Abstract

The present invention relates to an axial compressor for aircraft engines that comprises at least two stages arranged in series. The compressor is fitted with a system for deactivating a portion of the stages, i.e. one or more of the last and/or front stages. This system is used for instantly modifying the compression stage in the compressor without modifying the number of revolutions of the rotor (1) thereof. The stage deactivation system consists in connection couplers of driving devices or in air bleed-off devices (5). The dimensions, the number and the arrangement of the bleed-off windows (5) are determined according to the optimal deactivation conditions of the stages. The free circulation of air between the opened bleed-off windows (5) and the annular chamber (6) depends on the compliance to the equation C1u = C2u in the impeller (2). The annular chamber (6) together with the compressor outlet are connected to the inlet of the combustion chamber (9) when the last stages are deactivated. When the front stages are deactivated, the annular chamber (6) surrounding the same is connected to the outlet into the atmosphere or to the compressor inlet. The opening of the bleed-off windows (5) corresponds to the deactivation of the stages. This invention can be used in both subsonic and supersonic engines.

Turning off the front steps to the sonic motors will allow you to receive the following technical results.

Each row of the blade 4, which is locked in the compressor, is interrupted by two fixed sequence of non-stationary devices in order to reduce the power consumption. The front steps of the compressor are equipped with air conditioning 5. The first step is connected to the complete sound from the bottom of the barrel. The koltsy side of the 6th round β is turnable χ steps is intended to be driven in χ and from the steps and transmitting it to turn 7, it is in parallel with the main. Tightening device 8 at the exit from the flight 6 is designed to remove the BOTH air inlet. There is no need for a permanent, non-existent material tape in the compartment where there is a gap in the cross section where it is not necessary. The size and quantity of the answers depend on the pressure in the unit 6 and make the difference in the case of the best possible exclusion of degrees. Squeezing β-related items can take out the situation outside of wheel 2, turning on the unit 4 and between the laptops. Also, the fan must be operated with air vents. The pressure switch in these valves is closed by valves controlled by hydraulic cylinders. The device of the air 5 is a medium for the exclusion of the other conditions in the compressor. The engine's exhaust air inlet must be connected taking into account * an additional air inlet due to the exhaustion of the air inlet 5. The process is connected to the shaft.

If the absolute speed rises, the value C - β ζ 'U * ”will be exited from the outlet; otherwise, the difference is neglected. C - the speed of the other working wheel; indices I and 2 mean the values of the parameters at the entrance and exit from the working wheel, respectively; β y - the angle between the external speed at the output \ Λ ^ and the operating angle of the koleea; ^ / - the angle between the direction of the external load at the inlet /, and /; C - the absolute speed at the entrance to the other forest. These meanings are also referred to in FIG. 4. In this case, the air supply has a pre-commissioned condition before working on the wheel. To remove the working load from the working range, the speed must be increased to a greater degree, as well as to the given angle β ζ СЦ - Сζи. • This is a result of the fact that there is a shutdown of the air inlet switch-off. and ^, are the angles between the direction of the absolute speed and the operating angle of the koleea, which is related to the entry and exit of the working forest. The Great Square η at the entrance to the city is © more This will ensure an increase in the absolute speed when the πβ movement is narrowed to the tapping channel for the sound flow. It should be taken into account when calculating the speed that the flow rate due to the narrowing of the flow channel cannot be higher than the critical one. The cleaning of the blade and the blade of the quick-disconnect device will not cause any noticeable hydraulic damage.

For example, switching off the power supply allows uninterrupted speeds of 5 to increase the speed of the fuel, and the speed of the power supply will increase the speed of operation. The growth rate of the restoration of home appliances is reduced. These motors are generally not regulated, therefore, depending on the speed of the vehicle, the vehicle is inactive for a short period of time. The written descriptions of the above are obvious, since there are many medications and variations of this invention.
