Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
The invention provides a kind of novel jet engine, its side view, plan view, flux map and front elevation are respectively as Figure 1-Figure 4, wherein in Fig. 4 for the ease of display, make front elevation respectively according to 7 stages such as A-G, below each part in A-G etc. 7 sections be described.
A section: A section mainly provides the entrance of air, wherein, is also equipped with the front step bearing 105 of gas compressor hollow spindle, and the forward thrust of carrying air breathing engine is also the pipeline that air-flow in hollow spindle (mainly nitrogen) removes N duct 100 current path.Due to the end outlet place of N duct, in the periphery being enclosed in rectangular nozzle, when aircraft high-speed flight, the oncoming high velocity air of motor head is relative to the near vacuum at the end outlet place of N duct 100, produce very large pressure reduction, cause the rotation function of the B section compressor work flabellum when aircraft high-speed flight also not merely to rely on the electric energy of variable-frequency motor, and mainly rely on the energy of speed punching press.
B section: the power section of the variable-frequency motor of gas compressor, outermost is the N duct 100 closed outer ring border, there are 48 slot for windings inside, outside, hollow spindle is provided with dynamic flabellum, form the rotor of variable-frequency motor, the edge of dynamic flabellum is porose, through the eddy current conduction band (anti-torque thrust that carrying rotating magnetic field produces) being parallel to main-shaft axis, can also have the bolt of locking eddy current conduction band.The eddy current conduction band perpendicular to hollow spindle axis is embedded with in two flabellums that power on hollow spindle moves both sides before and after flabellum.Power moves flabellum and main shaft not to be affected the magnetic line of force and passes, and its material adopted is necessary for the polymer (such as high strength plastic materials) not producing eddy current.Because exchanging the rotating magnetic field that winding produces, the eddy current conduction band of a square shaped frame-shaped produces thrust, and can not produce hot eddy current in other place, therefore can increase substantially the mechanical efficiency that converting electric energy is kinetic energy.
C section: B section only has dynamic flabellum and nothing determines flabellum, the air-flow that servo-actuated flabellum rotates around hollow spindle axis forms cyclone, because the density ratio of oxygen and nitrogen is 8/7, under the centrifugal action of cyclone, oxygen and nitrogen is made to have certain being separated, realize the screening effect of nitrogen oxygen, oxygen enters the part of calming the anger of D section from the O duct 145 of outer rim, nitrogen, from the first half hollow spindle of central authorities then N duct A section radial inflow forward, makes the oxygen content being entered rectangle air jet pipe by O duct significantly to increase.
D section: be provided with dynamic flabellum of calming the anger, determine the alternate structure of calming the anger of flabellum, dynamic flabellum of calming the anger is fixed on main shaft and relative main axis inclination angle is larger, determining flabellum is fixed on outer ring (being actually the main structure support of motor), the effect determining flabellum stops cyclone, generation because of the cyclone effect that can make to calm the anger is had a greatly reduced quality, therefore determines flabellum and the kinetic energy of cyclone can be further converted to air pressure energy.In addition, alternate the calming the anger number of plies that is dynamic, that determine flabellum can design as required, but after calming the anger, air pressure must much larger than 1 barometric pressure.The last one deck of flabellum group of calming the anger must be determine flabellum, and this another effect determining flabellum fixes rear end bearing outer hoop by oblique pull spoke silk.When air jet pipe flame accelerates flight, the fore bearing of main shaft mainly carries forward thrust, and the rear end bearing of main shaft just mainly carries to back pressure when flame-out glide.In addition, at rear end bearing place, speed probe 135 is also housed.
Power moves flabellum-----, and by hollow spindle (hollow parts is N duct leading portion), in order to calm the anger, dynamic flabellum provides energy, the power resources that power moves flabellum have two: 1, during low-speed operations, as the rotor of variable-frequency motor, by eddy current conduction band, obtain the energy of rotating magnetic field.2, during high-speed flight, as passive flabellum, utilize intake duct relative to the huge pressure reduction of N duct, absorption rate punching press energy.Flabellum-----of calming the anger adopts the structure between dynamic, phasing.Dynamic flabellum of calming the anger is fixed on rear cup-shaped main shaft.Must be finally determine flabellum, refer to: calm the anger flabellum from front to back order be, (dynamic, fixed ..., dynamic, fixed) or (fixed and moving ..., fixed and moving, fixed).
