Advanced Reconfigurable VTOL Aircraft - ARVA

Description
ARVA represents a new vertical lift (VTOL) aircraft concept with a configuration that is seif, quiet and efficient.

ARVA uses Distributed Electric Propulsion - DEP as a rotorless drag-reducing propulsion system and can be deployed in a versatile hover-capable flying aircraft to lift heavy loads efficiently. Scalable with a combination of stable overlapping flight roles and modes from horizontal take-off through assisted low speed and stationary hover through to high speed winged flight and back. ARVA mainly employs a multiple ducted fan arrangement and new ducted fan configuration creating a very efficient air distribution. The innovative ducted fans are used for vertical lift and also for horizontal propulsion. The ducted fans are grouped in three multiple propellers or powerplants, two of them being located in the front of the fuselage and the third at the rear side located between two struts fixed on the fuselage. ARVA uses two sets of fixing wings and one set of mobile wings. As an unmanned system or as autonomous / piloted VTOL system, this application offers increased operational versatility, stability, scalability, maneuverability, energy efficiency, load capacity, performance, low noise and increased safety potential. Other advantages include the simplified mechanical construction over helicopters with a series of multiple redundant electric motors with independent adjustment for directional thrust. Blade destruction will not cause catastrophic power loss from the multiple motors. ARVA offers reduced footprint and consequently low safety issues when operate in city or other similar environments. When compared with the concurrent solutions (Aurora X-VTOL and Lilium) ARVA can retract its wings and can be operated and parked in reduced areas. In emergency cases ARVA can glide using its normal wings not affected by the ducted fan location, increasing even more the redundancy. ARVA is a scalable concept and can be reproduced from small UAVs to large or very large aircraft.
