Thus, in a steam-water rocket engine, according to the Russian patent Me96104914, a source can be established according to the degree of increase in the efficiency of additional heating of the working fluid, performed in an engine characterized by the specific impulse of the thermal accumulator, which contains a backup pressure. Such a dependence is shown in Figure 3.5 of a substance with a high phase heat of the mentioned book by N.M. Belyaev and E.I. Uvarov. According to the transition and the heat capacity of the power shell, the increase in the specific impulse of the dog between the engine chamber and the nozzle and the combined pressure from 1250 to 1350 n.s./kg corresponds to the increase in the engine chamber by the supply regulator of the overheated temperature of the working fluid and the temperature of the engine water.

Additional patent Mo2154748 consists in the absence of heating, the electric heater is turned on after turning off the fuel before it is fed into the chamber of the thermal main heater or in the case of insufficient decomposition temperature, which reduces the efficiency of operation of the two-wheel engine heating from the main heater due to the reduction of specific thrust (or py- Nick The main electric heater is located on the volume of the pressure pulse). cups with perforated walls inside the ca- The basis of a useful model is the task of measuring the thermal decomposition of fuel.

This leads to a decrease in the heating and decomposition of fuel in the fuel supply area of the engine's efficiency, either due to the connection to the chamber, the connection of the bottom of the second cylinder to increase energy consumption, or due to the destruction of the housing through the perforated sleeve of the fuel temperature supply to entrance to the nozzle. fuel from the throttle into the internal body cavity; The second disadvantage is a large loss of electricity in the places of current leads to the main energy supplied to the engine due to the spiral electric heater radial radiation of thermal energy from the external holes in the cylindrical part of the housing and in both walls of the chamber into the surrounding space. This is due to the cylinder, hermetic welding along the periphery of both holes of the outer wall of the O-shaped cylinder from its outer surface in the surrounding wall of the second cylinder, hermetic welding of the walls - space. This is due to the supply of coolant from the second cylinder with the inner wall of the other fuel from the throttle into the gap between the outer walls of the cylinder; of the O-shaped and second cylinders, which excludes - execution in the inner wall of the second cylinder - heating of the outer surface of the case to a high temperature between the places of the current leads of the spiral from several temperatures. turns; 2. In the places of the current leads from the main spindle, the cylindrical tube of the thermal electric heater chamber for connecting the double heating and decomposition of the fuel and both cylinders to the power supply source is made in a cylindrical trench made of niobium alloy with a disilicide molybdenum part of the body and in both cylinders, radio coating (Mozig); holes, while on the periphery of the outer holes, the main spiral electronic wall of the O-shaped cylinder is hermetically sealed for the heater, the granules inside the cylinder tube are welded to the wall of the second cylinder, the wall of the drum and current leads is made of carbon-carbon composite the cylinder is hermetically welded to the internal material; wall of an O-shaped cylinder.

The execution of the additional heater as indicated and its efficiency in terms of specific gravity due to our excellent features significantly increases the efficiency of its operation due to two circumstances. differences from those indicated in the book by N.M. Belyaeva, E.I. First, the additional non-Uvarov fuel heater for hydrogen peroxide 8757C and hydrazine requires the supply of electrical energy to it, 10737C (page 92, table 3.1). since for heating and vaporizing the fuel, we will determine the value of the increase in specific thrust when the temperature increases using the energy of thermal radiation indicated by the temperature of the main electric heater. from 2.A1 of the specified book by N.M. Belyaeva, E.I. Uvarova. Practically all thermal radiation from the outer surface of the main spiral electric Wood ZM heater is absorbed by the inner wall of the cylinder, due to which it and the fuel de Nud. - specific thrust; are heated to a very high temperature. Thus, K is the coefficient of thrust of the nozzle; thus, almost all electrical energy, which is subject to Kr - constant consumption; is fed to the engine and is spent on fuel heating. Tk is the absolute temperature of the gas in front of the nozzle. This fact indicates a significant advantage of the breakthrough. of the new additional heater in comparison with According to this expression, all other things being equal, the prototype, which consists in the fact that the additional face of the specific thrust is directly proportional to the root of the heater for heating the fuel does not require electrical energy. nozzle Secondly, the loss of electrical energy, which is supplied to the engine, is excluded. In the case of using it as a fuel, the energy supplied to the engine is converted to hydrogen peroxide. , the type of the following technical results: 875:5273 1148 - the consumption of additional heating is excluded, i.e. 20,905. It is reduced by the same amount due to electric energy; fuel consumption - engine efficiency increases, 5. Execution of the main spiral electric heater, because the thermal energy of the main electric heater, the pellets inside the thermal heater chamber is not radiated by the engine body during the heating and decomposition of the fuel and current leads from the surrounding space, but with the help of additional carbon-carbon composite material, the heater and the performed in the second cylinder of the spiral, for example, of the UKPM-K brand, it is possible to increase them by almost 10095 is spent on fuel heating - the working temperature up to 25007С while maintaining va; strength and resistance to mechanical and thermal shocks - the energy characteristics of their loads are increased (see, for example, the book edited by Academician A.F.

The actual heating temperature of the fuel vapors before the nozzle, but the working temperature of the electric heater will be up to 14002С compared to the analog -10002С. slightly lower than the specified value, based on the tolerance of the main electric heater, the internal temperature of 14007С for the cylinder pipe of the auxiliary heater, as well as the granules in the thermal chamber of the thermal heating and fuel decomposition chamber, the liquid heating and fuel decomposition from both cylinders and current leads As a result, heat-resistant materials; increasing the working temperature of the spiral electric - increases the reliability of the supply of the electric heater and pellets inside the chamber of increasing energy to the main electric heater, the economy of the engine is ensured due to the fact that current leads are screwed into it to increase the specific thrust. | | carbon-carbon composite material with 6.

The essence of the intended useful model of 7. The design of the insulator between the cylinders is explained by the drawing of the engine. In general, the engine consists of a welded fuel core and a main spiral heater made of pus 1 with a thermal quartz fiber chamber located in it increases its vibration resistance and fuel heating and decomposition and additional heat resistance up to a temperature of 1600" 7C (|see, with a heater.
