March 7, morning, Maria Engineering Equipment Factory.
A technical soldier pulled the lead, threw a grenade into the distance, and quickly fell down.
3 seconds later, 35m away.
"boom!"
After the grenade explodes, a shock wave of explosive shrapnel with a radius of 7m is generated. The farthest shrapnel produced by the explosion is still lethal after flying 50m away.
"good!"
Tangning praised loudly and clapped her hands in applause!
"Pop!" "Pap!" "Pap!"...
The king cheered and applauded, and of course his entourage also applauded.
Although this was flattering, the effect of the grenade explosion just now was really outstanding and convinced everyone.
This 09-type wooden handle grenade is really powerful.
"Mark, you did a very good job. The effect of the grenade met my expectations."
Tang Ning was very satisfied with Mark, the director of the engineering ordnance factory, who perfectly restored the Type 67 grenade.
“We in Brazil finally have our own hand grenades, which is gratifying.
Mark, I hope the remaining two grenades will be successful as soon as possible, and then I will congratulate your entire factory and award them. "
"Yes, Your Majesty, we must complete the other two enhanced grenades as soon as possible."
Mark said proudly, puffing out his chest.
"With the three grenade designs given by His Majesty, I am confident that they will be completed in the first half of this year."
"Well done, I believe in you!"
Tang Ning really believed that they could succeed quickly, because the three grenade designs he gave were completely fine according to Brazil's current standards.
Oriental wooden handle Type 67 grenades, Oriental wooden handle Type 73 grenades, and Japanese Type 91 grenades are all simple and easy to make, and there are not many technical problems.
Brazil's current arsenal level is fully capable of designing and producing these three types of grenades.
The Type 67 wooden handle grenade was once a mass-produced weapon of the Eastern powers during the Cold War. An upgrade of the original Type 61, it was produced in large quantities and was also equipped to militiamen. This grenade has been used as a military training bomb until the 21st century.
Performance: The total bomb mass is 600g, the diameter is 48mm, the total length is 204mm, the main charge is 38g TNT, which can produce 70 to 110 fragments, the killing radius is 7m, the safety distance is 30 meters, the operating temperature is -45 to +50 degrees Celsius, the fuze is mechanically activated hair.
Its main advantages are simple structure, low cost, and easy mass production; its disadvantages are that the mass of the entire bomb is too large, the volume is too large, and the number of fragments is small. Structural features: The firing mechanism of this grenade adds a fuse between the fuse and the detonator. One end of the fuse is engaged with the fuse and the other end is engaged with the detonator. The joint is coated with sealant to prevent moisture and fire. , the ignition head agent uses lead thiocyanate instead of mercury fulminate, and at the same time strictly controls the production process, thus better solving the problems of early explosion and susceptibility to moisture.
"The Romance of Fairy Wood"
The Type 73 grenade, in addition to having the function of a general grenade, is also suitable for attacking high places, water surfaces, and mobile targets.
Performance: The bullet weight is 190g, the bullet diameter is 42mm, the bullet length is 88mm, the powder is RDX, the charge is 40g, the fragments are 580, the killing radius is 8 meters, the safety distance is 35 meters, the operating temperature is -45 to +50 degrees Celsius, the fuze is mechanically activated hair.
This grenade has a simple structure, low cost, and is convenient for mass production. The missile body consists of explosives and 580 steel balls fixed in the upper and lower shells. The fuze is composed of insurance, release insurance mechanism and impact explosion mechanism. When the safety hoop is pulled and thrown, the safety cover and sleeve rise slowly under the action of the cone spring and sleeve spring. The jump pin and safety spring jump out one after another, and the fuze is released from safety and becomes ready to go. When it hits the target, it falls completely to the body, releases the firing pin, and triggers the detonator to detonate.
The Type 91 grenade is a grenade developed by Japan after carefully studying the use of grenades and mortars on the battlefield. It includes hand grenades, rifle grenades, and grenade/light mortar shells. This grenade can be adapted to various close combat environments such as cities, trenches, jungles, etc.
