Zhang Zhonglin: At a time when the country needed him most, he and the J-8 fighter jets stood firm together

Summary of Key Points

The passing of Academician Gu Songfen, known as the "father of the J-8 fighter jet," marks the end of an era that laid the foundation for China's aviation industry. He not only led the development of the J-8 series of fighter jets but also contributed to establishing a comprehensive system for aircraft design in China, turning the slogan "serving the country through aviation" into a lifelong commitment. From planting the seeds of patriotism during the War of Resistance against Japanese Aggression, to pioneering design standards from scratch, to personally accompanying flights to overcome testing challenges, and even overseeing major aircraft projects in his later years, his life encapsulates China's aviation industry's journey from imitation to independent innovation, from a state of poverty to becoming a major aviation power. What he left behind is not just a series of aircraft models but also a robust system and a legacy of spirit.

I. "Serving the country through aviation" is not just a slogan; it's a mission ingrained in the bones

The commitment of Gu Songfen and his generation of early aviation designers was not something they chose voluntarily; it was forced upon them by history. During the war, when Japanese planes bombed their homes and caused suffering to their loved ones, they realized that "the enemy could fly freely, but we had no means to defend ourselves." This humiliation made the idea of building our own aircraft an unwavering goal.

They had options: Gu Songfen could have chosen a less challenging field, and Cheng Bishi could have pursued other engineering projects, but they both chose aviation, which was in greatest need at the time. There were no career plans; instead, they did what the country required—whether it meant developing trainer planes like the J-7 or fighter jets like the J-8. Even the basic norms of the aviation industry (such as how to turn blueprints into functional aircraft) had to be established through trial and error. For them, their personal destinies were tied to the nation's aviation aspirations, and "serving the country through aviation" was a promise fulfilled with their youth and lives.

II. The J-8: China's coming-of-age moment in aviation

Many know the J-8 as Gu Songfen's masterpiece, but its significance goes beyond being just a fighter jet. It marked the first time that China's aviation industry learned how to build a supersonic aircraft from scratch.

In the early days, China relied on "importing and imitating" (such as copying Soviet designs), but this approach did not transfer the necessary skills. With the deterioration of Sino-Soviet relations and the loss of foreign support, China had to rely on its own efforts to develop the J-8. The development process involved learning everything from scratch, from theoretical calculations to wind tunnel tests, from engine matching to flight testing.

The later J-8II model was even more groundbreaking: it featured side intakes for the engine, allowing for a larger radar, which meant the aircraft had to be designed with multiple systems (radar, fire control, avionics, etc.) in mind. As the chief designer, Gu Songfen had to coordinate all these aspects, leading to the establishment of the "chief designer system" and "systems engineering methodology"—in other words, one person was responsible for ensuring that all components worked together effectively to create a combat-ready aircraft.

The true value of the J-8 series lies in its role in transforming China's aviation from a follower to a leader, marking a significant milestone in its development.

III. "Three flights into the sky": Using the most straightforward methods to do the most reliable work

Gu Songfen's dedication was not just theoretical; it required practical action and risk-taking. During J-8 flight testing, they encountered a critical issue of transonic flutter (the aircraft would shake excessively at high speeds). Without advanced telemetry equipment, Gu Songfen personally accompanied the J-8 flights from a J-7 trainer, closely observing the airflow patterns to identify the problem. This approach was common among that generation: if there was no simulation software, they did the calculations by hand; if there was no testing system, they conducted tests themselves. They were not afraid of danger because they understood that a poorly built aircraft would weaken the nation's capabilities. Gu Songfen once said, "I didn't think about the risk; I just wanted to solve the problem." This reflects the sense of responsibility of that era—when it mattered most, they stepped forward.

IV. A lifetime of dedication: No retirement for those who serve the country through aviation

Even in his 70s, Gu Songfen continued to contribute to China's aviation industry. For example, during the development of the ARJ21 regional aircraft, there were issues with overweight and airflow distortion, leading to suggestions to start over with a different design. Gu Songfen, along with his team, determined that the problems could be resolved without starting from scratch. Later, he also provided advisory support for projects like the C919 and Y-20, using his engineering expertise to help young professionals. For him, retirement meant stepping back from frontline positions, not leaving the aviation industry altogether. He remained involved in the development of sixth-generation aircraft until the end of his life, believing that "as long as the country needs it, I must continue."

V. Spirit and system: Legacy for China's aviation

Gu Songfen's legacy is more than just a series of aircraft models. It includes:

1. A comprehensive research and development system: From design standards to the chief designer role, from systems engineering to flight testing, this framework has been essential for China's ability to develop advanced aircraft like the J-20 and C919.

2. The spirit of serving the country through aviation: The commitment of that generation to do what the country needed has inspired generations of aviation professionals. Today, Shenyang Aircraft Corporation's entry into the global sixth-generation aircraft club is a testament to their achievements.

Gu Songfen's life is a prime example of integrating personal ideals with the nation's destiny. He may not have left behind grand statements, but his lifelong efforts have transformed China's aviation from nothing to something powerful. For everyone, his story teaches us that true patriotism means doing what the country needs and doing it to the best of one's ability.
