DRDO readies on-flight oxygen generator for Tejas​

HAL LCA Tejas Mark I​

The DRDO Monday announced the completion of an indigenous 'on-board oxygen generating system' designed for light combat aircraft (LCA) Tejas, saying it was ready for final trials.

The system - Integrated Life Support System-On Board Oxygen Generating System (ILSS-OBOGS) - will now undergo ground fitment trials on the Tejas, followed by flight trials.

Once trials are successfully completed, India will join the elite club of five countries who have established and mastered the technology in the field of ILSS for military flying.

The system uses the bleed air from the aircraft's engine to produce oxygen, instead of the usual liquid oxygen based system.

The technology consists of OBOGS that provides oxygen for breathing, a breathing regulator that supplies the breathing gas to the aircrew at desired flow and pressure, an Anti-G-Valve (AGV) that inflates the anti-gravity suit to apply desired counter pressure and an Electronic Controller Unit (ECU) to coordinate various functions.

A Defence Research and Development Organisation (DRDO) official said the system will be helpful in long endurance flights.

"This system gets integrated within the confined space available in the aircraft. It replaces the Liquid Oxygen based system (LOX) by utilising bleed air from the aircraft engine by separating oxygen from other components by a process based on Pressure Swing Adsorption (PSA) technology," the official said.

This will prove to be beneficial as the LCA has lesser space to store the liquid oxygen.

"It also provides improved safety, reduced logistics and significantly lowered operational costs," the DRDO official said.

The ILSS-OBOGS has the versatility to be customised to the needs of other fighter aircraft like MIG-29, Sukhoi-30MKI and Mirage-2000.

OBOGS on the LCA is a huge plus, being of indigenous design even better!

 

[Avik274]

good to see.. it's slower but we are doing a good progress.....

 

[sudhir007]

So it may reduce the weight of plane. GOOD JOB DONE BY DRDO

 

[sathya]

does it save any weight ?

how many kgs can be reduced?

Good news but what's up with the 'Elite Club' thing

On-board oxygen gen system of Tejas will be integrated with Su-30MKI

‘On-board oxygen generating system’ (OBOGS) developed by DEBEL, an organ of DRDO was recently handed over to DRDO after completing development work on the system and DEBEL is also has started to work on modified OBOGS to be fitted in another fighter aircrafts used by Indian Air force .

Sukhoi-30MKI, Mirgae-2000 and Mig-29 are aircrafts have been selected which will get crucial ‘integrated life support system’ (ILSS) system like OBOGS Ingeniously developed in India next.

ILSS-OBOGS addresses the need for preventing in-flight hypoxia ( Oxygen deprivation) G-force induced loss of Consciousness during high G manoeuvres.

Older systems used liquid oxygen (LOX) systems which needed to be stored and was seen as dangerous, costly, and inefficient. On-Board Oxygen Generating System (OBOGS) is the newer system, mostly replacing LOX. It taps high-pressure air off the engine(s) and concentrates the oxygen, delivering anywhere between 25-95% oxygen, mixed with clean, outside air (altitude dependent) and is considered safer that the LOX systems in high performance aircraft.

OBOGS offers unlimited endurance, unlike LOX systems which are limited by oxygen storage capability. OBOGS are seen effective and significantly lowers operational costs.

ILSS-OBOGS handed over will be Integrated with Tejas soon and ground trails of system will also start soon and after completing ground trails, flight clearance will be approved after few test.
