FIELD: engines and pumps.
SUBSTANCE: engine housing meant for direction of circular flow comprises the first and second aligned and adjacent shells. First shell comprises cylindrical flange and centring surface while second shell comprises flange and centring means to be radially coupled with centring surface. First shell flange comprises cutouts distributed in its circumference. Note here that said centring holes extend axially from the second shell flange via the cutouts to centring surface when two flanges stay in contact. Another invention of the set relates to axial gas turbine engine comprising the turbofan and turbine. Note here that the flow of streams is defined by above described above.
EFFECT: decreased radius of the engine housing fastening flanges.
