Dean drive

The Dean drive is a type of reactionless drive proposed by inventor Norman L. Dean in the 1950s and 1960s. The device was claimed to produce unidirectional thrust without expelling any mass, which would violate the law of conservation of momentum and Newton's third law of motion. Despite its controversial nature, the Dean drive has been a subject of interest in the field of fringe science and alternative propulsion systems.

History[edit | edit source]

Norman L. Dean, an American inventor, first introduced the concept of the Dean drive in the late 1950s. Dean claimed that his device could generate thrust by using a system of rotating and oscillating masses. He demonstrated his invention to various audiences, including members of the American Rocket Society, but his claims were met with skepticism by the scientific community.

Mechanism[edit | edit source]

The exact mechanism of the Dean drive remains unclear, as Dean did not fully disclose the inner workings of his device. However, it is generally understood that the drive involved a combination of rotating and oscillating masses that purportedly created a net force in one direction. Critics argue that any observed motion was likely due to frictional effects or other external influences rather than a genuine reactionless force.

Scientific Reception[edit | edit source]

The scientific community has largely dismissed the Dean drive as a perpetual motion machine and a violation of fundamental physical laws. Experiments conducted by independent researchers have failed to replicate Dean's results under controlled conditions. The consensus is that the Dean drive does not produce a true reactionless thrust and that any observed effects can be attributed to experimental errors or misinterpretations.

Legacy[edit | edit source]

Despite its lack of scientific validation, the Dean drive has inspired interest in alternative propulsion concepts and has been referenced in science fiction literature. It remains a topic of discussion among enthusiasts of unconventional technology and fringe science.
