Engine packing box changes testbed frame and has suitable portable and reasonable reliable pneumatics, structural design, and it is huge to have solved conventional testbed area, immovable drawback, and the motor -driven cross -country ability of taking a trial run for the engine outfield can provide the possibility.
Description
Technical field
This utility model relates to a kind of engine testsand, particularly to a kind of test bay utilizing engine packing box to reequip.
Background technology
Aero Engine Testing plays indispensable effect in Aero-engine Development, the reasonability that electromotor designs can be verified by Aero Engine Testing, the improvement designed for electromotor and perfect offer data support, the reliability of electromotor can be tested, probe into new technique and the new direction of electromotor design, for the offer foundation that advances of engine technology.
Conventional Aero-engine testing platform structure is complicated, floor space is wide, generally it is made up of multiple subsystems such as air inlet system and exhaust system, equipment body system, TT&C system, oil piping system and supervision systems, it is possible to realize in Aero Engine Testing process the monitoring of performance parameter in all directions under different conditions, on different cross section. Can be from another point of view, owing to Aero Engine Testing device structure is complicated, subsystem is numerous, the Aero Engine Testing equipment making routine does not have mobility, taking a flight test in electromotor outfield needs to carry out engine test, then needing that electromotor is transported back proving ground to carry out, thus creating substantial amounts of human and material resources and temporal waste, govern advancing of engine technology to a certain extent. From domestic at present, existing mobile Aero Engine Testing equipment is still relatively bulky, it is impossible to meet the requirement to establishment and motor-driven cross-country ability in user's use procedure.
Summary of the invention
The purpose of the present invention: the engine testsand that a kind of cost is low, disclosure satisfy that maneuverability requirement is provided.
Technical scheme: a kind of engine testsand, it is characterized by: described test bay includes engine packing box 1 and air inlet combination unit 2, air inlet combination unit 2 is arranged on engine packing box 1 base plate, air inlet combination unit 2 includes flowtube 3 and support 4, and flowtube 3 is arranged on support 4.
As a kind of improvement of the technical program, flowtube 3 is arranged on support 4 by journal stirrup 7, support 4 is provided with fixed block 5, fixed block 5 has groove, and journal stirrup is arranged in groove, and groove is axially installed with bolt 6 along groove.
Beneficial effects of the present invention: compared with conventional test bay, engine packing box changes test bay and has the advantage that and effect:
A) portability. Reequiping complete engine packing box and change its Test Rig greatest length less than 2000mm, Breadth Maximum is less than 600mm, and maximum height is less than 700mm, and overall weight is less than 250kg, it is possible to meet the movement requirement under the various condition of aeroamphibious.
B) pneumatic design is reasonable. After packing crates changes its Test Rig design, by ANSYS12, engine intake flow field is analyzed, it has been found that tend towards stability substantially in inlet velocity field, relatively uniform; Measure cross section wall static pressure and center differing pressure is very few, fully meet the electromotor overall test requirement to inlet air conditions.
C) structural design is reliable. Engine packing box changes major part spare part in its Test Rig and all adopts stainless steel material, it is welded by oxy-arc, flowtube assembly is connected with connecting plate with engine packing box bolt, shown by test of many times, this modification scheme sound construction, connect reliable, fully meet conventional engine test requirements document.
In sum, engine packing box changes its Test Rig and has suitable portability and reasonable pneumatic, structural design reliably, solving conventional test bay floor space huge, immovable drawback, the motor-driven cross-country ability for the test run of electromotor outfield provides probability.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical program is described in further detail.
As shown in Figures 1 to 3, a kind of engine testsand, is characterized by: described test bay includes engine packing box 1 and air inlet combination unit 2, air inlet combination unit 2 is arranged on engine packing box 1 base plate, air inlet combination unit 2 includes flowtube 3 and support 4, and flowtube 3 is arranged on support 4.
This engine testsand (see Fig. 1) is to convert on the basis of the existing packing crates 1 of electromotor, the engine test requirement to inlet air conditions is realized by increasing air inlet combination unit 2 at engine charge leading portion, isolation large granular impurity can be realized, ensure the requirement of flow field quality. Simplify control system, adopt the ground detector developed to complete the adjustment of each state of engine test. Simplify test system, by measure the temperature of import and export, pressure, convert inlet flow rate, calculate motor power, examining instrument monitoring parameter in combination, such that it is able to obtain electromotor check test about total Test information. Wherein main transformation part is air inlet combination unit 2, and it is mainly made up of flowtube 3 and support 4 two large divisions.
Flowtube 3 is installed on engine intake, is used for measuring engine intake air mass flow, water conservancy diversion basin, flow measuring section, journal stirrup 7 etc. are welded.
Flowtube 3 and engine intake adopt O to seal, and O is arranged in the groove at measuring section rear, apply pretightning force to journal stirrup 7 by the bolt 6 on fixed block 5 on support 4 and flowtube 3 are pressed on engine charge casing.
Flowtube water conservancy diversion basin profile is twisted-pair cable, and uniform four the wall static pressure holes of circumference on measuring section, static pressure pressure guiding pipe isStainless steel tube, static pressure measurement cross section is from water conservancy diversion basin trailing edge distance L1=0.24D, from outlet distance L2=1.55D.
Support 4 is welded by Air Filter, channel-section steel, bearing, pole, fixed block 5, realizes the connection with engine packing box by connecting plate and bolt, and flowtube height can be completed by the mode of shimming below pole.
Support leading portion sets Air Filter, and overall dimensions is 500 �� 550 �� 200, and at angle bar frame interior welds 15 order metal gauze, its flow rate is 57.3%, and circulation area is 157575mm2��
