AEROSPIKE ENGINES

POLARIS develops a series of linear aerospike rocket engines to power our spaceplanes as well as scaled demonstrators. Aerospike engines promise significant efficiency increases compared to conventional rocket engines. Moreover, the LOX/kerosene linear aerospike engines under development at POLARIS enable a very efficient engine/airframe integration for the flat-shaped flying wing configuration of our spaceplanes.

On October 29th, 2024, our latest flight demonstrator MIRA II wrote aerospace history with the first-ever in-flight ignition of a linear aerospike rocket engine. Check here for more information.

Parts of our aerospike activities are conducted under Bundeswehr (German Armed Forces) study contracts.
