HELiFOAM™ Injections System

 

"Pilot Controlled Self-Contained Class A Foam Injections System"

 

HELiFOAM offers the ultimate foam injection systems for Helicopter Monsoon Buckets

 

The HELiFOAM™ system is used by pilots, to transfer and inject Class A foam (fire suppressant) concentrate at 0.5% into each load of water within the monsoon bucket to increase the effectiveness of firebombing drops. The unit is available in the following options:

 

Cabin Option - Designed to be mounted inside the helicopter and allow the operator to store and bulk supply foam concentrate from the original 19 Litre (5 gal) container inside the self-contained spill unit

 

Skid Mount Option – Designed to be mounted on the helicopter skid and allow the operator to store and bulk supply foam concentrate from two (2) original 19 Litre (5 gal) containers inside the cradle

 

 

SYSTEM DESCRIPTION

 

The HELiFOAM™ system is used to create aerated foam which reduces the surface tension of the water, and allows the water to cling to vertical or horizontal surfaces without run off. This allows the water to absorb more heat and provides greater penetration into Class A fuels, which knocks down a fires intensity to allow ground resources access to the fire edge for extinguishment.

 

 

INSTALLATION

 

The pilot or crew member then: (1) affix’s the HELiFOAM unit and its self-contained electrical control system to the helicopter in a way to prevent injury to personnel or damage to the helicopter; (2) inserts a full pail of Class “A” Foam into the unit; (3) places the pick-up wand on the suction side of the pump into the concentrate container and (4) connects the discharge hose extending down the strop into the monsoon bucket using a quick connect coupling.

 

 

POWER TO OPERATE

 

Power source for the dispenser must be obtained from the helicopter by installing a MS 3116F-12-3P, three-pin connector on the cord to the unit. Pin A shall be +28 vdc and pin B for ground

 

 

OPERATION

 

To operate the Self-Contained HELiFOAM unit the Pilot depresses the cyclic mounted dossing button to engage the unit which in turn injects Class “A” Foam directly into the helicopter monsoon bucket after it has been filled with water. 

 

 

DISPENSING

 

Sufficient mixing of the Class “A” Foam concentrate and water will occur from either the drop alone and/or from the flight vibration, if foam is injected into the water inside the helicopter monsoon bucket at least a couple minutes before the drop. More specifically, the drop should be made at 10 to 20 knots airspeed at around 50 feet Above Ground Level (AGL) for optimal mixing.
