S-TEC Sentry
The S-TEC Sentry is a reconnaissance unmanned aerial vehicle (UAV) (or drone), developed in the United States in the 1980s. Built by S-TEC systems of Texas (now part of DRS Unmanned Technologies), it is a battlefield mini-UAV in roughly the same class as the BAI Dragon drone. In fact, the Sentry looks something like an Exdrone with a twin-boom raised tail. It is built of carbon composition and Kevlar, and powered by a 19.5 kW (26 hp) piston engine in a tractor configuration. S-TEC's main business is building autopilots for civil aviation, and small UAVs were a logical extension of that business. S-TEC introduced the Sentry in 1986, and has sold over 130 since that time. Launch is via a wheeled dolly or pneumatic catapult, and recovery via parasail or on skid landing gear. In an interesting experiment, the company has experimented with carriage of the BLU-108 Sensor Fuzed Weapon (SFW) anti-armor submunition on the Sentry. After release in a target area, the cylindric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

S-TEC Corporation
S-TEC Corporation is a United States corporation that was founded in 1978 and is headquartered in Mineral Wells, Texas. It manufactures flight control systems for the General Aviation aftermarket and for a number of original equipment manufacturers. S-TEC is the leader in the general aviation autopilot market for small- and mid-sized planes. Customers Genesys Aerosystems has a number of forward-fit autopilot customers including Pilatus, Indonesian Aerospace, Epic Aircraft, and Aviat Aircraft. Their latest autopilot, the S-TEC 3100, has earned Supplemental Type Certificate (STC) on over 100 aircraft models. History Meggitt acquired S-TEC and S-TEC Unmanned Technologies (SUTI) for $24 million in 2000. (DRS Technologies purchased the UAV business from Meggitt in 2002 but later closed the Mineral Wells facility.) S-TEC was purchased for $38 million by Cobham plc in 2008. In April 2014, Cobham sold Chelton Flight Systems and S-TEC Corporation to Genesys Aerosystems. Products Avion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BQM-147 Dragon
__NOTOC__ The BAI Aerosystems (BAIA) BQM-147 Dragon unmanned aerial vehicle is a tactical battlefield UAV operated by the US Marine Corps. Development The Dragon began life in 1986, when the US Marines Corps contracted with the Applied Physics Laboratory (APL), an offshoot of Johns Hopkins University in Baltimore, Maryland, that works on government technology development contracts, to build a small piston-powered UAV as an "expendable jammer" for battlefield electronics warfare. The program was logically named "ExJam". BAI Aerosystems was a subcontractor to APL and provided airframe parts. "Creeping featurism" infected the program as the Marines considered more applications for the little drone, and in 1987 the program was given the new name of BQM-147A "Expendable Drone" or "Exdrone". The communications-jammer configuration of the vehicle was tested in the University of Maryland Glenn L. Martin wind tunnel, and successfully completed developmental flight testing at Naval Air S ...

Kevlar
Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. It is typically spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components. Kevlar has many applications, ranging from bicycle tires and racing sails to bulletproof vests, all due to its high tensile strength-to-weight ratio; by this measure it is five times stronger than steel. It is also used to make modern marching drumheads that withstand high impact; and for mooring lines and other underwater applications. A similar fiber called Twaron with the same chemical structure was developed by Akzo in the 1970s; commercial production started in 1986, and Twaron is now manufactured by Teijin.

BLU-108 Sensor Fuzed Weapon
The BLU-108 is an air-delivered submunition, containing four further smart "Skeet" warheads. The system is manufactured by Textron Systems Weapon & Sensor Systems since 1992. The BLU-108 is released from a munitions dispenser, with a parachute being used to slow its descent. It then fires the four rapidly rotating skeets, which use multi-mode optical sensors to identify a variety of targets ranging from tanks and missile launchers to railway locomotives and landed aircraft. When the skeet passes over what it considers a high priority target (this priority can be changed prior to employment), it fires a 0.9 kg (2 lb) explosively formed penetrator providing armor-piercing and incendiary effects, as well as a fragmentation ring meant to damage any soft targets, primarily enemy persons, in the immediate vicinity of the target. BLU-108/B specifications * Length: 78.8 cm (31.0 in) * Diameter: 13.3 cm (5.25 in) * Maximum lateral dimension: 18.4 cm (7.25 in ...

Unmanned Aerial Vehicles 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) ...
