Ultra-Long Range. 

Folding Wings in Hover Mode

The moment of inertia is significantly reduced on the roll axis, improving the safety of the hover system and reducing vertiport footprint.

Propeller Drag Eliminator

Retractable pontoons cover the propellers to reduce drag coefficient in forward flight, increasing energy efficiency.

High Efficiency

Lifting body aircraft design provides the ideal long range efficiency by utilizing the entire surface area of the aircraft.

Inverted Tail

4x retractable landing gear with wheels provide full ground taxi capability on smooth surfaces.

Pontoons Retracted

With Pontoons in full retract position, the propellers are able to freely operate and achieve a stable hover for the aircraft.

Pontoons Deployed

To minimize drag in forward flight caused by the VTOL system, the pontoons deploy after transition into full forward flight.

Improving Roll Axis Control Authority

 

By folding the wings vertically during hover, the moment of inertia (and the drag holding back roll) is almost eliminated – resulting in less load on the VTOL system, improved power efficiency in hover mode, as well as reduced ground effects affecting safe landing.

Aura Aerospace has developed and tested multiple novel concepts integrating the long range benefits of ballistic wings with the potential benefits of EVTOL aircraft.

While it is possible to make almost any configuration hover and fly, the design tradeoffs are well known. The resulting capabilities of EVTOL aircraft are in fact vastly inferior to executive helicopter services and private jets in service today.

If this new technology is so great, how can that be the case? 

It is not as simple as battery performance, we know that will improve over time. The reason is that the first generation of proposed designs failed to incorporate the many core lessons learned from over a century of fixed wing flight;

  • Streamline aerodynamics (no unused propellers creating drag)
  • Correct centre of mass positioning (no motors on wing tips creating pendulum effects)
  • High thrust jet velocity (delivers high speed)

Within the now wide landscape of EVTOL aircraft concepts proposed, the Ultra-Long range segment is yet to be properly addressed – these design considerations have not been successfully applied in a way that can compete with existing passenger aircraft options today.

The Aura Ranger achieves Ultra-Long Range distances by;

  • EVTOL system completely covered by pontoons in forward flight
  • Center of Mass in line with propulsion on Y axis, eliminating pendulum effects
  • Sustainable Aviation Fuel powered jet engines for high speed cruise 

Ranger
will change global travel.
