With the acceleration of national defense modernization, the understanding of scientific research on man, machine and environment, and the emergency oxygen supply of various equipment and machinery (such as aircraft, tanks and submarines) have attracted the attention of military management departments. For example, when the submarine dives to a certain water level, the cabin is completely isolated from the outside world, and the oxygen supply of the personnel in the cabin will become an extremely important issue. After field test, the cabin capacity in the closed cabin exceeds 10 passengers. After about half an hour, the oxygen concentration will drop below 20% or lower. If oxygen is not replenished in time, the combat effectiveness of soldiers will be greatly affected. According to relevant information, it is reported that this plane with about 200 people will have an oxygen supply device for half an hour. If you use a high-pressure oxygen cylinder with more than 6000 liters of oxygen, its weight will reach several hundred kilograms. The solid oxygen supply device with the same oxygen supply capacity weighs about 40 kg. Therefore, if the solid oxygen supply device is configured, the load of these mechanized equipment will be greatly reduced. Especially in an emergency, even if the machinery is paralyzed, the oxygen supply will not be affected.
There are also reports on the application of solid oxygen in some common equipment abroad, such as parachute oxygen supply, navy life jacket inflation and personnel oxygen supply, first aid kit emergency oxygen supply, battlefield rescue mobile oxygen supply and so on.
Solid oxygen will be more and more widely used in national defense and military equipment (including plateau stations, mine self-rescue and battlefield rescue).
China's basic research and application development in this field has a history of several decades, and it is in the leading position in the world in many aspects. With the further opening of China's national defense science and technology industry, military equipment contracting qualification and military equipment procurement, it has created very good conditions for some advanced scientific research achievements and technologies of local enterprises and institutions to enter the military equipment construction.
