Description

A kind of overwater flight aircraft water controller and method thereof

Technical field

The invention belongs to automatic control technology field, particularly relate to a kind of overwater flight aircraft the water surface landing stage water controller and method thereof.

Background technology

Hydroairplane water prior art

The hydroairplane of landing waterborne and the feature of other relevant aircraft as ground effect vehicle (for simplicity, herein hereinafter referred to as " aircraft ") are landed on the water surface.The water surface the subject matter that water day-to-day operation faces and is, water is not static and smooth.

Static and smooth different from land runway, the water surface is not only moving always, and, the surface of water, especially the open waters such as sea, due to impacts such as earth rotation, gravity, bottom topography and circulation, cause the horizontal and vertical of water body self to be moved, water surface image height mountain is the same with valley uneven.In addition, the impact of wind generates the wave of water meter.

The water surface is moving always.The water surface is smooth is dynamic and relative, current maritime affairs hydrograph forecast system lacks for aircraft Exact Forecast the function that water level puts, the diagrammatic forecast in waters in larger time period, in a certain geographic area can only be provided, for the needs of the low speed surface navigations such as boats and ships.Nonetheless, worldwide existing forecasting technique means, meet aircraft water surface landing demand, be namely in time and region two more accurate ripples forecast still very difficult.

Therefore, the essential distinction of operation waterborne and land landing is, one that does not know in advance during water landings fixing airport, does not have the fixing runway that is known in advance, the earth point zone indicating device that ground runway is demarcated more cannot be utilized to complete safety ground.In most of the cases, especially under ocean water surface flight progress, the forecast of accurate water surface situation cannot be carried out in advance.

So to so far, worldwide, during water surface flying, aircraft is when flying to waters, destination, and main dependence aircrew finds the smooth water surface voluntarily, decides water direction in its sole discretion, and most suitable touchdown point, completes water process.

Aircraft in water process, threatens maximum ripples to be gravity waves.According to oceanography definition, mainly the cycle is stormy waves between 4 seconds-30 seconds, surges and coastal wave three kinds gravity wave.

Stormy waves refers to the ripples caused by local wind-force, surging is ripples caused by nonlocal wind-force, the complex that ripples in real world are stormy waves and surge, such as coastal wave is exactly stormy waves and surges in Coastal processes, because the depth of water sharply reduces until the land stopped limits, the kinergety of water collects suddenly, causes the poly-increasing of ripples wave height.Surfing is exactly the billow effect that make use of this coastal wave.

For aircraft for water, the wave height of ripples just threatens a factor of water security, and prior threat is the wavelength of ripples.Under the condition of equal wave height, wavelength is shorter, larger to the threat of aircraft.In order to safety water, first must determine the ripples wavelength in impact area territory, in case overturned by ripples when aircraft water.Secondly, grasp stormy waves and the respective direction of propagation of surging, to select on stormy waves ripples water, or at water of surging on ripples.3rd, finally choose concrete water spot.

Current, the aircraft water surface as above water process, is realized by the artificial judgment of aircrew, personal experience and concrete operations technical ability.Concrete regulation this manual manipulative techniques (hereinafter referred to as FAA-H-8083-23) in the FAA-H-8083-23 " hydroairplane, skid aircraft, float/skid helicopter run book " of Federal Aviation Public Roads Administration, comprise the observational technique of water surface planeness situation and resolution process, course and the concrete skill such as selection of water spot.

Because need aircrew's visual inspection and manual operation, FAA-H-8083-23 emphasizes, for the water surface of status of the water area complexity, the especially vast sea of off-lying sea, in this occasion water very dangerous.

Because need visual inspection to find suitable impact area territory, FAA-H-8083-23 emphasizes, and it is also very dangerous that aircraft water at night.

Above two large danger significantly limit the actual range of use of aircraft and ability of sailing.

Even if daylight time, FAA-H-8083-23 points out, the large or cloud base of water surface fog high very low time, visbility all can be caused not good, the accuracy of directly impact observation; Even if in sunny daytime, due to the sunlight reflecting effect that the water surface is strong, the erroneous judgement of aircrew also can be caused.These restrictions not only increase the difficulty of daily flight, too increase the cost of training aircrew.

But if the aircraft of overwater service is as a kind of transportation means, must possess the service requirement of " round-the-clock ", especially research and development large water aircraft and large-scale ground effect vehicle have been set about by China, meet the need of national Emergency System construction." round-the-clock " of these large-scale aircraft runs, and has been the pre-requisite abilities of contingency tasks.

In sum, in order to make this kind of aircraft have " round-the-clock " service requirement, just must be implemented under various condition outlet capacity, the operational requirements reducing aircrew and training cost.Based on the principles of science, must realize water controling method by automatic technology, design apparatus and system thereof thus, promotes the practicality of this kind of aircraft.

The difficult point of dealing with problems

The earth point area identification of the traffic pattern of airfield, runway course and runway is all at the beginning of the design of airport, the steady state value determined by the data analysis all the year round to local geographic position and environment.When aircrew lands, mission program that announce according to official, that cross through Flight, under the guiding of ground tower man, guided by instrument compressed air (ILS) or the automation of global position system and implement to land, ensure that the aircraft of modern land landing has all-weather capability, made air transportation constantly universal and sustainable development.

But for water landing, still as the aviation starting stage before 100 years, all want aircrew to differentiate voluntarily and temporarily, very original.Newest F AA-H-8083-23 program according to version in 2007: first, in the region that required by task lands, aircrew is flat on 1500 ~ 2000 feet of high-altitudes to fly, and observes the water surface, determines the smooth waters of one's respective area, as the selection in impact area territory.Secondly, be reduced to by aircraft on 500 feet, observe the stormy waves in this waters in detail, surge and coastal wave situation, select water course, such as downsea water, or top ripple water, with the angle in the fluctuation direction of main unrestrained group; 3rd, further falling head, to 100 feet, keeps flat flying, and whether correctly checks above-mentioned observations, determines concrete water spot.Finally, water is implemented.

Must have a kind of failure-free technology solution, facilitate aircrew according to the governing principle of FAA-H-8083-23, select suitable impact area territory according to the planeness of water, this is equivalent to the destination determining land; Afterwards, determine the angled relationships with ripples, namely the course of water, this is equivalent to determine the runway that a certain bar of airfield is concrete; 3rd, according to the wavelength characteristic of ripples, determine suitable a water spot, this is equivalent to set up the landing point on airfield runway.

Summary of the invention

For the problems referred to above, the object of the present invention is to provide a kind of overwater flight aircraft water controller;
