T T Brown Gravitator High Efficiency Electric Ion Thruster 3D model

If you have always been intrigued by the idea of ion propulsion or gravity manipulation, the Thomas Townsend Brown Gravitator is a must-have. This 3D model, a faithful recreation of one of the world’s most advanced ion thruster designs, is a product of the ingenious work of Thomas Townsend Brown who is famous for his legacy of designing an asymmetrical capacitor thruster, which is a improvement of what has also known as a “lifter” .

With this .stl file get the unique chance to own and test one of the most advanced designs of an ion thruster in real life. This particular ionic lifter has a tri-arcuate top electrode, a spider-like middle electrode designed so that thin wires can be weaved throughout it to form the second terminal, and a small spherical bottom electrode. These are all designed in a way such that the electric field lines are converging and diverging between the respective layers. This allows the device to generate more force due to the acceleration of charged particles in these regions. Thanks to a lot of R & D work by T.T. Brown, we were able to figure out the ideal geometries to maximize the force generating effects.

You can print this gravitator using a conductive material like aluminum or electroplate a plastic print to make it functional as a piece of an electrical circuit. You can also use other dielectrics, such as air or solid materials which would allow higher force and operation in a vacuum if you are advanced tinkerer! Join the growing legion of T.T. Brown enthusiasts, comprising scholars, researchers, technologists, and just the general hobbyists with a passion for the potential of the future of this technology. Buying the Thomas Townsend Brown Gravitator is not just owning another ion propulsion 3D print model; it’s owning a part of American history. Join the countless engineers and scientists who have strived for decades on end to demystify the mechanisms of lifters and gravity itself. It’s a great opportunity to take possession of the concepts that have fascinated the greatest minds in propulsion for nearly half of a century. Promote innovation, science through this simple buy.
