Missile Lofting
Lofting is a trajectory optimization technique used in some missile systems to extend range and improve target engagement effectiveness, usually in beyond-visual range scenarios. Method Lofting involves a missile ascending to a higher altitude after launch, creating a parabolic arc similar to Ballistic Missiles, before descending toward its target. This elevated flight path allows the missile to capitalize on reduced air resistance at higher altitudes, increasing both the missile's potential energy and the kinetic energy during terminal guidance, thus enabling greater range and Probability of kill.

Trajectory Optimization
Trajectory optimization is the process of designing a trajectory that minimizes (or maximizes) some measure of performance while satisfying a set of constraints. Generally speaking, trajectory optimization is a technique for computing an open-loop solution to an optimal control problem. It is often used for systems where computing the full closed-loop solution is not required, impractical or impossible. If a trajectory optimization problem can be solved at a rate given by the inverse of the Lipschitz constant, then it can be used iteratively to generate a closed-loop solution in the sense of Caratheodory. If only the first step of the trajectory is executed for an infinite-horizon problem, then this is known as Model Predictive Control (MPC). Although the idea of trajectory optimization has been around for hundreds of years (calculus of variations, brachystochrone problem), it only became practical for real-world problems with the advent of the computer.

AIM-120 AMRAAM
The AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM) ( ) is an American Beyond-visual-range missile, beyond-visual-range air-to-air missile capable of all-weather day-and-night operations. It uses active transmit-receive radar guidance instead of semi-active receive-only radar guidance. When an AMRAAM missile is launched, NATO pilots use the Multiservice tactical brevity code, brevity code "Fox (code word), Fox Three". The AMRAAM largely replaced the AIM-7 Sparrow as the principal beyond-visual-range air-to-air missile in U.S. inventory. more than 14,000 had been produced for the United States Air Force, the United States Navy, and 33 international customers. The AMRAAM has been used in several engagements, achieving 16 air-to-air kills in conflicts over Iraqi no-fly zones conflict, Iraq, Operation Deny Flight, Bosnia, Operation Allied Force, Kosovo, 2019 Jammu and Kashmir airstrikes, India, and Syrian Civil War, Syria. In the long term, it is expected to eventually be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Missile Technology
A missile is an airborne ranged weapon capable of self-propelled flight aided usually by a propellant, jet engine or rocket motor. Historically, 'missile' referred to any projectile that is thrown, shot or propelled towards a target; this usage is still recognized today with any unguided jet- or rocket-propelled weapons generally described as rocket artillery. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Missiles are also generally guided towards specific targets termed as guided missiles or guided rockets. Missile systems usually have five system components: targeting, guidance system, flight system, engine, and warhead. Missiles are primarily classified into different types based on firing source and target such as surface-to-surface, air-to-surface, surface-to-air and air-to-air missiles. Terminology Missile is derived from Latin "missilis" meaning "that may be thrown". T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Missile Guidance
Missile guidance refers to a variety of methods of guiding a missile or a guided bomb to its intended target. The missile's target accuracy is a critical factor for its effectiveness. Guidance systems improve missile accuracy by improving its Probability of Guidance (Pg). These guidance technologies can generally be divided up into a number of categories, with the broadest categories being "active", "passive", and "preset" guidance. Missiles and guided bombs generally use similar types of guidance system, the difference between the two being that missiles are powered by an onboard engine, whereas guided bombs rely on the speed and height of the launch aircraft for propulsion. History The concept of unmanned guidance originated at least as early as World War I, with the idea of remotely guiding an airplane bomb onto a target, such as the systems developed for the R.F.C. World War I Drone Weapons, first powered drones by Archibald Low (the father of radio guidance). In World War ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-to-air Missile
An air-to-air missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft (including unmanned aircraft such as cruise missiles). AAMs are typically powered by one or more rocket motors, usually solid-fuel rocket, solid fueled but sometimes liquid-fuel rocket, liquid fueled. Ramjet engines, as used on the Meteor (missile), Meteor, are emerging as propulsion that will enable future medium- to long-range missiles to maintain higher average speed across their engagement envelope. Air-to-air missiles are broadly put in two groups. Those designed to engage opposing aircraft at ranges of around 30 km to 40 km maximum are known as short-range or "within visual range" missiles (SRAAMs or WVRAAMs) and are sometimes called "dogfight" missiles because they are designed to optimize their agility rather than range. Most use infrared guidance and are called heat-seeking missiles. In contrast, medium- or long-range missiles (MRAAMs or LRAAMs), which ...

