An upgraded version of China’s JL-9 naval trainer jet, featuring newly added wingtip split rudders, was recently showcased in an official report. This technological advancement is expected to enhance carrier pilot training and potentially be implemented in future stealth aircraft.
The JL-9 trainer aircraft, affiliated with the Naval Aviation University of the Chinese People’s Liberation Army, recently conducted aerial maneuvering exercises under combat scenarios. By pitting red and blue teams against each other in close-range combat training, pilots were tested on their comprehensive combat capabilities in complex battlefield conditions.
The introduction of wingtip split rudders in the upgraded JL-9 aims to improve stability and low-speed performance, as reported by a Shanghai-based news website. These new features not only act as air brakes during carrier landings but also contribute to lowering the overall weight of the aircraft, thus enhancing its performance.
Chinese military affairs expert, Song Zhongping, highlighted the significance of the upgraded JL-9 in demonstrating technical maturity. Beyond its current application, Song noted the potential of wingtip air brake and split rudder technologies in future stealth aircraft, especially in the context of alternative control surfaces for next-generation planes.
