Description
Technical field
The invention belongs to gasifier section technical fields, and in particular to the gasifier section that one kind can quick start.
Background technique
Big gun formula ignition start is that the direct impulse turbine blade of combustion gas generated with gasifier section generates torque band turn
Son is turned in journey in band and is lighted a fire with ignition start engine.For the reliable starting for improving engine, the existing and following turbo blade
The demand of gasifier section can be proposed in class reseach of engine, therefore the fast starting of gasifier section is that one item is crucial
Technology.
As used tail portion ignition start in existing gasifier section, this igniting pattern advantage is that energy used is smaller,
And output energy is larger, but the disadvantage is that lights the high-temperature ignition combustion-gas flow of powder charge under the premise of heat exchange is still insufficient i.e.
Gasifier section can be caused to fail normal output services, fast starting failure from nozzle position quick pressure releasing.
Summary of the invention
In view of this, increasing ignition flame conduction the present invention provides the gasifier section that one kind can quick start
Length, shorten ignition delay time, can quick start.
The present invention is achieved through the following technical solutions:
A kind of gasifier section quick started, comprising: medicine box shell, ignition charge, drug blocking, diaphragm seal, burning
Room housing and solid propellant；
The medicine box shell is the toroidal shell with centre bore and the toroidal cavity coaxial with centre bore, toroidal shell
Extend coaxial annular convex platform in one end face；The both ends of the surface of toroidal shell are respectively equipped with to be communicated with its internal toroidal cavity
Annular through-hole；Ignition charge is installed in the toroidal cavity of medicine box shell, is used for igniting solid propellant；Drug blocking is mounted on medicine
In the toroidal cavity of box shell, and the annular through-hole of medicine box shell left end is closed, drug blocking uses combustible material；Diaphragm seal
It is mounted on the right side of medicine box shell, and the annular through-hole of medicine box shell right end is closed；
The burning chamber shell is tubular construction closed at one end open at one end, the convex annular of open end and medicine box shell
The end face docking at end where platform；The solid propellant of tubular structure is coaxially mounted in combustion chamber shell body, and its end face and medicine box
There are setting gap, inner peripheral surfaces to be located at outside the annular convex platform of medicine box shell for shell end face.
It further, further include damping ring, enabling the periphery of the toroidal cavity diameter maximum of medicine box shell is big circumference
Face；Damping ring is sleeved on the great circle circumferential surface of the toroidal cavity of medicine box shell.
Further, extend in the middle part of the other end of medicine box shell internal diameter it is identical with the internal diameter of medicine box shell another
Annular convex platform, for the spout for the high-temperature fuel gas that injection SOLID PROPELLANT COMBUSTION generates.
The utility model has the advantages that the annular convex platform of medicine box shell left end of the invention increases the space residence time of ignition flame,
Enable solid propellant full combustion, ring of the high-temperature fuel gas for preventing SOLID PROPELLANT COMBUSTION from generating from medicine box shell right end
The quick pressure releasing when axially extending bore of shape boss sprays, shortens ignition delay time；Induction of the injection direction of ignition flame,
Increase the reliability of igniting；And then realize the fast starting of turbo blade.
Detailed description of the invention
Fig. 1 is structure composition figure of the invention.
Fig. 2 is the structure composition figure of medicine box enclosure interior of the invention.
Wherein, 1- ignition charge, 2- medicine box shell, 3- drug blocking, 4- diaphragm seal, 5- damping ring, 6- combustion chamber shell
Body, 7- solid propellant.
Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
A kind of gasifier section that can be quick started is present embodiments provided, referring to attached drawing 1 and Fig. 2, comprising: medicine box shell
Body 2, ignition charge 1, drug blocking 3, diaphragm seal 4, damping ring 5, burning chamber shell 6 and solid propellant 7；
Referring to attached drawing 2, the medicine box shell 2 is the circular casing with centre bore and the toroidal cavity coaxial with centre bore
Body, the both ends of the surface of toroidal shell each extend over out coaxial annular convex platform, and in the internal diameter and toroidal shell of annular convex platform
Diameter is identical；The both ends of the surface of toroidal shell are respectively equipped with the annular through-hole communicated with its internal toroidal cavity, enable toroidal cavity straight
The periphery of diameter maximum is great circle circumferential surface；Granular ignition charge 1 is installed, for drawing in the toroidal cavity of medicine box shell 2
Solid propellant 7 is fired, is set with damping ring 5 on the great circle circumferential surface of toroidal cavity, for slowing down punching caused by after ignition charge 1 is lighted
It hits；Drug blocking 3 is mounted in the toroidal cavity of medicine box shell 2, and the annular through-hole of 2 left end of medicine box shell is closed, for preventing
Stop gunpowder 1 drops out, and when ignition charge 1 burns, can burn simultaneously；Diaphragm seal 4 is mounted on the right side of medicine box shell 2, and
The annular through-hole of 2 right end of medicine box shell is closed, the ignition flame for generating after preventing ignition charge 1 from lighting leaks；
The burning chamber shell 6 is tubular construction closed at one end open at one end, the left end of open end and medicine box shell 2
