Ion wind, ionic wind, corona wind or electric wind is the airflow of charged particles induced by electrostatic forces linked to corona discharge arising at the tips of some sharp conductors (such as points or blades) subjected to high voltage relative to ground.

2018年11月21日 · A new MIT plane is propelled via ionic wind. Batteries in the fuselage (tan compartment in front of plane) supply voltage to electrodes (blue/white horizontal lines) strung along the length of the plane, generating a wind of ions that propels the plane forward.

The ionic wind is the creation of movement of air, or other fluids, by means of a corona discharge. It was studied scientifically as long ago as 1899 by Chattock (Ref. 1), although its existence was known even before that.

2018年2月7日 · In a new paper published in Nature Communications, a team of researchers from South Korea and Slovenia has experimentally investigated how ionic wind is caused when charged particles collide...

2019年7月16日 · Breakthrough flight -- Adrian Ieta, of SUNY Oswego’s electrical and computer engineering faculty, and the SUNY Research Foundation have applied for a patent for technology that resulted in a...

2018年11月21日 · Behind a thin white veil separating his makeshift lab from joggers at a Massachusetts Institute of Technology indoor track, aerospace engineer Steven Barrett recently test-flew the first-ever...

2018年11月21日 · Ionic wind is instead generated by a high-voltage electric field around a positively charged wire, called an emitter. The electricity, often supplied by batteries, makes electrons in the air...

2018年11月21日 · Instead of propellers or turbines, the light aircraft is powered by an “ionic wind” — a silent but mighty flow of ions that is produced aboard the plane, and that generates enough thrust to propel the plane over a sustained, steady flight.

2013年4月3日 · If enough voltage is applied, the resulting wind can produce a thrust without the help of motors or fuel. This phenomenon, called electrohydrodynamic thrust — or, more colloquially, “ionic wind” — was first identified in the 1960s.

2018年11月21日 · When charged molecules in the air are subjected to an electric field, they are accelerated. And when these charged molecules collide with neutral ones, they transfer part of their momentum, leading...
