烧的油不一样就又不能比了?这不就好像之前那点排量差么,你在天上遇到油比你好的就要自己撞地球?
按你 ...
我并未说燃料标号不同不能比较,难道你不知道莫林从87到130的型号都有么?
说实在的喷火1用烧87号的莫林真不乍得
At the start of the war the Merlin I, II and III ran on the then standard 87 octane aviation spirit and could supply just over 1,000 horsepower (750 kW) from its 27-litre (1,650- cu in ) displacement: the maximum boost pressure at which the engine could be run using 87 octane fuel was +6 pounds per square inch (141 kPa; 1.44 atm ). [ nb 8 ] However, as early as 1938, at the 16th Paris Air Show, Rolls-Royce displayed two versions of the Merlin rated to use 100 octane fuel.
而当时的DB601也至少是如下状况(B4是87号燃料)
DB601 A-1
Up to 1,100 PS (809 kW) at sea-level with 2,400 rpm, up to 1,020 PS (750 kW) at 2,400 rpm and 4.5 km altitude, B4 fuel
而且当时莫林俯冲和大过载容易熄火,德国空军享受了一段美好时光。
只有你说的多出来的,你以为两级增压传动系统和变速齿轮箱不占重量么。离心机部分你就不用YY了,还有如果你说的废气管道,那还有一个东西集中式排气管。一些非废涡风冷的都装备了。 |
