摘　　要：介绍了燃气轮机的技术特点及其在汽车动力领域的应用与发展。为进一步提升燃气轮机的效率,可采用回热器,并进一步提高涡轮前的燃气温度,同时可重点发展采用陶瓷部件的燃气轮机。据此,重点介绍了车用陶瓷燃气轮机及其发展现状。最后,将燃气轮机与柴油机这类传统内燃机进行对比研究。与柴油机相比,燃气轮机没有往复运动件,且转速较高,因此可以大幅减小机组的比重量和外形尺寸。考虑到结构紧凑性及总重量等方面的优势,目前燃气轮机已在坦克等装甲车辆中得到应用。通过相关研究,也已证明将燃气轮机用于车辆动力来源也有一定的技术可行性。除了军用车辆之外,目前有望将燃气轮机发展为重型汽车的动力装置。The technical characteristics of gas turbine and its application and development in automotive power field are introduced.In order to further improve the efficiency of the gas turbine,the regenerator can be used,and the gas temperature in front of the turbine can be further improved.At the same time,the gas turbine with ceramic parts can be developed with emphasis.On this basis,the ceramic gas turbine for vehicles and its development status are mainly introduced.Finally,a comparative study of traditional internal combustion engines such as gas turbines and diesel engines is carried out.Compared with diesel engine,gas turbine has no reciprocating parts,and its speed is high,so the specific weight and overall dimensions of the unit can be greatly reduced.Considering the advantages of compact structure and total weight,gas turbines have been used in armored vehicles such as tanks.Through relevant research,it has also been proved that it is technically feasible to use gas turbines as vehicle power sources.In addition to military vehicles,gas turbines are now expected to be developed as power plants for heavy vehicles.
