Circular winged
.jpg)
Rotary wing aircraft are tailless aircraft with an extremely low aspect ratio and an approximately circular wing plan . Orbiting wings that have a concentric ring section, such as the Lee-Richards Annular Monoplane , are also counted among the circular wingings. Designs with a straight front wing edge and a semicircular floor plan also belong to this category. This type of aircraft had the peak of its popularity in the 1930s and 1940s; modern designs based on this concept are not known. The Australian David Rowe built a small circular plane called UFO (= Useless Flying Object) and is demonstrating it at flight days. Since 2015 it has also had a retractable landing gear, which reinforces the impression of a UFO .
Gyroscopic aircraft belong to the extremely low aspect ratio aircraft .
