SIA Aerodium Technologies, 01.11.2022 starts a research project (5.1.1.2.i.0/1/22/A/CFLA/001 ) on the development of the world’s smallest recirculating wind tunnel with a high-quality wind flow and cooling system, which can be installed in amusement parks and shopping centers with limited ceiling height. Support is received from EU funds, the funding allocated by the European Regional Development Fund is EUR 140,000.00.
Aerodium Technologies engineers completed aerodynamic simulations and designed the aerodynamic shape of the R1 recirculating vertical wind tunnel. We utilized our expertise in aerodynamics, fluid mechanics, and computer-aided design to achieve set goals for its dimensions and motor power.
In addition, the engineers defined an automation process to manage the customer experience from arrival to the end of the flight. These tasks required close collaboration and communication among the engineering team, as well as extensive simulations to ensure the final product met Aerodium’s high standards for safety, performance, and customer satisfaction.

Completion of the production, testing, and acceptance of test equipment components.
Assembly of the test equipment will be carried out in May.
- Constructive solutions for the new tunnel concept.
Intensive work is currently underway on engineering solutions for the tunnel concept.
Connection nodes, materials, fastenings are being defined, load calculations, weights of components, and assembly sequence principles are being refined and updated.
6th stage from 01.04.2023 – 31.07.2024
All activities are over and the project is complete.
At this stage we have done:
- R1 test equipment prototype assembly works.
- Aerodynamic and flight tests.
- Installation and testing of the full automation system in the test tunnel.
- Constructive solutions for the tunnel, developed assembly plan, updated structural calculations and model after changes.
- The R1 tunnel concept and the constructive solutions were evaluated, and the design and solutions of the final concept were defined. Updated calculations, cooling system design and assembly process.
Final tests:
The automation system of the new tunnel concept was installed and tested, which facilitates the work of instructors and service staff. Instead, the Customer is directed to a maximally automatic self-service concept.
As a result: several shortcomings and necessary deviations from the original plan were identified. However, despite these, the concept and main idea works well and will be implemented in our latest R1 tunnel concept after making changes and adapting it to the flow of R1 customers.
