FIELD: engines and pumps.
SUBSTANCE: heat exchange and noise reduction panel for a gas turbine engine, in particular an aircraft gas turbine engine, comprises outer surface (22), which is intended for air flow blowing and starting from which there are plates (26) in predetermined first and second main directions, wherein cavities (20) form Helmholtz resonators and are connected to first ends (30) of air channels, which second ends are connected to said air flow so that said channels form narrowing of said Helmholtz resonators, passing substantially in first direction, at least one oil chamber (16) located between said outer surface and said at least one cavity and configured to remove thermal energy imparted by oil, wherein said channels are at least partially made in said plates.
EFFECT: proposed improved heat exchange and noise reduction panel for gas turbine engine.
