Ultra Micro Turbine: The M.I.T Example (論説・解説小特集ガスタービンの極超小型化に向けて)

概要

論文の詳細を見る
The micro turbine concept was launched a few years ago by the M. I. T., regrouping specialists from different fields. It concerns the development of a MEMS based, 1 cm diameter, micro gas tur-bine. Potential applications are devoted to micro drone propulsion, electric power generation for portable power sources in order to replace heavy Lithium batteries, satellites motorization, the surface spread power for boundary layer suction on the plane wings. The manufacturing constraints at such small scales lead to 2D extruded shapes. The Physical constraints stem from viscous effects and from limitations given by 2D geometry. The time scales are generally shorter. Otherwise the material properties are better at such length scales. Transpo-sition from conventional turbomachinery laws is no more effective and new design methods must be applied. The present paper highlights the project progress and the technology breakthrough^<[1][2]>
