Air Cycle Machine

Air Cycle Machine (DR.18.01)


The requirement pertains to design and development of a 2KW cooling capacity Air Cycle Machine (ACM), which is used in airborne cooling system. The Electronic Warfare (EW) systems are sometimes installed in external pods due to non-availability of internal space in the aircraft. Such pods should have a self-contained liquid cooling system for removing the heat generated in the EW system. Air, cycle Machine is one of the main subsystems of the airborne liquid cooling system. ACM reduces the temperature of the ram air through expansion and supplier the same to an air to liquid heat exchanger for cooling the hot coolant which is circulated through the electronics.

Dear Sir we have gone through the requirements of Air cycle Machine. The conceptual Design carriedout. The critical design challanges are intake and turbomachinary and Embedded syatems for control. We have overcome similar challanges in development of a 20 kgf thrust Jet engine. the Engine designed, manufactured and tested indigenously at our bangalore facility. The Test bed design and commissioning and all associated systems developed in-House. We can come up with a conceptual design and feasible performance, size and approximate weight could be arrived at. is it the right approach. pl offer your valuable comments. with regards Devathathan Mookiaha Poeir Jets Pvt Ltd.
