Once the launcher pulls the trigger, the rocket works as follows:
1. The powder in the combustion chamber is ignited, pushing the rocket forward to fly away from the launcher. The initial velocity of the rocket is about117 m/s.
2. After the rocket leaves the barrel, the stabilizing wing opens and the rocket rotates.
3. After the rocket flies for 0. 1 s, about 1 1 m, the rocket engine starts and the rocket accelerates to 294m/s until it reaches the target.

RPG-7 rocket was first ejected from the launcher by recoil propellant and began to fly, but the energy provided by the propellant could not make the rocket fly very far. When the rocket flies away from the launcher for a certain distance, the rocket extended-range engine at the tail of the missile body is started, and the newly provided thrust can keep the missile body at a constant speed or even accelerate its flight.
At most, the initial speed of 100 is buffered by the spring, and the speed is 0. Even if the rocket extended-range engine is started, it is a process of accelerating from zero, and it will be thrown out immediately after being caught.
And is this RPG made by American Arsenal or China Arsenal? Even if it is made in China, there is no 100% guarantee that there will be no problems, let alone rockets made in poor places like Africa. Can the charge be calculated according to the standard?

This is an RPG29 with a thermobaric warhead. The thermobaric warhead weighs more than 7 kg, and its initial velocity may be lower than 280m/s, but it will not be much lower.
After hitting the human tissue, it bypassed the hard bone and did not detonate the fuse, but only penetrated this part of the human tissue, so it is speculated that,
With an initial speed of 100 meter per second, the lighter 2kg RPG7 can be stopped by manpower.

Explain militarily. It has little to do with the sincerity of grille armor or something. . After all, it is a spring bed, and the design is at most a shock. I never wanted to stop rockets, so naturally I can't compare with real armor. But I think the design of this lens is reasonable. Why? Because of the design characteristics of rocket launchers. First, how hot is the kinetic energy of the rocket? Why can't they penetrate the spring bed? In fact, this is because the red scarf fighter who launched the rocket is too close to the cold front, about ten meters. Rockets are not bullets. The bullet is only propelled by propellant. The closer, the better. But rockets are much bigger than bullets, and propellant alone can't go that far, so there is an engine in the rocket. RPG engines need to fly more than ten meters to start, that is to say, when the cold front blocks the rocket, the rocket flies by inertia, with no thrust and low speed (only relative to bullets). In addition, the network structure of the spring bed itself can absorb some kinetic energy well, so it is possible for the rocket to get stuck on the spring bed in the movie. & ltimg src = "/50/v2-75 baa 28 a 59 b 76 c 9 1 19 c593 df 02646 c 7b _ HD . jpg " data-raw width = " 750 " data-raw height = " / Kloc-0/334 "class =" origin _ imagezh-lightbox-thumb "width =" 7 50 "data-original ="/V2-75 Baa28A 59B76C9165438 Second, the rocket hit the spring bed. Why didn't it detonate? Seriously classified and discussed as follows: ① If it is a delay fuse, it is normal not to explode. Because the rocket launcher is designed considering its wide use in street fighting, in order to protect the rocket launcher, the delay fuse is usually 0.2-0.5 seconds, which can be longer after preset, so the cold front only ten meters away from the rocket launcher will naturally not explode immediately when it catches the rocket. (2) If it is a trigger fuse? The principle of trigger fuze is a piezoelectric device, which is detonated by the potential difference generated when the warhead feels the pressure and reaches a certain value. The gap of the spring bed used for the cold front in the film is relatively large, so as long as the conical warhead of the rocket does not hit anything, it will not cause an explosion. (In fact, even if the warhead touches something, if it is soft or loose, the pressure will not reach the rated value. Such as the open Philippines) < img src = "/50/v2-0cd01058c8b6690fc3b962b99f95ef1 A _ hd.jpg "data-rawwidth =" 750 "data-rawheight ="1334 "class =" origin _ imagezh-lightbox As for why the rocket that was not triggered was blown up as soon as it was abandoned by the cold front? Since there was no trigger, why didn't he drag the rocket down and hang it around his neck? Do you really think it won't blow up without triggering it? Nuo Nuo, the Soviet expert is very cunning. If the rocket is not accidentally triggered (for example, it encounters a cold front wearing the protagonist's aura or misses normally), the rocket still has 4.5 seconds to self-destruct the fuse, and it will automatically detonate after 4.5 seconds, regardless of whether it hits or not, so as to avoid accidentally injuring its own people. & ltimg src = "/50/v2-9558884 e 740 EDB 3234224 c ac0 f 1 de 82 b _ HD . jpg " data-raw width = " 750 " data-raw height = " 1 334 " class = " origin _ image zh-light box-thumb " width = " 750 " da ta-original = "/ V2-9558884E740EDB323424CAC0F654334 So the veteran cold front who is familiar with RPG-7 performance (this skill should have been unlocked when he was groping in Africa) just grabbed the spring bed for a second or two and threw it away decisively, so the self-destructive rocket exploded, leaving a group of anti-nationalist domestic blacks not paying attention to verification. I didn't know that the shield of the US team was the real solution. /note/674 103689/

Russia shows shields to stop rockets.
In an operation on 20 13, members of the special forces of the Russian Federal Security Service blocked an RPG22 rocket with a shield. Because the rocket failed to detonate, although the shield hand lost the ability to act on the spot after being hit, it did not matter afterwards.
