A functional and adaptable Aerospike Nozzle Demonstration. Consists of two units, the Nozzle and the Compressor. Can hook up a computer fan, or similar, to the compressor to push air through the nozzle. Fog/mist can then be used to visualize the flow through the nozzle. Can be used to teach students about flow dynamics on an Aerospike Nozzle as well as spark interest in Rocketry and Aerospace.

The design is parametrically defined. This includes the shape of the nozzle and compressor which are defined by normalized functions ranging from [0, 1]. The following things can be adjusted in the OpenSCAD scripts.
