FIELD: test equipment.SUBSTANCE: invention relates to pneumatic tests and can be used in a unit intended for pneumatic tests on a part (2) of a turbo-machine of an aircraft, which includes a gas flow circuit. The essence of the invention: a sealing head (22) includes a sealing element (26) crossed on the inner side with a gas flow passage. With that, the sealing element (26) has a sealing surface (36) intended for being brought into contact with the test part on the level of a hole (40) intended for the supply to it of a gas flow. Besides, the sealing head (22) includes alignment devices (38) of the sealing element (26) relative to the hole (40) of the test part. With that, the alignment devices (38) are rigidly attached to the sealing element (26) and project forwards out of the sealing surface (36) having an external part (44) enveloping these alignment devices.EFFECT: increasing the speed and reliability of test results of a turbo-machine part of an aircraft.12 cl, 8 dwg |
