Abstract

A field configurable autonomous vehicle includes modular elements and attachable components. The vehicle can be assembled from these modular elements and components to meet desired mission and performance characteristics without the need to purchase specially designed vehicles for each mission. The vehicle can include a modular propulsion system with magnetic drive.

First claim

What is claimed is:

1. A method for providing propulsion to a vehicle, comprising the steps of:
locating a first diametrically magnetized magnet having both a first polarity and an opposite polarity in an interior volume of a propulsion module;
locating a second diametrically magnetized magnet having both the first polarity and the opposite polarity in a propeller assembly, the first and second diametrically magnetized magnets attract when the magnets are stationary;
coupling a propeller to the second magnet;
rotating the first magnet; and,
rotating the second magnet in response to the rotation of the first magnet whereby the propeller rotates.

2. The method of claim 1 , wherein the step of rotating the first magnet further comprises coupling the first diametrically magnetized magnet to a dc motor.

3. The method of claim 1 , wherein the step of coupling the propeller to the second magnet further comprises coupling a counter rotating propeller.

4. The method of claim 1 , wherein the step of locating the first magnet further comprises providing an air gap between an exterior wall of the propulsion module and the first magnet.

5. The method of claim 1 , wherein the step of locating the second magnet further comprises providing an air gap between an exterior wall of the propeller assembly and the second magnet.

6. The method of claim 1 , wherein the propeller is formed by additive manufacturing.

7. The method of claim 1 , wherein the propulsion module is formed by additive manufacturing.
