QYRAN E-1

Power lines run for hundreds of kilometres across steppe and mountains, and checking their condition still means sending a crew out, climbing the pylon or taking the line out of service. Qyran E-1 moves that work into the air: the aircraft orbits every pylon through pre-computed viewpoints while the thermal channel reveals a fault long before it becomes an outage.

At the core of the complex is KÖZ-640, our own gyro-stabilised electro-optical and thermal module. It is built around the uncooled LYNRED PICO640S sensor: 640 × 480 pixels on a 12 µm pitch, thermal sensitivity better than 30 mK, under 130 mW of draw and shutterless operation — the fewer moving parts, the more dependable the module under vibration.

The second key element is a long-focus lens for the LWIR band (7–14 µm). Its narrow field of view lets the survey be flown from a safe stand-off: at 30 metres one pixel covers about 7 mm, so a clamp or a single insulator cap reads as a distinct thermal detail rather than a blur.

A visible-band (EO) camera works alongside the thermal channel, while the onboard processing unit fuses the two frames, records radiometric data and ties each frame to GNSS marks. In flight the operator already sees the temperatures of identical elements compared side by side; after the flight the system compiles a defect table with the pylon number, the phase and the coordinates.

The programme is under development: the opto-mechanical assembly and the control electronics are built and are going through laboratory testing. The design accounts for the electromagnetic environment of high-voltage assets — the power input is galvanically isolated, the housing is shielded, and heading comes from a dual-antenna GNSS rather than a magnetometer.
