According to the U.S. Air Force Research Laboratory, aircraft were designed for peak power and peak thermal loads and optimized based on mass and volume metrics. Today, three to five times the heat load of legacy aircraft is required; there is limited ability to reject heat to the environment; and there is increasing secondary power demands and system complexity. As a result, research is ongoing for future energy efficiency and optimization approaches to better store, convert, distribute and dissipate energy.
Calnetix Technologies’ core engineering and design team has decades of experience with defense and aerospace applications, having served as a subcontractor to virtually every large prime in the business. Calnetix’s core technology has been enabling many of the permanent magnet motor generator systems in military and commercial aircrafts as well as systems in satellite and space missions, including power thermal management systems, such as air cycle systems (environmental controls) and vapor cycle systems. Calnetix’s products bring many important benefits to aircraft and space applications, including, but not limited to small size, lightweight, high reliability, low maintenance, high power density and high temperature operation.
Calnetix also serves the defense industry as a subcontractor for the motor of the blower system that enables M1 Abrams tanks to deploy smoke screens. The Magnaforce™ high-speed motor is ideal for this application, as it is efficient, reliable, compact, lightweight, and doesn’t generate significant heat inside the tank. Similarly, Calnetix has developed a high efficiency chiller compressor driven by a permanent magnet motor on magnetic bearings via a variable speed drive for Johnson Controls Navy Systems (JCI). Calnetix provided Powerflux™ oil-free magnetic bearings, a Magnaforce™ sensorless high-speed permanent magnet motor, a magnetic bearing controller and a backup bearing system for the new-generation high-efficiency super capacity (HESC) chiller system, consisting of the HESC Chiller and the HESC Variable Speed Drive.
