US unveils concept for unique X-65 experimental aircraft with active flow control

The US Department of Defense Advanced Research Projects Agency (DARPA) has unveiled a unique aircraft. It is called X-65 and so far exists only in the form of a concept.

Here's What We Know

The experimental aircraft does not have traditional external flight controls. In simple terms, it has no tail rudders or flaps. The aircraft manoeuvres by controlling the airflow around it.

The aircraft will be developed as part of the Control of Revolutionary Aircraft with Novel Effecters (CRANE) programme. The aim of the project is precisely to create an experimental unmanned aerial vehicle that will be able to control the airflow around it. The technology is called Active Flow Control.

The American specialists believe that active airflow management will improve aircraft performance by eliminating the components that increase weight and make the structure more complex. The technology will ensure stability and control in flight.

The groundbreaking X-65 will include so called "modular wing configurations". With these, DARPA developers will be able to integrate advanced technology for flight tests. The tests are expected to start in three years.
