Partnering opportunity

French Technology Transfer Office proposes an innovative unmanned-aircraft vehicle system


A French TTO (Technology Transfer Office) is acting on behalf of an established public laboratory of the Paris region that has developed an innovative system that allows to convert a classic unmanned-aircraft vehicle system (UAVS) into an airplane during the flight. The French public research centre is looking for partners for a technical cooperation or a licensing agreement.

Partner sought

The partner sought could be a company interested in a technological cooperation agreement, or a licensing agreement. The eventual partner should have a clear industrial application in mind, and should have a strong technical background to co-develop the UAVS with the laboratory as the prototype needs improvement.


The French TTO (Technology Transfer Office) is acting on behalf of an established public laboratory of a Paris Region university. A French academic laboratory has developed an innovative system that allows to transform a classic unmanned-aircraft vehicle system (UAVS) into an airplane during the flight. The architecture developed is based on a set of propellers and wings. This new kind of architecture is an hybrid between VTOL UAVS (Vertical Take-Off and Landing UAVS) and airplane-like UAVS. The control of VTOL UAVS is known to be challenging when it switches between hover flight and cruising flight. Indeed, strong and rapid variations of the aerodynamic forces acting on the vehicle can lead to fast and large variations of the angle of attack. *Innovative solution : The new system consists of coplanar propellers and a wing that can rotate around an axis belonging to the propellers' plane. With this design, there is no need of air-velocity measurements to get an efficient control. Moreover, the structure has been designed to be easily scalable as wings can be replaced by different kind of wings without impacting on the rest of the structure. In that way, the UAVS can be tuned according to the conditions of flight, speeds of flight and the embarked payload. * Market Challenges : UAVs can be used in many inspection and surveillance tasks. One of the most promising application is the surveillance of larges structures like electric lines, dams et railroad lines. This surveillance needs high speed to cover large distance and needs the ability to hover when inspecting. * Suggested applications : - Surveillance and security - Inspection of large structures (electric lines, railroad lines) - Aerial photography - Agricultural drones - Geomatics * Partnership : The French TTO is able to provide technical and legal assistance to facilitate the eventual partnership. In case of business potential, the prototype can be partially funded by the TTO. The partner sought could be a company interested in : - a license agreement as the TTO is ready to negociate directly the patents rights for specific applications, or - a technical cooperation agreement as the prototype needs improvment.

Advantages and innovations

innovation : first convertible UAVS (VTOL to airplane) during flight with stability. advantages : - energy efficiency during fast flight thanks to additional wings - flight stability thanks to the articulation at the level of wings allowing to control their frequency. - flexibility for positioning the embarked payload : the proposed structure is based on a quadrotor structure - scalable structure

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
