Analysis of Border Issues Between Bulgaria and North Macedonia pt.2

1. Technical Solutions for Border Surveillance

UAV Specifications and Capabilities

To effectively patrol the border between Bulgaria and North Macedonia, the use of vertical take-off and landing (VTOL) unmanned aerial vehicles (UAVs) is proposed, ensuring the necessary flexibility and responsiveness in challenging conditions. Let's consider the technical specifications of these aircraft:

• Wingspan: 1608 mm. The optimal ratio of wingspan to overall weight and engine power provides high aerodynamic performance. This parameter ensures stability and control during flight, which is especially important in conditions of variable winds typical of mountainous and open areas.
• Wing Area: 3757 cm². This characteristic is directly related to the UAV's load capacity and maneuverability. A larger wing area improves lift and allows the aircraft to remain stable at low speeds, which is critical when patrolling using cameras and thermal imaging devices.
• Maximum Takeoff Weight: 5.5 kg - 6.1 kg. This weight range allows the aircraft to be used for both general observation tasks and more specialized missions requiring additional equipment, such as radio reconnaissance modules or chemical detectors.
• Efficiency: 1.95 Wh/km at a 4.0 kg payload. This is an indicator of the UAV's energy efficiency, demonstrating how economically the aircraft consumes energy while performing tasks, which is especially important for long missions far from base stations.
• Cruise Speed: 45-60 km/h. This speed is optimal for patrolling, allowing the aircraft to cover large sections of the border and respond quickly to detected threats. Meanwhile, sufficient image detail is maintained for analyzing ground conditions.
• Maximum Rear/Front Propeller Diameter: 15 inches. These are the optimal propeller sizes to provide the necessary thrust, particularly important for vertical take-off and landing, as well as for quick altitude or direction changes.

Aerodynamic Properties

The aerodynamic characteristics of the UAV play a key role in its stability and efficiency under various operating conditions:

• Root and Tip Airfoils: The use of NACA 3412 profile ensures excellent aerodynamic qualities at low and medium speeds, which is ideal for patrol tasks requiring high maneuverability and stability.
• Root and Tip Chord: 255 mm and 162 mm respectively. These parameters determine the wing's shape and its ability to effectively generate lift at different angles of attack. The average chord of 212 mm provides a balance between lift and drag, allowing the drone to maintain stability and control even in challenging conditions.
• Root Incidence: 1° at a zero angle of attack at the wingtips. This ensures easy management of lift and allows the aircraft to adapt efficiently to changing flight conditions, such as strong gusts of wind.
• Aspect Ratio: 6.88. This value reflects the ratio of the wing's length to its average width, providing an optimal balance between lift and drag, particularly important for long flights at low altitudes.
• Max Lift-to-Drag Ratio (L/D): 14. This high value demonstrates the aircraft's ability to fly long distances with minimal energy consumption, which is especially important when recharging capabilities in the field are limited.
• Dihedral and Wing Sweep: Both parameters are 0°, indicating a straight wing design that provides high maneuverability and predictable behavior in the air. The negative sweep (-3°) of the trailing edge enhances stability and control at low speeds.

Infrastructure and Logistics

For the successful deployment of the patrolling system, it is necessary to thoroughly develop the infrastructure and logistics aspects of managing the UAV fleet.

UAV Fleet Management:

• Number of Drones: A total of 10 UAVs, with 5 constantly in active patrol phase and 5 in standby and recharging mode. This system ensures continuous border surveillance without significant downtime.
• Flight Duration: Each UAV is equipped with a 20,000 mAh battery, allowing for up to 2 hours of flight time. This is sufficient for completing monitoring tasks and returning to the base for recharging, with the drones covering significant distances.
• Rotation Schedule: A shift system is developed, where five drones patrol the border while the others recharge. This ensures 24/7 continuous patrolling, which is especially important for preventing illegal border crossings and smuggling.

Mobile Relay Station Placement:

• The choice of relay station locations is based on the need to maintain stable communication between the UAVs and ground control stations.
• Location 1: Near the village of Dolna Krushitsa (coordinates: 41°25'40.9"N 22°58'57.7"E).
• Location 2: Near the village of Kukurachavo (coordinates: 41.476744856873786, 22.974727148636823).
• These locations are chosen considering the terrain and accessibility, minimizing the likelihood of signal loss and ensuring a continuous data flow from the drones to the ground control stations.

UAV Maintenance and Readiness Plan:

• Regular technical maintenance and inspection of all drone systems are scheduled after each flight. This includes the replacement of worn parts, battery checks and recharging, as well as navigation system calibration.
