'Silent' Black Helicopters
Alien Helos
(Still working on these guys. I took tid bits from various conspiracy games, notably
Illuminati from GURPs)
I was shooting for two types of craft. One that is the spiffy alien model, and another
that is just a high tech military chopper with sound cancellation ability (i'll try to
post the sound cancelling circuitry later on....its really simple!)
Craft #1 Alien Model
These craft are Saurian/Book in design.
This site contained information sensitive to the Saurian Sovereignty.
In accordance with UN Security Protocol 1998-23, all material related to a Saurian Stealth
Helicopter Design has been removed. The Saurian Government vows complete and total
vengence upon any who disobey.

Craft #2
The Military Model
Standard US Military Blackhawk, outfitted with newly designed rotors. The main
'quieting' feature is the lack of a rear tail rotor. With out this rotor, the noise
from the main blades is significantly reduced. This is due to the lack of air turbulence
produced by the rear rotors mixing with the turbulence produced by the main blades.
'Silent' is a relative term.
They do make noise. Just less than any rotarywing built to date. The Blackhawks have
also been outfitted with a noise cancellation system that samples the exterior noise and
inverts the signal 180 degrees. It then pipes the inverted signal back out (via external
speakers), the two signals cross and negate each other. (Guess what folks, the newer
Mercedes models will have a similar device attached to their mufflers...)
Available to any military, Intelligence, and Drug
agents
