Solid Rocket Propulsion – Design Flow

A GenCorp Company
Interactions between components must be accounted for in the design process – usually
by iteration until the design converges
 Grain design affects the internal insulation (flame exposure) and motor case (pressure)
 Nozzle design affects the case (aft opening dia), propellant grain (submergence), and thrust
vector actuation system (gimbaled configuration)
 Attach structures affect the case (skirts, thrust structure) and nozzle (blast tubes, hot-fly out)
 Second-level interactions (ordnance & avionics mounting, etc)

Example – Mars Science Laboratory
A GenCorp Company
 NASA’s Mars Science Laboratory (MSL)
 Aerojet engines assisted with entry, descent,
and landing. Aerojet thrusters also provided
attitude control and trajectory correction
maneuvers during the MSL’s transit to Mars.
 MSL carried eight Aerojet MR-111C 1.0 lbf thrusters, eight Aerojet MR107U 68 lbf thrusters, and eight Aerojet MR-80B 800 lbf thrusters with
a throttleable thrust range of > 100:1.
 68 lbf and 800 lbf thrusters supported the actual landing.

Rocket Propulsion - Summary
A GenCorp Company
 Rocket propulsion is an exciting, challenging, and rewarding
engineering field
 Tough challenges for high energy propellants, high temperature /
lightweight materials, fast acting / high precision control actuation,
and systems integration
 All challenges and tribulations bow-down when your rocket is
developed to perform successfully and reliably
 Rocket propulsion enables some of our most noble endeavors
 Study of our planet – protect our island
 Space exploration – expand human presence to other islands
 Defense of human freedom – protect our way of life now and for
future generations
