Brief overview of the technology and its uses


The Volerian concept is derived from the most evolved form of flight on earth: flapping.

The flapping action of a wing creates a stream of thrust producing vortices known as a reverse Kármán vortex street.


In nature, flapping consists of a heaving and pitching motion, however this action is mechanically complex and would add considerable weight and complexity.

By placing the flapping wing close to a specially shaped wall, in the form of a duct, the level of thrust can be efficiently increased without the need for greater amplitude (which would require an additional heaving motion) or an increase in flapping frequency.

The separation of the flapping wings by the duct walls allows the flapping frequency to be altered independently of adjacent sets of wings thereby avoiding the random fluctuations in thrust that would otherwise occur (due to the extent to which the flapping adjacent wings are in or out of phase with each other). Frequency changes can be used to control the aircraft and to help maintain efficient cruise conditions.


Volerian propulsion can be used in most situations where a propeller or fan would normally be used. This applies to both conventional and VTOL propulsion and to large and small aircraft.

In addition the system can be used for domestic and industrial fan applications and may have uses for water based propulsion.

The propulsive technology to create aircraft that are cheaper, quieter and safer than helicopters, large multicopters or current conventional aircraft will enable a far greater use of aircraft in almost all fields concerning transport including:

Military: especially for supply, medevac and operations on board ships such as ship to ship or ship to shore transport.

Commuting and urban travel: avoiding congestion for greater speed and economy.

House location: city housing locations and transport infrastructure become less relevant with greater ease of air travel.

Tourism: viewing sites of natural or historical interest, easier access to islands or hard to access sites.

First responders: police, medics, coast guards and fire brigades will all have a faster form of cheap, safe, quiet transport available to more service people for a wider range of uses.

Regional travel: the combination of VTOL and electric power will allow the use of a large number of automated landing and recharging sites that will enable the aircraft to travel much greater distances. Door to door travel times will be comparable to many regional jet aircraft routes, but without the discomfort and inconvenience.
