Abstract
Disclosed is a high-speed amphibious vehicle. In order to reduce water resistance and realize high-speed water sailing, firstly, a retractable sharp head is arranged on a vehicle head, side plates arranged on left and right sides of the vehicle head are combined in a holding manner so as to form the sharp head, and secondly, a retractable side water flange is additionally arranged at the bottom of the vehicle head, a retractable tail water flange is disposed on a vehicle tail so as to increase movable buoyancy of the vehicle, draft of water is reduced, and accordingly the high-speed water sailing can be realized indirectly. The sharp head and the side water flange are connected onto a hydraulic motor or control motor and are simultaneously driven to rotate. Compared with an existing amphibious vehicle, the high-speed amphibious vehicle is higher in speed when sailing in water, and land running property of the high-speed amphibious vehicle is not affected.
Description
Technical field
The utility model relates to land and water driving skills art, particularly a kind of high speed amph.
Background technology
The wave that produces during existing land and water car water sailing is very big, speed is low, and performance need improve.Water was to the resistance of car when the principal element that influences route speed was its angle of rake thrust and water sailing, and the latter is a most important reason.Want that the speed increment that obtains by improvement propelling unit increase thrust is extremely limited, then lose more than gain by strengthening angle of rake horsepower input, a bit run into the wave that bigger water resistance (water resistance and the speed of a motor vehicle square be directly proportional) and generation aggravate resistance because most of energy is used in to overcome because of speed improves.
The composition of land and water car water sailing resistance: the so-called wave making resistance that water produces to the friction drag that immerses car body surface wherein, form resistance, by the gravity of water.The statistical information that the navigation total drag is formed shows: friction drag accounts for 5%～10%, and form resistance accounts for 70%～80%, and wave making resistance accounts for 15%～20%, and obviously, the form resistance accounting is heavy maximum.These three kinds of resistances are all relevant with the shape of car.
The wide ratio of land and water vehicle commander is little, helps landly travelling and turning to.Existing land and water car, what have is provided with front slide and washboard, tail water wing plate, during water sailing, can produce lift and make car body 1 come-up to reduce water resistance.As the tail water wing plate 3 of Fig. 1, tail water wing plate 3 usefulness hydraulic actuating cylinders 2 are got in touch with the afterbody of car body 1, and during water sailing, modulated pressure cylinder 2 is opened tail water wing plate 3 state as shown in Figure 1, and the cross section of tail water wing plate 3 is the aircraft wing shape.Front slide and washboard do not draw in the drawings.But during water sailing, front slide, washboard, tail water wing plate also produce some resistances, and washboard then produces bigger resistance.
The car body drinking water is shallow more, and propelling unit is easy more air-breathing.When slide plate makes the moving buoyancy come-up of car acquisition reduce draft, may strengthen angle of rake gettering effect, cause propulsive force to reduce.
Studies show that, the high speed amph navigates by water in water and is divided into three phases: F/s is a hull borne, speed is less than 15 kilometers/h, quiet buoyancy maximum, and moving buoyancy is very little, the gross buoyancy that vehicle is subjected to is little, mainly float by quiet buoyancy, so draft is the darkest, but speed is low, thereby water resistance is less.Subordinate phase is the transition operational configuration, and about the about 25 kilometers/h of car speed, the quiet buoyancy of vehicle is less, and moving buoyancy is bigger, and the gross buoyancy that vehicle is subjected to is little bigger than F/s, and draft is not dark, but because speed increases, water resistance is very big.Phase III is a sliding state, car speed about 35 kilometers/more than the h, the quiet buoyancy minimum of vehicle, and moving buoyancy maximum, the little ratio of the gross buoyancy that vehicle is subjected to first rank, second section are all many greatly, and the vehicle draft is very shallow, as the almost planking of ship quilt, water resistance declines to a great extent, the resistance minimum.
It seems, the land and water car will be implemented in the water high speed and travel (40 kilometers/more than the h), must pass through the transition operational configuration of subordinate phase through the hull borne of F/s thereupon, the moving buoyancy of lifting arrives to a certain degree gradually, thereby reaches the sliding state of phase III.But the water resistance peak value that (about about 25 kilometers/h) can occur going beyond under the transition operational configuration.Do not change the vehicle physique structure and depend merely on and improve power system and can't allow vehicle enter sliding state.
In order to improve existing land and water car water sailing speed (reaching per hour more than 40 kilometers) to strengthen its hydrodynamic performance, must the comprehensive research drag reduction and reduce angle of rake gettering effect technology, to in the research drag reduction technology, must take into account and reduce air-breathing technical study in other words.Know that by above-mentioned analysis the vehicle when optimizing operating mode waterborne is linear, increase hydrofoil may be best solution.
