چکیده

Unmanned aerial vehicles (UAV)s have unique requirements that demand engines with high power-to-weight ratios, fuel efficiency, and reliability. As such, combustion used in UAVs are specialized to meet these requirements. There several types of UAVs, including reciprocating engines, turbine Wankel engines. Recent advancements engine design, such as the use ceramic materials microscale combustion, potential enhance performance durability. This article explores combustion-based particularly microjet an alternative electrically powered unmanned vehicle (UAV) systems. It provides a review recent developments UAV micro combustors, well studies on flame stabilization techniques aimed at enhancing performance. Heat recirculation methods been proposed minimize heat loss combustor walls. has demonstrated employing both bluff-body narrow channels can significantly improve efficiency. The combination observed mesoscale combustors. result, technologies hold great promise for

Micro and Meso Scale Robotic Assembly

Some of the challenges associated with micro systems assembly are examined in this paper, and illustrated with examples of on-going research at the authors’ institution. One of the basic challenges in precision assembly is the need for very high accuracy over a large range of motion. We address this challenge through a “multiscale” approach. This involves the design of assembly tools and proces...
