54mm Aerospike Nozzle Summary

2-piece thermoset molded glass-phenolic "aerospike" nozzle designed to fit AeroTech 54mm RMS reloadable rocket motor hardware for research and experimental purposes. This is the first aerospike nozzle ever to be made available commercially to experimenters.

An aerospike nozzle expands the rocket motor exhaust gases around a center body rather than internally in the exit cone of a conventional nozzle. Aerospike nozzles have the advantage of being self-adjusting to the rocket's ambient pressure in flight and therefore can be more efficient than a traditional fixed-expansion ratio nozzle when used at a wide range of altitudes. In consumer applications however, they are used more for their unique appearance and novelty rather than for practical reasons.

The RCS aerospike nozzle is produced in a set of four parts, a center body and three separate annular rings that provide three "throat diameter" options that are equivalent to a conventional nozzle. The equivalent throat diameters are 0.422", 0.555" and 0.625".

The RCS aerospike nozzle was designed in a partnership with Luke Colby, the designer of the Space Ship Two hybrid rocket motor and founder of Triton Space Technologies. 

Please note that this aerospike nozzle is more sensitive to hot propellants and erosion than conventional nozzles. Experimenters should consider the use of short burn and cooler burning propellant configurations at pressures no greater than 500 PSI. This nozzle is not for all rocket motor applications. We cannot guarantee or warranty that this aerospike nozzle will work with your particular rocket motor design. Depending on your motor design and propellant composition you might see some exhaust impingement and erosion on your aft closure.
