“DeathWind” is a prototype next generation self contained rocket projectile designed for Military (primarily Naval) weapons usage. It is a blend of the MBAssociates 13mm “GYROJET” and the Russian “Shkval” torpedo designs combined with some “Coanda Effect” physics.
Design Concept Features:
Absolutely No Recoil
there is a slight negative recoil
as the projectile
actually tends to pull a vacuum in front of itself because of specific
design features and the “Coanda” effect.
First and Second generation prototypes shown here were made from surplus
.50BMG projectile jackets and various empty rifle shell casings. For
prototyping this served some basic purposes such as economy, proof of
concept and design, and finally to keep everything legal within the BATF
regulations. The igniter that is used is electrical in design with the
propulsion coming from a double base propellant vectored out midway up the
body creating a “Coanda effect” around the rear of the projectile thus
causing it to supercavitate. While these prototypes served to prove the
principles of the concept and basic design the .50BMG jackets were too
heavy to provide the performance desired. The third generation dealt with
a redesign to lighten the projectile while retaining the same basic
Fifth generation ( Fall 2004 ) is a modified 12.7mm percussion primed “DeathWind
projectile that will function and fire in the original MBA 13mm “Gyrojet”
guns, thus creating the “DeathWind Gyrojet”. Design and prototyping are near completion
and we are currently making sure it will fly with the BATF and are
designing production tooling. With luck we plan on having product becoming
available to the 13mm Gyrojet owners within one year.
We would greatly appreciate any contributions of information or copies of old articles about the original MB Associates Gyrojet firearms and their ammunition.
We are in need of the use of advanced flow prediction software that will model the Coanda and supercavitation effects. Yes, I know what it cost, that’s why....I am looking for serious research and/or investment funding, preferably from the U.S. Navy and/or Air Force.
