Could there really be a new form of propulsion that challenges the way we look at transportation?
DENVER, Nov. 13, 2009 — Many have tried to develop new and unique forms of propulsion over the past 100 years and virtually all have been disproven. In 2006, however, Aries Propulsion Research Labs (APR Labs) introduced a new method of propulsion technology labeled Omni-Directional Propulsion (“ODP”). The method was created by designer Chris B. Hewatt and was first published on the United States Patent and Trade Organization (USPTO) Web site as publication 20060230847. Since its publication, this unique design has been gaining attention in the transportation industry, but could have its greatest impact on the marine industry because it creates movement without propellers. Removing the propellers from the water would result in a virtually noiseless technology eliminating considerable drag from the drivetrain while at the same time increasing efficiency. The concept is green in nature because it eliminates most of the drivetrain components in just about every vehicle seen in transportation today.
The design is simple and uses similar technology to what is used to make attitude adjustments in the space shuttle. The space shuttle uses Control Moment Gyros (CMG) torque to position itself, but the CMG has a very limited range of movement and creates no forward thrust. Maintaining forward thrust is impossible because the shuttle’s CMGs are fixed throughout the hull. ODP allows the CMG to freely rotate 360 degrees around the body of its host vehicle in a constant motion. As the CMG rotates around the vehicle, a locking mechanism is engaged and disengaged at the same degree of rotation and torque is produced opposite that of the rotating CMG. When this happens, torque is transmitted down to the host vehicle and forward movement occurs. Detailed images and animations of the working concept can be found at http://www.aprlabs.com under the “animations” link.
In 2009, APR Labs began testing ODP for efficiency and thrust using Computer-Aided Design (CAD). During testing, the single-shaft CMG design had problems with eccentric imbalancing that was solved by creating a two-shaft, four-shaft, and an eight-shaft design. To assist with design validation, APR Labs hired Prairie West LLC in Boise, Idaho to test the model and to gauge potential efficiency and forces produced by ODP. Prairie West used a combination of Solidworks 3D CAD and Simulation software to test the design and to create detailed reports of potential forces produced. These reports can be found at http://www.aprlabs.com under the “reports” link.
The site also includes graphic images and a photograph of the first prototype. The goal of APR Labs is to gain recognition of this new technology so more companies can get involved in testing and hopefully prove the theory.