Performance: Total weight 530g, total length 98mm (about 5 inches), diameter 5cm, charge type TNT, charge amount 65g, detonation method 4~5 seconds burning fuze, killing radius 7~10m
The Type 91 grenade uses a hemispherical top, and there is a screw bolt hole at the bottom of the body that can be connected to the spare propellant tank required when launching through a grenade launcher, or when used as a rifle grenade, through the tail fin required by the leading type, through the leading type The launcher shoots out. The fuze is an impact trigger type, which is triggered by pulling out the safety pin and tapping the top of the grenade cover. This grenade has a 7-8 second delay before exploding. This feature was incorporated into the Type 91 so that it could be used as a rifle grenade or as ammunition for the Type 89 grenade because the longer fuse provided a longer flight time and could attack farther targets. When it is connected to the tail fin as a rifle grenade, or to the base containing the firing point and propellant as a mortar shell, the fuze will automatically activate because the firing pin will push against a weak spring due to the force of the launch and be pressed into the interior. In addition, the Type 91 grenade can be used as a booby trap after the safety pin is removed and placed on the floor or under a chair.
These three grenades are the product of decades later, but the production model is sufficient now.
The development of hand grenades is similar, and there are not many technical obstacles. Especially wooden-handled grenades, the production process requirements are lower, and small workshops can produce them.
These three types of grenades are more than enough for current use, and their respective uses are also very simple.
The Type 67 grenade with a wooden handle weighs 600 grams and has a slightly weaker explosive power, but it can be used as a training ammunition for Brazilian individual soldiers and can also be equipped with militiamen and armed police.
The Type 73 wooden-handled grenade is light in weight at 190g and powerful. In addition to having the function of a general grenade, it is also suitable for attacking high places, water, and mobile targets. This grenade is directly equipped with short-range support firepower for the regular army.
The Type 91 grenade has a heavier mass of 530g, average power, and long delay, but it has great applicability and can be used as individual hand grenades, rifle grenades, grenades, and mortar shells. It can be used as small support firepower by regular troops.
Maria Engineering and Equipment Factory mainly produces basic ordnance equipment.
In addition to the production of hand grenades, small pistols, and pistol bullets, it mainly produces: motorcycles, military bicycles, military tricycles, ordnance mazas, ordnance shovels, ordnance pickaxes, ordnance crowbars, ordnance wrenches...
In this regard, except for motorcycles, there is not much technical content in other products, but they have a characteristic, that is, the basic usage is large.
Regarding motorcycles, Tangning couldn't help Brazil, but the others were very simple and there were people who could copy them.
Tang Ning directly designed the 38 large bar, self-propelled tricycle, 204-type army shovel, 205-type engineer shovel, Q1-type wooden handle folding shovel, 102-type small army pickaxe, Q3-type three-folding shovel, and other basic engineering equipment designs. , let the Brazilian engineering equipment factory produce it.
"These engineering tools have been produced and are very helpful to our Brazilian soldiers at the bottom. But when will military three-wheel motorcycles be produced?"
Tang Ning personally experimented with tricycles, bicycles, military grips, etc., and he felt they were okay. He could feel the enthusiasm of the factory for production.
But there is one regret, that is, Brazil cannot yet produce military three-wheeled motorcycles.
"Your Majesty, we do not have a mature motorcycle engine in Brazil. It will take a while to develop. This time is quite long, at least two years."
Mark expressed the technical difficulties to Tangning and told her that it would take time to solve them.
"As long as the engine problem is solved, we in Brazil can use motorcycles. If it is not solved, the motorcycle trailers produced will have hidden dangers."
"Well, is that so? It turns out it's an engine problem."
Tang Ning was also very quick in thinking and immediately thought of a solution. If he didn't have the technology, he would temporarily introduce advanced technology and let the factory learn and improve.
“In terms of motorcycles, it is more difficult for you to develop your own engine because your technical reserves are backward.
But this is not a problem. I will introduce some foreign technologies and personnel to improve you. In this process, you must be open-minded to learn and make progress.
We in Brazil can’t always rely on others for our engines, it’s better to have the ability to produce them ourselves. "
