Description

Brayton Energy is a developer of turbomachinery systems, specializing in gas turbines, turbojets, turbochargers, and turbo-compounding equipment. In the proposed program, Brayton will design and bench-test the critical elements of novel single-shaft turbocharger with integral motor/alternator capability, including its air bearing system. The proposed variant on turbo-compounding enables motor-assisted"super-charging"for take-off and dash conditions, and electrical power extraction during cruise for auxiliary loads. The very light-weight high-speed alternator will off-set the need for the heavier low-speed alternator and power take-off (PTO) system on the piston engine. A single shaft turbomachine will operate on air bearings. Brayton and the University of Texas Arlington will collaborate on the air bearings, employing the principles of a design which our teams co-developed and tested between 2011 and 2013. In furthering the objectives towards longevity and light-weight, Brayton brings the experience of our silicon nitride radial turbine and volute to the project. This is partially relevant to the very high exhaust temperature of certain rotary engines.
