A truncated plug nozzle would qualify as an aerospike engine, but I gather the one in question was more a big engine with 5 nozzles than a true aerospike (or plug nozzle for that matter).
The engine was an Aerotech L series; only the nozzle was different. It was nice little stainless steel cone - not truncated - with 5 nozzles around the perimeter. So what I'm hearing is that while this is a plug nozzle, and even a spike, it isn't an aerospike. Yes?
Yes. A plug nozzle and an aerospike are two variations on a single concept, and should have similar performance characteristics. The aerospike will, of course, be lighter.
