It was the first time the city of Phoenix hosted such a workshop, making it the latest U.S. city pledging to make flying friendlier for people with dementia. Over 14 million people are expected to ...
A human-powered aircraft (HPA) is an aircraft belonging to the class of vehicles known as human-powered transport.. As its name suggests, HPAs have the pilot not only steer, but power the aircraft (usually propeller-driven) by means of a system similar to a bicycle or tricycle: a pair of pedals, moved by the pilot's feet that turns a gear, which then moves a bicycle chain, which then rotates a ...
Powered parachutes have operated in an observation platform role by police departments, and have assisted with suspect captures, river rescues, critical infrastructure over-flights, crime scene photos, narcotics enforcement and crime suppression, at a small fraction of the cost of a police helicopter. In one case, this low-cost aviation asset ...
The room was about 22 yards (20 m) long and from 10 to 12 feet (3.7 m) high. The inclined wire for starting the machine occupied less than half the length of the room and left space at the end for the machine to clear the floor. In the first experiment the tail was set at too high an angle, and the machine rose too rapidly on leaving the wire.
A Carter PAV from 2014. A personal air vehicle (PAV) is a proposed class of passenger aircraft providing on-demand air transport.. The emergence of this alternative to traditional ground transport methods has been enabled by unmanned aerial vehicle technologies and electric propulsion.

He patented his "Improved Flying Machine" on 12 March 1878 (Patent No. 201200). [2] The aircraft consisted of a brass frame put together at ...
The WEAV uses a multitude of small electrodes covering the whole wetted area of the aircraft, in a multi-barrier plasma actuator (MBPA) arrangement, an enhancement over dual-electrode dielectric barrier discharge (DBD) systems using multiple layers of dielectric materials and powered electrodes.
