Modeling and Simulation

Andrews specializes in the modeling and simulation of a broad range of aerospace systems.  Specific capabilities include:

Subsystem performance modeling: Use of MATLAB and Simulink to evaluate the performance of a range of systems, including propulsion system, complex crogenic / thermodynamic cycles, and system architectures (e.g. Lunar logistics architecture)

System weights analysis: Andrews has developed several in-house tools for preliminary and detailed weights analysis.  These systems have been used during the conceptual design of launch vehicles and on details production programs, including the Ares I Launch Vehicle

Trajectory Analysis: Andrews uses OTIS and POST trajectory optimization programs for 3DOF and 6DOF vehicle performance assessments 

6DOF Analysis: Andrews uses standard control algorithms to assess system performance and derive control surface / thruster sizes and performance characteristics.
