Description

The invention relates to military equipment, and in particular to machines for special processing directed high-speed high-temperature gas flow of the outer surfaces of objects of equipment and weapons, buildings, roads, etc. during degassing, decontamination and disinfection, as well as for setting camouflage aerosol curtains and can be used in peacetime emergency situations.

A well-known stand-alone module of equipment for jet, thermal and thermochemical processing of objects (US Pat. RF No. 2166962, A 61 L 2/06, 09/27/1999), used for the degassing, decontamination and disinfection of equipment, structures, terrain gas, gas and gas and gas-vapor streams. The module is a platform on which a rotary table is movably mounted, which can be rotated in a horizontal plane by means of a hydromechanical drive. A gas generator based on a turbojet engine is installed on the rotary table on the frame. The frame of the gas generator contains a power casing mounted around the gas generator, and has the ability to deviate in a vertical plane. An operator’s cabin with controls and control over the operation of the module aggregates is also installed on the turntable with the possibility of horizontal rotation. The gas generator is equipped with a “steam” collector and a set of ejector attachments mounted on a jet nozzle. Depending on the design features of the prefixes, the parameters of the gas jet flowing from the gas generator are changed, with the possibility of forming gas, gas-droplet or gas-vapor flows. Units of all service systems (general fuel-hydraulic, air, electrical, and liquid chemical supply systems) operate autonomously by using the power of a turbojet engine (turbojet engine) of a gas generator, which makes it possible to use the equipment module both on a vehicle and on a stationary site. The listed features provide installation mobility and multifunctional application.

The disadvantages of this technical solution include the fact that it cannot be used for use in the combat zone or in the immediate vicinity of it due to the lack of reliable protection of the crew, the main components and mechanisms of the module from weapons, and also due to the lack of a system crew life support in the conditions of a high level of pollution (biological, chemical or radioactive) terrain.

Known universal generating installation of a heat gas stream, made on a basic tank chassis (US Pat. RF PM PM No. 39697, F 41 N 7/00, A 61 L 2/00, 60 K 3/04, 04/05/2004), adopted as a prototype.

This installation is made in the form of a module mounted on a turntable of the tank chassis. The module contains an armored housing in which a turbojet engine (TRJ) with a fuel system, a liquid system for supplying a working fluid to a heat gas stream, a mechanism for changing the angle of direction of a heat gas stream, and a number of other systems serving a turbojet are located. The module is mounted on a tank chassis while maintaining standard chassis systems. The armored module housing is mounted on a turntable. An opening for air intake is made in the bottom wall of the armored housing in order to organize external cooling blowing of the turbojet engine and its systems, and the front and rear walls of the housing are made with windows. The window in the front wall is made for the exit of the heat gas stream formed by the gas stream flowing from the turbojet engine and atomized (vaporized) working fluid, the window in the rear wall is made for intake of air supplying the turbojet engine. The window in the front wall performs, in addition to the above, the function of an ejection device, which reduces the pressure inside the armored housing and helps to draw air from the opening in the bottom wall, for cooling blowing of the turbojet engine. The operator’s cab in the installation is connected to the turntable and is housed in the tank chassis. The installation is equipped with a fire extinguishing system, and the tank chassis has life support systems (filter ventilation installation, radiation protection), which are necessary for operation in conditions of damaging pollution. The use of a basic tank chassis in a well-known installation with the preservation of its regular systems and the placement of turbojet engines with its maintenance systems in an armored corps ensures high throughput and maneuverability of the installation and allows its use as part of a military unit directly in the combat area, and the placement of the operator’s commander’s cabin the chassis of the chassis provides protection of the workplace of the commander-operator from weapons and life support of the crew in conditions of a high level of pollution (biol cal, chemical or radioactive) areas.

However, this installation has several disadvantages identified as a result of experimental testing. Such disadvantages include the fact that

- the design of the armored hull does not have sufficient rigidity and therefore, when moving the generating unit mounted on the chassis of the tank over rough terrain, it experiences significant loads that can lead to distortion;

- access to the turbojet engine and to the systems and units serving it located in the armored housing is difficult;

- the possibility of replacing the turbojet engine without dismantling the armored housing is not provided;

- the design of the armored hull makes it difficult for the operator commander to land through the hatch located on the turntable;

- Difficult all-round view of the terrain from the commander of the operator;

- the impossibility of the regular location of the antenna input of communications. This is due to the fact that there is no device on the tank chassis for installing an antenna input for radio communication. In this case, the antenna should be positioned so that the shielding properties of the armored housing do not affect the stability of radio communications.

The problem to which the present invention is directed, is to create a universal generating installation of heat gas flow on a basic tank chassis, which has the ease of operation and maintenance of turbofan engines and all its systems while maintaining security at the tank level.
