Measure of MS A Success:
5-1000 metersDefilade, Open, Covered, EnclosedLiquid, Powder, Aerosol, ObjectsPoint =550, Area=1000With PH given for certain radius.• Scalability to other size rounds• All weather• Gun/Ammo interface identification• Operate same as lethal round
* Component and/or breadboard validation in a relevant environment
• LIDAR proximity sensor (LPS) and controlled terminal deceleration for thedeployment of an incapacitating agent.•LPS located in the nose of the shell will initiate payload deployment at a pre-determined range from the target.• Array of variable force-reversing thrusters will fire to decelerate the projectile to anon-lethal velocity and simultaneously release the payload. The force of the reversingthrusters may be adjusted to match the changing projectile velocity. In addition, theejection of the NL payload will be used to provide a portion of the deceleration force.

• The bursting charge projects the non-lethal payload of liquids/powders/aerosols/solids and a densepowder mass.• The forward momentum of the non-lethal payload and dense powder mass reduce the forwardmomentum and kinetic energy of the residual projectile to a non-lethal level (“Davis Gun concept”).• The high aerodynamic drag of the dense powder allows the kinetic energy of the dense powder payloadto be rapidly dissipated.•The aerodynamic characteristics of the non-lethal payload and the burst point from the target provide thenon-lethal delivery of the non-lethal payload.•Projectile mass, velocity, recoil impulse and trajectory are matched to the lethal projectile for Fire Controlcompatibility and reliable weapon function.

Modeling Results• Effective Dosage vs. Coverage Area:
– The numbers appearing to the right of each bubble are the corresponding coverage area in m2.As expected, the coverage area decreases with increasing dosage level and decreasing time.The Traditional ECt50 dosage (10mg-min/m3), has historically been used as a ‘worst case’ andrelates to highly motivated individuals who may be less susceptible to the effects of CS. Thesuitability of any of these rounds depends on the desired interpretation of incapacitation andeffectiveness..

Modeling Results• Multiple rounds vs. Coverage Area:
– As expected, multiple rounds increases the coverage area.– The 40mm grenades’ coverage is greater than the OICW by a factor of 4-7, but this
ignores their greater weights (~3.5x OICW).– On an equal-weight basis, differences are significantly less substantial.
