Aircraft rotary wing

In the history of aviation a lot of aircraft that do not find their application in a large aircraft and over time been forgotten. However, this does not necessarily mean that the concept of these aircraft were wrong or their performance proved unsatisfactory. To this category can be attributed to devices having a wing shape close to round. They were created and built a very small amount, and the scheme is studied not as deep. However, these aircraft in the tests were shown some performance characteristics that exceed such characteristics as aircraft usual scheme.
