Alternative propellants for Isp up to 230-240 s are possible (not yet tested).

The motor is re-usable

The motor can be manufactured in different lengths, for burn times other than described above.

A performance certificate issued by ELMEC, Ploiesti, Romania, is available.

SRM-30 rocket motor

  • Thrust: 340 Newtons
  • Burn time: 0.755 seconds
  • Operating pressure: 62 bar
  • Thrust profile: neutral (within 9-10%)
  • Manufacturing materials: Al casing, steel nozzle/bulkhead
  • Ignition: electric, 2 Amps at 12 Volts
  • FLIGHT TESTED

 

N.B. The performance relates to a low-cost propellant, of Isp ~ 150 seconds. We can easily substitute this for higher-performance propellants, for extended thrust duration.
