Hybrid engine for aircraft in works

Boulder County Business Report - By Michael Davidson

The University of Colorado has struck a deal it hopes will bring improved  hybrid engine technology to aircraft, the University of Colorado Technology Transfer Office announced Tuesday.

Tigon EnerTec Inc. is a startup that designs "eco-friendly" propulsion systems. It is working on a system that allows aircraft to use both traditional internal combustion engines and electric motors during flight.

Aircraft operators would have the ability to switch between systems during flight, allowing them to optimize fuel use, Tigon president Jean Koster said.

Gas-powered engines could be used during takeoffs, when aircraft use the most energy, while battery-powered motors could power the aircraft while it is cruising or landing.

The system, nicknamed HELIOS, was developed by a team affiliated with the CU Aerospace Engineering Department. It evolved from a student project, Koster said.

Tigon is working with aerospace and defense contractors to investigate possible applications for unmanned air vehicles. It also is pursuing technology with applications for general aviation and marine and ground transportation.

The company will receive $40,250 from the University's Renewable and Sustainable Energy Institute Market Assessment Program to finance a proof-of-concept project, a statement from the Technology Transfer Office said. 

Tigon is based in Louisville but is planning on moving to Boulder in the next few months, Koster said.
