Sierra Engineering & Software, Inc.

Performs steady-state and transient dynamic analyses for liquid rocket engines to evaluate performance and sequence valves. Modeling capabilities span propulsion systems from small-scale engines to major high-thrust installations.

Develops precise three-dimensional models and engineering drawings for critical propulsion hardware in compliance with industry drafting standards.

• Propulsion Hardware Modeling

  Generates comprehensive three-dimensional models and formal design documentation for thrust chambers, injectors, and specialized igniter hardware using advanced computer-aided design systems.

Predicts structural integrity for challenging thermo-structural problems and models thermal conditions using specialized codes to analyze engine performance, stability, and exhaust plumes.

Conducts grain burnback and ballistics analyses using SPP and TDK software to predict solid and gel propellant performance.

Provides engineering assistance during the planning and execution of propulsion system test operations.

• Test Operations Engineering

  Assists with test plan development, operational sequencing, real-time transient simulation, and post-test data reduction to validate motor performance.
