Our Engineering Services

Engineering

From automobiles to spacecraft, AMA has provided cutting edge solutions in design, modeling, analysis, simulation and optimization. AMA's innovative solutions have helped industry and government improve their product performance.

We specialize in the following areas:

 

Spacecraft and Mission Design

AMA staff are experts in space mission design and analysis. All levels of design are supported,from initial concept definition (where to go and why), to designing mission trajectories (how to get there most efficiently), to sizing and performance analysis of spacecraft systems (what goes there).  We have a focus in spacecraft sizing, system engineering, and space mission design.  AMA personnel are also involved with the design and development of software and tool suites that are used for the sizing and simulation of crewed and robotic spacecraft.  A range of analyses on spacecraft and mission design are performed, from rapid initial mass and power sizing of each spacecraft system to detailed system resource simulation throughout the mission.

Integrated Systems Analysis

AMA specializes in construction of integrated, stochastic analysis for determination of expected return on investment from large, complex systems.  Two recent examples include:

NASA Strategic Analysis Team (Exploration) – provide custom analysis software to NASA for assessment and visualization of logistics delivery to a lunar outpost and the resulting crew functionality and outpost activity. Read more...

Earth Science Campaign Analysis Framework – AMA constructed a full stochastic simulation environment for assessment of implementation options for NASA’s Earth Science Decadal Survey missions. Development and operations cost, launch vehicle reliability predictions, launch manifesting, on-orbit reliability, and end of life disposal are all included. A science value model provides a discriminator between mission implementation approaches. Hide

Flight Mechanics

AMA’s experience in flight mechanics has enabled us to support all aspects of NASA programs.  AMA has helped develop, verify, and utilize separation simulation software based on our expertise in multi-body dynamics.  This has enabled us to be intimately involved in the critical aspects of the stage separation during launches, entry and descent, and launch abort.

Systems Engineering

AMA’s System Engineering team draws on broad expertise and sound judgment to provide superior and in-depth analysis of flight system requirements and project planning.  Our expertise includes:

  • Systems design – design capture,development,requirements flow,integration(interface management,verification/validation) Read More...
  • Project management – earned-value (EVM) metrics and tracking, risk management, resource planning.
  • Documentation – product review (plans, procedures, specs, reports, design studies), technical writing
  • Configuration management – database development and maintenance, data mining and analysis tools
  • Process improvement – Design of Experiments (DOE)Hide

Guidance, Navigation and Controls (GN&C)

From linear estimators to state of the art optimal control schemes, AMA has the experience to delivery efficient Guidance, Navigation, and Control (GN&C) solutions to a broad range of applications.  Our experience in GN&C includes analysis during proposal development, mission planning of actual flight projects, and post flight trajectory reconstruction.

Aerosciences

AMA staff has expertise in computational and experimental aerodynamics, aeroheating, and fluid dynamics from subsonic through hypersonic Mach numbers.  AMA uses higher order CFD codes, including propulsion effects, or engineering methods, as appropriate, to provide pre-flight estimates.  These are integrated with ground-based measurements to develop pre-flight databases for flight simulation and subsequent comparison with flight data.  AMA also provides inputs for flight instrumentation and maneuvers to maximize data quality and usefulness for validation and improvement of pre-flight design tools.
