Blade Air Mobility, Inc. (stylized as BLADE) is an aviation company headquartered in New York City and incorporated in Delaware. Blade's urban air mobility platform provides air transportation for passengers and last-mile critical cargo, [2] [3] primarily using helicopters and amphibious aircraft for passenger routes in the United States, Canada, Southern Europe, and India, in addition to ...
Tokyo Metropolitan Police Department EH101 (AW101) The BERP rotor blade design was developed under the British Experimental Rotor Programme.The initial BERP rotor blades were developed in the late 1970s to mid-1980s as a joint venture programme between Westland Helicopters and the Royal Aircraft Establishment (RAE), with Professor Martin Lowson as a co-patentee.

A rotor blade produces more lift in the advancing half. As a blade moves toward the direction of flight, the forward motion of the aircraft increases the speed of the air flowing around the blade until it reaches a maximum when the blade is perpendicular to the relative wind. At the same time, a rotor blade in the retreating half produces less ...
Although quadrotor helicopters and convertiplanes have long been flown experimentally, the configuration remained a curiosity until the arrival of the modern unmanned aerial vehicle 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 ...
Ehang is a Chinese company that has developed numerous drones including passenger plane Ehang 184. EHang 184 was their first model, developed as an eight dual rotor wing blade drone that can carry two passengers. [11] The model was retired in 2020 and is replaced by the Ehang 216. Ehang also released a one passenger drone, Ehang 116. [12]
Police helicopters could be replaced with military-grade drones as part of a major tech upgrade across some forces in England and Wales.. Chairwoman of the Association of Police and Crime ...
[1] [2] Unlike fixed-wing aircraft, of which the stall occurs at relatively low flight speed, the dynamic stall on a helicopter rotor emerges at high airspeeds or/and during manoeuvres with high load factors of helicopters, when the angle of attack(AOA) of blade elements varies intensively due to time-dependent blade flapping, cyclic pitch and ...
