March 7, morning, Maria Engineering Equipment Factory.
An engineering technician pulled out the lead, threw a grenade into the distance, and then quickly fell down.
3 seconds later, 35m away.
"Bang!"
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.
"Okay!"
Tangning praised loudly and clapped her hands in applause!
"Pa!" "Pa!" "Pa!"......
The king cheered and applauded, and of course his entourage also applauded.
Although this is flattering, the effect of the grenade explosion just now was really outstanding and convinced everyone.
This 09-1 wooden handle grenade is really powerful.
"Mark, you did a great job. The effect of the grenade you made 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 will complete the other two enhanced grenades as soon as possible."
Mark proudly puffed up his chest and said.
"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.
Dongfang Wooden Handle Type 67 Hand Grenades, Dongfang Wooden Handle Type 73 Hand Grenades, and Japanese Type 91 Hand Grenades are all simple and easy to make grenades, and there are not many technical problems.
Brazil’s current arsenal level is fully capable of designing and producing these three types of grenades, and they have indeed been produced now. The batch models are: Type 09-1 grenade, Type 09-2 grenade, and Type 09-3 grenade.
The Type 67 wooden-handled grenade was once a mass-produced weapon of the Eastern powers during the Cold War. The upgraded version of the original Type 61 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, 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 fired
.
Its main advantages are simple structure, low cost, and easy mass production; its disadvantages are that the mass of the whole bomb is too large, the volume is too large, and the number of fragments is small. Structural features: The firing mechanism of this grenade is added between the detonator and the detonator
A section of fuse is installed. One end of the fuse is engaged with the ignition tube 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. At the same time, production is strictly controlled.
process, thereby better solving the problems of early frying and susceptibility to moisture.
In addition to the functions of general grenades, the Type 73 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, 580 fragments, 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 fired
.
This grenade has a simple structure, low cost, and is easy to produce in large quantities. The body of the grenade is composed of explosives and 580 steel balls fixed in the upper and lower shells. The fuze is composed of a safety, a release safety mechanism and a collision mechanism. When the safety hoop is pulled off, it is thrown
Finally, the safety cover and sleeve slowly rise 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 the insurance and becomes ready to fire. When it hits the target, it completely tilts towards the body and the trigger is released.
Needle, trigger 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 a unified system that includes hand grenades, rifle grenades, and grenades/light mortars. This grenade
Can adapt 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 capacity 65g, detonation method 4~5 seconds burning fuze, delay time 7~8 seconds, 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 is ejected. 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 long time delay of 7 to 8 seconds before exploding. This feature allows the Type 91 to be used as a rifle grenade or as ammunition for the Type 89 grenade, because the longer fuse provides a longer flight time and can
Attack distant targets. When it is connected to the tail fin as a rifle grenade, or connected to the base containing the firing point and propellant as a mortar shell, the fuze will automatically activate because the firing pin will press against a weak spring due to the force of the launch.
, pressed into the interior. In addition, the Type 91 grenade can be used as a booby trap after removing the safety pin and placing it 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 for wooden handle 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 wooden-handled grenade 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 its function as a general grenade, it is also suitable for attacking high places, water surfaces, and mobile targets. This grenade is directly equipped with short-range support firepower for the regular army.
The Type 91 grenade is heavier at 530g, has average power, and has a long delay. However, 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 when equipped with regular troops.<

Maria Engineering Equipment Factory mainly produces basic military equipment.
In addition to the production of grenades, pistols, and pistol bullets, it mainly produces: motorcycles, military bicycles, military tricycles, ordnance mazaar, ordnance shovels, ordnance pickaxes, ordnance crowbars, ordnance wrenches...
Except for motorcycles, there is not much technical content in this area, but they have a characteristic, which is that 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.
In addition to the 1897 officer-type Mauser pistol and the 1898-type carbine imported from Germany, Tangning directly imported the M1907 fast pistol (M1932 quick-slow machine) that he had produced in the United States the year before last, in 1907.
P07 pistol (Walter P38), Walter PP pistol, PPK pistol, M1907 carbine (M1932 speed machine modification, 40-round ammunition capacity). There are also products such as 38 large-bar bicycles, self-propelled tricycles, 204-type army shovels, and 205-type engineers.
The design and construction plans for basic weapons and engineering tools such as shovels, Q1 wooden-handled folding shovels, 102-type small military picks, Q3-type three-folding shovels, etc. were prepared and let the Maria Engineer Equipment Factory in Brazil build production lines.
.
"The production of these engineering tools will be very helpful to our Brazilian soldiers at the bottom, but when will military three-wheel motorcycles be produced?"
Tangning personally experimented with the production of Mauser pistols in Brazil in 1897 officer type, 1898 carbine, M1907 fast pistol (M1932 speed machine), P07 pistol (Walter P38), Walter PP pistol, PPK pistol, M1907 carbine (M1932
The speed machine has been modified to hold 40 rounds of ammunition), a three-wheeled bicycle, a 38-wheel bicycle, a military gun, etc. It feels very good, and it allows him to feel the efforts of the industrial arsenal.
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 to be an engine problem."
Tang Ning's thinking was also very flexible, and she immediately thought of a solution. If she didn't have the technology, she would temporarily introduce advanced technology, and then let the factory learn and improve.
"In terms of motorcycles, it is more difficult for you to develop your own engine, and the 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.”