E section: the differential pressure pickup 125 being provided with the relative N duct 100 of O duct 145 and N duct 100 phase External Environment, differential pressure pickup 125 can adopt elastic force to be out of shape membrane type differential pressure pickup or elastic force piston tubular type differential pressure pickup.Man-machine for having, the passage being also provided with pressure-reducing function provides 1 atmospheric pressurising oxygen supplement function for cabin.Because E, F section is almost in position of centre of gravity, there is overall engine fixed end under the wings of an airplane the upside of motor, wherein includes circuit, oil circuit and gas circuit (having man-machine).If motor is contained in the both sides of fuselage, then without upside fixed end, the permanent magnet of G section then need not be contained in motor, but is contained on fuselage, as long as form the magnetic line of force (the giant single magnetic line of force) that can run through air jet pipe.
In addition, in front elevation: C segment body is dynamic flabellum now, and D segment body now determines flabellum.In side, plan view: moving, determine flabellum in the cup-shaped main shaft of B, D section is radially projecting, but not is in hollow spindle.
F section: the air inlet place of rectangle jet pipe, there is the Unidirectional air inlet valve that operating angle is identical, Unidirectional air inlet valve can be curtain, with gear, tooth bar (hanging with Returnning spring and photoelectrical position sensor), its role is to: the intake flow sensor preventing combustion gas anti-fire and rectangle jet pipe forward.
Respectively there are a pair fuel nozzle and igniting polar in the front portion (belonging to O duct 145) in rectangle air jet pipe up and down.Aviation gasoline injection pump 165 is also provided with between O duct, N duct.Energy-conservation in order to realize, can take some control programs by the signal of sensor sensing, the technology involved by these control programs is all technology of existing maturation, therefore does not repeat at this.
G section: be leptosomatic rectangle air jet pipe (can fuel saving Thorough combustion), the left and right sides be resistant to elevated temperatures insulating material, is wherein embedded with temperature inductance probe (platinum resistor as negative temperature coefficient), outside is the material (as silicon steel plate) that constraint imports the magnetic line of force.Upper and lower both sides are resistant to elevated temperatures conductive material, and upside is negative electrode, and downside is anode (arrange like this is because being with nuclear positive ion weight because electronegative free electron is light).Between upper magnet and minus plate, between lower magnet and positive plate, be equipped with heat insulation infrared external reflection plate, prevent high temperature pole plate from toasting permanent magnet demagnetization.The air-flow being mainly nitrogen in N duct both served thermolysis to permeability magnetic material, alleviated oxidation again.The electrode leads to client of pole plate also plays locking pole plate in front portion, prevents its igniting heat expansion, front and back that flame-out shrinkage causes wriggle and produce gap and leak combustion gas.In addition, the outer surface of fixing and locking everywhere and other each parts before and after rectangle jet pipe, because being in N duct, therefore only considering radiating effect and does not consider fairshaped aerodynamic force effect.Utilize the ionization phenomena of hot flame in air jet pipe, the deflection of moving charge in magnetic field, for gas compressor provides electric energy, and does not need turbine.In addition, the electric charge be separated can close counteracting by lotus root again, this is also harmless, can be considered a string direct current battery eliminator group, do not affect the total output W between pole plate output (just as the negative pole of the last battery of battery pack connects with the positive pole of a rear battery, though positive and negative charge lotus root close offset, the power stage not affecting integral battery door group is the same, this be visualization liken, and there is not real battery pack).The Equivalent Calculation formula of negative electrode and positive plate electric energy output power W: W=rectangular nozzle inner volume (=polar plate area × distance between plates is from cross-section area × jet pipe length in=pipe) vertical magnetic field strength × jet pipe flame temperature in × jet pipe
r(test of 2<R empirical index number is undetermined).
In fact, except jet pipe and near high-temperature zone, main shaft bearing, eddy current conduction band, winding circuit place, all can adopt this high strength plastic materials.Both reduce cost of material significantly like this, the locating and tracking of hostile electromagnetic wave reflection radar can be prevented again.
Motor provided by the invention can miniaturization, thus can use on unmanned plane; It saves the feature of fuel oil, and the cruise time of unmanned plane can be made to extend; The feature that its cost reduces, can make unmanned plane produce by batch in a large number; Above-mentioned feature can make China's unmanned plane field occupy an leading position in the world.
