TRL2 started in 2013. It was planned to have a 3 years duration. Project are being launched for academic year 2014/2015<BR>
 +
But in 2015, we launched Mini-Bee project and for 5 years, all energy was taken by this new project.<BR>
 +
In 2021/22 two new projects were made by Estaca Engineering University in France. Project is now able to finish TRL2.

While the project made significant strides in technology and innovation, it faced challenges in aligning focus. The Mini-Bee project drained resources and energy for a prolonged period. However, with renewed vigor and academic partnerships, the project aims to complete TRL3 successfully.
 +
 
 +
Conclusion
 +
The Bee-Plane project, transitioning from TRL2 to TRL3, showcases an extraordinary commitment to innovation, academic involvement, and practical applicability. With its unique design changes and extensive studies, it stands as a testament to the future of modular and adaptable aerospace technology.
 +
 
 +
== Technological Advancements and Upcoming Milestones ==
 +
 
 +
In line with the framework set by the Lesser Open Bee License 1.3, we are excited to unveil the next set of technological advancements for the Bee-Plane. The R&D team at Estaca Engineering University has successfully addressed the weight distribution issues for TRL3, reducing the overall weight by 15%. A cutting-edge battery technology, currently under patent review, is expected to improve energy density by 20%.
 +
 
 +
Upcoming milestones include the finalization of our dynamic stability tests by Q2 2024. Also, collaboration with Ecole Centrale Paris on AI-based autonomous piloting is set to commence, aiming for full autonomy by TRL4.
 +
 
 +
Note that access to all raw data, simulation results, and software code is available upon request, strictly adhering to the open-source clause of the Lesser Open Bee License 1-3.

Project history

TRL2 started in 2013. It was planned to have a 3 years duration. Project are being launched for academic year 2014/2015
But in 2015, we launched Mini-Bee project and for 5 years, all energy was taken by this new project.
In 2021/22 two new projects were made by Estaca Engineering University in France. Project is now able to finish TRL2.



TRL3 Guidelines

Basket (detachable fuselage)

  • Basket is design to be optimum for passengers frequent flight, then it is adapted to other usage (fret, hospitals...)
  • Basket with three pressure bubbles, Internal structure adapted to 3-4-3 seats configuration
  • Central luguage area for passenger basket (220 PAX full eco, 200 PAX in 2 classes), Only 1 central large main door for passengers on each side.
  • Basket with APU on the back, 2 electric directional wheels, additional fuel tanks in the basket.
  • Bee-Plane Passenger Floor Plan
  • Hospital basket

    Bee (upper aircraft)

    Bee-Plane: The Evolution from TRL2 to TRL3

    A Milestone of Innovation: TRL3 Guidelines At TRL3, the Bee-Plane demonstrated several advancements over the TRL2 design:

    Basket Design: The fuselage, or the "Basket," introduced an optimized internal structure for frequent passenger flights, adapted for other use-cases like cargo and hospital transport.

    Engine Configuration: A significant change was the engine layout. Now four PWC 150A turbopropellers are positioned below the main wings, along with a central turbofan at the back.

    Key Contributions to Aerospace Engineering The Bee-Plane's unique structure posed new possibilities and challenges:

    Bi-taildragger Configuration: The landing gear setup is designed to optimize space and weight, enabling a more versatile aircraft.

    Main Landing Gear: The placement behind the cockpit adds stability and flexibility in rough landing scenarios.

    Partnerships and Academic Contribution The project has had a slew of academic partnerships, involving universities like Estaca, Ecole Centrale Paris, and SupMeca. Each has contributed specialized research and developments:

    Mechanical and Aerodynamical Studies: Different iterations of landing gear, cabin layouts, and energy management have been developed by academic partners, predominantly Estaca.

    Certification Studies: Progress was made on compliance with Part 21 and Part 145, essential for aircraft design and maintenance regulations.

    Comparing TRL2 and TRL3 Guidelines The advancements from TRL2 to TRL3 were incremental but vital:

    Basket Flexibility: At TRL2, the Basket had a 3-3-3 seat configuration, while TRL3 saw a shift to 3-4-3 seats.

    Engine Changes: The number of turbopropellers increased from two to four, enhancing power and stability.

    Economical Studies Economic impact studies were conducted, with SupMeca focusing on how Bee-Plane could affect airline economics. The model suggests that Bee-Plane's modular approach would allow cost-effective solutions for airlines.

    Challenges and The Way Forward While the project made significant strides in technology and innovation, it faced challenges in aligning focus. The Mini-Bee project drained resources and energy for a prolonged period. However, with renewed vigor and academic partnerships, the project aims to complete TRL3 successfully.

    Conclusion The Bee-Plane project, transitioning from TRL2 to TRL3, showcases an extraordinary commitment to innovation, academic involvement, and practical applicability. With its unique design changes and extensive studies, it stands as a testament to the future of modular and adaptable aerospace technology.

    Technological Advancements and Upcoming Milestones

    In line with the framework set by the Lesser Open Bee License 1.3, we are excited to unveil the next set of technological advancements for the Bee-Plane. The R&D team at Estaca Engineering University has successfully addressed the weight distribution issues for TRL3, reducing the overall weight by 15%. A cutting-edge battery technology, currently under patent review, is expected to improve energy density by 20%.

    Upcoming milestones include the finalization of our dynamic stability tests by Q2 2024. Also, collaboration with Ecole Centrale Paris on AI-based autonomous piloting is set to commence, aiming for full autonomy by TRL4.

    Note that access to all raw data, simulation results, and software code is available upon request, strictly adhering to the open-source clause of the Lesser Open Bee License 1-3.
