Lenticular Craft Propulsion Types Overview (or a combination of which)
1950-1954; Project Magnet

1952 - Rene Couzinet, Couzinet RC-360 "Aerodyne"
url: https://ufologie.patrickgross.org/aircraft/couzinet.htmA vertical takeoff aircraft (VTOL) that used two contra-rotating discs powered by three engines. A second model was designed with six Lycoming engines (180 hp each) and one Marcel Dassault Viper turbojet.
1954 Avro Project Silverbug; 1959 Avrocar

1967-1980s - Moller M200G Volantor

1974 - Skyship Flying Saucer, Lenticular Airships, Buoyant Flying Saucers

1974-1980s - Lightcraft
