Emergency and rescue means airplanes

 

For quick and safe descent to land passengers in the event of an emergency landing on unequipped area or emergency situation on the ground in the civil aviation aircraft with high location of the fuselage used inflatable evacuation slides TH-2 (Tu-104A, Tu-104B, Il 62, 154-Tu), TN-3 (IL-18, Tu-134), TN-5 (Tu-114 aircraft). Inflatable slides are placed on a plane near the front doors.

Inflatable gangway is a trough consisting of two longitudinal inflatable "beams", interconnected by transverse cylinders. The free space between the longitudinal "beams" and the transverse cylinders is closed with a rubberized fabric pasted on them. Thus, a rather hard tray is produced, along which the sliding descent of passengers and crew is made. In the upper part of the longitudinal "beams" are glued circular chambers, which serve as handrails when entering the ladder, and three inflatable chambers are pasted into the upper part of the transverse cylinder, forming the threshold of the ladder and thereby protecting passengers from bruises from the threshold of the doorway. To the ladder are attached twostrap with lugs (brackets), which gangway is fixed under the threshold of the doorway of the aircraft.

Inflatable evacuation slides depending on the type (TN-2, TN-3, TN-5) have different lengths in the operative position (from 4250 7760 to mm) and are filled with carbon dioxide from cylinders 8 liters capacity. Sealed inflatable slides allows you to use them within 30 minutes, after which the ladder gradually loses! rigidity. The weight of the ladder in a case (without cylinder and hoses) from 20 (TN-3) to 30 kg (TN-5). The weight of one cylinder filledcarbon dioxide is 16 kg, including carbon dioxide by weight5 kg. Maximum pressure in the ladder bar 0,45, the filling ramp 20-25 seconds. Packing Case ladder is fastened by means of pins and tapered pins (for parachute packing type), it has an additional lacing for utjazhki ladder in a case in the package.

Inflatable emergency ladder greatly speeds up the evacuation of passengers from the aircraft in case of emergency. Available on airplanes cloth trough also serve for the rapid evacuation of passengers from the aircraft. In the presence of inflatable evacuation slides on the Tu-114 rescue chute cloth used as a redundant means of salvation. Tu-Tu-104 and 124 rescue chute fabric are the main means of rapid evacuation of passengers to the ground.

The application of the aviation rescue inflatable ladder and rescue chute is given in the figures, diagrams and special instructions.

Using inflatable ladder TN:

  • 1. Gangway, packed in a carrying case, put on the threshold of the doorway.
  • 2. Attach straps tips the ladder in a doorway threshold nodes and push the ladder to the outside cover.
  • 3. Pull the rope stud pins of the cover, then the case will be revealed, and the ramp will be thrown out on the ground.
  • 4. Turn the cylinder valve handle. Trap filled with gas.
  • 5. Go down the ladder odnomu- two crew members and passengers to insure on the ground at a gathering of the ladder.

If a strong crosswind one or two crew members descend on a rope from the bosses (nodes) to the ground and pulled the bottom of the stairs from the plane during filling, preventing the demolition of the ramp under the plane.

To ensure the rescue of passengers and crew in the event of a forced landing on water in civil aviation are provided individual and group boats.

For individual flotation devices are lifejackets HOAs-63P, which are designed to maintain a person afloat after leaving the aircraft and before landing it on a group boat (inflatable aviation life rafts), or other means of salvation (boats, boats, boats, passing ships, helicopters, etc. . P.).

Vest HOAs-63P

Vest HOAs-63P

The waistcoat ASJ-63P has the form of a breastplate, consists of two inflatable chambers and is filled with gaseous carbon dioxide from a balloon. A waistcoat is put on the neck through the hole and fixed on the belt with the help of a nylon braid. The weight of the vest is 950 G. The vest material is a two-layer rubberized fabric of yellow color. Filling with carbon dioxide takes place over 5-7 sec. To inflate the waistcoat, the mouth has two tubes with mouthpieces and valves. The waistcoat has a signaling equipment - a warning light, powered by a battery with a water feature, and a signal whistle for signaling in the dark and fog. To bring the battery cell into action, it is necessary to pull out the plugs covering the holes in the battery in the water. Regardless of the condition of the person in the water, the vest supports him face up. The waistcoat allows you to turn over on your chest and swim in any way, if necessary. The waistcoat ASJ-63P can support two people afloat. One person wearing a waistcoat will be able to keep afloat another person without a lifejacket.

liferaft

It includes a group floating craft inflatable liferafts SP-12, 10-PSN, PSN-in calculated respectively 12,10, 6 people. Capacity rafts SP-12, PSN-10, 6-PSN, respectively equal to 1300, 1400, 1000 kg. Weight rafts SP-12, 10-PSP, PSN-6, manned equipment, respectively, equal to 65, 70,47 kg. Made life rafts from two- and three-layer ^ diagonalno- duplicated rubberized fabric of orange and yellow. Rules rafts to bring to the working position and use them applied to the outer shell of the raft and the raft on the inside the tent, as well as special instructions. Currently LAS 5M-2 Boat universally replaced -naduvnymi rafts with awning.

 

 

ACCOMMODATION rescue means on an airplane when flying over water

In accordance with the domestic and foreign practice, the development and application of aircraft rescue means civil aircraft when flying over water have life jackets for each passenger and crew member on board the aircraft are located so that each passenger and crew member can easily get it out of his seat. Typically, aviation life vests are located under the seats near the passenger seats and jobs crew, including flight attendants.

All aircraft when flying over water at a distance from the coast, in addition to life jackets or equivalent devices have on board liferafts sufficient to accommodate all persons on board the aircraft. Liferafts are arranged so as to provide free access to them in case of an accident.

Rafts have rescue equipment (power tools and equipment for pyrotechnic distress signals: rocket, Pyrocartridges day and night, etc...).

Also rafts on board the aircraft when flying at a great distance from the coast, there are radio transmitters, impervious to water, netonuschie and easy-to-use out of the aircraft by persons who do not have skills. Life rafts and jackets are equipped with electric lights,

to facilitate detection of the accident victims. Life rafts and emergency radio transmitters are placed near the exits and emergency (emergency) hatches of the aircraft at the sites of attachment are placed in special compartments occupying the top lobbies and passenger compartments, or compartments, located in the wing.
