Intergalactic launches the GS1-EV Eagle5, off-the-shelf thermal management system for eVTOL and electric aircraft

Intergalactic, maker of advanced next-generation thermal management systems, has announced the launch of GS1-EV Eagle5, a new fully integrated thermal management system for cooling the cabin and batteries of eVTOL and other electric aircraft. The company says the Eagle5 is the first off-the-shelf thermal management system designed specifically for the electric aviation industry.

“Thermal management is a critical challenge in getting urban air mobility and regional electric flight off the ground,” said Intergalactic CEO Brian McCann. “Prior to this launch, there wasn’t a standard solution on the market for cooling occupants and the electric batteries on eVTOL and other electric aircraft. We’re thrilled to bring this product to an industry that is ready to fundamentally change how humans travel.”

The company says Eagle5 uses a novel pumped two-phase architecture to deliver highly efficient variable cooling capacity in a lightweight package to regulate the constantly changing temperatures of aircraft electronics, compartments, cabins, and electric batteries. The two technology enablers of the system are a pumped two-phase loop and a thermal capacitor that leverages Intergalactic’s patented microtube heat exchanger technology, unique phase-change thermal materials, and sophisticated systems controls to optimize performance and reliability.

According to the press release “Eagle5 is designed to be highly modular and scalable to allow maximum flexibility in design and application. The published system specifications are designed for a typical eVTOL, and the system can be sized up for larger electric regional aircraft or split into a separate cabin environmental control system (ECS) and battery thermal management system (BTMS). The pumped two-phase architecture can also be modified into a single-phase liquid cooling and heating design.

“To date, most eVTOL airframers have handled all aspects of initial prototyping in house. As the eVTOL and electric aircraft markets mature, airframers will increasingly look to industry partners and suppliers with specialised experience, especially for enabling technologies like thermal management.”
