each rotor arm between alongside the carriage rail and overhanging the carriage rail is imparted with a single rotational degree of freedom, and for at least one rotor arm, rotor and strut, with pivotation of the rotor arm between alongside the carriage rail and overhanging the carriage rail, the rotor arm sweeps along a conical surface, and pivotation of the strut between the carriage and the rotor arm is imparted with multiple rotational degrees of freedom.

13. The flight module of claim 8 , wherein at least one rotor arm has a variable length.

14. The flight module of claim 8 , wherein for at least one rotor arm and rotor, alongside the carriage rail, the rotor arm retentively carries the rotor with an outboard-facing orientation in its stowage position.

15. A flight module, comprising:
a rotor, the rotor including elongate blades and operable to generate aerodynamic force by rotating the blades;
a rotor arm mount having a rotor arm mount axis and defining a single rotational degree of freedom about the rotor arm mount axis; and
an elongate rotor arm carrying the rotor and pivotally mounted by the rotor arm mount, with the rotor arm non-perpendicular to the rotor arm mount axis, the rotor arm mount directing pivotation of the rotor arm with which the rotor arm sweeps along a conical surface, including pivotation between where the rotor arm retentively carries the rotor in a stowage position and where the rotor arm retentively carries the rotor with a skyward-facing orientation in a flight position.

16. The flight module of claim 15 , further comprising:
an elongate, upstanding carriage rail, the rotor arm pivotally mounted by the rotor arm mount atop the carriage rail for pivotation directed by the rotor arm mount, including pivotation b
