Embodiment Construction

[0014] The present invention is described in detail below in conjunction with accompanying drawing:

[0015] A dynamic sealing test device for the propulsion section of an aircraft, comprising a box-shaped frame 1, a track 2 is arranged on the bottom surface of the box-shaped frame 1, a mobile trolley 3 is arranged on the track 2, and a top frame of the box-shaped frame 1 An aircraft propulsion section test seal cover 18 is provided, and a lifting platform 9 is provided on the moving trolley 3, and a first bearing inner ring 11 is fixedly arranged on the lifting platform 9. The bearing outer ring 12 is provided with an upper turntable 13, and three hinge seats 14 are arranged on the upper turntable 13. The three hinge seats 14 are arranged at equal intervals on the same circumference. Hinged with oblique support rods 15, the conical aircraft propulsion section 17 is arranged between the three oblique support rods 15, and the upper port of the conical aircraft propulsion sectio...

Abstract

The invention discloses an aircraft thrust section dynamic seal testing device and testing method, and solves the problems of high transportation cost, long consumed time and difficulty in overwater arrangement of measurement and control devices in aircraft thrust section dynamic seal testing. Testing double shafts replace a thrust shaft of an aircraft thrust section, the aircraft thrust section is assembled by a box frame (1), the seal state of the aircraft thrust section is really simulated, the aircraft thrust section (17) with an aircraft thrust section testing seal cover (18) is lifted in a pressure reactor (27) filled with water (28), an internal shaft driving motor (26) and an external shaft driving motor (25) are started after the pressure reactor (27) is sealed, dynamic seal of an internal shaft sealing ring (31) and an external shaft sealing ring (30) is tested, and then seal of a top end static sealing ring (22) of the aircraft thrust section (17) is tested. Assembly automation is high, and time and labor are saved.

Description

technical field [0001] The invention relates to a dynamic seal test device for the propulsion section of an aircraft, in particular to a dynamic seal test device and a test method for truly simulating the operation of the propulsion section of the aircraft in water. Background technique [0002] The power propulsion system is the core component of the underwater vehicle, which determines the product’s range, speed, noise and other performance indicators. The dynamic sealing performance is the basic guarantee for the normal navigation of the underwater vehicle, so the dynamic sealing of the propulsion section of the vehicle is very important. important. The dynamic sealing test of the propulsion section of the aircraft is generally carried out in real time in water. Due to the constraints of the production environment, the test has problems of high transportation cost, long time consumption and difficulty in deploying measurement and control equipment on the water.
