Are you it's not 10%?
Yeah I’m sure they said 1%, original poster said the first hand materials claimed so.

Snippets from an academic paper that examines the performance requirements of used by carrier arresting gears. The paper uses the parameters of a certain carrier fighter to carry out simulations of the sheave dampers.
Translation of the text in the first image:
Table 2 mentioned in the first image. It lists the fighter's takeoff weight as 18 tons, with landing speed of 55m/s.

I am bit confused by the texts in Chinese and the table. The texts talks about take-off speed of 52m/s (why), but the simulation and table 2-1 is about the arresting. The table also shows the landing speed being 55m/s, shouldn't the mass of the aircraft 18t being the landing mass instead of takeoff mass?Snippets from an academic paper that examines the performance requirements of used by carrier arresting gears.

Here's the . I haven't got the time to read through the thing, but I think the answer lies with the scope of the paper, which is much larger than just simulating the arresting gear.
Abstract: The various factors affecting the carrier aircraft catapult take-off safety are analyzed in detail. The nonlinear six-degree-of-freedom motion model of the aircraft in climbing phase is established. The effect of the rolling and yaw motion and crosswind on the catapult take-off characteristics is simulated and analyzed, and it is found that the main influences on the rolling and side-slip movement of the carrier aircraft after leaving the ship are the deck rolling motion and crosswind disturbance respectively. The nonlinear dynamic inverse control method is proposed to keep the nonlinear features of the model, make the result more precise, and realize the decoupling control of directional and lateral motion states. The simulation result indicates that the designed lateral control law can ensure that the rolling angle of the aircraft meets the safety criterion of not exceeding 5° within 3 seconds after leaving the ship and that there will be no obvious side-slip phenomenon due to crosswind disturbance, which can guarantee the safe take-off of carrier aircraft.

They are from different papers.
18t is only mentioned in "Tab.2-1 Parameters of the sheave damper simulation model." Sheave Damper is a component of arresting gear, so 18t is the landing mess of the aircraft of the simulation model.
If I may hazard a rough guess: 14.5t empty weight, 1.5t fuel (in case it needs to bolter) and 2t for munitions which is more than adequete for 4 x PL-15. Take this with a HUGE grain of salt sinse we literally have no figures for the empty weight of J-35. Also I believe standard procedure for superhornet (with 2 x F414 which would likely be very roughly comparable to WS-13 or whatever the J-35 is currently using) is to carry 2000lb of fuel when landing so the 1.5t from my estimates may be a bit overkill.
