Barrel missile
The "Avant-garde I" missile is installed in the launcher to form a barrel-mounted missile. The launcher can be used not only as a packaging tube for carrying, transporting and keeping missiles, but also as a support for aiming at targets and launching missiles in combat. The launch tube is completely sealed and equipped with moisture-proof device. The "Avant-garde-1" missile is a blunt slender cylinder with a semi-spherical head, a cylindrical body and a "stern" tail. It has a pair of movable rudder surfaces installed in the rudder cabin at the front of the missile body, and two pairs of trapezoidal tails are installed on the tailstock at the periphery of the main engine nozzle, forming an "X-X"-shaped canard pneumatic layout. When the missile is in the launcher, the rudder surface is folded in the rudder cabin and the tail is folded circumferentially. When the missile is out of the barrel, the rudder surface and tail wing are automatically deployed by elasticity. The missile consists of four cabins, from front to back: seeker cabin, rudder cabin, warhead cabin and combined power unit.
The seeker cabin includes two parts: coordinator and electronic cabin. The coordinator is a gyro tracking device with infrared optical system and a detector. The electronic cabin mainly includes seeker tracking circuit and missile autopilot circuit. Avant-garde 1 seeker adopts cooled indium antimonide detector, which has strong tracking ability and long detection distance, and can detect infrared radiation of the target in all directions and suppress background interference. Its coordinate machine adopts conical scanning system, which has no detection blind area and large capture field of view. The circuits on the seeker are all integrated and adopt micro-assembly technology, which has high reliability, small structural size and light weight. The missile is equipped with a target adaptive guidance system, which can automatically identify the target type, so as to fly directly to the target entity at the end of the flight and obtain the best killing effect.
Steering engine room
The cabin is equipped with steering gear components to control the flight of missiles, as well as airborne batteries and airborne cooling air bottles to provide power and cooling gas for missiles in flight. An angular velocity sensor/demodulator is also installed here to measure the angular velocity of the projectile swinging around its horizontal axis.
Warhead cabin, including warhead and fuze. The warhead is cylindrical and adopts semi-prefabricated fragments, which belongs to fragment killing blasting type. The fuse was triggered. If the missile fails to hit the target within the specified time, the self-destruction device of the fuze can make the missile explode and self-destruct. The combined power plant consists of launch engine, main engine and tail assembly. The launch engine is used to launch the missile out of the barrel, giving the missile the necessary speed and rotation speed. The launch engine was completely burned before leaving the launch barrel, and separated from the main engine in the barrel.
The main engine is a double thrust solid rocket engine. Its primary thrust can make the missile reach the cruising speed in a very short time, and the secondary thrust is used to maintain these two speeds during the cruising phase. The main engine adopts electronic delay ignition, which ignites after the missile flies away from the shooter's safe distance to avoid the tail flame of the main engine burning the shooter.
The empennage assembly consists of four trapezoidal wings and empennage seats. The tail wing can provide the lift of the missile, and the well ensures the flight stability of the missile. The tail of "Avant-garde I" is installed obliquely (the plane where the tail is located has a certain angle with the axis of the missile), thus generating a rolling moment in flight, so that the missile can obtain the necessary rolling speed.
Launching mechanism
The launching mechanism is mainly used for missile launch preparation and launch control. The launching mechanism is equipped with a starting handle. As soon as the handle is twisted, the ground battery/refrigeration bottle combination will be activated to supply power and gas to the equipment on the missile, and the missile can start immediately. When the seeker intercepts the target, the launching mechanism automatically analyzes the information signal from the seeker and informs the shooter of the analysis result in the form of acousto-optic signal. If the launching conditions are met, the shooter pulls the trigger, the battery on the missile and the launching engine are activated and ignited in turn, and the missile is launched from the barrel. The launching mechanism of "Avant-garde One"-Speedman, controls the launching conditions extremely strictly.
Ground battery/refrigerator bottle combination
The ground battery is a disposable chemical thermal battery, surrounded by a refrigeration bottle and stored with high-pressure helium to ensure the temperature required for the normal operation of the indium antimonide detector. The combination is easy to carry and store without maintenance. When fighting, it can be used by inserting it into the interface on the launcher.
