He devoted all his life to serving as a scout and mechanic in the guerrilla forces, eventually becoming an excellent aircraft designer. He led the development of the J-10 aircraft, which had flown over Tiananmen Square four times and was inspected by the Party and the people. ■ He is Song Wencong, an academician of the CAE Member known as the "father of J-10". On October 1, 2009, the military parade celebrating the 60th anniversary of the founding of the People's Republic of China was grandly held at Tiananmen Square in Beijing. A white haired elderly man was invited to climb onto the observation platform to participate in this world-renowned National Day celebration. As the reading party passed by, the old man raised his head time and time again, looking eagerly into the sky. Suddenly, a roar came from the horizon. 12 aerial echelons composed of 151 domestically produced aircraft flew over Tiananmen Square in sequence - the old man's eyes lit up instantly, and at this moment, the J-10 aircraft echelon flew over! As if seeing his lovely children, the old man stood up excitedly with a joyful smile on his face. He subconsciously raised his right hand and gently waved to the fleet. The name of this old man is Song Wencong, and he led the development of the J-10 aircraft. After participating in the National Day parade in 2009, the J-10 aircraft underwent several upgrades and upgrades, flying over Tiananmen Square three times in 2015, 2019, and 2021 to receive inspections from the Party and the people. On this day, I have been looking forward to it for over 30 years. "The spring of 1998 arrived slowly. March 23rd is a day of special significance in the history of Chinese aviation. On this day, China's self-designed and developed third-generation fighter jet, the J-10, which can rival the world's advanced fighter jets, made its maiden flight. The weather is not beautiful, the visibility at the airport is poor, and the sky is gray. On the podium not far away, leaders from the military and aviation industry group quietly watched the fighter planes on the runway; On the east side of the runway, engineering and technical personnel eagerly awaited that exciting moment. Song Wencong did not take his seat on the podium, but arrived at the apron early and calmly watched the maintenance personnel conduct the final inspection of the plane. As the chief designer of aircraft, his responsibility is heavier than Mount Tai. Overall, this aircraft went through a long period of 12 years from its inception to its first flight. In order to develop this type of aircraft, I don't know how many people have put in their youthful passion and intelligence. Song Wencong was now 68 years old, and the dust of time had engraved wrinkles on his face; The wind and frost of time have whitened his beard and hair. Today, the plane is finally about to make its first flight! Song Wencong keenly sensed the tension in everyone's hearts from their cold and serious expressions. Who wants to say they're not nervous when the new plane flies first? That's fake. Song Wencong also had pressure, but the design and development of the new machine had undergone rigorous argumentation and repeated experimentation, and his heart was more composed of a sense of calm and confidence. After the plane inspection was completed, Song Wencong calmly signed off and let it go. He gestured to the test pilot from a distance and watched him board the plane. On the tower, the commander issued instructions to prepare for takeoff. After waving to everyone, the test pilot closed the hatch. At this moment, Song Wencong couldn't help but get excited. Can lead the development of the world's first
