It is divided into two parts, one fixed, independent of the expert system: the inference engine, and one variable: the knowledge base.

To run an expert system, the engine reasons about the knowledge base like a human.

With logic, the engine is able to generate new information from the knowledge contained in the rule base and data to be processed.

As the rule base is in everyday language ( the engine is untouchable ), expert system can be written much faster than a conventional program, by users or experts, bypassing professional developers and avoiding the need to explain the subject.

Whether the rule base has 10 rules or 10 000, the engine operation is the same.

Historically, the source code for each engine has been released once the code base is 5 years old.

It consisted of a hexagonal base, 1. 04 meters across and 0. 36 meters thick, which contained six magnesium chassis housing the electronics for the science experiments, communications, data encoding, computing, timing, and altitude control, and the power control, battery, and battery charger, as well as the altitude control gas bottles and the rocket engine.

Since the pressure on top of the engine is ambient, this means that base gives no overall thrust ( but it also means that this part of the nozzle doesn't lose thrust by forming a partial vacuum, thus the base part of the nozzle can be ignored at low altitude ).

Further, although the base pressure drops, the recirculation zone keeps the pressure on the base up to a fraction of 1 bar, a pressure that is not balanced by the near vacuum on top of the engine ; this difference in pressure gives extra thrust at altitude, contributing to the altitude compensating effect.
