Engines

Three generations of student-built engines, all burning ethanol with nitrous oxide.

NarlikarFoundation

Our foundational engine

The engine every later one grew from. It burns ethanol with nitrous oxide and was the first liquid engine we fired.

1.5 kNPeak thrust6 s burn time

Highlights

  1. Our foundational engine.
  2. Ethanol and nitrous oxide powered.
  3. A 6 second burn at 1.5 kN peak thrust.

Flown on Vikrant

Named after the Pune scientist behind CFD and the SIMPLE algorithm. It powers Vikrant, India's first student-built liquid engine rocket.

2.2 kNPeak thrustL class · 4,500 Ns

Highlights

  1. Named after the Pune scientist behind CFD and the SIMPLE algorithm.
  2. An internal downcomer based system for fuel transfer.
  3. Our own SRAD weight based quick disconnect system.
  4. Flew on Vikrant.
