@isoo if you have time, just read the comments for amusement.
Its the most visible way of telling " i am doing propaganda" .
Their refence job is flying boats, it also uses revolutionary material (wood) and revolutionary structure ( basic as small fisher boats) . Wait a moment,they said composites? I hoped they to use carbon nanotubes ,it would be cost effective.
Yonca-onuk seriously achieved better performance than marc-V but unfortunately their design has some issues to be fixed, no need to detail the problem.
Yet they mention about 110 knots and they have no idea about how its to maneuver at that speed, in 40-50 knots boats use their displacement and sprint to maneuver, and maintaining their momentum by using water splash, but at 110 knot(**1) boats displacement will be small almost zero ( due to close ground effect of air flow ) and it cant use such system . Also in 110 knots ship will be fragile to sea state ,wave height ( cant stand even 10 cm wave ) and the result is failure , for the guys who mention about underwater hydrofoils , do you have any idea how thick hydrofoils should be, so that can stand pressure at 110 knots? Also do you have any idea about hydrofoil sections and their drag/lift ratios?
If they can reach to 110 knots, they have super talents to design structural and material (revolutionary ones
) cant they use the airgap between boat and surface to maintain speed? Sure they cant , such tests can be only one in 2 test labs in world
.
Theoritically their test lab can test such hulls , but they miss a point, even for jamaran they didnt offer a new structure,or a new hullform,they used the existing things by copying ,its a frigate and weight saving is more crucial,they preffered a hull form from 70s and structural designs from 60s ( which from the times that Finite element method wasnt in use that well). So while they cant do it for their frigate, now does iran spend that much effor just for boat?
Lets say this boat is really produced, main reason to have a boat is, its weapon load , it can carry more than planes and has more range, but a boat which hits to 110 knot (ignore the other impossibilities ) will be so small and they are only proud of one machine gun on it? (they cant even put a machine gun,mostly one rider) An aircraft will be much ore efficient than it,so that design is basically useless.
**1 this boat should have a very low displacement for a low drag ,so can be driven with small engines and maintain its speed/weight stability. The other impossibility is the motion stability, and structural strength ,ship cant stand that loads when the motion becomes in stable, reference is, the flipping and broken raceboats.
Ha kimsenin giydiğine kimse karışamaz, benim yorumlamam bu kadar, iyi günler.
