Description
Technical field
The utility model relates to a kind of link for solid propellant rocket, is specifically related to a kind of solid propellant rocket adapter coupling.
Background technique
The adapter coupling that the utility model relates to uses first on solid propellant rocket, the upper connection of Solid Rocket Motor combustion chamber housing mostly is link, with composite shell body by integral forming, adapter coupling is the expansion of joint, be connected with top cover and joint by link, as intermediate transit part, when meeting the secondary powder charge of solid propellant rocket two-stage combustion room, technique is to the requirement of housing open front, require the function with two pulse ignition devices simultaneously, and by adapter coupling and firing chamber internal portioning layer, combustion chamber is divided into two separate space, realize motor double pulsing working procedure.Therefore new structure is needed to meet solid propellant rocket above-mentioned functions.
Model utility content
The purpose of this utility model is to provide a kind of adapter coupling of solid propellant rocket, and it can solve the charge process problem of two-stage combustion room, bears housing inner pressuring load, can realize the function of solid propellant rocket two pulse igniting medicine box simultaneously.
The purpose of this utility model is achieved in that
This adapter coupling inside is the loop configuration of cavity; Described adapter coupling is provided with seal groove, and its end surface symmetric distributes two snap rings circumference locating slots; Its end face is uniformly distributed one week tapped hole, for installing top cover fixing bolt; Its end surface symmetric distributes two boss, and boss central position is provided with tapped hole, has small through hole at the bottom of tapped hole, and communicate with the inner annular cavity of this adapter coupling, the tapped hole on boss is for connecting electric igniter; The inner annular cavity opposite side of this adapter coupling is uniformly distributed through hole, is the ignition hole of ignition powder; The inner annular cavity of this adapter coupling is for installing ignition mechanism; This adapter coupling connects burning chamber shell and top cover, and this adapter coupling is connected by snap ring with shell joint, and this adapter coupling is connected by flange bolt with top cover, is threaded with igniter.
Be characterized in also comprising:
In above-mentioned adapter coupling structure, load seal ring in wherein said seal groove and coordinate with shell joint inner cylinder, realize sealed combustion chamber.
The metallic material of above-mentioned adapter coupling material selection high strength, lightweight.
This adapter coupling structure machine add-on type.
The utility model solid propellant rocket adapter coupling structure have employed above-mentioned technological scheme, makes it the function realizing switching top cover, hold inner pressuring load, ignition mechanism.There is advantage and good effect: set top cover and igniter cartridge, alleviate architecture quality, also save structure space.
