The increasing demand for miniaturized radio-controlled vehicles inspired the following research. The uses of these unmanned miniaturized/micro vehicles range from aero-modeling to drones for urban control and military applications too. The common characteristic of these vehicles is the need for a light and compact propulsion system. The radio-controlled

Micro- and Ultra-Micro Gas Turbine (UMGT) devices, based on a micro compressor and a micro turbine installed on the same shaft, are more suitable for this scope for several reasons. They present a higher power density, both in terms of kW/kg and kW/m 3, lower emissions, less moving elements, multi-fuel capability (they operate almost equally

TWO STAGE ULTRA MICRO TURBINE: THERMODYNAMIC AND
Nomadic portable systems, such as micro drones, require a micro power generation system. Among the potential systems, the micro turbine seems interesting. However, at this scale, thermal fluxes involve a decrease in the performance of the turbine. Hence, we study a unique architecture of two stage ultra micro turbine, called "cocoon architecture".

A microturbine (MT) is a small gas turbine with similar cycles and components to a heavy gas turbine. The MT power-to-weight ratio is better than a heavy gas turbine because the reduction of turbine diameters causes an increase in shaft rotational speed. Heavy gas turbine generators are too large and too expensive for distributed power applications, so MTs are developed for small-scale power like electrical power generation alone or as combined cooling, heating, and power (
An experimental study of an ultra-micro scale gas "Turbine"
This study investigated the performance of an ultra-micro scale gas "turbine" over three distinct flow rates of 125, 137.5 and 150 SLPM. Through the measured outputs of inlet static pressure, inlet temperature, outlet temperature, and outlet static pressure, dimensional and non-dimensional performance plots were established.
