俄罗斯利用在叶拉布加工厂制造的喷气式“天竺葵-4”和“天竺葵-5”无人机大幅升级对乌克兰的袭击，部署数量从6月的350架增至8月的2800架。
Russian Jet-Powered Geran Drones Challenge Ukrainian Air Defenses as Deployment Surges Russia has significantly escalated attacks on Ukraine using jet-powered Geran-4 and Geran-5 drones manufactured at its Yelabuga facility, increasing deployment from 350 units in June to 2,800 in August.
这些升级版无人机搭载中国Telefly涡喷发动机，时速约500公里，飞行高度可达7公里，使得常规螺旋桨驱动的拦截机基本失效。
Powered by Chinese Telefly turbojets, the upgraded UAVs reach speeds of approximately 500 km/h and altitudes up to 7 kilometers, rendering conventional propeller-driven interceptors largely ineffective.
单架成本估计为8万美元，这些无人机实施全天候打击，扰乱平民生活并挑战现有防空网络。
With unit costs estimated at $80,000, the drones execute round-the-clock strikes that disrupt civilian life and challenge existing air defense networks.
乌克兰国防开发商正在测试喷气式拦截机原型，但在开发能在极端速度下运行且无需部署成本高昂计算硬件的低成本制导系统方面，面临重大工程和经济障碍。
Ukrainian defense developers are currently testing prototype jet-powered interceptors, but face major engineering and economic hurdles in developing low-cost guidance systems capable of operating at extreme speeds without deploying cost-prohibitive computing hardware.
