Strutless diffuser for gas turbine engine

An improved diffuser for a gas turbine engine, said improved diffuser mounted between a compressor section and a burner section of said gas turbine engine, said improved diffuser comprising:

• an inner case wall, said inner case wall being annular shaped and centered about an engine centerline of said gas turbine engine;
• a double outer wall, said double outer wall having a cantilevered case wall and an outer case wall, said cantilevered case wall connected at one end by a connecting wall to said outer case wall, said cantilevered case wall forming an annular flowpath with said inner case wall, said flow path allowing compressed air to flow therethrough from said compressor section to said burner section;
• a plurality of exit guide vanes fixedly attached to said inner case wall and to said cantilevered case wall, said vanes acting as structural support between said cantilevered case wall and said inner case wall, said cantilevered case wall having said vanes mounted proximal to said compressor section and a connecting wall distally located from the said compressor section and unitarily connected to said cantilevered case wall and said outer case wall such that said cantilevered case wall flexes in response to gas pressure and gas temperature, said double outer wall having an annular void formed between said cantilevered case wall and said outer case wall;
• and
• said improved diffuser including a probe mounted in said double outer wall and a seal mounted between said cantilevered case wall and said outer case wall near said vanes for preventing compressor gas leakage from entering said annular void.
