India’s First Aerospike Engine That Could Lower Cost Of Space Launch Tested By Bengaluru-Based Company

In a first for India, SpaceFields, a Benguluru-based aerospace company, tested an ‘Aerospike’ engine at a testing facility in the Indian Institute of Science Bangalore.

“Multiple cold flow tests were run up to maximum 20 bar chamber pressure,” SpaceFields further said.

Until now all space rocket engines used a bell-shaped nozzle for takeoff. These bell-shaped nozzles work efficiently at lower altitudes, but their efficiency reduces as the rocket goes up in the air due to low pressure at high altitudes.

In simpler terms, a “reduced amount of fuel to bring the same mass to orbit,” tweeted SpaceFields, as compared to the bell-shaped nozzle rocket engine.

These new engines will allow Indian companies to reduce the cost of the launch of the rocket making them more competitive.
