Boeing Persistent Munition Technology Demonstrator
The Persistent Munition Technology Demonstrator or PMTD is an unmanned aerial vehicle (UAV) developed and produced by the Advanced Weapons and Missile Systems division of Boeing as a test bed in order to further develop and flight test various UAV technologies. It has also been referred to as the Dominator. The PMTD weighs , has a wingspan and is powered by a single piston engine driving a pusher propeller. It was first flown in April, 2006, at Vandalia Municipal Airport, Vandalia, Illinois. Designed for either air or ground launch and high loiter times, the PMTD has the ability to operate completely autonomously. During its maiden flight, the UAV autonomously flew to 14 programmed locations, changed altitude four times, and met all programmed speeds. The initial set of flight tests focused solely on validation of the autonomous flight mode, while future tests will include sensor integration, weapon guidance systems, munitions dispensing systems and in-flight refueling.

C-17 Globemaster III
The McDonnell Douglas/Boeing C-17 Globemaster III is a large military transport aircraft that was developed for the United States Air Force (USAF) from the 1980s to the early 1990s by McDonnell Douglas. The C-17 carries forward the name of two previous piston-engined military cargo aircraft, the Douglas C-74 Globemaster and the Douglas C-124 Globemaster II. The C-17 is based upon the YC-15, a smaller prototype airlifter designed during the 1970s. It was designed to replace the Lockheed C-141 Starlifter, and also fulfill some of the duties of the Lockheed C-5 Galaxy. Compared to the YC-15, the redesigned airlifter differed in having swept wings, increased size, and more powerful engines. Development was protracted by a series of design issues, causing the company to incur a loss of nearly US$1.5 billion on the program's development phase. On 15 September 1991, roughly one year behind schedule, the first C-17 performed its maiden flight. The C-17 formally entered USAF service o ...

Unmanned Military Aircraft Of The United States
An uncrewed vehicle or unmanned vehicle is a vehicle without a person on board. Uncrewed vehicles can either be under telerobotic control—remote controlled or remote guided vehicles—or they can be autonomously controlled—autonomous vehicles—which are capable of sensing their environment and navigating on their own. Types There are different types of uncrewed vehicles: * Remote control vehicle (RC), such as radio-controlled cars or radio-controlled aircraft * Unmanned ground vehicle (UGV), such as the autonomous cars, or unmanned combat vehicles (UCGV) * Unmanned ground and aerial vehicle (UGAV), unmanned vehicle with hybrid locomotion methods * Unmanned aerial vehicle (UAV), unmanned aircraft commonly known as "drone" ** Unmanned combat aerial vehicle (UCAV) **Medium-altitude long-endurance unmanned aerial vehicle (MALE) ** Miniature UAV (SUAV) ** Delivery drone ** Micro air vehicle (MAV) ** Target drone * Autonomous spaceport drone ship * Uncrewed surface vehicle (USV) ...

2000s United States Experimental Aircraft
S, or s, is the nineteenth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Origin Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a phoneme, so the derived Greek letter sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ) "to hiss". The original name of the letter "sigma" may have been ''san'', but due to the complica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joint Direct Attack Munition
The Joint Direct Attack Munition (JDAM) is a guidance kit that converts unguided bombs, or "dumb bombs", into all-weather precision-guided munitions. JDAM-equipped bombs are guided by an integrated inertial guidance system coupled to a Global Positioning System (GPS) receiver, giving them a published range of up to . JDAM-equipped bombs range from . The JDAM's guidance system was jointly developed by the United States Air Force and United States Navy, hence the "joint" in JDAM. When installed on a bomb, the JDAM kit is given a GBU (Guided Bomb Unit) identifier, superseding the Mark 80 or BLU (Bomb, Live Unit) nomenclature of the bomb to which it is attached. The JDAM is not a stand-alone weapon; rather it is a "bolt-on" guidance package that converts unguided gravity bombs into precision-guided munitions (PGMs). The key components of the system consist of a tail section with aerodynamic control surfaces, a (body) Strake (aeronautics), strake kit, and a combined inertial guidance s ...

Unmanned Combat Air Vehicle
An unmanned combat aerial vehicle (UCAV), also known as a combat drone, colloquially shortened as drone or battlefield UAV, is an unmanned aerial vehicle (UAV) that is used for intelligence, surveillance, target acquisition, and reconnaissance and carries aircraft ordnance such as missiles, ATGMs, and/or bombs in hardpoints for drone strikes. These drones are usually under real-time human control, with varying levels of autonomy. Unlike unmanned surveillance and reconnaissance aerial vehicles, UCAVs are used for both drone strikes and battlefield intelligence. Aircraft of this type have no onboard human pilot. As the operator runs the vehicle from a remote terminal, equipment necessary for a human pilot is not needed, resulting in a lower weight and a smaller size than a manned aircraft. Many countries have operational domestic UCAVs, and many more have imported armed drones or are in the process of developing them. History One of the earliest explorations of the concep ...

Battlespace
Battlespace or battle-space is a term used to signify a unified military strategy to integrate and combine armed forces for the military theatre of operations, including air, information, land, sea, cyber and outer space to achieve military goals. It includes the environment, factors, and conditions that must be understood to successfully apply combat power, protect the force, or complete the mission. This includes enemy and friendly armed forces, infrastructure, weather, terrain, and the electromagnetic spectrum within the operational areas and areas of interest. Concept From "battlefield" to "battle-space" Over the last 25 years, the understanding of the military operational environment has transformed from primarily a time and space-driven linear understanding (a "battlefield") to a multi-dimensional system of systems understanding (a battle-space). This system of systems understanding implies that managing the battle-space has become more complex, primarily beca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth's Atmosphere
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in ...

Theater (warfare)
In warfare, a theater or theatre is an area in which important military events occur or are in progress. A theater can include the entirety of the airspace, land and sea area that is or that may potentially become involved in war operations. Theater of war In his book ''On War'', Carl von Clausewitz defines the term ''Kriegstheater'' (translating the older, 17th-century Latin term ''theatrum belli'') as one that: Theater of operations ''Theater of operations'' (TO) is a sub-area within a theater of war. The boundary of a TO is defined by the commander who is orchestrating or providing support for specific combat operations within the TO. Theater of operations is divided into strategic directions or military regions depending on whether it is a war or peacetime. The United States Armed Forces split into Unified Combatant Commands (regions) that are assigned to a particular theater of military operations. A strategic direction is a group of armies also known as a task (fie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
