LEROS 1c Apogee Engine

LEROS 1c Apogee Engine

NASA Lucy Mission.

The LEROS 1c is a high performance bipropellant chemical thruster.

The Nammo Space designed and manufactured 324 second Isp, MON/ Hydrazine dual mode apogee engine delivers a thrust of 458N.  This engine has been sold in large numbers (with more than 60 engines delivered) and is the most successful dual mode apogee engine supplied.

The LEROS 1c has been used for both interplanetary and Earth orbit missions. The LEROS 1c is renowned for its reliability and high performance. It is the first choice for satellite primes throughout the world and is very price competitive.  The base material for the thrust chamber and expansion cone is C103 Niobium alloy, coated with R512E Disilicide for oxidation protection.

All Nammo apogee engines are hot-fire tested in the UK National Space Propulsion Test Facility at Nammo Westcott.  Delivery timescales are typically under 12 to 18 months.
