Drone Reliability |Sanwood Technology Delivers Solutions!

Recently, a fire incident trended on social media, sounding the alarm for fire safety during autumn and winter. Once, it was firefighters charging into danger; now, with advancing technology, drones are increasingly integrated into daily life, significantly aiding firefighting efforts and becoming a new driving force for societal progress.

Yet, as these aerial devices find widespread application in extreme environments like firefighting, how can we ensure their stable and reliable operation amidst complex, demanding conditions? Sanwood Technology delivers dependable solutions.

Industry Landscape

In recent years, the global drone market has experienced explosive growth. As application scenarios continue to expand, drones face increasingly complex and volatile operational environments. Frequent incidents of drone malfunctions, loss of control, or even crashes not only incur economic losses but also potentially jeopardise public safety. The root cause of these issues often lies in inadequate simulation of real-world operating environments during the product development phase, leading to performance degradation or complete failure under extreme conditions.

Multi-dimensional Challenges

Drones are sophisticated devices integrating flight control systems, power systems, and sensor-communication systems. Their core components are highly sensitive to environmental factors such as temperature, pressure, and humidity:

Flight Control & Circuitry

Extreme Challenges: Humidity and heat causing circuit short-circuits; thermal shock inducing solder joint fatigue.

Core Tests: Constant temperature and humidity testing, rapid thermal cycling.

Reference Standards: GJB 150.9A-2009, IEC 60068-2-14.

Composite Structures

Extreme Challenges: Thermal cycling induces micro-cracks in materials; accelerated UV ageing.

Core Tests: Thermal cycling testing, UV ageing trials.

Reference Standards: ASTM D5229, GB/T 14522.

Power Systems and Motors

Extreme Challenges: Impaired heat dissipation and efficiency reduction at low pressure; lubrication failure at low temperatures.

Core Tests: Low-pressure (altitude) testing, low-temperature start-up and operation testing.

Reference Standards: RTCA DO-160G, GB/T 2423.1.
