摘要

The utility offered by contemporary unmanned aerial vehicles (UAVs) is a step-change from early examples deployed in the 1960s to 1970s, which were used primarily to provide organic over-the-horizon targeting and battle damage assessment (BDA) support to artillery units and naval surface combatants. In contrast, today's UAVs are often highly capable and flexible assets that can perform a range of operations - from intelligence, surveillance, and reconnaissance (ISR) to strike - when configured with the appropriate sensors, mission systems, or weapon payloads. However, while available payloads have evolved and expanded rapidly from basic electro-optical/infrared (EO/IR) sights to encompass advanced mission systems such as electronic warfare (EW) equipment and synthetic aperture radar (SAR), propulsion technology has not typically progressed at a comparable rate. Instead, manufacturers have often been forced to rely on modified legacy aircraft engines that are not optimised for the stresses of extended operations performed by long-endurance UAVs.
