VTA MicroTurbine

The generator operates at the same speed as the turbine (up to 96,000 rpm) because the permanent magnet is located directly on its drive shaft. The high-frequency alternating current (1,600 Hz) generated in this way is rectified in the turbine''s power electronics and subsequently reversed to alternating current again (50 Hz / 400 V).

MICRO-GENERATOR FOR ULTRA MICRO GAS TURBINE

Keywords: micro turbine, micro generator, permanent magnet INTRODUCTION Due to the increase in micro-power requirements, many efforts have been done over the past decade to build a micro heat engine able to produce electricity. Among those systems, Onera decided to focus on the ultra micro gas turbine concept which seems very promising [1], [2].

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". This paper presents

Experimental Campaign Tests on Ultra Micro Gas

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/m3, lower emissions, less moving elements, multi-fuel

DESIGN AND SIMULATION OF 500 W ULTRA-MICRO GAS TURBINE

This paper presents the development of 500W ultra-micro gas turbine (UMGT) generator. The purpose of the paper is to check the feasibility and develop the prototype of the ultra-micro gas turbine with 500W electrical output. The ultra-micro gas turbine (UMGT) consists of a centrifugal compressor, a radial turbine, an annular combustor, and recuperators, and a high speed

Microturbine

Microturbines have around 15% efficiencies without a recuperator, 20 to 30% with one and they can reach 85% combined thermal-electrical efficiency in cogeneration. [2] The recuperated Niigata Power Systems 300 kW (400 hp) RGT3R thermal efficiency reaches 32.5% while the 360 kW (480 hp) non recuperated RGT3C is at 16.3%. [7] Capstone Turbine claims a 33% LHV

Testing of the Ultra-Micro Gas Turbine Devices (1

One of the types of gas turbines is a micro gas turbine (MGT) with power below 1 MWe [10], and a MGT with power in the range of 1-10 kWe could be called an ultra-micro gas turbine (UMGT) [11]. Air

The Technology Electronic military equipment weight as well as MAV flight time is highly dependent on achievable electric energy density. Therefore, the development of a 300W kerosene-driven Ultra Micro Gas Turbine (UMGT) prototype is proposed, which is foreseen to triple energy density compared to current Li-Ion batteries. UMGT developments of previous

OverviewDesignMarketUltra microAircraftHybrid vehiclesExternal links

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 (
