As part of the "Mechanical Engineering Competence Center" project, SIA "TEMESO" is starting on June 1, 2023, research project no. 5.1.1.2.i.0/1/22/A/CFLA/006 "Improvement of the control system and production technology of the unmanned aerial vehicle (target platform)". The aim of the research project is to develop a new UAV control station and antenna system developed by the company, as well as to improve the manufacturing technology of composite parts used in the company.

​

In the period from 01.06.2023 – 30.09.2023:

Within the framework of the intermediate stage, SIA "TEMESO" developed a CAD model of the ground station and its component list, the first prototype of the antenna system and samples of parts for further research of the production technology. In parallel with these works, tasks were defined for further research works planned in the next intermediate stage.

​

In the time period 01.10.2023 – 31.12.2023, two important works have been carried out:

1. The scientific study "Optimization of control frequency, communication and antenna" was carried out.

2. The scientific study "Improving the production technology of flax composite and testing samples" was carried out.

As part of the "Optimization of control frequency, communication and antenna" research, more suitable antennas for the UAV system and system parameters that allow to increase the operating distance were selected. In the tests of the antenna system, a working distance of 48.7 km was achieved with communication quality indicators corresponding to the operation of the system. At distances closer to the operation, but with a larger sector of operation, another antenna was found. A set of these actions gathered potential future improvements to further increase operating distance. All results were summarized in a study report.

As part of the study "Improving linen composite production technology and testing samples", the composite gluing technology used in the company was explored and tests were carried out with various material combinations and technological changes. As a result, a technology map and a database with various technology configurations and parameters of manufactured parts were compiled. 

​

In the time period 01.01.2024 – 31.03.2024, the design of the prototype of the Ground station has been completed and the CAD model and description for the manufacturing of production forms have been developed, as well as the four of six modules of the prototype of the GS have been completed, manufactured and configured:
1. The module of transmitters and antennas placed in the unmanned aerial vehicle;
2. GS Ground antenna module;
3. Ground station system power supply module;
4. Ground station remote control module;
All these modules are fully assembled and set up. We expect to manufacture the remaining two modules (the basic module of the Ground station and the control computer) within the 4th intermediate stage. After the production of these modules, the Ground station prototype will be fully assembled and can be fully tested.
Extensive information analysis work has been carried out in the field of production technology improvement and a precise plan for the next steps has been drawn up to create a test batch of parts according to the knowledge gained during the project. Also, work has started on milling the models, which will make it possible to make a set of forms.
When planning the testing of the Ground station, it was concluded that for safe and controlled testing it is necessary to create a flying transmitter-receiver station (in the form of a quadcopter). This will allow tests to be carried out more easily and without significant limitations, which would be significantly more difficult with a large fixed-wing UAV. Work on the creation of this platform has already begun.

​

In the time period 01.04.2024 - 30.06.2024, the production of the prototype of the Ground station has been completed, the testing of the Ground control station has been carried out, and a batch of test parts with the improved linen composite technology has been produced.

In general, the planned results of the project have been successfully achieved. A prototype of the Ground control station has been created. It has been functionally tested, which shows the achievement of the initially set goals:

1. Stable operation of the system

2. System operation up to a distance of 40 km.

3. System modularity and rapid deployment.

The desired goals have also been achieved in the production technology section. Improved production technology, as a result of which UAV fuselage parts are manufactured with higher surface quality and greater strength. Natural fibre reinforcement material (linen fibre) has been preserved for these parts. On the other hand, the precision of the parts allows for higher quality manufacturing of the aircraft structure and improves the appearance of the final product. Hatches, wings and winglets have a more precise fit connecting to the central part.

The contract studies carried out within the project have made it possible to gather a large amount of theoretical and practical (laboratory measured) information. It significantly helped to carry out the project and provided a vision for the further development of the Unmanned Aircraft System. Further, it is planned to develop the long-range communication of the aircraft, improve the performance parameters of the unmanned aircraft and improve the operation of the unmanned aircraft system in the conditions of disturbances
