The shock-wave propulsion of rectilinear motion

Abstract

A shock-wave propulsion system for rectilinear motion moves space objects in zero gravity. The shock-wave propulsion system comprises: a liquid-propellant supply system (3) with control-operated valves connected to at least two hollow pipes (2) near their plugged ends; in-pipe heaters (4) that generate high-pressure gas, producing a transient uncompensated impulse; shock-wave dampers (5) mounted on the opposite open pipe (2) ends; a liquefaction system (6) coupled to the open ends to condense the gas; and a return -pumping circuit (7) that feeds the condensed liquid as a propellant back to the liquid-propellant supply system (3). In addition, the above valves controlled by the control system (8) are designed to start each subsequent pipe (2) so that its filling with liquid working fluid begins simultaneously with shutting off the previous pipe (2) after the wave reaches its shock-wave damper (5), creating repeated thrust cycles.

Description

[0001] THE SHOCK-WAVE PROPULSION OF RECTILINEAR MOTION

[0002] The shock-wave propulsion of rectilinear motion (SWP, propulsion, system) refers to space technology (G03H 99 / 00; B64G 1 / 28) and can be used as a power drive for moving space objects in weightlessness.

[0003] There are no analogues of mechanical devices whose action in weightlessness can correspond to SWP.

[0004] The purpose of the invention is to expand the range of mechanical means suitable for working in weightlessness, along with the use of rocket engines.

[0005] To ensure the motion of the system, sequential, with a time delay, supply of the liquid working body into the hollow pipes, in a quantity no less than two, near the plugged ends of these pipes, followed by its transformation into a gas with high pressure and maintenance of this pressure during the working cycle, which ensures the occurrence of force on the plugged ends of the pipes with the formation of an impulse of the main part of the system, is used to ensure the motion of the system. At the opposite free ends of the pipes, shock wave extinguishers are installed, after which the working body enters the liquefaction. After liquefaction, the working body is pumped back by the pump for further supplying into the pipes. In the pipes, in which the shock wave has reached the shock wave damper, the supply of the working body is stopped, and they are freed from the excess of the working body before the start of a new cycle.

[0006] An example of a block diagram of a shock-wave propulsion using three pipes is shown in Fig. 1.

[0007] The SWP consists of a body 1, to which all further elements of the propulsion are attached, a certain number of pipes 2, which are made in the form of a hollow pipe, one of the ends of which is plugged and has a liquid working body supply system to maintain high pressure in the pipe during the work cycle, 3 the gasification system of the working body (heater) 4, shock wave extinguishers are installed near unblocked ends the other pipes 5, the liquefaction system of the working body 6, to which the pipes are connected 2, after the shock wave extinguishers 5, the system of return pumping of the working body 7, the control system 8, which with the help of the supply system 3, connects each subsequent pipe 2 to work with a time delay calculated in such a way that the last working pipe is turned on at the same time as the first pipe is turned off, the power system 9, the system of refueling and storage of the working body 10.

[0008] The propulsion due to a temporarily uncompensated impulse that occurs in the system before its operation is completed.

[0009] A peculiarity of the shock-wave propulsion of rectilinear motion is its property, being in weightlessness, due to a temporarily uncompensated impulse, to bring itself into translational motion or to end it.

[0010] The possibility of motion of the shock wave propulsion is based on two phenomena:

[0011] The difference in time that exists in a closed mechanical system between the occurrence of an impulse of its main part during the mutual rectilinear movement of the system elements and the time of its compensation.

[0012] Differences between the impulse occurring in the main part of the system during the execution of the working cycle and the impulse arising during the reverse pumping of the working body, due to the fact that part of the impulse during the execution of the working cycle is transmitted directly by the shock wave without transferring the mass of the working body.