Sea Skimming
Sea skimming is a technique many anti-ship missiles and some fighter or strike aircraft use to avoid radar and infrared detector, infrared detection and to lower the probability of being shot down during their approach to the target. Method Sea-skimming anti-ship missiles try to fly as low as is practically achievable, which is almost always below 50 meters (150 Foot (length), ft), and is often near 2 meters (6 ft). When under attack, a warship can detect sea-skimming missiles only after they appear over the horizon (about 28 to 46 km from the ship), allowing about 25 to 60 seconds of warning. Advantages By flying low to the sea, missiles decrease the range at which the target ships can detect them by a significant amount. Flying at a lower altitude increases the amount of time the missile is under the horizon from the perspective of the target ship, making it harder to detect due to Radar#Clutter, radar clutter from the sea and similar effects.

R-77
The Vympel NPO R-77 missile (NATO reporting name: AA-12 Adder) is a Russian active radar homing beyond-visual-range air-to-air missile. It is also known by its export designation RVV-AE. It is the Russian counterpart to the American AIM-120 AMRAAM missile. The R-77 was marked by a severely protracted development. Work began in the 1980s, but was not completed before the Soviet Union fell. For many years, only the RVV-AE model was produced for export customers. Production was further disrupted when the Russo-Ukrainian War resulted in a Ukrainian arms embargo against Russia, severing supply chains. The Russian Aerospace Forces finally entered the R-77-1 (AA-12B) into service in 2015. It was subsequently deployed by Su-35S fighters in Syria on combat air patrols. The export model of the R-77-1 is called RVV-SD. Development Work on the R-77 began in 1982 by „Molnija OKB“ in Ukrainian SSR. After the dissolution of the Soviet Union the R-77 (Izdelie 170) missiles were produced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteor (missile)
The Meteor is a European Active radar homing, active radar guided Beyond Visual Range missile, beyond-visual-range air-to-air missile (BVRAAM) developed and manufactured by MBDA. It offers a multi-shot capability (multiple launches against multiple targets), and has the ability to engage highly maneuverable targets such as jet aircraft, and small targets such as UAVs and cruise missiles in a heavy electronic countermeasures (ECM) environment with a range far in excess of . A solid-fueled ramjet motor allows the missile to cruise at a speed of over Mach 4 and provides the missile with thrust and mid-course acceleration. A two-way data link enables the launch aircraft to provide mid-course target updates or retargeting if required, including data from other parties. The data link can transmit missile information such as functional and kinematic status, information about multiple targets, and notification of target acquisition by the seeker.

AIM-260 JATM
The AIM-260 Joint Advanced Tactical Missile (JATM) is an American beyond-visual-range air-to-air missile (BVRAAM) being developed and produced by Lockheed Martin. Designed to address advanced threats, the missile is expected to replace or supplement the AIM-120 AMRAAM currently in US service. The United States Department of Defense (DoD) considers the AIM-260A JATM program to be the number one air-delivered weapon priority for both the U.S. Air Force (USAF) and the Navy (USN); and its acquisition out-prioritizes other weapon system improvements and modernization efforts on any fielded aircraft. This program differs from the Long-Range Engagement Weapon being developed by Raytheon. The JATM is also separate from the AIM-174B, also developed by Raytheon for the USN. Development Initial launch platforms were expected to be, and currently are, the U.S. Air Force F-22 Raptor and the U.S. Navy F/A-18E/F Super Hornet, with integration with the F-35 Lightning II and F-15EX Eagle II b ...
