Vampire Drones
Baba Yaga is the nickname for a number of Ukrainian heavy bomber drones used during the 2022 Russian invasion of Ukraine. Several models are referred as Baba Yaga, including Aerorozvidka R18, , Nemesis and . Nickname "''Baba Yaga''" is a reference to the Slavic mythological creature ''Baba Yaga'', a supernatural witch who flies around in a cauldron or mortar. In August 2023, The Daily Beast reported that Chechen soldiers of the Russian armed forces claimed the drone had claws and could abduct soldiers.

Ukraine
Ukraine ( uk, Україна, Ukraïna, ) is a country in Eastern Europe. It is the second-largest European country after Russia, which it borders to the east and northeast. Ukraine covers approximately . Prior to the ongoing Russian invasion, it was the eighth-most populous country in Europe, with a population of around 41 million people. It is also bordered by Belarus to the north; by Poland, Slovakia, and Hungary to the west; and by Romania and Moldova to the southwest; with a coastline along the Black Sea and the Sea of Azov to the south and southeast. Kyiv is the nation's capital and largest city. Ukraine's state language is Ukrainian; Russian is also widely spoken, especially in the east and south. During the Middle Ages, Ukraine was the site of early Slavic expansion and the area later became a key centre of East Slavic culture under the state of Kievan Rus', which emerged in the 9th century. The state eventually disintegrated into rival regional powers and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chechens
The Chechens (; ce, Нохчий, , Old Chechen: Нахчой, ''Naxçoy''), historically also known as ''Kisti'' and '' Durdzuks'', are a Northeast Caucasian ethnic group of the Nakh peoples native to the North Caucasus in Eastern Europe. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea with its outlets, the Bosporus and Dardanelles." They refer to themselves as Nokhchiy (pronounced ; singular Nokhchi, Nokhcho, Nakhchuo or Nakhtche). The vast majority of Chechens today are Muslims and live in Chechnya, a republic of Russia. The North Caucasus has been invaded numerous times throughout history. Its isolated terrain and the strategic value outsiders have placed on the areas settled by Chechens has contributed much to the Chechen community ethos and helped shape its national character. Chechen society has traditionally been e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Starlink
Starlink is a satellite internet constellation operated by SpaceX, providing satellite Internet access coverage to 45 countries. It also aims for global mobile phone service after 2023. SpaceX started launching Starlink satellites in 2019. As of December 2022, Starlink consists of over 3,300 mass-produced small satellites in low Earth orbit (LEO), which communicate with designated ground transceivers. In total, nearly 12,000 satellites are planned to be deployed, with a possible later extension to 42,000. SpaceX announced reaching more than one million subscribers in December 2022. The SpaceX satellite development facility in Redmond, Washington houses the Starlink research, development, manufacturing, and orbit control teams. The cost of the decade-long project to design, build, and deploy the constellation was estimated by SpaceX in May 2018 to be at least US$10 billion. SpaceX expects more than $30 billion in revenue by 2025 from its satellite constellation, while revenues ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octocopter
A multirotor or multicopter is a rotorcraft with more than two lift-generating rotors. An advantage of multirotor aircraft is the simpler rotor mechanics required for flight control. Unlike single- and double-rotor helicopters which use complex variable pitch rotors whose pitch varies as the blade rotates for flight stability and control, multirotors often use fixed- pitch blades; control of vehicle motion is achieved by varying the relative speed of each rotor to change the thrust and torque produced by each. Due to their ease of both construction and control, multirotor aircraft are frequently used in radio control aircraft and unmanned aerial vehicle (UAV) (drone) projects in which the names tricopter, quadcopter, hexacopter and octocopter are frequently used to refer to 3-, 4-, 6- and 8-rotor rotorcraft, respectively. There is also the X8 (also called ''octo-quad'') configuration that is similar to the quadracopter design, except that it has eight rotors; the lower of whi ...

