Modeling Advanced Aircraft Propulsion – MAAP®

Digital Twin, Real Results

Our physics-based MAAP® modeling suite is validated against test data and hardware. It accelerates trades, shrinks prototypes, and saves customers—and our own teams—time and budget from concept through qualification.

  • MAAP® optimizes key design variables and evaluates hundreds of these variables related to system design and performance

  • Combined optimization of power and control systems for fuller system performance

  • Conduct sensitivity analyses on trade studies (“What-if” scenarios)

Why MAAP®?

  • Enables the making of “Big” decisions early, which in aerospace are invariably less expense and avoids downstream delays, many failures and much more expense later in development cycles

  • Evaluate design trades and find optimal solutions for combined vehicle and propulsion optimized together as a system

  • Avoids potential expensive design mistakes with reliable models

  • Design and validation for initial subsystem design choices to within ~15% accuracy

  • Play ‘What if” to conduct sensitivity analyses on trade studies
