此外,首尾均设有直升机垂直补给平台。 DD963级采用COGAG方式全燃联合使用动力装置。主机为4台LM2500燃气轮机,总功率63.21MW(8600hp),双轴,双舵,2个5叶变距桨。在每轴31.61 MW(43000hp)的输出功率下,螺旋桨的转速为168r/min。
2个主机舱每个长14 m,2个辅机舱在前后主机舱之间,每个长 12.2 m,机舱区域总长52.4m,占舰总长的30.5%。动力装置的比重量为14 kg/kW(10.3 kg/hp)。2个主机舱的总容积(含进、排气道和轮系通道)约4930m3,其比容积为0.0837 m3/kW(O.0615 m3/hp)。
动力装置的油耗(含2台发电机运行时每台 1125 kw的负荷)为443.5 g/kW?h(326g/hp?h)。
动力装置的主要机动性能如下:
LM2500燃气轮机启动(从开始启动至空转)(s)60
LM2500燃气轮机加速(从空转至全功率)(s)30
变距桨改变整个螺距时间(s)30
(1)LM2500燃气轮机主机的主要性能
进气温度(℃)37.8
环境空气压力(MPa)1.01
最大透平转速(r/min)3600
最大油耗(g/kw?h(g/hp?h))259.8(191)
最大制动马力(MW(hp))15.80(21500)
机组大修间隔 约3年
机组外形尺寸(mm)8093×2740×2893
(2)主减速齿轮主要性能
主减速齿轮采用功率分支两级减速结构,其主要性能如下:
输入功率(MW(hp)/分支)15.80MW(21500hp)
输出总功率(MW(h)) 30.65(41700)
轴输入转速(r/min)3600
轴输出转速(r/min)168
齿轮减速比对 21.4/1
最大超载推力(%)150
最大超载扭矩(%)120
齿轮尺寸 左舷(长×宽×高)(mm) 3939×5029×3531
右舷(长×宽×高)(mm)刀87×5029×3531
(3)变距桨主要性能
额定功率(MW(hp)) 29.4(40000))
额定转速(r/min)168
变距桨直径(m)5.18
桨叶数(叶)5
毂径比 0.30
从全速正车至全速倒车的变换时间(s)30
(4)电站
DD963级舰采用 3台 501-K17型燃气轮机发电机组,每台功率为2000 kW,抽气 10%(约 1.36 kg/s),电站的主要特性如下:
额定功率(kw)2000
输出功率特性450V、60Hz、三相
外形尺寸(长×宽×高)(mm) 7422×2130×2443

燃气轮机特性转速(r/min) 13821
功率(MW(hp))2.68(3640)
油耗(g/kw?h)435(无抽气)
(5)废热锅炉
利用电站的每台燃气轮机的废气设三台废热锅炉生产辅助蒸汽,用于“阿斯洛克”发射架的除冰装置、燃油加热器、蒸馏装置、热水加热器、盥洗和厨房等。
(6)动力装置的控制
主推进装置的控制有三个部位。一是机舱中央集控室;二是主机舱设有备用的机旁手动控制台;三是舰桥还设有舰桥控制台。变距浆的螺距和转速是基本的控制参数,控制特性和参数如下:
变距桨转速控制范围(r/min)55~168
变距桨转速控制精度 0级海情时±2r/min
4级海情时±3r/min
变距浆螺距控制范围 -15°~+30°
螺距和转速控制方式 55r/min以上螺距不变,控制转速
55r/min时,转速不变,控制螺距
微调控制量 -5~+20r/min,螺距±5%
电站的控制由中央集控室控制,还设有备用机旁手动控制台。
DD963级舰电力系统的控制特性与参数如下:
并联 平均负载差(%) 5
电压匹配(%) ±2
转速匹配范围(%) 额定转速94~102
最大热态启动时间(S) 45
恢复时间(s) 1.5
