The Pais patents are a group of unusual U.S. patents filed on behalf of the U.S. Navy by aerospace engineer Salvatore Pais, the best known being for a "craft using an inertial mass reduction device". The press dubbed them the Navy's "UFO patents".[1][2]
The craft patent
Pais, an engineer at the Naval Air Warfare Center Aircraft Division at Patuxent River, Maryland, filed the application on 28 April 2016; it was published on 2 November 2017 and granted as U.S. Patent 10,144,532 on 4 December 2018. It describes a hybrid aerospace-undersea craft that could be shaped as a cone or a triangular delta wing. Microwave emitters inside a resonant cavity between a charged outer wall and an insulated inner wall would vibrate the outer wall rapidly, which the patent claims would polarise the vacuum around the craft and reduce its inertial mass.[1]
Getting it granted
The patent examiner at first rejected the application as implausible. It was granted after James Sheehy, chief technical officer of Naval Aviation Enterprise, wrote that the invention was operable and warned that China was already investing in similar technologies.[2][3]
Other patents
Pais also filed applications for a high-frequency gravitational wave generator, a compact "plasma compression" fusion reactor, a room-temperature superconductor and an electromagnetic field generator to deflect asteroids. All rest on what he calls the "Pais effect", in which electrically charged matter vibrated or spun at high speed would create extremely intense electromagnetic fields.[3]
Tests and results
The patents drew wide media attention. Records obtained by The War Zone showed that the Navy tested the Pais effect from October 2016 to September 2019 at a cost of about $508,000 and could not demonstrate it; physicists consulted by the publication said the ideas had no scientific basis. The testimony compares the craft patent with concepts in AAWSAP's reports and with NASA's 2014 tests of the "Cannae drive", which reported tiny thrust later attributed to errors.[2][3][4]
