Internal tempering: Complete comprehensive "physical examination" in the factory

The successful internal testing was fully conducted at Safran Aviation's dedicated factory facilities. During this phase concluding in late 2025, the R&D team rigorously adhered to the end-to-end testing framework encompassing "components → systems → complete aircraft → operational scenarios". They systematically completed critical tasks including flight control software algorithm validation, power system coordination debugging, structural strength static testing, and complex weather adaptability assessments. Through multiple rounds of ground static tests and low-altitude flight validation, the aircraft's core performance characteristics—particularly hover stability—were thoroughly verified.

· Flight control system debugging: Completed full-spectrum ground simulation and field validation of flight control algorithms and software.

· Powertrain's Heart' Tuning: The hybrid system underwent comprehensive performance testing and efficiency optimization.

· Robust structural framework: The fuselage has undergone multiple static and fatigue tests to ensure structural safety and reliability.

· Full-system functional verification: Core functions including hovering, low-speed maneuvering, and mode switching were successfully validated in a controlled environment.

The rigorous testing conducted right at the doorstep has established a solid and reliable technical foundation for the public debut of SF20V.

Tianzihu Airport: About to Make Its Public Debut

As planned, the SF20V's official public debut flight will take place at Anji Tianzi Lake General Aviation Airport in Zhejiang Province. With its excellent airspace conditions and comprehensive flight support system, this airport serves as an ideal venue for public flight demonstrations.

All preparatory work for this maiden flight—including airspace coordination, airport ground support, air traffic control, and external tracking and control systems—has been completed. The support team is now conducting final scenario-based optimizations of the public flight demonstration plan, tailored to the unique airspace and environmental characteristics of Tianzihu Airport.

Core Product: Zhongming Zhenchi, A Thousand Miles of Flight

As the flagship product of Suofu Aviation's future low-altitude travel strategy, the SF20V combines VTOL flexibility with fixed-wing cruising efficiency, boasting a maximum range of 1,200 kilometers. Its prototype, launched in 2024, features a high-safety redundancy design as its core concept.

About SuoFu: Building the Future of Air Traffic

Zhejiang Suofu Aviation Technology Co., Ltd. (headquartered in Linping District, Hangzhou) was established in December 2024 with a registered capital of 30 million yuan. The company focuses on the research and development of intelligent aircraft and the construction of a low-altitude economic ecosystem, while also expanding into extended fields such as general aviation services and civil aircraft pilot training. The SF20V represents a significant milestone in the company's implementation of its product roadmap.

The company has subsequently planned six series of aircraft models, including the SF60V and SF50X hydrogen-powered high-speed planes, while striving to establish a comprehensive low-altitude navigation service platform to seize opportunities in the trillion-dollar low-altitude aviation market. Currently, the company is advancing a 30-million-yuan angel round financing, with funds primarily allocated to the airworthiness certification and initial mass production of the SF20V.

Industry significance: Paving the way for the development of China's low-altitude aircraft

Industry experts note that SF20V's successful completion of rigorous in-house factory testing and subsequent public airport debut sets a valuable benchmark for the development, testing, and airworthiness certification of China's new vertical takeoff and landing (VTOL) aircraft.

Its hybrid fuel-electric system and outstanding long-range capability are expected to play a significant role in diverse scenarios such as high-end business travel, pilot training, aerial tourism, and emergency cargo transportation, providing practical solutions for the emerging China low-altitude economy.

From rigorous validation in the factory testing zone to its public maiden flight at Tianzihu Airport, the Soberon SF20V is steadily progressing through the critical transition from product to market.

In early 2026, we can't wait to see the new trail it leaves across Tianzi Lake.
