Navar Falcon high-performance transformer passenger hybrid-electric VTOL concept design aircraft
The Navar Falcon is a futuristic high-performance long-range transformer passenger hybrid-electric VTOL concept design aircraft. The aircraft was designed from the beginning for high-speed air travel, agility, precision maneuverability and long-range flying. The aircraft has also been designed to provide an incredible amount of fun for the pilot and passenger.

The aircraft has a canopy over the cockpit providing excellent views for the pilot and passenger. The interior is modern and the seats are both very comfortable and ergonomic in design. Taking a closer look at the front of the aircraft, there are three steps for entry and exit of the cockpit. The aircraft also has room for luggage for both the pilot and passenger.

The aircraft has a unique forward swept wing with winglets design that in addition has a transformer feature. The ends of the main wing fold down and can be used for additional aerodynamic performance and when landing, the wings fold down and ends of the wing have landing struts on the bottom of the folded wing. The rear tail has two forward angled vertical stabilizers and when the aircraft lands, the vertical stabilizer assembly folds down and acts as the rear landing gear.

The aircraft has three advanced high-performance electric ducted fans-in-wing, uses nine electric motors and uses a hybrid-electric power source. If you notice in the picture above, it shows the advanced electric ducted fans which have multiple blades (or propellers). For forward flight, there is a turbine engine in the rear of the aircraft. The aircraft uses a hybrid-electric power source to provide the needed speed and range for advanced air mobility. When hydrogen-fuel cell and solid state batteries mature, the aircraft will be fitted with this technology. The fuselage is made from carbon fiber composite material for a high strength and low weight ratio.

Specifications:

  • Aircraft type: Long-range high-performance hybrid-electric VTOL passenger concept design aircraft
  • Piloting: 1 pilot (in the future, remote or autonomous piloting)
  • Capacity: 1 passenger and luggage (With remote or autonomous piloting, 2 passengers and their luggage)
  • Cruise speed: High-speed
  • Range: Long range
  • Propellers: 3 advanced high-performance electric-duct-fan in wing
  • Electric motors: 9 electric motors
  • Power source: Hybrid-electric power source (in the future, hydrogen fuel cells or batteries)
  • Fuselage: Carbon fiber composite
  • Window: Canopy over cockpit
  • Wings: 1 main transformers wing with winglets
  • Tail: 2 angled and swept forward vertical stabilizers
  • Landing gear: Retractable tricycle landing gear. The outer portion of the main wing folds up and then inward and part of the wing becomes the forward landing gear. The rear vertical stabilizers angle down and become the rear landing leg.
  • Safety features: Distributed Electric Propulsion (DEP), provides safety through redundancy for its passengers and/or cargo. DEP means having multiple propellers (or ducted fans) and motors on the aircraft so if one or more propellers (ducted fans) or motors fail, the other working propellers (or ducted fans) and motors can safely land the aircraft. There are also redundancies of critical components in the sub-systems of the aircraft.
