Description
Technical field
The invention belongs to submarine technology field, specially a kind of submarine navigation device is vented experimental provision.
Background technique
When conventional submarine navigates by water under water, since diesel generation power plants must be battery under snorkel state
Charging, a large amount of high-temp waste gas of discharge increase the ocean temperature around submarine.Meanwhile it is largely higher and controllable with temperature
The bubble of gas can also take and roll up seawater and swarm sea so that the infrared thermal characteristics and Sea background of this part seawater generate it is bright
Aobvious infra-red radiation difference.At present many carrier-borne aircrafts, airborne high sensitivity degree infrared detecting set can significantly capture it is red
External radiation difference.Therefore the concealment of submarine substantially reduces, be easily found and attack, so that submarine existence is on the hazard.Therefore,
Influence of the submarine exhaust to its infrared target characteristic is studied, to the investigation of enemy's submarine, detection, strike and improves itself submarine
Stealthy and survival ability be all of great significance.
For the research of submarine wake flow, since the real ship wake flow research under true environment is not only costly but also real
It is big to test difficulty, so submarine wake flow both domestic and external research is more carried out in the indoor large-scale tank of experiment using submarine model.
According to similarity criterion, the submarine model after contracting ratio is carried out to real ship can preferably reflect the feature of true submarine, this is to carry out in fact
Test the theoretical foundation of analog study.External correlative study starting is more early, and two countries, America and Soviet Union just carry out naval vessels wake flow since cold war
A large amount of systematicness experimental work.Either on experiment condition and experimental designs all it is leading compared with China very much.Therefore, it creates
The experimental design of new property is of great significance to the development of the naval vessels wake flow experiment in China.
At present in the related experiment of submarine wake flow, simulation Thermal Wake Detection Technique for Submarines mode mainly outside sink plus hot-air or
Water is that the gas of heating or water are passed through in screw clamp by power source by pipeline with pump, is generated under water with this to simulate submarine
Thermal wake.(the underwater sailing body wake flow water surface is warm in Wu Mengmeng, Chen Baiyi, Zhang Xiufeng, et al. thermal stratification sink for documents
Characterization experiments [J] is infrared and laser engineering, 2011,40 (8)) in such method there are many deficiencies: 1. experimental provisions are more
Complexity, including heating device, pump and associated pipe, if to consider the navigation of the true submarine of the modeling of submarine, pipeline
Design is just increasingly complex.2. part pipeline in the sink, because submerged in water, thermal loss can be very big, outlet oral area is caused
Divide temperature that can be lower than design temperature.3. during exercise, pipeline certainly will follow model to transport to model since submarine model has external pipeline
The dynamic flow field for influencing original submarine wake flow, to influence the case where simulating true submarine movement.
