Colloidal silicon dioxide is a form of silicon dioxide. In colloidal form, it is used in medicine as an enterosorbent (Asorb, Alesorb, Alfasorb, Novosorb, Polysorb, Sorboxan) and externally for purulent-inflammatory diseases of soft tissues (purulent wounds, phlegmon, abscess, mastitis). In addition, due to the high level of safety in many countries of Europe and Asia, enterosorbents based on silicon dioxide are presented in the form of dietary (food) supplements and can be sold outside pharmacies.

The sorption surface of enterosorbents based on colloidal silicon dioxide is in the range of 300-400 m² per 1 g of the main substance.

The MiG-29 is designed to destroy all types of air targets with guided missiles and airborne cannon fire in simple and difficult weather conditions in free space and against the background of the earth, including in conditions of interference, as well as to destroy ground targets using unguided weapons in conditions visual visibility.

The first flight of a prototype of the MiG-29 fighter was made on October 6, 1977 by the Soviet test pilot A. V. Fedotov.

The giant An-22 military transport aircraft was named "Antey" in honor of the invincible giant from Greek mythology - Antey. Antaeus was the son of the earth goddess Gaia and could endlessly receive new strength from contact with the earth and therefore never got tired. However, the name "Antey" for the plane is not very suitable, because when Hercules fought the giant Antey and tore him off the ground, lifting him high into the air, Antey's strength quickly dried up. Thanks to this, Hercules was able to kill him. The ambiguity of this situation also lay in the fact that the Greek name Hercules or Hercules - in the ancient Roman adaptation - the name given to the American military transport aircraft Lockheed C-130 Hercules.

An-72 (according to NATO codification: Coaler - “Coal Miner”, popular nicknames: “Cheburashka”) is a Soviet multi-purpose transport aircraft. Developed in the Design Bureau named after O.K. Antonov to replace the An-26 aircraft.

It has been in service with the Aerospace Forces of Russia and a number of other states of the world for almost 40 years (and it has no equal in terms of the volume of tasks performed). The operation of the An-72 in various modifications continues to this day[when?][2]. The multi-purpose An-72 holds the record among transport aircraft in terms of flight altitude.

Based on the An-72, the An-74 multi-purpose transport aircraft was created, featuring a slightly elongated wing, a separate navigator's workplace, a more powerful TA-12 APU, and so on, later the family developed into the An-148 passenger aircraft.

Mi-26 (product "90", according to NATO codification: Halo) is a Soviet and Russian heavy multi-purpose transport helicopter. The world's largest mass-produced transport helicopter. Produced at the Rostvertol plant of the Russian Helicopters holding.

General information

The Mi-26 helicopter is designed for flights in various physical and geographical conditions according to the rules of visual and instrumental flights day and night, on equipped and non-instrumented routes and routes off-piste and on non-orientated terrain, both from equipped and non-equipped sites (heliports).

The helicopter is built according to the classical scheme with an eight-blade main rotor and a five-blade tail rotor, a three-post fixed landing gear. The helicopter's power plant includes two D-136 turboshaft engines and a TA-8 auxiliary power unit. The design of the helicopter is made of aluminum-lithium alloys with a wide use of titanium alloys and composite materials.

Su-25 (product "T-8", according to NATO codification: Frogfoot - "frog's paw") - Soviet attack aircraft, armored subsonic military aircraft.

The attack aircraft is designed for direct support of ground forces over the battlefield day and night with a direct line of sight to the target, as well as the destruction of objects with given coordinates around the clock in any weather conditions. The Su-25 first took to the air on February 22, 1975. Aircraft of this type have been in operation since 1981, have taken part in many military conflicts and will remain in service with the Russian Air Force until at least 2020. On October 8, 2009, the Ministry of Defense of the Russian Federation announced the resumption of purchases of attack aircraft of this type for the Russian Air Force.

Mi-28N "Night Hunter" (according to NATO codification: Havoc - "Devastator") is a Soviet and Russian attack helicopter manufactured by Rostvertol PJSC, part of the Russian Helicopters holding, designed to search and destroy in conditions of active fire opposition from tanks and other armored vehicles, as well as low-speed air targets and enemy manpower.

Russian stamp, 1997 Mi-28.

The Mi-28 is capable of performing aerobatics: Nesterov's loop, Immelman's roll, roll, sideways flight, backward flight, sideways flight at speeds up to 100 km/h, turns at an angular velocity of up to 117 degrees/s, and a maximum roll rate of over 100 deg/s. c.
