Compact Bidirectional Acoustic Airflow Meter (CBAAM)


C.B.A.A.M. is a device that measures the gas velocity and speed of sound across the air stream.

Technology Readiness Level: Prototype


  • For use by operators of turbine-powered aircraft/rotorcraft fleet
  • Gas turbine OEMs (Original Equipment Manufacturers)
  • Maintenance Managers/Public Housing Manager specialists
  • HVAC system providers


  • Real-time measurement allows for integration with engine controls, meaning increased aircraft performance and uptime
  • Accurate measurement improves available engine power by as much as 5% by eliminating conservative derating.
  • Enables more precise control of power-critical flight systems
  • Energy conservation: reduction of fuel consumption of rotorcraft fleet over entire operating life
