Description

The present invention relates to rocket technology and can be used in the preparation of rocket fuel components, the propulsion of which operate on high-boiling components.

Closest to the proposed invention is a launch complex for prelaunch preparation and launch of a launch vehicle with a space warhead (options), containing liquid rocket fuel storage facilities, facilities for refueling and draining liquid rocket fuel components (patent number RU 2318706 C1, B64G 5/00 March 10, 2008).

The proposed method of preparing fuel components (CT) for refueling propulsion systems of rocket technology includes the process of temperature control and gas saturation of fuel components, while the process of temperature control and gas saturation is carried out in a temperature control and saturation unit (ATN) using a filling tanker (ZAC) and auxiliary equipment by pumping components closed loop fuel: refueling tanker - thermostat and saturation unit - refueling tanker.

The essence (task) of the method is to provide the specified temperature and gas saturation parameters of the fuel components by pumping them through the thermostatic and saturation unit.

The invention is illustrated by the "Preparation Scheme" (Fig. 1) and the "Schematic diagram of ATN" (Fig. 2).

The unit for temperature control and saturation is a transportable box body with technological equipment and controls placed in it.

As controls are used - a power board, a control panel, a pneumatic shield.

As technological equipment, a drain tank (pos. 9), a jet pump (pos. 12), an electric pump unit (pos. 5), heat exchangers T1 (pos. 6) and T2 (pos. 11) are used. All technological equipment is interconnected by pipelines (pos. 7) with shutoff valves (pos. 10).

The coolant from the refrigeration-heating center (KhNC) (pos. 1) is fed to the input of the thermostat and saturation unit (ATN) (pos. 2), passes through heat exchangers T1 and T2 (pos. 6 and 11) and returns to the KhNTS (pos. one).

The fuel components from the refueling tanker (ZAC) (pos. 3) are fed to the ATN input (pos. 2), where they are pumped through heat exchangers T1 and T2 (pos. 6, 11) with the help of an electric pump unit (pos. 5), in which either heating them or cooling them. After the heat exchanger T2 (pos. 11), the fuel components enter the jet pump (pos. 12), where they are saturated with gas in one of two ways:

- the supply of nitrogen from the container (pos. 8) into the component stream;

- ejection of nitrogen from the nitrogen pad ZAC.

Heated (chilled) and gas-saturated fuel components are returned to the ZAC (item 3).

After completion of the thermostating and gas saturation operations, the remaining components of the fuel from the heat exchangers T1 and T2 (pos. 6, 11) are squeezed out by nitrogen coming from the cylinder (pos. 8) into the drain tank (pos. 9), from where they are delivered to the filling station via a separate pipeline line.

Vapors of fuel components from the thermostat and saturation unit (pos. 2) enter the unit for thermal neutralization of vapors of fuel components (pos. 4), in which they are burned.

Thus, we see that the technological equipment provides thermostating of the fuel components passing through the unit’s heat exchangers (the heat carrier is supplied to the heat exchangers from an external cooling and heating center) and gas saturation of the fuel components in one of two ways:

- by supplying nitrogen directly to the liquid stream;

- due to the ejection of nitrogen from the nitrogen pad of the ZAC tank, in which the prepared fuel component is located using the jet pump of the thermostating and saturation unit while maintaining the corresponding pressure in the nitrogen pad of the tank.

In the process of preparation, the fuel components are pumped in a closed loop: refueling tank truck - thermostat and saturation unit - refueling tank truck until the required temperature and gas saturation parameters are reached.

The refueling tank truck is a mobile unit that provides transportation and temporary storage of fuel components.

As auxiliary equipment are used:

- a cooling and heating center that provides cooling and / or heating of the heat carrier and its supply with a given flow rate to the heat exchangers of the thermostatic and saturation unit (ATH).

- a unit for thermal neutralization of vapors of fuel components, in which vapors of fuel components formed during the technological process are burned.

In the process of work carried out on the subject of JSC VPK NPO Mashinostroyeniya (topic “Strela-S”), a comparative analysis of the proposed method for the preparation of rocket fuel components and currently used.

The following was revealed:

Thus, the proposed method for the preparation of rocket fuel components, which provides the temperature and gas saturation parameters of the fuel components by pumping them through a thermostat and saturation unit and a tanker, is more mobile, easy to use, convenient to use, less costly and more environmentally friendly.
