我指的是驱逐舰方案
还有侦查巡洋舰的问题,本级舰是我国第一代远洋舰艇,是未来远洋战斗力的基础 ...
驱逐舰方案
1914DD, China DD laid down 1914
Displacement:
1,629 t light; 1,706 t standard; 1,828 t normal; 1,925 t full load
Dimensions: Length (overall / waterline) x beam x draught (normal/deep)
(378.94 ft / 377.30 ft) x 32.81 ft x (11.48 / 11.92 ft)
(115.50 m / 115.00 m) x 10.00 m x (3.50 / 3.63 m)
Armament:
5 - 5.12" / 130 mm 45.0 cal guns - 67.61lbs / 30.67kg shells, 150 per gun
Breech loading guns in deck mounts, 1914 Model
3 x Single mounts on centreline ends, majority aft
2 x Single mounts on sides, forward deck centre
Weight of broadside 338 lbs / 153 kg
8 - 21.0" / 533 mm, 22.97 ft / 7.00 m torpedoes - 1.452 t each, 11.618 t total
In 4 sets of deck mounted reloads
Armour:
- Conning towers: Forward 4.72" / 120 mm, Aft 0.00" / 0 mm
Machinery:
Oil fired boilers, steam turbines,
Direct drive, 2 shafts, 50,300 shp / 37,524 Kw = 35.00 kts
Range 3,000nm at 12.00 kts
Bunker at max displacement = 220 tons
Complement:
139 - 181
Cost:
£0.302 million / $1.207 million
Distribution of weights at normal displacement:
Armament: 63 tons, 3.4%
- Guns: 51 tons, 2.8%
- Torpedoes: 12 tons, 0.6%
Armour: 15 tons, 0.8%
- Conning Tower: 15 tons, 0.8%
Machinery: 1,171 tons, 64.1%
Hull, fittings & equipment: 380 tons, 20.8%
Fuel, ammunition & stores: 198 tons, 10.9%
Miscellaneous weights: 0 tons, 0.0%
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
301 lbs / 136 Kg = 4.5 x 5.1 " / 130 mm shells or 0.2 torpedoes
Stability (Unstable if below 1.00): 1.72
Metacentric height 2.3 ft / 0.7 m
Roll period: 9.1 seconds
Steadiness - As gun platform (Average = 50 %): 34 %
- Recoil effect (Restricted arc if above 1.00): 0.13
Seaboat quality (Average = 1.00): 0.47
Hull form characteristics:
Hull has raised forecastle,
a normal bow and a round stern
Block coefficient (normal/deep): 0.450 / 0.457
Length to Beam Ratio: 11.50 : 1
'Natural speed' for length: 19.42 kts
Power going to wave formation at top speed: 67 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 1.64 ft / 0.50 m
Freeboard (% = length of deck as a percentage of waterline length):
Fore end, Aft end
- Forecastle: 30.00%, 16.73 ft / 5.10 m, 16.73 ft / 5.10 m
- Forward deck: 30.00%, 9.84 ft / 3.00 m, 9.84 ft / 3.00 m
- Aft deck: 25.00%, 9.84 ft / 3.00 m, 9.84 ft / 3.00 m
- Quarter deck: 15.00%, 9.84 ft / 3.00 m, 9.84 ft / 3.00 m
- Average freeboard: 11.91 ft / 3.63 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 215.3%
- Above water (accommodation/working, high = better): 98.1%
Waterplane Area: 7,896 Square feet or 734 Square metres
Displacement factor (Displacement / loading): 45%
Structure weight / hull surface area: 30 lbs/sq ft or 147 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.50
- Longitudinal: 0.81
- Overall: 0.53
Hull space for machinery, storage, compartmentation is extremely poor
Room for accommodation and workspaces is adequate
