Abstract
Being
compared with typical destroyer (Type 055, Japan) = USD 60,000,000,00; 13,000
dwt; 112,000 kW; 56 km/h, and with Boeing 787-9 airliner = USD 30,000,000,00;
55 ton payload; 80,000 kW; 900 km/h, my
ship is better than the said destroyer in 30 times by CAPEX and 9 times by OPEX,
and can substitute 8 destroyers. Correspondingly, with the airliner, 200 times
by CAPEX and 80 times by OPEX, substituting 100 them by one ship
Very shorty,
Two key elements of
my ship are
(1) Slightly lower
than sea level, the ship’s nose is tilted back and like a wedge it bends
the upstream water upward in the air, and it substitutes the big water
resistance by the air resistance being in three orders of magnitude less
one Such energy effect is inherent for very big
velocity.. It is new kind of sea ship, breaking all stereotypes.
(2) to add a thin
pressed air cocoon created around a hull of the ship. It reduces the power
loses by the water viscosity practically to zero.
Power consideration
for my ship
W = Q * H = ( l * B
* H / T ) * H = B * H^2 * V = S * H * V
(km/h) / 3.6,
Here: W (kW) –
power; Q (m3/s}- water rate; H (m) – ship’s draft = nose height
submerged; B (m) – ship’s nose beam submerged; S (m2) = B * H; l (m) nose length submerged; V (m/s) – velocity = V
(km/h) / 3.6; T = l / V (m/s)
So
So W = 0.28 * S * H
* V (km/h), hence a power is proportional to a speed !!!.
While for conventional
ships it is W = a * S * V^3 / 2
Let a ship of my
design be
H = 6 m, B = 10 m,
6500 dwt; and V = 900 km/h
Let abovementioned
air cocoon be consuming 10,000 kW
So for the said
ship of my design :
W = 0.28 * 10 * 36 * 900 = 90,700 kW + ~10,000 kW (for the cocoon)
So W ~= 100,000 kW totally
If compared with
the said destroyer:
(6500 /13,000) * (900/56)
= 8. My one instead of the eight by total payload,
and by cost ( 8 *
60 millions) /15 millions = 32 times by
CAPEX,
while 8 * 112,000
/100,000 = 9 times by OPEX
If compared with the said airliner
(5,000/50) * (30,000,000 / 15,000,000) =
200 times cheaper CAPEX,
and (5,000 /50) * 80,000 /100,000) = 80
times less OPEX
So my sea transport can be out of
competition for military quick response.
