Description
Technical Field
The invention belongs to the technical field of missile launching devices, and particularly relates to a composite material concentric cylinder structure.
Background
The CCL employs two concentric cylinders to launch the DD and provides initial flight guidance of the DD and a gas discharge path. The gas is discharged from an outlet on the FS cylinder base plate after being ejected from the rocket engine, and flows 180 degrees under the action of a hemispherical end cover to enter an annular space and is discharged to the atmosphere. The concentric cylinders are known for simple structure, and comprise an inner cylinder for restraining the missile, an outer cylinder for restraining the exhaust flame, a hemispherical end cover for realizing gas steering, an adjustable thrust booster and a longitudinal beam between the inner cylinder and the outer cylinder. Wherein the inner cylinder plays a role in supporting and guiding the missile. The longitudinal beam plays a supporting role for the inner cylinder and is also a connecting component between the outer cylinder and the inner cylinder. The space enclosed by the inner cylinder, the outer cylinder and the longitudinal beam forms a gas exhaust and guide channel during the thermal launch of the rocket. When the DD engine works, high-speed high-temperature fuel gas flows through the thrust booster, turns to reverse flow at 180 degrees at the guide end cover, flows upwards to a fuel gas discharge and guide channel between the inner cylinder and the outer cylinder, and is discharged from the upper end of the concentric FS cylinder.

In addition, the device has the characteristics of simple structure, light weight and low manufacturing cost. Each FS cylinder is self-made into a system and can independently complete the whole processes of storage, transportation, filling and FS of DD.
Because the concentric FS cylinder is required by heat resistance, cylinder strength, corrosion resistance, air tightness and the like, the whole cylinder is welded by stainless steel or other high-strength corrosion-resistant alloys at present, and the longitudinal beam, the longitudinal bar and the inner cylinder and the outer cylinder are connected by adopting a metal welding technology so as to ensure the connection strength and support the inner cylinder and the outer cylinder.
