ng experimental data, we determine lining and cell geometry:For the first harmonic, parameters will be:
Distance between linings 28.5 cm;
Lining length 45 cm;
Lining depth 2.5 cm;
Cell length 2 cm
For the second harmonic, parameters will be the following:
Distance between linings 4.5 cm;
Lining length 5 cm;
Lining depth 2.5 cm;
Cell length 0.4 cm.
Figure 7.4 shows the placement of the lining in engine nacelle.
