燃气涡轮发动机是航空发动机中绝对的主流，主要包括涡轮喷气发动机、涡轮风扇发动机、涡轮螺旋桨发动机和涡轮轴发动机四种。航空发动机起步于活塞式发动机，发展至今的绝对主流是燃气涡轮发动机。以涡轮喷气发动机为基本构型，针对不同的工作场景，发展演化出总体架构有所差别的涡轮风扇发动机、涡轮螺旋桨发动机和涡轮轴发动机。

3 月挖机销量符合预期，出口销量超预期正增长。根据中国工程机械工业协会的统计，2023 年3 月全国销售各类挖掘机2.56 万台，同比降低31.0%，环比提升19.2%，基本符合CME 此前预期。分市场来看，3 月国内销售13899 台，同比下滑47.7%，降幅再度扩大。我们认为3 月挖机内销增速大幅下滑主要有两方面原因。一方面，去年年底国标切换后，客户对国四新机的接受度仍有待进一步引导；另一方面，部分地区的终端客户回款比例仍然较低，对新机销售造成一定影响。出口方面，3 月挖机出口11679 台，创历史最高值，超出CME此前预期，同比/环比分别增长10.9%/17.3%，出口销量占比45.7%。2023 年1-3 月，全国共销售挖掘机5.75 万台，同比下降25.5%；其中国内销售2.88 万台，同比下降44.4%；出口2.86 万台，同比增长13.3%，出口销量占比49.8%。
