Based at Toussus-le-Noble within the biggest Paris space, Turbotech is a French firm providing “haute efficiency” propulsion programs for aviation business actors in search of environment friendly and eco-friendly flight options.
Turbotech is the primary firm on the earth to introduce regenerative generators for aeronautical functions, supported by a powerful partnership with the French producer Le Guellec, to develop the important thing know-how of micro-tubes warmth exchangers.
A regenerative turbine is a turbine-engine outfitted with a warmth exchanger, able to recovering the warmth, and reinjecting it in to engine, resulting in a dramatical gasoline burn discount. This warmth is often wasted on typical turbine engines.
The concept of utilizing a warmth exchanger will not be new, it’s used on massive industrial generators, and battle tank generators for instance. However, the true problem within the aviation business is to have a really gentle, compact and dependable warmth exchanger. Turbotech, with the assistance of Le Guellec, has managed to develop an exceptionally performant micro-tube warmth exchanger, due to 10 years of R/D effort.
Turbotech has developed two product traces:
• The TP-R90 turboprop is the right answer to energy uncertified gentle plane or heavy drones. TP-R90 provides a novel flying expertise and can make the dream of each pilot come true: that of flying behind a turbine engine. Using a patented warmth exchanger, the TP-R90 provides a fuel-burn on par with the very best piston engines in the marketplace. A 90kW turboprop utilizing the principal of recovering power contained within the exhaust gases. Light and compact, dependable and vibration free, the TP-R90 provides all the benefits of a gasoline turbine and combines them with a really low gasoline consumption.
• The TG-R55 turbogenerator is the primary onboard electrical geneset devoted to the hybrid-electric plane business. The modern energy plant contains a excessive efficiency turbine fitted with an built-in annular exchanger recovering the power contained within the exhaust gases. A really excessive energy density electrical generator immediately is coupled to the turbine shaft. The highest energy to weight ratio, in comparison with every other electrical energy storage know-how : a 92 kg TG-R55 system carries the identical power as 1000 kg of Lithium-Ion batteries. The energy plant generates electrical energy onboard and paves the best way to hybrid-electric architectures. Used along with batteries, it might probably supply as much as 10 occasions extra vary than a full-electric aircraft.
In April 2018 Safran, by way of its subsidiary Safran Corporate Ventures, and GO CAPITAL introduced that they’re taking a stake within the firm Turbotech.
First TP-R90 turboprop’s needs to be out there in the marketplace in late 2020 or early 2021.
