Electron Wind Generator - Ventilation System Statement of Work
-------------------------------------------------------------------------------
STATEMENT OF WORK
CONTRACTOR: High Voltage Integrated
INTRODUCTION
The Electron Wind Generator (EWG) creates air movement without moving parts. It
operates by applying a high voltage potential between sets of electrodes that
are introduced into the cross section of the ventilation ductwork as shown
conceptually in Figure 1 below. As air passes through the electrodes, a high
density of ions is created. The High Voltage Power Supply (HVPS) applies a
potential between the corona electrode and the accelerating electrode that
causes the ions to move. As the ions collide with the air molecules, they cause
an overall movement to the right. This effect is known as "electron wind" and
can be used to generate gas flow velocity of about 700 feet per minute. The
airflow velocity is completely adjustable from zero to the maximum by
controlling the electrode voltage. Reversing the electrode voltage can also
reverse flow direction. The accelerating electrode neutralizes the gas ions
resulting in airflow with negligible ozone content.

FIGURE 1. EWG CONCEPT. THE EWG COMBINES AIR MOVEMENT AND PURIFICATION.
The EWG performs two functions in addition to creating air movement. The corona
field, the ions, and the small amount of ozone created have been proven to kill
bacteria and are expected to oxidize chemical contaminants such as carbon
monoxide, hydrogen, and hydrocarbons. In addition, it has been demonstrated that
the EWG precipitates dust particles - a function currently performed by
electrostatic precipitators. Figure 1 shows a separate removable and cleanable
dust-collecting electrode that could be added to perform this function.
The EWG offers many potential ventilation system advantages including:
o The EWG can be designed in many shapes and sizes and has extremely low
weight facilitating distribution in ventilation ducting throughout the
ship.
================================================================================
o The adjustable flow velocity and reversibility of the EWG can support
increased damage control automation and fight-while-hurt capability.
o The dust removal and air purification capability of the EWG can reduce
ventilation system components, increase ship cleanliness, and assist in
damage control efforts.
o The virtually silent operation of the EWG can reduce the ship acoustic
signature while eliminating most of the sound mounting currently required
by the ventilation system.
Innovative new ventilation system designs are required to realize the full
benefits of the EWG. An electron wind generator ventilation system (EWG-VS)
design should be modular and adaptive with significantly increased
affordability, maintainability, and survivability. There is a need to examine
the full range of design options offered by the EWG and develop concepts for
innovative surface ship and submarine ventilation systems. These concept designs
will allow quantifying the benefits of EWG-VS as compared to conventional
designs to support ONR ventilation system development. The design work will also
identify critical technical issues for EWG deployment and any development
efforts required.
REQUIRED EFFORT
The contractor shall work as part of a design team developing concepts for
innovative surface ship and submarine ventilation systems that take advantage of
the EWG's light weight, controllability, configuration flexibility, and
purification capability. The contractor shall provide measured and projected
performance data for the EWG as required by the team. The contractor shall also
provide ideas on highly modular and adaptive systems with significantly
increased affordability, maintainability, and survivability for evaluation by
the team.
SCHEDULE AND MILESTONES
Figure 2 shows the schedule for this effort. The ventilation system concepts
shall be presented at a tailored SDR prior to the preparation of the final
report.
