Aerospace

Meggitt provides products for flight test, inertial measurement, and pressure profiling including flutter testing, engine testing and static and dynamic vibration testing.  Our complete range of extreme environment accelerometers, microphones, airborne amplifiers and pressure transducers are used during ground, in-flight and on-board monitoring of aircraft engines.  We play a significant role as new engines are developed, certified and placed into production.

Our design and manufacturing engineers recognize that the world of transducer technology centers around engineering tradeoffs. Generally, the compromises are between the performance characteristics of the transducer and its environmental requirements or the constraints imposed by the phenomenon being measured. For aerospace testing, typical performance requirements are high sensitivity, wide-band frequency response and wide dynamic range. Common environmental problems are high and low temperature extremes, shock, vibration, moisture and thermal transients. Constraints are typically size and weight. Consequently, to meet the unique challenges faced by many of our customers, Meggitt routinely designs custom products using a wide range of technology platforms.
