BlackFly's strange-looking, yet practical design arouses the curiosity and skepticism of many at first glance. This aircraft's particular design simplicity is the key to make it affordable, robust, safe, and convenient for mass adoption. In this video, I will explore the three characteristics, that in my opinion, make Opener's Black Fly design truly innovative and potentially disruptive.

I hope you enjoy it!

The design of e-VTOL aircraft is driven by five degrees of freedom. Payload, Speed, Range, Noise, and Simplicity. These degrees of freedom are strongly interlinked and the improvement of one parameter often disadvantages one or more of the others.

The three most common categories of e-VTOL are:

Multicopter architecture:

Lift and cruise architecture:

Tilt rotor architecture:

However, one of the big downsides of a Tilt-body architecture is the varying positioning of the operator, along with the aircraft, during the different stages of the flight.

The landing gear consists of a rub-strip on the bottom of an amphibious hull and a small rubber bumper on the rear of the fuselage. The lower edge of the winglets are skids that limit the vehicle's roll when parked.

A custom vehicle cart is provided with each BlackFly. The cart allows a single individual to easily move a BlackFly over unfinished surfaces.

In order for BlackFly to become mass adopted, I think, Opener will have to improve the noise emission of its aircraft. The high tip speed of the blades is the main generator of noise in eVTOL aircraft. The BlackFly features a Tilt-Body architecture, this gives Opener an extra degree of freedom when designing the propellers.
