EHD Thruster Collection

Horizontal plane foil thruster - tested 18/05/02


Shown above is my horizontal plane foil thruster. The top wire is spirally wound. As expected, the thrust generated by the impact momentum of the ions and air molecules hitting the foil is cancelling out all the thrust, and the thruster exerts a zero net force on the surrounding air. Also, it is highly probable that the audible noise is the impact of millions of air ions hitting the foil - sound is more like sandblasting than wind blowing. This confirms that ion-air interaction during their acceleration towards the foil contribute more or less to all of the thrust. Current consumption is higher than the simple thruster types due to its geometry.


Horizontal plane grid ionocraft - tested 10/01/04


The EHD device shown above has much in common with the De Severski Ionocraft, designed in the 60's. It is basically similar to the first plane foil type, but with a great important difference in air flow. The fine grid has the ability of electric field melding and thus its resulting electric field is the same as a plane foil. The main difference is in its hydrodynamics effect upon the flowing air. In this case, since the grid allows air to pass through with minimum drag, the momentum is not lost and thrust output is re-gained. The wire to plane grid shown above weighs 4 grammes and is shown floating in air at a supply voltage of 33kV.
