Powered Paragliding
Powered paragliding, also known as paramotoring or PPG, is a form of ultralight aviation where the pilot wears a back-pack motor (a paramotor) which provides enough thrust to take off using a paraglider. It can be launched in still air, and on level ground, by the pilot alone — no assistance is required. In many countries, including the United States, powered paragliding is minimally regulated and requires no license. The ability to fly both low and slow safely, the "open" feel, the minimal equipment and maintenance costs, and the portability are claimed to be this type of flying's greatest merits. Powered paragliders usually fly between at altitudes from 'foot-dragging' up about to or more with certain permission. Due to the paramotor's slow forward speed and nature of a soft wing, it is risky to operate in high winds, turbulence, or intense thermal activity, especially for inexperienced pilots. The paramotor, weighing from is supported by the pilot during takeoff. A ... [...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 ...

Association Of The United States Army
The Association of the United States Army (AUSA) is a private, non-profit organization that serves as the professional association of the United States Army. Founded in 1950, it has 121 chapters worldwide. Membership is open to everyone, not just Army personnel, nor is membership mandatory for soldiers. The organization publishes ''ARMY Magazine'' and the ''Green Book''. The current president is retired Army General Robert Brooks Brown. Membership Membership in AUSA is open to all Army ranks and all components are represented--including Regular Army, National Guard, Army Reserve, Government Civilians, Retirees, Wounded Warriors, Veterans, concerned citizens and family members. AUSA welcomes anyone who subscribes to the philosophy of a strong national defense with special concern for the Army. Community businesses and defense industry companies are also vital and contributing members of AUSA. Other membership categories include Community Partners and National Partners (for def ...

Parafoil
A parafoil is a nonrigid (textile) airfoil with an aerodynamic cell structure which is inflated by the wind. Ram-air inflation forces the parafoil into a classic wing cross-section. Parafoils are most commonly constructed out of ripstop nylon. The device was developed in 1964 by Domina Jalbert (1904–1991). Jalbert had a history of designing kites and was involved in the development of hybrid balloon-kite aerial platforms for carrying scientific instruments. He envisaged the parafoil would be used to suspend an aerial platform or for the recovery of space equipment. A patent was granted in 1966. Deployment shock prevented the parafoil's immediate acceptance as a parachute. It was not until the addition of a drag canopy on the riser lines (known as a "slider") which slowed their spread that the parafoil became a suitable parachute. Compared to a simple round canopy, a parafoil parachute has greater steerability, will glide further and allows greater control of the rate of desce ...

Domina Jalbert
Domina Cleophas Jalbert (1904–1991) invented the ram-air inflated flexible wing, often called the "Jalbert parafoil". Personal life Domina Jalbert was born in Saint-Jean-de-Matha, Quebec, Canada; his father was Onesime Jalbert (1856–1938) and his mother was Celestine Gouger (1861–1939). He was one of 17 children. Early in his life he moved to Woonsocket, Rhode Island, where he lived and worked for many years before moving to Boca Raton, Florida, in his older years. While living in Woonsocket, Jalbert graduated from Woonsocket High School, and later worked as a track coach and administrator for Mount St. Charles Academy. Jalbert received a U.S. pilots' license in 1927. In the 1930s he was active in kiting, using large kites for advertising purposes. He was hired to help protect the coastline of the western United States during war with the design and making of barrage balloons; he worked for the United States Rubber Company in Naugatuck, Connecticut, USA.

Atair Micro LEAPP
Altair is the brightest star in the constellation of Aquila and the twelfth-brightest star in the night sky. It has the Bayer designation Alpha Aquilae, which is Latinised from α Aquilae and abbreviated Alpha Aql or α Aql. Altair is an A-type main-sequence star with an apparent visual magnitude of 0.77 and is one of the vertices of the Summer Triangle asterism; the other two vertices are marked by Deneb and Vega. It is located at a distance of from the Sun. Altair is currently in the G-cloud—a nearby interstellar cloud, an accumulation of gas and dust. Altair rotates rapidly, with a velocity at the equator of approximately 286 km/s.From values of ''v'' sin ''i'' and ''i'' in the second column of Table 1, Monnier et al. 2007. This is a significant fraction of the star's estimated breakup speed of 400 km/s. A study with the Palomar Testbed Interferometer revealed that Altair is not spherical, but is flattened at the poles due to it ...

Paragliders
Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying, foot-launched Glider (aircraft), glider aircraft with no rigid primary structure. The pilot sits in a :wikt:harness, harness or lies supine in a cocoon-like 'pod' suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside. Despite not using an engine, paraglider flights can last many hours and cover many hundreds of kilometres, though flights of one to two hours and covering some tens of kilometres are more the norm. By skillful exploitation of sources of lift (soaring), lift, the pilot may gain height, often climbing to altitudes of a few thousand metres. History In 1966, Canadian Domina Jalbert was granted a patent for a ''multi-cell wing type aerial device—''"a wing having a flexible canopy constituting an upper s ...
