Description

FIELD OF THE INVENTION [0001] The present invention relates to an ignition delay device and an ignition delay device having the ignition delay device,

본 발명은 점화 지연 장치 및 이를 구비한 사거리 연장탄에 관한 것으로 더 상세하게는 탄 발사 시 발생되는 셋백(setback) 힘을 이용하여 작동되어 탄의 회전속도 및 탄저부 압력 변화에 의한 지연시간 변화가 발생되지 않고 안정적인 작동을 가능하게 한 점화 지연 장치 및 이를 구비한 사거리 연장탄에 관한 발명이다. More particularly, the present invention relates to an ignition delay device and an extended range gun having the ignition delay device. More particularly, the present invention relates to an ignition delay device, And an ignition delay device capable of stable operation without occurrence of the ignition delay, and an extended ignition gun having the ignition delay device.

일반적으로 저항력탄과 더불어 사거리 연장탄에 가장 먼저 적용된 기술은 로켓 보조 추진탄이다. Generally, the first technique applied to a range extension gun, along with a resistive shot, is a rocket assisted propulsion gun.

로켓 추진탄의 추진장치는 로켓 추진제, 추력노즐 및 지연 점화장치로 구성된다. The propulsion unit of the rocket propulsion consists of rocket propellant, thrust nozzle and delay ignition device.

최적의 로켓 작동 시점은 발사 조건에 따라 달라지지만 일반적으로 공기 항력이 줄어드는 수초 후이다. The optimal rocket operating time depends on the firing conditions, but is typically a few seconds after the air drag decreases.

이러한 점화지연시간은 점화지연장치를 이용하는데 화공식 지연장치가 간단하므로 많이 이용된다. This ignition delay time is widely used because it is simple to use an ignition delay device.

지연장치는 노즐내부에 장착되어 로켓 점화와 동시에 모타내의 압력으로 후방으로 분리된다. 추진장약에 의해 발사될 때 포강내에서 고압의 연소가스가 로켓 모타로 들어가는 경우 폭발의 위험이 있으므로 점화지연장치와 노즐결합체 사이에 확실한 밀봉이 되어야 한다. The retarder is mounted inside the nozzle and is separated backward by the pressure in the motor at the same time as the rocket ignition. When high pressure combustion gases enter the rocket motor in a pellet when launched by propellant charge, there is a risk of explosion and there must be a secure seal between the ignition retarder and the nozzle assembly.

즉, 지연점화장치는 장사정탄의 일종인 로켓 보조탄(Rocket-Assisted Projectile)의 로켓 추진기관을 일정 시간 지연 후 점화시키는 역할을 수행한다. 현재는 복합추진방식으로 개발된 사거리 연장탄에도 적용되고 있다.That is, the delayed ignition device ignites a rocket propulsion engine of a rocket-assisted projectile, which is a type of commercial artificially charger, after a certain time delay. Currently, it is also applied to the range extension gun developed by the combined propulsion method.

기존의 점화지연장치는 추진장약에 의해 포강내 고압의 연소가스에 의해 점화제가 점화된다. In the conventional ignition delay device, the ignition agent is ignited by the high-pressure combustion gas in the in-line by the propellant charge.

즉, 종래 점화지연장치는 고압의 연소 가스가 점화지연장치의 점화원이 되기 때문에 점화제를 비롯한 점화장치 내부의 화약은 작동과 동시에 외부에 노출되게 되어 탄의 회전과 발사 고각에 의해 지연시간이 변하는 문제점이 있었다. That is, in the conventional ignition delay device, since the high-pressure combustion gas becomes the ignition source of the ignition delay device, the gunpowder in the ignition device including the ignition agent is exposed to the outside at the same time as the operation and the delay time is changed There was a problem.

[

타격식 뇌관 지지부(500)는 링형상으로 형성되는 링몸체(510)와 링몸체(510)에서 돌출되어 타격식 뇌관부(400)를 지지하는 뇌관 지지체(520)를 구비한 안전링부재인 것을 일 예로 한다.
