Interorbital Systems has designed, manufactured,
static-tested (hot-fired), and analyzed the performance of an extensive
series of liquid rocket engines. Through this activity, IOS has developed
the capability of designing and building reliable, high-performance liquid
rocket engines. The company has experience with rocket engines using both
cryogenic and storable propellants (including IOS’ proprietary
hypergolic fuel, Hydrocarbon-X). Recently, IOS has begun testing a new
type of liquid
rocket engine using an expansion-deflection, altitude-compensating nozzle.
This type of nozzle allows a rocket engine to generate the highest
possible specific impulse (a measure of performance) from sea level to
vacuum (space), while at the same time being lighter and smaller in size
than a standard rocket engine. Scaled-up versions of this type of rocket
engine will power both the Sea Star and the Neptune Spaceliner. All of the
rocket engines developed at IOS have the designation “General Purpose
Rocket Engine” (GPRE). Following is a short list of rocket engines
developed and tested at IOS. GPRE
