Sixty-five percent of the special heat resistant metal in a jet engine is made of cobalt . 喷气发动机中65%的特殊耐热金属材料是用钴制造的。
The jet engine requires a huge scavenging system sometimes using half as much power as the tunnel itself in order to keep contamination low . 喷气发动机试验要求庞大的排气清除系统,以减轻污染,该系统有时要耗去风洞本身功率一半之多。
Jet engines with which most modern high-speed aircrafts are equipped develop thrust on the same principle as the propellers of conventional aero-engines . 大多数现代高速飞机装备的喷气发动机产生推力的原理,与普通航空发动机的螺旋桨相同。
