Mini-Bee

We aim to develop through a Lesser Open Source License [1] a hybrid Vertical and Take-Off Landing (VTOL) aircraft for medical purposes.

Project is at TRL4 in 2023.

The Mini-Bee project is an open-source initiative undertaken by Technoplane SAS, where multiple actors including academics, individuals, and industries collaborate to achieve the project's goals. The project is achieved under a dedicated lesser open-source license, which allows for public sharing of project works on a wiki. The project's works are mainly shared on a public wiki, with tasks being achieved with coordinator management.
Private tasks and products covered by other licenses or intellectual property rights can be included within the project, with only interface works being covered by the open-source paragraph of the Lesser Open Source License. Participants may use the works done on the project for technical or commercial use, and standard royalty percentages are defined by default. More information can be found on the Industrial Property and Collaborative Bee websites.

The development of a hybrid VTOL multicopter is an exciting project that is set to revolutionize the way we travel. This innovative aircraft is currently in TRL-4 configuration. The project includes several unique features that set it apart from traditional aircraft designs.

One of the most significant features of this hybrid VTOL multicopter is its propulsion system. It is equipped with a single Rotax 915is engine without gearbox and two Emrax 228 twin hexaphase high-voltage motors that are combined and cooled. This configuration provides the aircraft with an excellent balance of power and efficiency, making it an ideal choice for short-range flights.

In addition to the propulsion system, this aircraft is also equipped with a redressor and a superconductor. These two components work together to regulate the power output of the electric motors and improve the overall efficiency of the aircraft. With sixty electric engines and propellers, the hybrid VTOL multicopter can quickly take off and land vertically, making it an ideal choice for urban transportation.

The aircraft's design also includes several safety features, such as three wheels, two seats, and a parachute. The three wheels provide stability during takeoff and landing, while the two seats offer comfort and safety for the passengers. In the event of an emergency, the parachute can be deployed to ensure a safe landing.

The hybrid VTOL multicopter is also designed to be piloted by two people, further increasing its safety and reliability. The two pilots can work together to ensure that the aircraft is operating correctly and safely, providing peace of mind during their flight.

Overall, the hybrid VTOL multicopter is an innovative and exciting new project that has the potential to transform the way we travel. With its efficient propulsion system, safety features, and piloting capabilities, this aircraft is an excellent choice for short-range flights in suburban areas. As the project continues to develop, it will be interesting to see how it evolves and impacts the future of air transportation.

Minibee TRL2

During 2015 and 2016 multiple universities studied concept and TRL1 closed in June 2016.
In summer 2017, project achieved TRL2 at Paris Air Show 2017 and is now entering TRL3 with more than 15 universities and 10 industrial interested !
In 2018, studiez have made progress on the engine and hybrid configuration.
