Aerospace
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as NASA, National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space Re ...

Piasecki VZ-8 Airgeep
The Piasecki VZ-8 Airgeep (company designation PA-59) was a prototype vertical takeoff and landing (VTOL) aircraft developed by Piasecki Aircraft. The Airgeep was developed to fulfill a U.S. Army Transportation Research Command contract for a flying jeep in 1957. The flying jeep was envisioned to be smaller and easier to fly than a helicopter. Design and development To meet the US Army's requirement, Piasecki's design featured two tandem, three-blade ducted rotors, with the crew of two seated between the two rotors. Power was by two Lycoming O-360-A2A piston engines, driving the rotors by a central gearbox. The first of two aircraft ordered by the Army, initially designated the Model 59K Skycar (and later renamed Airgeep) by Piasecki and designated VZ-8P by the Army, flew on 22 September 1958.Harding 1998, p.11.PA-59K: ''Histor ...

Telemedicine And Advanced Technology Research Center (United States Army)
The Telemedicine and Advanced Technology Research Center (TATRC) performs medical reconnaissance and special operations to address critical gaps that are underrepresented in DoD medical research programs. TATRC is an office of the headquarters of the US Army Medical Research and Materiel Command (USAMRMC). Commanders of TATRC and its precursors History The need for a TATRC- like organization was recognized as early as 1990, when the Army and Air Force medical departments wanted to jointly develop, procure, and deploy a filmless medical diagnostic imaging system (MDIS), at a time when such a system did not exist. On 1 November 1991, Lieutenant Colonel Fred Goeringer was assigned as the MDIS project officer, and by 1993, under his leadership the Navy had also joined this effort and a formal organization, the Medical Advanced Technology Management Office (MATMO) was established. MATMO, as it was referred to, became better known as the DOD “Telemedicine Test Bed” after the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Future Vertical Lift
Future Vertical Lift (FVL) is a plan to develop a family of military helicopters for the United States Armed Forces. Five different sizes of aircraft are to be developed, sharing common hardware such as sensors, avionics, engines, and countermeasures. The U.S. Army has been considering the program since 2004. FVL is meant to develop replacements for the Army's UH-60 Black Hawk, AH-64 Apache, CH-47 Chinook, and OH-58 Kiowa helicopters. The precursor for FVL is the Joint Multi-Role (JMR) helicopter program. Overview Summary After a decade of combat from Operation Iraqi Freedom and Operation Enduring Freedom, the U.S. Department of Defense found that the U.S. Army's rotorcraft fleet was wearing out. Combat operations made the helicopters fly five times more often than in peacetime. Manufacturers have been remanufacturing and upgrading existing families of aircraft without creating original platforms. The Future Vertical Lift (FVL) concept is to create a new rotorcraft that uses n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piasecki X-49
The Piasecki X-49 "SpeedHawk" is an American four-bladed, twin-engined experimental high-speed compound helicopter developed by Piasecki Aircraft. The X-49A is based on the airframe of a Sikorsky YSH-60F Seahawk, but utilizes Piasecki's proprietary vectored thrust ducted propeller (VTDP) design and includes the addition of lifting wings. The concept of the experimental program was to apply the VTDP technology to a production military helicopter to determine any benefit gained through increases in performance or useful load. "SpeedHawk" is a concept aircraft based on applying X-49A compounding concepts to a production UH-60 Black Hawk offering better performance, range, and increases in useful load. The "SpeedHawk" aircraft includes an SPU (third engine), high forward-swept wing concept, a 45-inch "fuselage plug" cabin extension, and several other drag reducing and performance-oriented improvements, including a rotor hub fairing, landing gear streamlining, and a fly-by-wire fligh ...

Autogyro
An autogyro (from Greek and , "self-turning"), also known as a ''gyroplane'', is a type of rotorcraft that uses an unpowered rotor in free autorotation to develop lift. Forward thrust is provided independently, by an engine-driven propeller. While similar to a helicopter rotor in appearance, the autogyro's rotor must have air flowing across the rotor disc to generate rotation, and the air flows upwards through the rotor disc rather than down. The autogyro was invented by Spanish engineer Juan de la Cierva in an attempt to create an aircraft that could fly safely at low speeds. He first flew one on 9 January 1923, at Cuatro Vientos Airfield in Madrid. The aircraft resembled the fixed-wing aircraft of the day, with a front-mounted engine and propeller. Cierva's autogyro is considered the predecessor of the modern helicopter. The success of the autogyro garnered the interest of industrialists and under license from Cierva in the 1920s and 1930s, the Pitcairn & Kellett compan ...

Frank Piasecki
Frank Nicolas Piasecki ( ; ; October 24, 1919 – February 11, 2008) was an American engineer and helicopter aviation pioneer. Piasecki pioneered tandem rotor helicopter designs and created the compound helicopter concept of vectored thrust using a ducted propeller. Early life and education Born in Philadelphia, Pennsylvania to an immigrant Polish tailor, Piasecki worked for autogyro manufacturers while still attending Overbrook High School, then studied mechanical engineering at the University of Pennsylvania before graduating with a bachelor's degree from New York University. He was employed by the Platt-LePage Aircraft Company as a control engineer on their XR-1 twin-rotor project. In 1940, he formed PV Engineering Forum with former Pennsylvania classmate Harold Venzie. He built a single-person, single-rotor helicopter designated the PV-2 and flew it on April 11, 1943. This helicopter impressed the United States Navy sufficiently to win Piasecki a development contract. Care ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Tr ...
