Teoretical engineering

Teoretical engineering     Ballistic missiles use either 1. liquid fuel and an oxidizer, or 2. a solid fuel-oxidizer mixture. 1. Liquid fuels and oxidizers are very energy efficient. But they are explosive. There have been many severe liquid ballistic missile accidents in history.   2. Rockets with a solid mixture of fuel-oxidizer are large, but much safer, they have a simpler design, but it is difficult to reduce or increase engine thrust.   3. A ballistic missile with solid propellant and liquid oxidizer can be very safe. In the event of an accident, a fire may occur, a gift, but not an explosion, because fuel and oxidizer cannot mix at once. The solid propellant can be positioned in the same way as in solid propellant rockets, and the oxidizer must be sprayed through the nozzles. This makes it easy to adjust the engine power. As fuel in such a rocket, a substance with a higher density can be used than in rockets with a solid fuel-oxidizer mixture. For example, fuels with a

Rescue engineering This is a very small device OFLAMERON the size of a plastic water bottle and weighing 1-1.5 kilograms.  Such a device can be made in thousands of factories around the world and it will cost $ 20-30   Any naval pilot or sailor can have this device because it can protect it from cold water not for 24 hours, like a wetsuit, but for 3-4 days. And it will help keep you warm even if you don't have a wetsuit at all.   This device can be used by travelers, training or military personnel in the Arctic. If the situation becomes critical, this device will not let you freeze for 2-3 days, even in very severe frosts. The device can be easily adapted to protect against polar bears.    Rescue engineering

Rescue engineering On April 7, 1989, the Soviet nuclear submarine K-278 "Komsomolets" sank in the Norwegian Sea as a result of a fire. 42 people were killed, 27 crew members were rescued.     The sailors found themselves in icy water. The rescue ships were able to arrive at the scene of the accident only many hours later. Modern wetsuits are kept in cold water for 6-8 hours. If a storm, current or wind carries the sailor away from the accident site, the time of his search is greatly increased.    The OFLAMERON device can multiply the protection of a standard wetsuit. A person in icy sea water can stay alive for several days. This device is very compact, cheap and very simple in design. The device does not interfere with crawling through the hatches, can be used with standard wetsuits and can be used already in the water. Military pilots and sailors will feel much more confident on missions. In civil aviation, shipping and on drilling platforms, this will be the stronge

During the rescue operation, it became known about four dead. As of 17:00 Moscow time, six crew members have already been rescued. The rescue operation at sea was suspended due to high waves, but work from the air with the help of helicopters is still ongoing, TASS reports, citing local authorities.     The ship sank in the Inkumu area (Bartin province) on Sunday afternoon. According to local authorities, there were 12 Ukrainian citizens on board (at first, information about 13 crew members also appeared). However, according to Rosmorrechflot, there were a total of 12 crew members on board, and two of them were Russians. Diplomats in Russia and Ankara are still investigating the details of the incident. Poor weather conditions are said t

What happened then is described in a number of sources. We will rely on the article of the now deceased D.I. n. A. Orlova "US aerial reconnaissance over the territory of the USSR in 1950-55." - this is not popular literature, but a publication in the authoritative scientific journal "New and Contemporary History" (No. 6, 2000). The author drew on materials published in the Russian press and his own archival finds. One of the main documents is a report to the unit commander, Colonel F.

Rescue engineering Dry cargo ship "Anda" capsized in neutral waters near Sevastopol due to a storm. The ship, flying the flag of Togo, reportedly carried wheat. Onboard there was a crew of nine people - three Indian citizens and six Syrians. RIA Novosti: https://crimea.ria.ru/society/20170729/1111353026.html The rescue operation lasted from 8 am to 11 am. Eight rescued sailors were taken aboard the cargo ship (bulk carrier) Minoan Grace, which was heading for Turkey and came to the aid of the sinking bulk carrier.   "The first three crew members were found at the crash site at 8.15, then at 9.35 another sailor was rescued and found on the raft. At 10.35, four more people were found in the water," the press service of the Ministry of Emergency Situations said All those rescued were wearing vests. The fate of the only sailor who was without a vest remains unknown. His search continues. The operation is hampered by severe weather conditions. In the search area, a
