IHI Corporation is proud to announce the successful development and world-first testing of a cutting-edge vacuum pump designed for hybrid laminar flow control (HLFC) systems. The newly developed vacuum pump, equipped with a gas-bearing motor, is a critical component in enabling HLFC systems, which are advanced aerodynamic control technologies with eyes toward reducing aircraft drag in low-pressure air (where air density is about one-tenth of that at ground level).
The Joint Research Center for Electric Architecture contributed to the success of this project by utilizing the evaluation test facilities of the Evaluation Laboratory for Next Generation Motors.
