Design and Analysis


Aerojet Rocketdyne’s design engineers develop systems and components for liquid and solid propulsion, composite structures, warheads, and test equipment. The group is responsible for determining the best solution while balancing analytical results, manufacturing capabilities, affordability, and system integration requirements. The Design Department is the primary interface between manufacturing and engineering, and is responsible for the creation of products as well as transferring designs to production. Computer Aided Design tools (Unigraphics and Pro/Engineer) are utilized to create producible designs that exceed our customers’ expectations.

Thermal/Structural Analysis

Aerojet Rocketdyne’s thermal and structural analysts use state-of-the-art analysis tools to tackle the wide variety of thermal and structural design challenges encountered in propulsion systems. System experience includes liquid rocket engines, in-space bipropellant reaction control thrusters, solid rocket boosters, controllable divert and altitude control thrusters, tanks, fluid management systems and electronic circuit boards. Diverse thermal system technical challenges are also analyzed, studied, and solved in a collaborative fashion with other technical disciplines.

Aerojet Rocketdyne’s structural analysis experience is extensive and boasts of trained analysts who have conducted classical and finite element analyses using commercial codes (ANSYS, ABAQUS, and NASTRAN.) Aerojet Rocketdyne’s structural dynamists provide analytical and test support to various Aerojet Rocketdyne product lines. The work performed includes modal surveys, dynamic transients, sine sweeps, random vibration and data reduction / interruption. Depending on complexity, analysis methods involve everything from hand calculations to sophisticated commercial computer codes.

CFD, Combustion and Hypersonic Analysis

Using Linux Clusters and a combination of commercial and in-house codes, Aerojet Rocketdyne provides detailed analysis capabilities that extend to all aspects of our propulsion business. This includes liquid rocket engines, conventional and controllable solid rocket motors and air-breathing propulsion systems. Skilled combustion analysts conduct combustion instability, transient and steady-state performance prediction for liquid rocket engines with years of successful experience. Aerojet Rocketdyne’s hypersonics analysts are responsible for analyzing and helping to design of air-breathing engine components and systems.  Systems applications analyzed consist of ramjets and scramjets, combined-cycle engines, and constant volume combustion systems.


The Ballistics Department uses state-of-the-art methods to design and analyze the igniters and solid propellant grains powering our solid rocket motors (SRMs), and to calculate motor performance under all operating conditions. We work closely with all other aspects of SRM design and analysis to ensure an optimum fit to our customer’s needs.
