I'm not sure a five hole nozzle makes it an aerospike
OK, found it floating around the office. It won't be a very _good_ aerospike, with just five nozzle around the circumfrence, but it's an aerospike. They claim a 37% improvement in efficiency. That's not surprising, since Aerotech nozzle are designed to be cheap, not efficient.
ERPS will have to settle for flying the first liquid fuel aerospike.
