Recent satellite aerial to the tarmac is 35 stealth aircraft flight test phase of the fighters, can see from the picture at the moment there are at least two fighters 35 and 15 are two fighters involved in flight, it not only represents the fighters 35 aircraft identity, at the same time more than test flight, also represents the fighters 35 test progress is accelerated, the distance and equipment service time not far away.But look this satellite aerial images will find a problem is, 35 aircraft parked on the tarmac fighters and 15 fighters, although the four aircraft are in a state of wings folded, covers an area of 35 but after folding wings of fighters, 15 also was larger than fighters, to know the fighters 35 normal state, the smaller than fighters 15 a big circle.So why is it that the J-35 is one circle smaller than the J-15, but with folded wings it is larger than the J-15?After all, the deck and hangar of an aircraft carrier cost a lot of land. The smaller the area of a carrier-based aircraft after folding its wings, the more carrier-based aircraft an aircraft carrier can carry.In fact, the J-35 wing folding, but than their own big circle OF J-15 is larger, there are two main reasons: first, J-15 and SU-33, because of the positioning of the twin-engine heavy fighter, the whole body is very large, so in the ship folding wing, the wing folding point design is closer to the inside;At the same time, in order to reduce the width of the folded wings as much as possible, and thus increase the number of aircraft on the carrier, not only the wings can be folded, but also the flat tail can be folded.The biggest advantage is that after folding the wings and tail, the width of the whole aircraft is reduced by nearly half. For Kuznetsov and Liaoning, which have a narrow internal space, the width of the carrier-based aircraft wings is narrower after folding, which means that more carrier-based aircraft can be carried in a smaller space.But doing so the biggest drawback is that in order to narrow the area as much as possible, annihilates 15 and Sue 33 fold point location is on the wing, which makes the two flanks around can only design under a heavy weapons hanging point (strength limit because the wings folding mechanism, the folded section does not have overloaded mount), calculate the fuselage on abdomen, the machine and only three heavy weapons hanging points,This severely restricts its carrying heavy missiles to carry out land – to – sea attacks.Second, for THE J-35, as China’s new generation of stealth carrier-based aircraft, the j-35 aircraft carrier will be equipped with large aircraft carriers with larger tonnage, hangar space and catapult in the future. Due to the larger tonnage, hangar and deck space, the requirements for the J-35 after folding wings are relaxed.So for THE J-35, first of all, there is no need to fold the flat tail, which not only increases the structural strength of the flat tail, but also reduces the weight problem caused by the folding mechanism;More importantly, the flat tail does not need to be folded, so when the main wing is designed to fold, it only needs to be slightly wider than the flat tail width.The biggest advantage of this is that with the wing fold closer to the outside, two heavy weapon hardpoints can be designed on the inside, which is 67% more than the j-15’s hardpoints on the inside including the belly of the fuselage.In this way, two more heavy missiles can be mounted, or four to eight more missiles can be added by using the composite pylon, greatly improving the attack capability.The folding point of the wing of the F35C carrier-based aircraft of the US Navy is also relatively outward-looking. The wing span of the F35C of the Navy is 2.5 meters wider than that of the F35A of the Air Force and the F35B of the Marine Corps. Normally, it is necessary to reduce the width of the folded wing.Many people may worry that the folding wings of the J-35 and F35C stealth fighters are designed so far out that it is unnecessary.Since the J-35, like the F35C, is a stealth fighter with a built-in bomb bay, what about two more heavily loaded weapons hangpoints on each wing?It’s useless if I don’t use it.This problem is not only for THE J-35 and F35C, is a very realistic problem, in fact, for all the current stage of stealth fighter, the lack of ammunition has been the biggest problem.For example, F22 and J-20, with a maximum takeoff weight of about 38 tons, are equipped with built-in bomb bays that can only be mounted with air missiles, so they are not capable of land and sea attacks.At the same time, the F-35 stealth fighter aircraft, although it has two deep and large internal magazines can mount light anti-ship missiles, but the number of mounted missiles is still seriously short.So what’s the best way to solve this problem right now?In fact, it is to use the external mounted stealth pod, which can not only maintain the best aerodynamic layout of the missile, but also build it into the stealth pod that can be mounted under the wing, and solve the multiple problems of the lack of missile load of stealth fighter and the external missile will destroy stealth.Therefore, the weight of the stealth pod itself is not low for the stealth fighter aircraft that needs to be attached to the stealth pod, so only the heavy weapon hanger point can meet the mounting requirements of the stealth pod.So for a stealth fighter, each side of the wing under a heavy weapon hanger point, means that it can mount two more stealth pods, so as not to destroy the stealth premise, greatly improve the missile load, and this is why including F35C and J-35, wing folding point design is more outside the real reason.
