Patent number: 10308365Abstract: Disclosed is a high-power electric motor and its fabrication technology. The motor and its distributed power electronics are all being fully integrated in a conventional turbofan engine. The rotor drives directly (with no gears) the LP shaft of the jet engine while requiring minimal modification to a basic jet engine and without distortion to the nacelle geometry. In principle such a configuration should be suitable for a power level of 10 to 50 MW, which makes it fully capable of providing a standard flight envelope by only using electric energy.Type: GrantFiled: October 12, 2016Date of Patent: June 4, 2019Assignee: Codrin-Gruie (CG) CantemirInventor: Codrin-Gruie Cantemir

Patent number: 9803802Abstract: A method of compressing gas includes maintaining a volume of gas at a first pressure within a first chamber. Pressurized liquid is forced into the first chamber through a nozzle having a curved profile. Based on the Coanda effect, the liquid compresses the volume of gas to a second pressure greater than the first pressure. The liquid is separated from the gas in a second chamber while maintaining the gas at the second pressure to provide compressed, dry gas.Type: GrantFiled: May 22, 2013Date of Patent: October 31, 2017Assignee: Ohio State Innnovation FoundationInventors: Codrin-Gruie Cantemir, Fabio Chiara, Marcello Canova, James Durand

Patent number: 9540936Abstract: A method and at least two devices demonstrate improvements to energy extraction from a compressible working fluid in a liquid ring heat engine, which has a rotor mounted in a case. A space in the case is occupied by a liquid that establishes a liquid ring piston for the rotor. The rotor defines at least a first and a second operating zone. In the first zone, the working fluid is expanded against the liquid and, in the second zone, the working fluid is re-compressed. Between the two zones, the working fluid is cooled. In one device, the cooling step occurs on the rotor in a third zone. In another device, the cooling occurs outside of the case.Type: GrantFiled: November 23, 2011Date of Patent: January 10, 2017Assignee: Ohio State Innovation FoundationInventors: Codrin-Gruie Cantemir, Fabio Chiara, Marcello Canova

Publication number: 20160097381Abstract: A method of compressing a gas includes maintaining a first volume of liquid in a first high pressure chamber and maintaining a first volume of gas in a second high pressure chamber, wherein the first volume of gas is at a first pressure and the first high pressure chamber and the second high pressure chamber are fluidly connected through a high pressure pump. A pressurized gas is forced into the first high pressure chamber having the first volume of liquid and simultaneously pumping, using the high pressure pump, at least a portion of the first volume of liquid in the first high pressure chamber to the second high pressure chamber, wherein the first volume of liquid pumped into the second high pressure chamber compresses the first volume of gas in the second high pressure chamber to a second pressure greater than the first pressure.Type: ApplicationFiled: October 2, 2014Publication date: April 7, 2016Inventors: Fabio Chiara, Codrin-Gruie Cantemir, Marcello Canova, James Durand
