Fire-Buckets VSU-5 and VSU-15

---

This 5-ton fire-container looks like
the inverted parachute and is used
as a water-tank transported by
helicopter to fight a fire.

The filling in any nearest river or lake
takes only several seconds and 1 ton of
water per second scattered over fire
is really effective!

Reefing helps to diminish the tank volume
down to 2.5 ton and use small helicopter
to fight a fire.

The program MONSTR-2.2 helps to
optimize bucket, choose the most suitable
and cheap fabrics and ribbons.

15 ton of water
is loaded in seconds

discharge = 1 ton / s

the capasity can be diminished
down to 8 ton due to reefing
