Description
Technical field
It is hardened more particularly, to a kind of polyurethane and rubber and plastic the present invention relates to a kind of guided missile adapter co-curing moulding process
The guided missile adapter co-curing reaction of conjunction.
Background technology
Guided missile adapter is the important component in the cold ejection system of guided missile, is between guided missile and launch canister (case)
Connection and support meanss.Adapter is arranged between guided missile and firing box in annular gap, storage, fortune to guided missile
Defeated, handling and transmitting have extremely important effect, and the designing technique of adapter is one of key technology of canister launch system.
The lateral vibration damping of canister launch guided missile supports system to experienced from hydraulic system between the inner/outer tube of early stage to pad system inner/outer tube
The development of liner system (i.e. adapter) between system, then cylinder finally.Such as U.S.'s submarine-launched missile aimed at objectives on land, " (nineteen sixty takes Polaris A1 "
Labour), " Polaris A2 " (1962 be on active service) emission system uses liquid-springing mode between inner/outer tube, " Polaris A3 " (1964
Year is on active service) foamed plastics progress vibration damping between inner/outer tube is used, " sea God C3 " (being on active service for 1971), " trident IC4 " (clothes in 1979
Labour), " trident IID5 " (1989 be on active service) etc. emission system then uses liner system between cylinder.First two system is to transmitting
For the horizontal space utilization rate of case than relatively low, structure is more complicated, manufactures installation difficulty, and adapter is then effectively between using cylinder
The size of laterally supporting system is reduced, improves the horizontal space utilization rate of firing box, manufacture and installation are also more convenient.Make
For guided missile and the adapter of firing box contact interface, its effect is mainly：Supporting role is provided to guided missile；Rushed in firing box
When hitting or vibrating damping effect is provided to guided missile；Guide effect in transmitting to guided missile；To guided missile combustion gas stream in firing box
Flat pads different possible sealing function is different to the emphasis of adapter performance requirement, and this is that adapter is carried out
