Dimensioning of an hydraulic system

for water bombing from an aircraft

Drop pattern

Water dropping is adapted to fire behavior : technologies have to take into account requirements to extinguish efficiently a forest fire.

As a result, the gravitationnal system studied requires to drop constant flow rate which will be linked to height of water on ground. This quantity of water will be determined by analyzing carefully the drop pattern.

This study will deal with the following points :

• Height of drop pattern
• Opening law of doors
• Law for constant flow rate
