Description
Technical field
The invention belongs to the reinforced field of a kind of fusion bullet, be specifically related to a kind of two-stage list high speed piston Pellet Injection System.
Background technology
At present, on lot of domestic and international fusion facility, conventionally from feeble field side, carry out bullet injection, adopt single-stage linear pattern pipeline transmission bullet, in engineering, be easier to realize.Bullet injection rate is easier to reach 1km/s, and can keep good integrality to be injected in plasma.But such initial velocity is nowhere near for the desired velocity of shot of large-scale fusion reactor core fueling, in order to break through the speed limit of single-stage Pneumatic acceleration, be necessary to design a kind of High-velocity Projectiles emission system, and adopting two-stage list piston emission system can solve this class problem, the theoretical velocity of shot calculating is up to thousands of metre per second (m/s)s.
Summary of the invention
The object of this invention is to provide a set of two-stage list piston emission system, a kind of High-velocity Projectiles transmitting is provided, realize bullet core fueling, thereby improve the reinforced efficiency of bullet etc.
The present invention realizes like this, two-stage list high speed piston Pellet Injection System, it comprises the first air accumulator, the second air accumulator, piston, fast valve, accelerates gun barrel, the first air accumulator is communicated with the second air accumulator, in the second air accumulator, be provided with successively fast valve and piston, the second air accumulator is communicated with acceleration gun barrel, accelerates to lay bullet in gun barrel.
Advantage of the present invention is, the gas adiabatic compression principle that its adopts improves the second air accumulator pressure, and its structure is equivalent to the series connection of two single-stage pneumatic gun, and its air accumulator pressure can be up to hundreds of MPas, thus ACCELERATING PROJECTILE rapidly.
Accompanying drawing explanation
Fig. 1 is two-stage list high speed piston Pellet Injection System structural representation provided by the present invention;
Fig. 2 is schematic diagram before pellet injection;
Fig. 3 is schematic diagram after pellet injection.
In figure, 1 first air accumulator, 2 fast valves, 3 pistons, 4 second air accumulators, 5 bullets, 6 accelerate gun barrel, 7 hydrogen or helium.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail:
Two-stage list high speed piston Pellet Injection System mainly comprises the first air accumulator 1, the second air accumulator 4, piston 3, fast valve 2, accelerates gun barrel 6.
As shown in Figure 1, the first air accumulator 1 is communicated with the second air accumulator 4, fast valve 2 and piston 3, the second air accumulators 4 is installed successively in the second air accumulator 4 and is communicated with acceleration gun barrel 6, accelerates to lay bullet 5 in gun barrel 6.
The gas adiabatic compression principle that native system adopts improves the second air accumulator pressure, its structure is equivalent to the series connection of two single-stage pneumatic gun, its air accumulator pressure can be up to hundreds of MPas, thereby energy is ACCELERATING PROJECTILE rapidly, emission process: according to time command, the first step is opened fast valve, gases at high pressure moment in the first air accumulator enters the second air accumulator, promote rapidly the piston advances forward in the second air accumulator, compress the low-pressure gas in the second air accumulator, during pressure hundred MPa that the pressure sensor in air accumulator obtains, second step is opened the second fast valve, now the instantaneous promotion bullet of gases at high pressure travels forward, accelerated in gun barrel, the 3rd step, open vacuum-pumping system, extract unnecessary gas.
The operation of two-stage list piston emission system is as follows:
1, the about 4L of the first air accumulator volume, 0.1MPa< pressure <0.5MPa, generally adopts high-purity helium;
2, the second air accumulator is about 1.2m, internal diameter 30mm, and the about 0.85L of volume, is filled with helium in tank, pressure <0.11MPa;
3, piston adopts high-strength elastic rubber to make, and the about 30mm of length is whole tapered, is easy to high-speed slide, and the about 30g of gross mass, and the tolerance fit <0.01mm between the second air accumulator, guarantee its sealing;
4, the about 1.2m of electron gun pipe range, internal diameter 4mm, is used for ACCELERATING PROJECTILE.
5, the main equation of analog computation has: the conservation of mass and the energy conservation equation of the first air accumulator and the second air accumulator, the equation of momentum of piston, characteristic of fluid line equation in the second air accumulator, bullet back pressure equation and the equation of momentum.
6, connection is separated above-mentioned 6 large equations, can calculate the pressure in each air accumulator and temperature rise in pellet injection process; Piston displacement and speed; The back pressure that bullet bears and the acceleration of acquisition, speed etc.
