Guided Missile
In military terminology, a missile is a guided airborne ranged weapon capable of self-propelled flight usually by a jet engine or rocket motor. Missiles are thus also called guided missiles or guided rockets (when a previously unguided rocket is made guided). Missiles have five system components: targeting, guidance system, flight system, engine and warhead. Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles (ballistic, cruise, anti-ship, anti-submarine, anti-tank, etc.), surface-to-air missiles (and anti-ballistic), air-to-air missiles, and anti-satellite weapons. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Unguided jet- or rocket-propelled weapons are usually described as rocket artillery. Historically, the word ''missile'' referred to any projectile that is thrown, shot or propelled towards a target; this usage is ...

Rocket
A rocket (from it, rocchetto, , bobbin/spool) is a vehicle that uses jet propulsion to accelerate without using the surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Signific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydra 70
The Hydra 70 rocket is a diameter fin-stabilized unguided rocket used primarily in the air-to-ground role. It can be equipped with a variety of warheads, and in more recent versions, guidance systems for point attacks. The Hydra is widely used by US and allied forces, competing with the Canadian CRV-7, with which it is physically interchangeable. Overview The Hydra 70 is derived from the diameter Mk 4/Mk 40 Folding-Fin Aerial Rocket developed by the United States Navy for use as a free-flight aerial rocket in the late 1940s. The Mk 40 was used during the Korean and Vietnam wars to provide close air support to ground forces from about 20 different firing platforms, both fixed-wing and armed helicopters. The main change made to produce the Hydra was the Mk. 66 motor which uses a new propellant that offers considerably more thrust, (Mod 2/3) (Mod 4). The fins of the Mk 40 flipped forward from the rear when the rocket left the launching tube, but in the Hydra they are curved ...

Proximity Fuse
A proximity fuze (or fuse) is a Fuze (munitions), fuze that detonates an Explosive material, explosive device automatically when the distance to the target becomes smaller than a predetermined value. Proximity fuzes are designed for targets such as planes, missiles, ships at sea, and ground forces. They provide a more sophisticated trigger mechanism than the common contact fuze or timed fuze. It is estimated that it increases the lethality by 5 to 10 times, compared to these other fuzes. Background Before the invention of the proximity fuze, detonation was induced by direct contact, a timer set at launch or an altimeter. All of these earlier methods have disadvantages. The probability of a direct hit on a small moving target is low; a shell that just misses the target will not explode. A time- or height-triggered fuze requires good prediction by the gunner and accurate timing by the fuze. If either is wrong, then even accurately aimed shells may explode harmlessly before reaching ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-active Laser Homing
Laser guidance directs a robotics system to a target position by means of a laser beam. The laser guidance of a robot is accomplished by projecting a laser light, image processing and communication to improve the accuracy of guidance. The key idea is to show goal positions to the robot by laser light projection instead of communicating them numerically. This intuitive interface simplifies directing the robot while the visual feedback improves the positioning accuracy and allows for implicit localization. The guidance system may serve also as a mediator for cooperative multiple robots. Examples of proof-of-concept experiments of directing a robot by a laser pointer are shown on video. Laser guidance spans areas of robotics, computer vision, user interface, video games, communication and smart home technologies. Commercial systems Samsung Electronics Co., Ltd. may have been using this technology in robotic vacuum cleaners since 2014. Google Inc. applied for a pa ...

Advanced Precision Kill Weapon System
The AGR-20 Advanced Precision Kill Weapon System (APKWS) is a design conversion of Hydra 70 unguided rockets with a laser guidance kit to turn them into precision-guided munitions (PGMs). APKWS is approximately one-third the cost and one-third the weight of the current inventory of laser-guided weapons, has a lower yield more suitable for avoiding collateral damage, and takes one quarter of the time for ordnance personnel to load and unload. Development Where possible the system utilizes existing Hydra 70 components such as launchers, rocket motors, warheads and fuzes. The weapon bridges the gap between the Hydra 70 and AGM-114 Hellfire systems and provides a cost-effective method of engaging lightly armored point targets. APKWS is the U.S. government's only Program of Record for the semi-active, laser-guided 2.75-inch (70 millimeter) rocket. It converts the Hydra 70 unguided rocket into a precision guided munition through the addition of a mid-body guidance unit develop ...

Low-Cost Guided Imaging Rocket
The Low-Cost Guided Imaging Rocket was a weapons system under development for the US Navy as part of ONR's Low-Cost Imaging Terminal Seeker (LCITS) FNC. It transitioned as the weapon used in the Medusa Joint Capability Technology Demonstration with South Korea. The program provided a precision guided 2.75 inch (70 mm) rocket for use with existing Hydra 70 systems in service, as such it has many similarities with the Advanced Precision Kill Weapon System program. The principal difference between the systems is that while APKWS uses terminal laser homing, requiring the target to be 'painted' until impact, LOGIR would guide to a position supplied by the launching aircraft, using imaging infrared in the terminal phase making it a true fire-and-forget weapon. Another advantage of LOGIR was that it was "especially effective against swarm attacks by enemies like small boats, as there’s no need for ongoing guidance." The South Korean version, designated K-LOGIR, is used on the R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
