Description

Technical Field

[0001] The utility model relates to a separation cabin for a patrol vehicle and a carrier. Background Art

[0002] Stage separation is a link that multi-stage aircraft must go through during flight. In order to ensure that the aircraft can smoothly perform subsequent flight missions, it is necessary to ensure that the patrol vehicle can safely and reliably unlock and separate from the carrier that has completed the transportation work, so as to reduce the quality of the aircraft's subsequent missions, ensure the flight altitude and range of the patrol vehicle, and at the same time reduce the impact caused by differences in aerodynamic shapes, and avoid excessive ballistic disturbances and control divergence during the subsequent flight of the patrol vehicle.

[0003] The cruiser is a plane-symmetrical aircraft, and the carrier is an axisymmetric aircraft. First, during the ground assembly process, the two-stage aircraft need to be connected, and the cruiser needs to fold its wings and rudder surfaces before separation, and needs to be wrapped with a fairing to ensure the overall aerodynamic shape of the aircraft.

[0004] When the patrol vehicle and the carrier stage are separated, the patrol vehicle is a large cantilever connection structure, and is in a complex airflow disturbance and coupled vibration environment of the structure and airflow. The separation mechanism is subject to large loads and complex working conditions. The separation of the patrol vehicle and the carrier has a large overload impact, and because the patrol vehicle is in an uncontrolled state during separation, the separation posture is easily affected by the separation mechanism.

[0005] In addition, the separation of the fairing has high synchronization requirements. Asynchronous separation will cause the attitude instability of the projectile, collision and interference between the cruiser and the carrier, and lead to separation failure. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0027] A separation cabin for a patrol vehicle and a carrier, wherein a first set of separation mechanisms connects and unlocks a fairing and a connection cabin through an explosive bolt separation mechanism, and a separation hinge limits the separation direction of the fairing to complete the separation of the fairing. A second set of separation mechanisms completes the unlocking and separation of the patrol vehicle and the carrier through an energy-gathering cutting cable assembly. After the separation of the fairing is completed, the cutting cable explodes in a direction corresponding to the separation area of ​​the pressure ring, so that the patrol vehicle and the carrier are unlocked and separated.

[0028] include:

[0029] The shell 1 is evenly equipped with a plurality of explosive bolts 6, the threaded ends of the explosive bolts 6 extend out of the front end surface of the shell 1 and are connected to the fairing. When separation is required, the bolts are detonated by the detonator to unlock and separate the fairing. The front end surfaces on opposite sides of the shell 1 are processed with installation notches, and a separation hinge 2 is respectively installed in the installation notches;

[0030] A connecting ring 4, a pressing ring 9 is installed in the front end of the connecting ring 4, and a cutting rope 3 is installed between the connecting ring 4 and the pressing ring 9;

[0031] The connecting ring 4 is installed at the center of the housing 1 through a plurality of connecting ribs 10 , and a detonating device 5 is installed on the connecting ribs 10 to detonate the explosive bolts 6 .

[0032] The housing 1 is annular, and an annular groove is processed on its inner ring. The explosive end of the explosive bolt 6 is placed in the annular groove, and the threaded end extends out from the through hole on the front end surface of the housing 1.

[0033] The fairing is connected and unlocked and separated from the connection cabin through the explosive bolt separation mechanism. The separation hinge is installed on the cabin body. The separation hinge is provided with a rotating shaft and a sliding groove. After the explosive bolt is detonated, the fairing can only rotate along the sliding groove. After the fairing rotates to a certain angle, the fairing is unhooked from the separation hinge and moves outward to complete the separation from the carrier to avoid collision. After the fairing is separated, the patrol vehicle is unlocked and separated from the carrier through the cutting rope separation mechanism.

[0034] The connecting ring 4 and the pressure ring 9 are both hollow cylinders, and an annular groove is processed on the outer wall of the pressure ring 9, and the cutting rope 3 is installed in the annular groove. The connecting ring and the separation cabin are connected by radial screws, and a detonating cord is placed on the connecting ring and the missile connecting cabin. When the separation signal is received, the detonating cord is ignited and detonated, cutting the cabin into two parts, unlocking the UAV and the carrier missile, and after the fairing is opened, the aerodynamic resistance difference between the patrol vehicle and the carrier is used to achieve separation.

[0035] A plurality of flame extinguishing holes 12 are processed on the side walls of the pressure ring 9 and the connecting ring 4. The flame extinguishing holes 12 release the heat of the cutting rope 3 during the combustion process to prevent the heat from directly impacting the patrol aircraft.

[0036] The separation hinge 2 is square, and a hinge cavity 14 is processed in the middle of one side of the separation hinge 2. Ear pieces 13 are respectively installed at the edges of the opening of the hinge cavity 14 at both ends of the separation hinge 2, and the ear pieces 13 are fixed to the bottom of the annular groove.

[0037] The hinge cavity 14 is set to be open at one end relative to the installation notch, and the hinge seat at the end of the fairing extends into the hinge cavity and is hinged to the rotating shaft 7. A sliding groove 8 is processed on the side wall between the rotating shaft 7 and the opening of the hinge cavity 14 as a limiting structure for the fairing to expand to both ends after the explosion of the explosive bolt. The sliding groove 8 is perpendicular to the bottom of the hinge cavity 14 and is processed with a flared mouth to prevent the fairing from being stuck.

[0038] The two ends of the connecting rib plate 10 are respectively connected to the rear end faces of the shell 1 and the connecting ring 4, and a vertical reinforcing rib 11 is provided between the connecting rib plate 10 and the connecting ring 4, and the vertical reinforcing rib 11 is parallel to the axial direction of the connecting ring 4. The connecting rib plate allows air permeability between the shell and the connecting ring, and the vertical reinforcing rib 11 ensures that the connecting ring 4 can withstand the impact force of the explosion process.
