Datasheet

2021 Nammo Westcott Liquid Engine LEROS4

The Nammo Space designed and manufactured 321 second Isp, MON/ Hydrazine apogee engine delivers a thrust of 1000 N.  The Nammo Space LEROS 4 engine has a thrust range between 900 N and 1100N.  This new development is often referred to as the High Thrust Apogee Engine, or HTAE.  The engine is being prepared for its first in-vacuum hotfire tests in the National Space Propulsion Test Facility at Westcott.

The High Thrust Apogee Engine is been designed as a mission enabling, propellant optimizing engine targeted at ESA deep-space Mars-return missions and has undergone extensive development and hotfire testing.  All Nammo apogee engines are hot-fire tested in the UK National Space Propulsion Test Facility at Nammo Westcott.  High altitude testing and Qualification is targeted for 2021.
