What Is the Foramen of Monro?

The Monroe effect is also called the concentrated effect. English name: Gathering energy effect (Munroe effect) is derived from the law discovered by Charles E. Munroe, an American in 1888, in an explosive test. That is, after the explosive explodes, the explosive products are scattered outward along the normal direction of the explosive surface under high temperature and pressure. Therefore, after the detonation of the grooved charge, a condensed stream of explosive products with a high speed and pressure will appear on the groove axis, and the chemical energy released by the explosive explosion will be concentrated within a certain range. .

The so-called "

When the inner surface of the charging groove is lined with a medicine-shaped cover, the charging

It can be roughly divided into: large cone angle type, small cone angle type, horn type, composite type, hemisphere type and so on. The following data is based on a certain amount of RDX charge. You can use it as a reference to compare the performance of various drug masks. (Different types and quantities of medicines will have different test results, so the following data tables are not accurate data, and can only be used as a reference for the comparison of the performance of different shape medicine caps)

Monroe effect

The best application of the Monroe effect is to deal with armored vehicles and tanks with steel plate protection, so hollow armored armor-piercing ammunition was produced. Later, in experiments, it was found that if a thin layer of metal (such as copper) is added to the hollow portion of the armor-piercing projectile, the power of armor-piercing can be greatly increased, because the original armor-piercing entity was the detonation product of the explosive explosion Is a strong stream of high temperature and high pressure. After the metal hood is installed, the high temperature generated by the explosion first destroys the metal, and then the high-speed air stream follows the Monroe effect to compress these pressed metals to the center and press the High speed launch. These objects moving at high temperature (above 1000 ° C) and high pressure (above 1 million atmospheres) at high speed (about 8000 to 9000 meters per second) are called metal jets, which replace the original simple detonating airflow, greatly strengthening the heavy Armor penetration capability ^[1] .
