Abstract: A guided projectile including a precision guidance munition assembly utilizes angular rate sensors to sample a first angular velocity of the precision guidance munition assembly from the first angular rate sensor at a first time, sample a second angular velocity of the precision guidance munition assembly from the second angular rate sensor at the first time, generate a coning command based, at least in part, on the first angular velocity and the second angular velocity, and apply the coning command to the canard assembly. The range may be decreased or increased based on the coning commands.

Abstract: A projectile (10) for firing from a barrel (12) of a firearm has an elongated tubular body (14) with a leading end (16), a trailing end (18) and a passage (100) extending through the body (14) and opening onto the leading end (16). An insert (102) is disposed in the passage (100). A cavity (20) is formed in the body (14) between the insert (102) and the trailing end (18) for holding a volume of propellant. A seal arrangement (22) is formed on the body (14) and located between and in- board of the leading end (16) and the trailing end (18). The seal arrangement (22) extends circumferentially about body to form a substantial seal against an inner circumferential surface of the barrel (12). A driving band (28) is supported on the body (14) between the seal arrangement (22) and the trailing end (18) and arranged to maintain substantial coaxial alignment of the body (14) of the projectile and the barrel (12) of the firearm while the projectile travels along the barrel (12). The driving band (28) has one or more flow paths (38) that enable fluid communication between opposite axial ends of the driving band (28).

Abstract: 본 발명은 비중이 낮은 금속재로 탄두 전장(L)의 1/2이상의 길이 및 용적을 탄미에 내장함으로써, 탄두 무게중심(cg)이 탄두 헤드부에 있어 탄두의 편주각이 줄고, 이에 따라 비행간 탄두의 세차운동이 줄어들어 비행안정이 탁월하다. 종래의 탄두는 탄두 탄미부(C-100)에 무게중심이 있어서 일정거리 비행은 회전력에 의한 비행안정을 도모하나, 비행속도가 줄어드는 일정거리부터는 점차적으로 탄미부가 전도되게 되어 전면의 저항력이 더욱 증가되고, 이로 인해 사거리가 줄어들고 더욱 더 정확도는 낮아진다. 상기와 같은 문제점을 개선하기 위해서 탄두의 중간체를 비중이 낮은 금속재로 일정용적을 채움으로써 헤드부로 무게중심을 이동시켜 편주각을 줄이고, 세차 회전운동을 현저히 작게하여 비행진행간 전면 저항력을 줄이며 목표물에 최종 접촉되는 최소의 면적으로 파괴력을 증대시키며 비행간 전도되지 않아 정확도 및 파괴력과 사거리가 연장된다. 본 발명의 탄두는 사거리 연장을 비롯한 정확도 향상과 파괴력 증대 및 저지력이 우수한 탄두이며, 탄심체와 중간체, 자켓부로 분리하여 압입, 단조, 드로잉하여 조립하는 것만으로도 탄두를 제조할 수 있기 때문에 제작성이 향상되는 동시에 탄두의 성능은 더욱 증대된다.

Abstract: A penetrator (100) includes a fore body (120) having a center of aerodynamic pressure (122) forward of a center of gravity (120) and a stabilizing portion (104) removably attached to the fore body such that, when attached to the fore body, a center of gravity for the penetrator is forward of a center of aerodynamic pressure for the penetrator. A method of using a penetrator includes propelling the penetrator toward a first target, penetrating the first target with a fore body of the penetrator, and detaching a stabilizing portion of the penetrator from the fore body. The method further includes impacting the second target with the fore body.

Abstract: A control surface restraining system for variably preventing movement of a control surface imparted by a control actuation shaft of a control actuation section of a tactical flight vehicle includes a power take-off shaft operably connected to the control actuation shaft with a power take-off gear train and a control surface restraint. The control surface restraint is configured to variably engage the power take-off shaft, thereby locking the power take-off gear train and preventing the control actuation shaft from imparting the movement of the control surface. The control surface restraint is also configured to variably disengage the power take-off shaft, thereby unlocking power take-off gear train and allowing the control actuation shaft from imparting the movement of the control surface.

Abstract: Techniques are disclosed for providing retractable control fins on an underwater vehicle. The retractable control fins can be extended away from a main hull portion of the underwater vehicle and retracted inwards to a stowage region within the hull portion to protect the fins from damage and reduce an overall outer diameter (e.g., in the case of a cylindrical body) of the underwater vehicle. In some embodiments, the control fins are folded inwards to reduce the vehicle diameter. In other embodiments, the control fins are pulled inwards using a rotating structure designed to slide the control fins through an opening and into an inner portion of the hull to reduce the vehicle diameter. The retraction of the fins through the various retraction mechanisms reduces the envelope diameter of the underwater vehicle.
