trailing_edge_flap_noise(Sf, cf, deltaf, slots, velocity, M, phi, theta, distance, frequency)[source]#

This calculates the noise from the flap trailing edge as a 1/3 octave band sound pressure level.

Assumptions:

Correlation based.

Inputs:

Sf - Flap area [sq.ft] cf - Flap chord [ft] deltaf - Flap deflection [rad] slots - Number of slots (Flap type) velocity - Aircraft speed [kts] M - Mach number [Unitless] phi - Azimuthal angle [rad] theta - Polar angle [rad] distance - Distance from airplane to observer, evaluated at retarded time [ft] frequency - Frequency array [Hz]

Outputs: One Third Octave Band SPL [dB]
