To realize above-mentioned technical purpose, the technical proposal of the invention is realized in this way：
A kind of anti-torsion row's hungry ghosts who spit fire's structure of vehicle thermal release interstage section, including covering, the covering lower edge are provided with lower end
Frame, the covering middle inside is provided with middle boxes, and some row hungry ghosts who spit fire, the row are provided between the lower end frame and the middle boxes
Hungry ghosts who spit fire includes the rectangle row hungry ghosts who spit fire and triangle row hungry ghosts who spit fire of spaced setting, and the triangle row hungry ghosts who spit fire includes about two phases
Arrange the identical right angled triangle of setting hungry ghosts who spit fire, the hypotenuse of the two right angled triangles row hungry ghosts who spit fire being oppositely arranged up and down it
Between covering formation shearing resistance oblique pull band.
Further, load stringer is provided between the adjacent row hungry ghosts who spit fire.
Further, in the adjacent two triangle row hungry ghosts who spit fire, one of triangle arranges the shearing resistance oblique pull of hungry ghosts who spit fire
Band is Right deviation shearing resistance oblique pull band, and the shearing resistance oblique pull band of another triangle row hungry ghosts who spit fire is left-leaning shearing resistance oblique pull band.
Further, the number of the rectangle row hungry ghosts who spit fire is 20, and the number of the triangle row hungry ghosts who spit fire is 20.
Beneficial effects of the present invention：Subtract oblique pull band by setting to resist, both ensure that existing vehicle interstage section row hungry ghosts who spit fire's
Flame area is arranged, the shear resistance that rectangle arranges hungry ghosts who spit fire greatly improved again, improve the torsional rigidity of interstage section, solve especially
This conspicuous contradiction that middle-size and small-size vehicle interstage section row's flame area and torsional rigidity must be taken into account.While the structure type of the present invention
Simple novel, principle is reliable, it is not necessary to change original technique assembling link, technique realizability is good, and increased weight generation
Valency very little, solves the problem of existing interstage section row hungry ghosts who spit fire anti-torsion ability is not enough well.
