The Jetoptera Bladeless VTOL, seen in the image above, is a revolutionary aircraft design that utilizes a unique technology to achieve vertical takeoff and landing. This innovative aircraft has a distinct appearance, which can be seen in the picture where it has been resized to 640 pixels and cropped to a ratio of 0.565:1.
The concept of this vehicle is similar to a Dyson fan, as it utilizes air to generate a significant amount of force. It is designed as an air taxi, as seen in this article, with the capability to transport individuals up to 200 miles at a speed of 200 mph.
Jetoptera, a startup focused on propulsion systems, drones, and aerial mobility, is developing a unique aircraft design that utilizes Dyson’s “bladeless fan” concept. This innovative vertical takeoff and landing (VTOL) aircraft has the potential to revolutionize carbon-free travel with its quieter and more efficient operation.
According to the publication New Atlas, the majority of designs for vertical take-off and landing (VTOL) vehicles resemble enlarged drones, featuring large downward-blasting fans to generate upward thrust. In contrast, Jetoptera’s J-2000 takes on a unique appearance, resembling a racing car or Formula One vehicle with rectangular thruster modules. Each thruster is equipped with a bladeless fan system, known as the fluidic propulsion system (FPS), as described by Jetoptera on their technology page.
According to New Atlas, the system is described as follows:
The air is directed onto a wing-shaped surface surrounding the ring, resulting in the creation of negative pressure similar to that which enables aircraft to gain lift. In addition, the phenomenon of fluid entrainment occurs, causing vortices to form at the point where the accelerated air from the cylinder meets the stationary ambient air.
The J-2000 concept is equipped with four active FPS modules for takeoff – two in the front and two in the back. As the aircraft gains altitude, the two front modules can retract into the body, reducing drag. This allows the two rear thrusters to propel the J-2000 at a maximum speed of 200 mph. Jetoptera also has plans for other concepts that can reach speeds of up to 400 mph.
According to Jetoptera, the J-2000 has the potential to be 30% lighter than other VTOL designs that use traditional fans. This significant weight reduction can lead to a fuel efficiency improvement of up to 50%, making it a major contender in the quest to decrease aircraft emissions.
