摘要

Unmanned Vehicles (UVs) that are small enough for a man to carry provide one of the more promising technologies for obtaining live situation intelligence. However, UVs developed for applications, including air (UAV), ground (UGV) or underwater (UUV), with gas or diesel engines may not be practical because of their noise, weight and other application-specific issues. Patented high-efficiency brushless ring motor technology developed by ThinGap Corporation of Ventura, CA promises to reduce energy consumption, allowing UAVs plenty of flight time once airborne. For UGVs and UUVs, the ring motor can eliminate transmissions, allowing larger payloads, and the ability to move faster, farther or longer between battery charges. The noise generated by gas or diesel engine UVs deployed for surveillance, sensing and swarming is enough to forewarn the enemy, making the UV an easy target. As a result, information and any element of surprise are lost. The problems extend beyond the noise, which sounds much like a RC-controlled airplane, to include vibration that impairs imaging capabilities and a heat signature that can be picked up by night vision devices.
