SPORT ejectors

TENNIS

The air ejectors serving TENNIS are no mechanical moving parts devices powered by an external high pressure & low flow blowers or portable compressed air tank/bottle. The main applications are at the tennis robot and tennis ball collector. We are studying the possibility to have air drone that shoot tennis ball from any positions down and up, at natural level of human. The movement of the flying tennis robot needs to be as fast as the real human. (photo www.squaremeal.co.uk)
Usual ejector types for this application are:

ARENA

The air ejectors serving ARENAS are no mechanical moving parts devices powered by an external high pressure & low flow blowers or mobile screw compressed air. The main applications are at the air movements near the grass level in order to dry the grass area for arena maintenance and also to the ventilation during the competition having full capacity of humans by creating smart air flow that get fresh oxygen in any part of the arena.

PARACHUTING

The air ejectors serving PARACHUTING domain are no mechanical moving parts devices powered by an external high pressure & low flow blowers or mobile screw compressed air. The main applications are at the vertical wind tunnels and indoor skydiving for training and fun. Wind tunnel velocities are between 27-35 m/s and efficiency will be higher when the tunnel has closed loop. The tunnel is safer having no vibration because the system has no rotor/blades.
