The two-stage single-piston high-speed bullet launch system has the advantages that the pressure of the second air storing tank is increased according to the air adiabatic compression principle; the structure is similar to two single-stage pneumatic guns which are connected in series; the pressure of the air storing tanks is up to hundreds mpa, and therefore, the bullets can be quickly accelerated.
Description
Technical field
The invention belongs to a kind of fusion Pellet fueling field, be specifically related to a kind of two-stage list high speed piston Pellet Injection System.
Background technology
At present, lot of domestic and international fusion facility carries out Multi-pellet injection from feeble field side usually, adopt single-stage linear pattern pipeline transmission bullet, engineering is easier to realize.Multi-pellet injection speed is easier to reach 1km/s, and good integrality can be kept to be injected in plasma.But such initial velocity is nowhere near for the velocity of shot required by 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 kind of problem, the velocity of shot of theory calculate is up to several thousand metres/second.
Summary of the invention
The object of this invention is to provide a set of two-stage list piston emission system, provide a kind of High-velocity Projectiles to launch, realize bullet core fueling, thus improve Pellet fueling efficiency 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, first air accumulator is communicated with the second air accumulator, fast valve and piston is provided with successively in the second air accumulator, 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 reservoir pressure, and its structure is equivalent to the series connection of two single-stage pneumatic gun, and its reservoir pressure can up to hundreds of MPa, thus can ACCELERATING PROJECTILE rapidly.

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.
Detailed description of the invention
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, 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, is provided with fast valve 2 and piston 3, second air accumulator 4 successively and is communicated with acceleration gun barrel 6 in the second air accumulator 4, accelerates to lay bullet 5 in gun barrel 6.
The gas adiabatic compression principle that native system adopts improves the second reservoir pressure, its structure is equivalent to the series connection of two single-stage pneumatic gun, its reservoir pressure can up to hundreds of MPa, thus energy ACCELERATING PROJECTILE rapidly, emission process: according to time command, the first step opens fast valve, gases at high pressure in first air accumulator enter the second air accumulator instantaneously, piston advances forward in rapid promotion second air accumulator, compress the low-pressure gas in the second air accumulator, when pressure hundred MPa that the pressure sensor in air accumulator obtains, second step opens the second fast valve, now the instantaneous promotion bullet of gases at high pressure travels forward, accelerated in gun barrel, 3rd step, open vacuum-pumping system, extract excessive gas.
The operation of two-stage list piston emission system is as follows:
1, the first air accumulator volume is about 4L, 0.1MPa< pressure <0.5MPa, the high-purity helium of general employing;
2, the second air accumulator is about 1.2m, internal diameter 30mm, and volume is about 0.85L, is filled with helium in tank, pressure <0.11MPa;
3, piston adopts high-strength elastic rubber to make, and length is about 30mm, and overall tapered, be easy to high-speed slide, gross mass is about 30g, and the tolerance fit <0.01mm between the second air accumulator, ensures its sealing;
4, electron gun pipe range is about 1.2m, internal diameter 4mm, uses for ACCELERATING PROJECTILE.
5, the main equation of analog computation has: the conservation of mass of the first air accumulator and the second air accumulator and energy conservation equation, 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, above-mentioned 6 large equations separated by connection, can calculate the pressure in pellet injection process in each air accumulator and temperature rise; Piston displacement and speed; The acceleration of the back pressure that bullet bears and acquisition, speed etc.
