Abstract
The utility model relates to a flow guiding windbreak wall for an airplane trial run. The flow guiding windbreak wall for the airplane trial run mainly solves the problem that during the trial run of an engine of an airplane, strong airflow is generated and threatens the safety of surrounding buildings, objects, people and vehicles. The flow guiding windbreak wall for the airplane trial run is characterized in that a single windbreak wall body comprises a main supporting rod (2) and a baffle support (1), wherein the baffle support (1) is in an arc shape, the top of the baffle support (1) is connected with the main supporting rod (2), the bottom of the baffle support (1) is fixed to a foundation bolt (8) through an iron angle (5), a plurality of horizontal flow guiding plates (7) are evenly distributed on the outer surface of the baffle support (1), and the longitudinal section of each flow guiding plate (7) is in an S shape; multiple single windbreak wall bodies are connected through bolts, and the flow guiding plates (7) of the connected multiple single windbreak wall bodies are parallel to one another. The flow guiding windbreak wall for the airplane trial run can reduce the damage of powerful airflow jet from the tail portion to a surrounding area to the maximum extent during the trial run of the engine, and therefore the trial run of the airplane engine is safer.
Description
Technical field
The utility model relates to mechanical field, specifically a kind of aircraft test run water conservancy diversion windbreak for aircraft manufacturing and maintenance.
Background technology
Aircraft engine all needs to carry out engine test completing after manufacture, overhaul and troubleshooting and overall aircraft are repaired, motor complete manufacture and overhaul after monomer test run be all arranged in fixing test bay (test run factory building) and carry out.And motor and overall aircraft interlock test run all the fringe region in apron special-purpose test run level ground is set; aircraft is parked in and on test run level ground, carries out engine test; and aircraft its tail spray when carrying out engine test can produce powerful air-flow, the building of peripheral region, object, personnel and vehicle are caused to grave danger.
Utility model content
The deficiency that the airflow producing when overcoming aircraft engine test run threatens to building, object, personnel and vehicle around, the utility model provides a kind of aircraft test run water conservancy diversion windbreak, the harm that when this aircraft test run water conservancy diversion windbreak can reduce engine test to greatest extent, powerful tail gaseous blast produces peripheral region, makes aircraft engine test run safer.
The technical solution of the utility model is: a kind of aircraft test run water conservancy diversion windbreak, comprise several windbreak monomers, described windbreak monomer comprises main support rod, timbering, described barrier support is curved, barrier support top is connected with main support rod, bottom is fixed on stone bolt by angle steel, and barrier support external surface is evenly equipped with the deflector of some levels, and the vertical section of described deflector is S shape; Several above-mentioned windbreak monomers are bolted, and the deflector of the windbreak monomer after connecting is parallel to each other.
At the bottom of described windbreak monomer, along line and horizontal direction, be 40 °-50 °.
The utlity model has following beneficial effect: owing to taking such scheme, main support rod, support bar support barrier support, form a frame construction, barrier support external surface is fixed with deflector, the air-flow guiding that aircraft engine tail can be ejected is aerial, air-flow is beaten and after plate face, do not produced rightabout active force, avoid ground aircraft safety to produce hidden danger; Meanwhile, deflector is S-shaped, forms several guiding gutters, also can play the effect of decompression and noise abatement.This aircraft test run water conservancy diversion windbreak cost is low, and can move easily and adjust with need of work, so applicable aircraft at present, have dissemination.

1-barrier support in figure, 2-main support rod, 3-pole, 4-cross bar, 5-angle steel, 6-high-strength bolt, 7-deflector, 8-stone bolt, 9-epoxy mortar, 10-set bolt.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By shown in Fig. 1 to Fig. 5, a kind of aircraft test run water conservancy diversion windbreak, by several windbreak monomer compositions, each windbreak monomer also comprises barrier support 1, main support rod 2, and described barrier support 1 is curved, and bottom turns forward, barrier support 1 top is connected with main support rod 2, bottom is connected with angle steel 5 by high-strength bolt 6, and angle steel 5 is fixed on stone bolt 8, and stone bolt 8 use epoxy mortars 9 are fixed on ground.Barrier support 1 external surface is evenly equipped with the deflector 7 of some levels, and the vertical section of described deflector 7 is S shape, and some deflectors 7 are arranged side by side along barrier support 1 external surface, and deflector 7 is fixed on barrier support 1 by set bolt 10.Several above-mentioned windbreak monomers connect successively by bolt, and the deflector 7 of each the windbreak monomer after connecting is parallel to each other, and along line and horizontal direction, are 40 °-50 ° at the bottom of windbreak monomer.
Since the direction that this windbreak is set up should have historical records according to local meteorological department, main flow wind direction considers.During aircraft engine test run, the air-flow of tail spray ejection is fan-shaped diffusing shape, so it highly considers windbreak region is protected building, object, personnel and vehicle behind, and it is high to cover the center of institute's test run aircraft engine; The length of windbreak should be not less than the span width of institute's test run aircraft.When windbreak is used, aircraft adopts tail to enter formula, aircraft should be vertical angle with windbreak, the air intake duct of motor act in accordance with should time wind direction, avoid crosswind (crosswind can make motor occur breathing heavily shake), when aircraft is stopped, the air line distance of its front tread windbreak should be not less than 70m (wherein: A330 series model is not less than 80m), the test run of must not two or more motors simultaneously starting shooting.
Because this windbreak adopts steel structural form, easy for installation, cheap, and can move easily and adjust with need of work, maintenance cost is low; The integrated connection of this windbreak all adopts the securing member of high-strength bolt to connect, and makes whole body of wall produce certain elasticity, compares concrete windbreak and has strengthened application life; And the test run of all aircraft in the applicable current whole world.This windbreak is except becoming requisite safety device when the aircraft engine test run, can also arrange at airfield runway, taxiway edge, play and prevent that in aircraft taxi, tail spray produces harm to peripheral path, farmland, facility (containing: pedestrian, vehicle) etc., have dissemination, particularly possess in recent years very large demand.
