Detailed description of the invention
The utility model provide a kind of individual gas sources air feed without rudder face aircraft, its structure as shown in Figure 1, Figure 2 and Figure 3, comprise the canard configuration's Fixed Wing AirVehicle be made up of fuselage 5, host wing 3, canard 6, back-pushed engine installation 7, screw propeller 8, winglet 11, main landing gear 12 and nose-gear 13, host wing inside is provided with circulation control device, the control that can conventional aileron and elevating rudder not relied on to realize rolling and pitch attitude, realizes flying without rudder face.
Circulation control raise/lower actuator is made up of a multi-wing centrifugal fan 2 and a jet pipe 1, wherein multi-wing centrifugal fan 2 is as an independently source of the gas, by multi-wing centrifugal fan motor 9 from wing tip bleed, provide high-voltage high-speed airflow, jet pipe makes air-flow deflect for the formation of Coanda effect.The side of jet pipe 1 connects multi-wing centrifugal fan 2, and opposite side is elongated coanda trailing edge, and trailing edge radius is 4.5mm, and what trailing edge place had a 300mm to grow goes out air cleft, and the ratio that trailing edge radius is high with going out air cleft is 15, stitches high 0.3mm as shown in Figure 4.Because the inner space of aircraft wing is limited, for the ease of jet pipe is imbedded wing inside, the upper sealing surface 15 of jet pipe and lower sealing surface 16 shrink junction in 15 ° of angles from centrifugal blower interface to coanda trailing edge, its thickness be 1mm as shown in Figure 5.Loss of pressure is caused in order to prevent cross-sectional expansion, cause jet energy not enough, the configuration design of jet pipe is carried out one according to following steps and from centrifugal blower interface, is equidistantly chosen 5 cross sections until the area in these 5 cross sections is decided to be i.e. 15.5mm × 70mm consistent with admission port area by coanda trailing edge two, determine the cross section transverse width that the transverse width three needed for lower each cross section is fixed according to second step, smooth connection boundary point successively, obtain profile shown in Fig. 6, two N-Side surf thickness are 1mm.In order to make to give vent to anger evenly, jet pipe inside is provided with deflecting plate 18, and inner chamber is divided into 5 regions by the curved shape of flow deflector, and the thickness of flow deflector is 1mm, is being provided with rounding, as shown in Figure 7 close to admission port place.In order to complete the function the same with rudder face, air-flow is made to occur to deflect up and down, jet pipe is designed to up and down independently two parts by the utility model from admission port, separated by the one flat plate at middle part, upper and lower two parts cavity volume is equal, see Fig. 8, when providing the centrifugal blower rotor turns of source of the gas for the latter half pipeline, outer gas stream is inhaled into the latter half pipeline, this strand of air-flow can upward deflect along circular coanda trailing edge from when going out air cleft injection, same principle, when providing the centrifugal blower rotor turns of source of the gas for the first half pipeline, outer gas stream is inhaled into the first half pipeline, this strand of air-flow can deflect down along circular coanda trailing edge from when going out air cleft injection.Final centrifugal blower with jet pipe combination after as shown in Figure 9.
Circulation control aileron exiter, for replacing aileron, realizes the control of roll attitude.Usual conventional rudder face realizes this control by differential deflection, of the present utility modelly causes left and right lift overbalance to realize the manipulation of roll attitude without rudder face aircraft by opening the circulation control aileron exiter of side.The essential structure of circulation control aileron exiter is similar to circulation control raise/lower actuator, but only have a cavity and one to go out air cleft, by a centrifugal blower air feed, the air-flow of trailing edge can be made to deflect down, increase the circular rector of side wing, realize the object of lift-rising.Circulation control aileron exiter 4 width of these works design is 240mm, and trailing edge radius 4.5mm, goes out air cleft height 0.3mm, as shown in Figure 10.
Flight attitude control principle without rudder face aircraft of the present utility model is: after input control signal, multi-wing centrifugal fan is started working, under the effect of centrifugal impeller, wing internal gas flow is accelerated, eject through jet pipe, utilize Coanda effect to be formed with profit interference to main flow air-flow, the aerodynamic force acting on wing can be changed.Based on above-mentioned principle, the circulation control aileron exiter opening side produces the not reciprocity control realizing roll attitude of left and right airfoil lift, deflect down air-flow by the circulation control raise/lower actuator controlling fuselage both sides and produce nose-down pitching moment, upward deflect air-flow by circulation control raise/lower actuator and produce nose-up pitching moment.When the circulation control raise/lower actuator of fuselage side is opened up and down while during blow mode, can yawing moment be formed, make aircraft toward the side driftage of not opening air blowing.
The utility model is configured as canard configuration, eliminates traditional rudder face, is embedded in the circulation control device of wing in the substitute is, all the other structures and conventional airplane similar, structure is simple, is convenient to safeguard.Owing to eliminating conventional rudder face, the original sharp edges of aerofoil surface, opening and boss etc. can disappear, and this, by reducing the radar scattering area of aircraft, can promote the stealth of aircraft.The utility model has completed a frame without rudder face aircraft material object, and it has been carried out to wind tunnel experiment and the Flight Test Research of system.Wind tunnel experimental results shows, this under 10m/s wind friction velocity, can produce commensurateiy wide aileron 50 ° of inclined effects of rudder and 20 ° of inclined effects of elevating rudder rudder without rudder face aircraft.According to result of taking a flight test, the circulation control device of the utility model design can proportional control attitude, and aircraft is very steady in flight course, takes a flight test very smooth without rudder face.
Below the basic specification in kind that the utility model has completed:
