Jet Engine PBS TJ23U

PBS TJ23U is a small jet engine designed for unmanned systems. 
  • Compact design - accessories including electronics, pump, electric valves, spark plug and engine-mounted sensors
  • Excellent thrust-to-weight ratio, low power consumption in the given power category
  • Electric start, one fuel supply, constant engine thrust independent of ambient temperature
  • Operation via battery connection (3s Li-Po - 2.2 Ah or 4s Li-Fe - 2.5 Ah) and supply of fuel mixture with 3% turbine oil
