Hemair develops key cooling system for Indo-Israeli project

HYDERABAD, MARCH 17:
A key cooling system for a large radar system being built under an Indo-Israeli joint venture project has been successfully developed by Hemair Systems India Ltd (HSIL).

The first indigenous cooling system has been custom built for the joint venture — MRSAM (medium range surface to air missile) system — for the Indian Air Force. It ensures the thermal stability of the radar by producing and circulating cool water at 17 degrees C.

The first unit was handed over to Mr S.K. Ray, Director of the RCI, a Defence Research and Development Organisation (DRDO) lab, here today, by Mr Srinivasa Rao, Managing Director of Hemair. The ruggedised version is far cheaper, but matches the quality as tested by the DRDO.

Speaking at the event, Dr V.K. Saraswat, Chief of DRDO and Scientific Adviser to Defence Minister, said, “We needed a cooling system that was effective in Indian conditions. The imported one's were more suitable for European conditions. The decision to build indigenously led to awarding the challenge to Hemair under the joint venture.”

He said the huge projects under the Defence Ministry have opened up many opportunities to Indian industry. The 26 per cent FDI (foreign direct investment) and new policy initiatives have also thrown up possibilities of joint ventures with international companies. The MRSAM is one such example.

Investment

The MRSAM envisages Rs 1,500 crore investment at the development stage and several thousands of crore at the production stage. The first prototype, including the radar, launcher of the missile, should be ready for testing in 2012, he explained.

Describing the cooling system as the “heart of the radar,” Mr Ray said the missile being developed will have a range of 70 km. He pointed out that quality of products was a major concern for the DRDO now, as the defence sector has entered the large scale manufacturing phase. He urged the industry to ponder over ensuring quality.

Mr Srinivasa Rao said, “The product, which costs less than a crore, is not available commercially or manufactured in the organised sector. The company, with a turnover of Rs 65 crore, six operating plans (including one in UK) and 500 employees is expecting multiple orders soon from the project.”

cooling system heart of the radar??
i thought GaAs or GaN chips used in T/R module are heart of an Aesa radar

There are ways to cool the Transmitter...
The F-18 aircraft radar liquid cooling system circulates liquid coolant to remove heat from the radar transmitter high-voltage RF energy modules.


Coolant heated by the transmitter isrouted through a closed loop system to a heatexchanger. The heat exchanger subjects heated coolant to cooling air, and the coolant is returnedby a pump. (A temperature control valve isintegral to the heat exchanger to maintain aminimum coolant temperature level.)

One of three sources of air is induced across the heat exchanger to provide coolant temperature control. During normal flight operations, ram air is induced across the heat exchanger by an electrically powered ramair scoop. At high ram air temperature conditions(hot day—low altitude or high speed—high altitude), the ram air scoop is closed by a signal from the air data computer, and conditioned airfrom the air cycle ACS is delivered to the heat exchanger.

For ground operation, with aircraft weight on wheels, a cooling fan supplies cooling air to the heat exchanger. When cooling air is supplied from the air cycle ACS, a coolant temperature sensor operates through the ACS temperature/flow controller to modulate anairflow valve and limit preconditioned air to theheat exchanger.

The coolant is filtered and the system monitored for filter contamination, ramair door actuator position, low pressure, high temperature, and coolant quantity. A system servicing panel and quick-disconnect fittings are located in the left fuselage. Quick-disconnect fittings are also provided in the coolant lines at the radar transmitter high-voltage module to aid in transmitter replacement by a pre serviced unit.The radar liquid cooling system is made up of a liquid-to-air heat exchanger, a liquid coolant

awesome news BUT can India stop putting garlands on macho looking machines, making them look feminine :D there could be a new aircraft and we dress it up in flowers and make Tom look like Tina. :P ;) . well then again they do refer to aircrafts as " her".

Well this is India..... Adding some desi flavour.....

this is the specialty of indian culture.whenever someone bought a new thing,he first do a "puja" for it's safety.

i think the manufacturer is doing the same..

^yep. Thats our style and culture. I will encourage it. We need to promote our culture and ways right? If we are not following our ways then who
Else will?

+1.

And I really like the way we induct warships breaking a coconut on the hull. :lol:
