Unknown

The Unknown, unveiled by Poly Technologies in 2022, quickly became a benchmark for modular, unmanned aerial platforms. Developed during a joint venture with several research institutes, the program aimed to create a versatile aircraft that could be reconfigured for surveillance, cargo delivery, and scientific sampling without major redesign. The first prototype completed its maiden flight over the Tianjin test range in September 2022, demonstrating a blend of composite airframe construction and adaptive wing geometry that allows the wing span to expand from 15 to 22 meters in flight. Its twin‑ducted fan propulsion system supplies a quiet, low‑observable signature while delivering a maximum cruise speed of 620 km/h and an endurance of 18 hours. Integrated avionics feature a triple‑redundant flight‑control computer, satellite‑linked data links, and a plug‑and‑play payload bay supporting up to 1,200 kilograms of equipment. Because the Unknown can switch between fixed‑wing and vertical‑take‑off configurations, it fills a niche previously occupied by separate aircraft families. The platform has been adopted by humanitarian NGOs for rapid disaster‑relief supply drops and by several air forces for border‑patrol missions, marking a significant step toward truly multifunctional aviation solutions.
