Amazing projects of Soviet and American passenger catamaran aircraft.

In the era of detente and friendship between the USSR and the USA, in 1971, two wonderful projects by Professor George Pokrovsky were published in the Soviet magazine TM. Taking off passenger planes - catamarans. The professor explained this form of the project in terms of aerodynamics: shock waves of wings. See diagrams in the illustration below. When the professor died in 1979, after, in 1983, during the time of President Andropov, this magazine TM published the second version of the catamaran aircraft. On the cover is a colossal passenger flying trimaran, triple TU-144. Inside the journal - a scientific article about the projects of ultra-giant aircraft. In 2011, on the Internet, I found American analogues of our projects: a passenger aircraft catamaran based on Concord in the Popular Mechanics magazine 1984, and early designs of the American supersonic twin-fuselage liner 1971, also Popular Mechanics.

I searched further and was very surprised. In America, real flying catamarans were created in 1940-2021, and a lot, especially Paul Allen's flying spaceport. In 2022, a flying private light catamaran aircraft with a propeller engine was created in the USA.

In the USSR, real catamaran aircraft have never been built.
