Founded by three propulsion engineers in 1989, Reaction Engines produces robust technical designs for advanced heat exchangers, air-breathing engines
, and the vehicles they could power.
An ISRO official told Indian news agency IANS that the two air-breathing engines
hugging an Advanced Technology Vehicle rocket normally start breathing air when the rocket reaches a height of 11 kilometres.
The broad objective is to engage engineering students worldwide in practical design activities on air-breathing engines
that are reasonably representative of the real world.