Agricultural Drone
An agricultural drone is an unmanned aerial vehicle used in agriculture operations, mostly in yield optimization and in monitoring crop growth and crop production. Agricultural drones provide information on crop growth stages, crop health, and soil variations. Multispectral sensors are used on agricultural drones to image electromagnetic radiation beyond the visible spectrum, including near-infrared and short-wave infrared. Legality As drones entered use in agriculture, the Federal Aviation Administration (FAA) encouraged farmers to use this new technology to monitor their fields. However, with the unexpected boom of agricultural drones, the FAA quickly retracted such encouragement, pending new rules and regulations. With incidents such as drones crashing into crop dusters, the FAA and the AFBF (American Farm Bureau Federation) began discussions to agree on regulations that would allow the beneficial use of such drones in a safe and efficient manner. In 2016, the FAA published ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quadcopter
A quadcopter or quadrotor is a type of helicopter with four rotors. Although quadrotor helicopters and convertiplanes have long been flown experimentally, the configuration remained a curiosity until the arrival of the modern UAV or drone. The small size and low inertia of drones allows use of a particularly simple flight control system, which has greatly increased the practicality of the small quadrotor in this application. Design principles Each rotor produces both lift and torque about its center of rotation, as well as drag opposite to the vehicle's direction of flight. Quadcopters generally have two rotors spinning clockwise (CW) and two counterclockwise (CCW). Flight control is provided by independent variation of the speed and hence lift and torque of each rotor. Pitch and roll are controlled by varying the net centre of thrust, with yaw controlled by varying the net torque. Unlike conventional helicopters, quadcopters do not usually have cyclic pitch control, in wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First-person View (radio Control)
First-person view (FPV), also known as remote-person view (RPV), or simply video piloting, is a method used to control a radio-controlled vehicle from the driver or pilot's view point. Most commonly it is used to pilot a radio-controlled aircraft or other type of unmanned aerial vehicle (UAV). The vehicle is either driven or piloted remotely from a first-person perspective via an onboard camera, fed wirelessly to video FPV goggles or a video monitor. More sophisticated setups include a pan-and-tilt gimbaled camera controlled by a gyroscope sensor in the pilot's goggles and with dual onboard cameras, enabling a true stereoscopic view. Airborne FPV Airborne FPV is a type of remote-control (RC) flying that has grown in popularity in recent years. It involves mounting a small video camera and an analogue video transmitter to an RC aircraft and flying by means of a live video down-link, commonly displayed on video goggles or a portable monitor. FPV became increasingly common throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Daily Beast
''The Daily Beast'' is an American news website focused on politics, media, and pop culture. It was founded in 2008. It has been characterized as a "high-end tabloid" by Noah Shachtman, the site's editor-in-chief from 2018 to 2021. In a 2015 interview, former editor-in-chief John Avlon described the ''Beast''s editorial approach: "We seek out scoops, scandals, and stories about secret worlds; we love confronting bullies, bigots, and hypocrites." In 2018, Avlon described the ''Beast''s "strike zone" as "politics, pop culture, and power". History ''The Daily Beast'' began publishing on October 6, 2008. Its founding editor was Tina Brown, a former editor of ''Vanity Fair'' and ''The New Yorker'' as well as the short-lived ''Talk'' magazine. The name of the site was taken from a fictional newspaper in Evelyn Waugh's novel ''Scoop''. In 2010, ''The Daily Beast'' merged with the magazine ''Newsweek'' creating a combined company, The Newsweek Daily Beast Company. The merge ...

Baba Yaga
In Slavic folklore, Baba Yaga, also spelled Baba Jaga (from Polish), is a supernatural being (or one of a trio of sisters of the same name) who appears as a deformed and/or ferocious-looking woman. In fairy tales Baba Yaga flies around in a mortar, wields a pestle, and dwells deep in the forest in a hut usually described as standing on chicken legs. Baba Yaga may help or hinder those that encounter or seek her out and may play a maternal role; she has associations with forest wildlife. According to Vladimir Propp's folktale morphology, Baba Yaga commonly appears as either a donor or a villain, or may be altogether ambiguous. Dr. Andreas Johns identifies Baba Yaga as "one of the most memorable and distinctive figures in eastern European folklore", and observes that she is "enigmatic" and often exhibits "striking ambiguity". Johns summarizes Baba Yaga as "a many-faceted figure, capable of inspiring researchers to see her as a Cloud, Moon, Death, Winter, Snake, Bird, Pelican ...

Slavs
Slavs are the largest European ethnolinguistic group. They speak the various Slavic languages, belonging to the larger Balto-Slavic language, Balto-Slavic branch of the Indo-European languages. Slavs are geographically distributed throughout northern Eurasia, mainly inhabiting Central Europe, Central and Eastern Europe, and the Balkans to the west; and Siberia to the east. A large Slavic minority is also scattered across the Baltic states and Central Asia, while a substantial Slavic diaspora is found throughout the Americas, as a result of immigration. Present-day Slavs are classified into East Slavs (chiefly Belarusians, Russians, Rusyns, and Ukrainians), West Slavs (chiefly Czechs, Kashubians, Poles, Slovaks and Sorbs) and South Slavs (chiefly Bosniaks, Bulgarians, Croats, Macedonians (ethnic group), Macedonians, Montenegrins, Serbs and Slovenes). The vast majority of Slavs are traditionally Christians. However, modern Slavic nations and ethnic groups are considerably dive ...
