Pulsar Space today announced the successful completion of a 36-second integrated static fire of its Vortex engine at Pulsar Launch Complex-1 (PLC-1), Astraea Range. The test achieved a peak thrust of 1,127 kN, validating the engine’s performance and readiness for upcoming orbital launch operations.
The static fire tested full-duration combustion, turbopump performance, propellant feed systems, and nozzle thermal characteristics. All primary parameters remained within nominal limits, confirming the stability of the engine’s LOX/methane design and propulsion systems.
Key test highlights include:
Burn duration: 36 seconds
Peak thrust: 1,127 kN
Chamber pressure: ~12 MPa, stable
LOX temperature / pressure: −183 °C / 8.6–8.9 MPa
Methane temperature / pressure: −158 °C / 7.9–8.2 MPa
Nozzle wall temperature: 780–820 °C
Pulsar-1 is Pulsar Space’s inaugural orbital-class launch vehicle, designed to deliver payloads to Low Earth Orbit (LEO) with high reliability and efficiency. The company is on track for its first orbital demonstration flight in Q1 2026.
