The time of our revolutionary project of “flying tractor”'s tests have finally come. And more precisely – the hydrofoil 6-seater cutter "Volga".
Our featurette is that we are the first, who replaced an original engine from
GAZ-53 with a Minsk diesel D-245. Such ones now are setted on everything - on
ZiLs, PAZ bases, Aurora bases, Valdais. And in fact it is tractor turbo-diesel with horsepower of 125. It's more useful to have a diesel than a carburator on
rivers. Before us someone tried to set a diesel, but it was only - Volvo Pentas
and MerCruisers, the costs of which began from є 15k. I.e. much more expensive than a cutter itself, and even used ones for us and
for many others is not available. And this - practically the unique variant
from low-priced diesels. There was a question: will be a cutter that became
heavier on 200 kg, go up on hydrofoils? Protracted calculations with
characteristics of engine, wings and propellers talked that she will go up.
Remained to check it in practice. And annual job performance now is on the
water.
The tests passed successfully.
Cutter shown an excellent dynamics. An acceleration was limited not so much
engine performance, but by durability of the propeller shaft .
A cutter has shown expected speed at 65 km/h. At a further acceleration there
was some instability of motion on hydrofoils - it's a cause for future research
work.
