conjecture on the "fujian" electric missile test

cctv released the "quenching" series, and the clips seemed to confirm that the "fujian" had conducted electric bomb tests, but it also seemed to confirm nothing. this of course caused a lot of speculation.

but since it is just speculation, we might as well expand it a little and make more guesses.

the fujian's electric missiles must be fully tested before they can be used in large quantities in daily operations. the question is how to test the electric missiles?

the small car test has been carried out, and there are pictures and videos to prove it. however, the small car test is only the most basic acceptance test, which is far from enough. in the end, it is necessary to use a real aircraft to test the takeoff of the electric missile.

it is generally believed that only the j-15t or equivalent aircraft has passed the test if it has been tested on electric missiles and tested while sailing at sea.

this is certainly true, but it doesn't have to be so absolute. the characteristics of electric missiles may make more gradual testing possible, which is greatly conducive to risk control. this is very important for the fujian and china's electric missiles. flat decks, catapult takeoffs, and electric missiles are all new, and taking them step by step is much more beneficial than a one-shot deal.

the biggest difference between electric and steam bombs is not that they can be deployed again faster, but that the ejection force is flexible and controllable. if necessary, the ejection distance can also be controlled. in other words, not only can the ejection force be adjusted according to the weight of the aircraft, but the ejection distance can also be adjusted when the ejection force is fixed. in an extreme case, it is also possible to eject at half the normal distance instead of at the end of the deck, as long as there is such a need. these two adjustments are not easy to achieve with steam bombs, and ejection basically requires full effort and full range.

in the era of steam bombs, the takeoff weight of carrier-based aircraft was not that different. the maximum takeoff weight of the light a-4 skyhawk is 11 tons, the medium f-18c is 23.5 tons, the heavy f-14a is 33.7 tons, and the large-looking e-2c is actually "only" 23.8 tons. a difference of 3 times is certainly not small, but if compared with the current range from drones to heavy carrier-based aircraft, the range is limited. the x-47b is the largest drone, reaching 20.2 tons; the large-looking mq-9b reaper is less than 6 tons; the once popular mq-1 predator is only 1 ton. according to outside estimates, the attack-11 is only 10 tons. on the other hand, the "medium" f-35a has a maximum takeoff weight of 29.9 tons, and the carrier-based f-35c should be heavier, but there is no official data. the next generation fa-xx (now discontinued, but it will definitely come back) is estimated to be more than 35 tons or even 40 tons.

when launching during navigation, as long as the wind and waves are not big and the navigation stability is good enough, the deck ups and downs will not have much effect on the launch, but the addition of headwind will have a great impact. anyone who has studied high school physics knows that headwind and launch force are equivalent. in the launch test, the characteristics of adjustable launch force and controllable stroke of the electric projectile can be used, starting with light aircraft, even in a parked state, step by step. the light drone launched from the ship is also quiet, so it may be able to complete the work quietly.

after the operating procedures and system performance are verified and familiar enough, the catapult weight will be gradually increased until one day a full-weight carrier-based aircraft is launched at sea. in the end, it is still necessary to launch the j-15t or equivalent aircraft during navigation, but there is no need to "get straight to the point" at the beginning.

the same goes for electric arresting. you can start by dropping the arresting cables of light aircraft and gradually increase the weight.

however, this is different from electric missiles. through the liaoning and shandong, china has considerable experience in the design and application of arresting cables. it is believed that electric arresting cables have a "non-electric" backup state, and even if the electromagnetic resistance-energy recovery part fails, it can effectively pull the landing aircraft. therefore, the reliability challenge of this aspect of the test is still relatively large, but the feasibility challenge is smaller than that of electric missiles. the design is more gradual and the threshold is lower.

is this really how the fujian's electric bombs and electric barriers were tested? tsk, do i look like someone who knows the inside story? but it seems that the truth will not be revealed for long.
