First look: China’s new carrier-based advanced twin‑engine jet trainer by has completed its initial test flight. Previously, the People’s Liberation Army Navy (PLAN) relied on the JL‑9G, a single‑engine trainer adapted from the Guizhou JL‑9/JJ‑7 airframe. However, as many observers have noted, all of China’s current carrier‑based combat aircraft are twin‑engine designs, making the older single‑engine JL‑9G a less suitable candidate for lead‑in fighter trainer (LIFT) roles.

An upgraded version of
China's JL-9 naval trainer jet was featured in a recent official report,
revealing newly added wingtip split rudders. A Chinese military affairs
expert said on Sunday that the technology will enhance carrier pilot
training and could be applied to future stealth aircraft.
A
regiment affiliated with the Naval Aviation University of the Chinese
People's Liberation Army (PLA) recently organized pilots to conduct an
aerial maneuvering exercise under combat scenarios, China Bugle, an
official media account affiliated with the PLA News Media Center,
reported on Saturday evening.
By putting a red team and a blue
team against each other in close-range combat training, the exercise
tested the pilots' comprehensive combat capabilities in complex
battlefield conditions.
The video report showed JL-9 trainer jets in action, with one deploying wingtip split rudders during landing.
Public
reports indicate that wingtip split rudders are a new feature to an
upgraded version of the JL-9 that made its maiden test flight in May
2020.
Compared to the original JL-9, the upgraded version of the
aircraft removed the drogue parachute installation located at the
vertical tail, and added wingtip split rudders, aiming to improve
stability and low-speed performance,
eastday.com, a Shanghai-based news website, reported at the time.
The
JL-9 trainer aircraft is used to train pilots for aircraft
carrier-based fighter jets, which do not use drogue parachutes, so it is
normal for the trainer to remove this design. The new split rudders act
as air brakes, helping pilots practice carrier landings more
effectively, Song Zhongping, a Chinese military affairs expert, told the
Global Times on Sunday.
Using split rudders instead of drogue
parachutes can also help lowering the weight of the aircraft, improving
overall performance, Song said.
The appearance of the upgraded JL-9 in an official report is an indication that the aircraft has technically matured, Song said.
Beyond
the JL-9, Song noted that wingtip air brake and split rudder
technologies have potential in future stealth aircraft. To achieve
better stealth, next-generation aircraft tend remove vertical wings, so
they need to use other types of stabilizers to control the aircraft, and
this is when alternative control surfaces like wingtip rudders become
relevant.
