Abstract
The invention provides a testing method for detecting water tightness of a seaplane. Regional water tightness testing devices are arranged on the body of the seaplane, a sealed testing cavity is formed between each water tightness testing device and the surface of the seaplane body, water is injected into each sealed testing cavity, then testing is carried out, and segmented water tightness tests of the seaplane body are realized. In this way, the water buoyancy applied to the body of the seaplane when the seaplane floats on water is simulated, the seaplane body water tightness test is realized, and the water tightness test is completed in a segmented mode, so that the equipment cost and the test risk are lowered, the occupied area is reduced, the implementation is simple and easy, and the method is suitable for popularization and application.
Description
[technical field]
The invention belongs to Aircraft Production technical field of measurement and test, particularly relate to a kind of test method detecting seaplane watertightness.
[background technology]
At present, the domestic watertightness detection to seaplane generally adopts following two kinds of methods: first method pours water in aircraft cabin inside to check the sealing of fuselage, this method will pour into the water of tens of tons in aircraft cabin inside when detecting large aircraft, cannot assess the impact of aircaft configuration, empirical risk is high, and this method and aircraft floating on the water time Impact direction be contrary, testing result is also unreliable.Second method is construction cistern, aircraft is put into pond, the state that simulated aircraft is floating on the water, but existing large aircraft due to size large, want the state that simulated aircraft is floating on the water, need the pond that construction one is suitable with aircraft size, need to take very large-area soil, and drop into huge.
[summary of the invention]
In order to solve the above-mentioned technical matters existed in prior art, the invention provides a kind of can simulated aircraft floating on the water time buoyancy of water suffered by airframe, and adopt Sectional Test form to complete, equipment cost and empirical risk are extremely low, floor area is few, it is simple, easy to implement, and is conducive to the seaplane waterproof test method promoted, apply.
The present invention solves the technical scheme that prior art problem adopts:
A kind of test method detecting seaplane watertightness, by at airframe setting area watertight testing device, make watertight testing device and fuselage surface form sealing test chamber, and toward the water filling of sealing test chamber, test, realize the segmentation waterproof test of airframe.
Further, the upper end in described sealing test chamber is higher than airframe maximum stage line, and the water level in described sealing test chamber is not less than airframe maximum stage line.
Further, the described speed toward the water filling of sealing test chamber is 1m
3/ min, the test duration is 10min.
Further, described watertight testing device is the diaphragm seal or the seal closure that cover fuselage surface, and described diaphragm seal or seal closure are directly pasted onto fuselage surface or are adjacent at fuselage surface by supporting mechanism.
Further, described diaphragm seal is rubber diaphragm, and described seal closure is the metal cap that all lateral margins are provided with O-ring seal.
Further, described diaphragm seal or seal closure can bear pressure >=20kPa.
Further, described supporting mechanism comprises toroidal frame, supporting seat and the support bar of pushing down diaphragm seal or all lateral margins of seal closure, and described support bar adjustable ground is arranged on supporting seat and its end and is connected with toroidal frame.
Beneficial effect of the present invention is as follows:
The present invention is by adopting technique scheme, can simulated aircraft floating on the water time buoyancy of water suffered by airframe, realize fuselage waterproof test, waterproof test adopts segmented version to complete simultaneously, not only greatly reduce equipment cost and empirical risk, also reduce floor area, it is simple, easy to implement, and is conducive to promoting, applying.
[accompanying drawing explanation]
Fig. 1 is a kind of structural representation detecting the test method embodiment of seaplane watertightness of the present invention;
Fig. 2 is a kind of partial structurtes schematic diagram detecting the test method embodiment of seaplane watertightness of the present invention.
[embodiment]
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figures 1 and 2:
Embodiments provide a kind of test method detecting seaplane watertightness, by at airframe 1 setting area watertight testing device 2, watertight testing device 2 is made to form sealing test chamber 3 with fuselage 1 surface, and toward sealing test chamber 3 water filling, test, realize the segmentation waterproof test of airframe.Wherein, the upper end in described sealing test chamber 3 is higher than airframe 1 maximum stage line 4, and the water level in described sealing test chamber 3 is not less than airframe maximum stage line 4, and the speed simultaneously toward sealing test chamber 3 water filling is 1m
3/ min, the test duration is 10min; Described watertight testing device 2 is the diaphragm seal or the seal closure that cover fuselage 1 surface, described diaphragm seal can be rubber diaphragm, described seal closure can be the metal cap that all lateral margins are provided with O-ring seal, and diaphragm seal or seal closure are adjacent on fuselage 1 surface by supporting mechanism 5, and (certainly, described diaphragm seal or seal closure also can directly be pasted onto fuselage 1 on the surface.), and pressure >=20kPa can be born, described supporting mechanism 5 comprises toroidal frame 51, supporting seat 52 and the support bar 53 of pushing down diaphragm seal or all lateral margins of seal closure, and described support bar 53 adjustable ground is arranged on supporting seat 52 and its end and is connected with toroidal frame 51.
Like this, buoyancy of water during by adopting test method simulated aircraft of the present invention floating on the water suffered by airframe, realize fuselage waterproof test, waterproof test adopts segmented version to complete simultaneously, not only greatly reduce equipment cost and empirical risk, also reduce floor area, it is simple, easy to implement, and is conducive to promoting, applying.
Above content is in conjunction with concrete optimal technical scheme further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
