LEROS 2c Apogee Engine
NASA.
The Nammo Space designed and manufactured 321 second Isp, MON/MMH apogee engine delivers a thrust of 430 N.
The engine has been developed using the advances made Nammo engineers in engine injector/chamber assembly design gained from the ESA High Thrust LEROS 4 Engine program, while maintaining the heritage of our long running production programs. This engine, which utilizes relatively inexpensive Niobium alloys with a Titanium expansion cone. The price of this engine approximately 30% lower than current market offerings for this class of high performance apogee engines.
The Nammo Ireland AEV flow control valves, is being offered to the telecommunications and science mission primes. All Nammo apogee engines are hot-fire tested in the UK National Space Propulsion Test Facility at Nammo Westcott. Delivery timescales are typically 12-18 months.
