The main reason that the submerged nozzle clogged during continuous casting of high aluminum low carbon steel is aluminate that aggraded the submerged nozzlewall.
By allowing the influence of ambient pressure to be transmitted to the nozzlewall, the aerospike yields a net thrust advantage over conventional bell-type nozzles.

Thrust vector control is often achieved by throttling individual thrusters or by injecting gas through the nozzlewall to cause a change in the local pressure distribution.
