MANTARAYA Delta Challenger
Military & Rescue, missions.

MANTARAYA Delta Challenger is an only underwater propelling device, because the diver stays in the wake of that device without pointless efforts, reducing air consumption and turbulence.

THAT BI-TURBO SYSTEM improves the hydrodynamic coefficient of penetration [Ch = Rv= Cv.(Re.K/L)], saves energy, increases the velocity and the autonomy. In addition the maneuverability is exceptional.

MANTARAYA Delta Challenger is an adaptation of the original work MANTARAYA, created in 1992. That only symbolic “Art & Technique concept” insures the visibility on the market place and the worldwide protection according to the Berne Convention.

APPLICATIONS: Military & Rescue, operations. Sportive activities and speed records. The rehabilitation of disabled persons. Diving centres, sub aquatic dance, submarine adventure movies.

THE MARKET POTENTIAL can easily reach up to 4000 devices / year.

ENGINEERING: SOLIDWORKS / RHYNO / INVENTOR FUSION
RAPID PROTOTYPING: www.tredim.it

The manufacturing cost is reduced by mean of an overall simpler and more efficient structure: Symmetric shell and independent under-water removable batteries pack.

The shells are moulded in two symmetric parts and assembled by epoxy foam (SICOMIN PB 250 / SD 5604).

The LIPO battery pack is replaceable under-water (Patented concept) and moulded according to the RIM process.
