正当我国航空发动机(简称航机)更新换代的时候,已有并将有大批航机退役。就目前我国电力十分紧张的情况下,如能发挥退役航机的作用是非常有意义的。 针对航机能源短缺、油耗过高、寿命短和可靠性差等问题,本文提出一种新的航机改造方案。该方案采用煤作燃料,用于发电(暂不考虑热电并用)。热能利用率可达20％以上,即 Just as China’s aeroengine (referred to as aircraft) replacement, there are already and will have a large number of aircraft decommissioned. In the current situation in which electricity in China is very tense, it is of great significance to be able to play the role of decommissioning aircraft. Aiming at the problems of shortage of aircraft energy, high fuel consumption, short service life and poor reliability, this paper proposes a new scheme of aircraft modification. The program uses coal as fuel for power generation (not considering the combined use of thermoelectric). Thermal energy utilization up to 20%, that is
