Description
Technical field
The invention belongs to field of flight vehicle design, be specifically related to a kind of method of designing of plunderring water surface hedgehopping device.This design utilizes ground effect, water spray vector and hydrofoil untied simulated techniques in the force system in equilibrium of plunderring water surface flying device and controllability design, and look for another way the innovative design found and capture some technical bottleneck of effect aircraft traditionally.
Background technology
At present, ground effect vehicle mainly contains several as follows: hydroairplane, ground effect vehicle, ground effect ship, aerofoil boat etc.
Existing disclosed technical literature " current situation of ground effect vehicle and Research on Its Military Application " (Aeronautics, the first phase in 2006) in have set forth ground effect vehicle be a kind of novel means of delivery utilizing ground effect principle to fly, this article take Russia as main background, describe Development History and the present situation of external, domestic ground effect vehicle, summarize the high performance of ground effect vehicle; Document " ground effect ship aerodynamics simu1ation and Lateral static stability analysis " (unlimited interconnected science and technology, phase March the 6th in 2015) for ground effect ship lateral stability issues, the factors such as flying height, the angle of attack, aspect ratio are analyzed, describes the primary features of ground effect ship; In document " domestic and international ground effect vehicle experimental study " (tactical missile technology, in May, 2010,32-36), collection, arrangement have been carried out to domestic and international ground effect vehicle experimental data, classification, summary are carried out to current experimental technique, has obtained the universal law of ground effect vehicle aerodynamic characteristic.
Before four more than ten years, ground effect vehicle is just considered to the splendid selection of seat transport and operation, and achieves rich experience in development and application, and people are also relatively more deep to its understanding, but the expectation of its propagation and employment situation still apart from people is very far away.For the Russian ground effect vehicle design feature of technological precedence, in order to eliminate the impact of wave effect over the ground to improve flight safety, devise the area stable wing being arranged on tall and big vertical tail top, and this structure makes to break away the safety problem that interference likely causes wing tip structure to touch water becoming fatal; For another example in order to improve ground effect, reduce wing touch water probability, the wide string of small span is adopted to compare wing design, in addition the structure design such as high area stable tailplane put, the weight adding aircraft all in various degree and flight resistance, make its flight efficiency and economy be deteriorated.
But not yet break through because ground effect vehicle still exists many technology barriers so far, the expectation of its application still apart from people is very far away.It is still immature that these technology barriers are mainly reflected in ground effect vehicle design theory, still needs to be broken through in the gordian technique such as road-holding property of overall aerodynamic arrangement, power-boosting, hydrodynamic(al) topological design and ground effect vehicle; In addition, ground effect vehicle also exists a gordian technique difficult problem in structural weight increase, ground effect utilization difficulty, aerodynamic arrangement's limitation etc. effectively could not capture [2], causes ground effect vehicle economy not good enough, is difficult to be applied widely.In a word, described in prosthomere, the technology barrier of ground effect vehicle in overall gas, hydrodynamic(al) layout and aircraft control etc. becomes the bottleneck in its development process.
Meanwhile, Russian ground effect vehicle expert propose the flight path precision and road-holding property, the Italy that utilize fanjet vectored thrust technology to improve aircraft propose utilize hydrofoil technology of soaking provide for underway ground effect vehicle the viewpoints such as stable operating torque with eliminate or reduce the adverse effect of effect.Although it is also before of the remote past that waterjet propulsion technology is suggested, but along with the continuous progress of waterjet propulsor specialized fabrication technology, the preceence of its technology still makes it to become the important research and apply object of ship domain, particularly achieves considerable progress in recent years and applies widely.Before and after 2010, the application of hydraulic efficiency jet propulsion system has been expanded in the appearance of water spray aircraft jetovator especially, also show the advance of waterjet propulsion technology.
The present invention also receives the inspiration of above-mentioned viewpoint just, propose a kind of by water spray vectoring technology, immersion hydrofoil control technology with imitate that airmanship is effectively combined plunder water surface hedgehopping device method of designing.
