Airframe noise is addressed by tackling landing gears and high-lift devices, and engine noise through its fan component.
For the past years quieter turbofan engines development accentuated the airframe noise in turn becoming an important noise source in commercial aircrafts.
The physics behind airframe noise generation is still not fully understood and must be characterized before reduction techniques can be implemented.
Also, operators can keep the aircraft in a clean aerodynamic configuration for as long as possible to reduce airframe noise.
flaps and slats have been eliminated-these are a major source of airframe noise when a plane is landing,
The controls were OK, and a cursory look at the instruments and indicators appeared fine, but there was a slight airframe noise.
The goal was to use the code to help predict helicopter airframe noise coming from complex parts, such as landing gear, slats, and flaps.
