To increase the performance of the current US satellite launch
capability, new rocket designs must be undertaken. One concept that
has been around since the 50s but yet to be utilized on a launch
platform is the aerospike, or plug nozzle. The aerospike nozzle
concept demonstrates globally better performance compared to a
conventional bell nozzle, since the expansion of the jet is not
bounded by a wall and therefore can adjust to the environment by
changing the outer jet boundary. A dual-expander aerospike nozzle
(DEAN) rocket concept would exceed the Integrated High Payoff
Rocket Propulsion Technology initiative (IHPRPT) phase three goals.
This document covers the design of the chamber and nozzle of the
DEAN. The validation of the design of the DEAN are based on the
model in Numerical Propulsion System Simulation (NPSS TM), added
with the nozzle design from Two-Dimensional Kinematics (TDK 04TM).
The result is a rocket engine that produces 57,231 lbf (254.5 kN)
of thrust at an Isp of 472 s. Additionally, the oxygen wall is made
of silicon carbide, with a melting point of 5580 R (3100 K), and
has a maximum temperature at the throat of 1625 R (902 K).
