Abstract
The utility model provides a shock-resisting solid ramjet engine shell body connecting lug structure. The shock-resisting solid ramjet engine shell body connecting lug structure comprises a shell body. Four external connecting lugs are distributed at the back end of the shell body in an equal central angle mode. Each external connecting lug comprises a lug body which is provided with an explosive bolt installation hole, wherein the two sides of the lug body are provided with reinforcing ribs, a vibration absorption groove is formed in the root of the external connecting lug and at the combination position between the lug body and the reinforcing ribs, and the reinforcing ribs are provided with lightening holes. The thickness of the lug body of each external lug is 6mm, the thickness of the reinforcing ribs on the two sides is 5mm, the width of each vibration absorption groove is 5mm, the depth of each vibration absorption groove is 10mm, and the groove bottom is an arc with the diameter of 5mm. Positioning holes are formed around the explosive bolt installation holes, and the stress vibration absorption grooves are formed in the roots of the lugs to buffer the impulsive load. The connecting strength of the connecting lugs is high. The connecting lugs can bear large impulsive load, absorb impact energy, reduce the stress and strain of the thin-wall shell body, protect a heat insulating layer inside the thin-wall engine shell body, and can prevent damage caused by too large deformation. The shock-resisting solid ramjet engine shell body connecting lug structure is ingenious in design, the structure is simplified, and the passive weight is reduced.
Description
Technical field
The utility model belongs to Ducted rocket structure field, is specifically related to a kind of shock resistance Ducted rocket housing and connects support lug structure.
Background technique
When starting, Ducted rocket needs certain initial velocity, in order to guarantee that Ducted rocket can normally turn level work, usually connect a booster at the Ducted rocket afterbody, at first Ducted rocket is accelerated to and turn the Mach number that level needs, Ducted rocket turns level work again.Booster work is complete, from body, separates.Separate mode adopts blasting bolt, can produce great impact, and abutted flange need to have enough intensity, and weight also requires gently, and structure also will meet the requirement of body aerodynamic configuration simultaneously.Connect journal stirrup ineffective after stage separation, but the Ducted rocket housing also needs to maintain enough strength and stiffness, meet follow-up usage requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of shock resistance Ducted rocket housing to connect support lug structure, and is simple in structure, connects reliably, effectively alleviates the passive weight of motor combustion chamber case.
The technical solution of the utility model: shock resistance Ducted rocket housing of the present utility model connects support lug structure and comprises housing, at the central angles such as the housing rear end chord ear outside four that distributes, outer chord ear comprises the ear body, the blasting bolt mounting hole is arranged on the ear body, the stiffening rib of ear body both sides, there is the absorbing groove root of chord ear, ear body and stiffening rib junction outside, design lightening hole on stiffening rib.
The ear body thickness of slab 6mm of described outer chord ear, the stiffening rib thickness of slab 5mm of both sides; Described absorbing groove width 5mm, dark 10mm, bottom land is diameter 5mm circular arc.
The blasting bolt that is locked is arranged around described blasting bolt mounting hole a circle screw.
Advantage of the present utility model: connection journal stirrup join strength of the present utility model is high; can bear larger impulsive load, also can apparatus with shock absorbing, reduce stress and the distortion of thin-wall case as far as possible; and the heat insulation layer of protection thin-walled motor body, prevent because being out of shape excessive the damage.The utility model design is ingenious, simplifies the structure, and effective alleviates passive weight.

Fig. 2 is the support lug structure schematic diagram.
Fig. 3 is that the A of Fig. 2 is to structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 3 as shown in Figure 1, Figure 2: shock resistance Ducted rocket housing of the present utility model connects support lug structure and comprises housing 1, it is characterized in that: at the central angles such as the housing 1 rear end chord ear 1d outside four that distributes, outer chord ear 1d comprises ear body 1d1, blasting bolt mounting hole 1d5 is arranged on ear body 1d1, the stiffening rib 1d2 of ear body 1d1 both sides, there is absorbing groove 1d3 the root of chord ear 1d, ear body 1d1 and stiffening rib 1d2 junction outside, the upper design of stiffening rib 1d2 lightening hole 1d4.
The ear body 1d1 thickness of slab 6mm of described outer chord ear 1d, the stiffening rib 1d2 thickness of slab 5mm of both sides; The wide 5mm of described absorbing groove 1d3, dark 10mm, bottom land is diameter 5mm circular arc.
The circle screw (1d 6) that the blasting bolt that is locked is arranged around described blasting bolt mounting hole 1d5.
Its middle ear body 1d1 docks with the cabin section, is designed with positioning hole 1d 6 and blasting bolt mounting hole 1d5 on ear body 1d1.Circumferential location when positioning hole 1d 6 is used for achieving a butt joint, blasting bolt mounting hole 1d 5 is used for installing blasting bolt, realizes location circumferentially being installed and realizing stage separation.
The journal stirrup side is designed with two stiffening rib 1d2, improves the join strength of journal stirrup.Under the prerequisite that guarantees join strength, be designed with lightening hole 1d4 on stiffening rib 1d2, alleviate passive weight.Because inevitably can producing stress, concentrates the journal stirrup root, in order to reduce stress, and shock absorbing load, connection journal stirrup root is designed with and falls stress absorbing groove 1d3.Fall stress absorbing groove structure and be U-shaped, can effectively alleviate the impact of impacting thin-wall case, apparatus with shock absorbing; the heat insulation layer of protection thin-walled motor body; also have simultaneously enough intensity and rigidity, and reduce stress and the distortion of thin-wall case as far as possible, the impact that the buffering blasting bolt produces.
