Key Intergalactic components upgraded to TRL 8 after passing hundreds of hours of rigorous testing

Battery of tests was designed to simulate an environment more severe than what would be experienced on a supersonic military fighter jet and ensure long-term survival over 20 years of service.  

ST.GEORGE, Utah – August 22, 2022 – Intergalactic, maker of the most advanced next-generation thermal management systems, today announced that seven key components have been upgraded to Technology Readiness Level 8, or TRL 8, after demonstrating robust performance amid a battery of rigorous tests designed to simulate the most demanding aerospace conditions.  

With the TRL 8 designation, these components are now considered “flight qualified.” The military aerospace, civil aviation, and space sectors use the TRL system to evaluate the maturity level of various technologies. The scale goes from one to nine, with higher numbers representing higher maturity and flight-readiness.  

“From our company’s inception, we’ve been determined to develop a new class of thermal management solutions to address the rising heat loads and imperative to reduce size and weight on next-generation aerospace platforms,” says Intergalactic Chief Technology Officer Nick Kaiser. “The challenge, of course, is to prove that new technologies and products can really do the job in the field. With these tests completed, we can confidently say that our thermal management solutions can provide exceptionally strong, reliable performance with margin across all operational conditions.” 

Since its founding in 2016, Intergalactic has tested its components and thermal management systems as part of ongoing internal research and development and in connection with commercial and military program requirements. This particular battery of tests included the Boreas3 Heat Exchanger, HydraX Pump, Carina1 Power Distribution Unit, Fornax Electric Heaters, Aries1 Controller, Libra4 Scroll Compressor, and OrionXD Accumulator.  

The process comprised a dozen tests and hundreds of hours of active testing, including:  

• Endurance vibration exceeding Mil-Std-810G 514.6 Procedure I, with 10 hours per axis, representing two lifetimes of service duty 
• Functional shock exceeding Mil-Std-810G 516.6 Procedure I, with peak force of 27 Gs.  
• Standard shock per Mil-Std-810G 516.8 Procedure II 
• Flight and non-flight temperature per Mil-Std-810G 501.5 and 502.5, with operational temperature from –40 to +71 Celsius and non-operational temperatures from –54 to +71 Celsius 
• Temperature shock per Mil-Std-810G 503.5 Procedure I-C, with temperature ranging from –40 to +71 Celsius, with a 50-degree C minimum 
• Humidity per Mil-Std-810G 507.6 Procedure II 
• Altitude and pressure cycling per Mil-Std-810G 500.5 Procedure II, sea level to 65,000 feet above sea level 
• Rapid decompression per Mil-Std-810G 500.5 Procedure III 
• Explosive environment per Mil-Std-810G 511.5 Procedure I 
• Indirect lightning effect per RTCA DO-160G 22.5.1.2 
• Input power testing per Mil-Std-704E 
• Electrostatic discharge protection per Mil-Std-461G CS118 and IEC 61000 

Intergalactic’s engineers also performed the following test on the Aries1 Controller, Carina1 PDU, and motor controllers for the HydraX Pump and Libra4 Scroll Compressor: 

• Cyclic thermal environment, 500 cycles with temperature ranging from –40 to +71 Celsius at 17 degrees Celsius per minute 

“We baked, shaked, pounded, and zapped these thermal management components and they performed with flying colors,” Kaiser says. “We take pride in the solutions we offer and are thrilled to have the validation of this latest round of tests to show for our team’s tireless efforts to raise the bar in thermal management.”
