Projectile firing device using liquified gas propellant

explosives - liquid CO2 (HVL-CO Technology)

Poly Systems has developed the HVL-CO Technology converting liquid CO2 into an explosive medium, providing negligible IR, low recoil, no muzzle flash/smoke telltale.

The ‘no end of muzzle flame' provides unique EODD/IEDD and mine clearance capabilities for terrestrial and marine circumvention by remote command. The low-heat discharge gives long barrel life under sustained firing with no during-operation barrel change requirement, and no artillery barrel droop.

Field testing of this unit has achieved 440 metres per second of a 7.62mm projectile at 14500 psi breech pressure.

Description	Pertinent information
HVL-CO technological capability has been demonstrated in a 7.62mm prototype. This system provides up to 70 weight saving over current weapons - negligible auditory/infrared/magnetic signatures or muzzle discharge tell-tale, very low vibration/recoil with an end of barrel efficiency of around 80. HVL-CO is applicable to all weapon calibres for aircraft, vessels and from handguns through tanks and artillery to Low Earth Orbit satellite launching. The HVL-CO projectile discharge offers high cyclic rates of fire using aerodynamic ammunition without the problems of residual heat build-up and barrel wear.	HVL-CO offers: enhanced weapon capabilities operable in urban and difficult terrain lightweight mortars offer greater sectional firepower and rapid mobility capabilities for artillery and armour unmanned artillery can be deployed and on command aimed, fired and reloaded from a remote HQ. Batteries of remote HVL-CO weapons without crews can be continuously fired (no barrel droop) for anti-missile defence. HVL-CO weapons are interoperable with in use electronics in-orbit on-platform HVL-CO weapons offer attack/defence capabilities while terrestrial payload launches are virtually non-detectable to intercontinental targets. HVL-CO ammunition is aerodynamic in design enhancing range and trajectory capabilities Australian Patent No. 2002336805: Also patented in Brazil, Canada, China, India, Israel, Japan, Korea, South Africa
Status	Company
Poly Systems has contracted with the Materials & Engineering Science Division of the Australian Nuclear Science & Technology Organisation for collaborative assistance in developing the HVL-CO weapon system capabilities. Rough order of magnitude cost and schedule: By conjunctively developing calibres, operational prototype weapons are capably deliverable within 12 months, per calibre costs range from $3,000,000. Deliverables: User's manual, user training program, servicing details, aerodynamic ammunition, low maintenance weapons with continuous cyclic rate of ‘cold' discharge operation under all climatic conditions.
