Abstract
The utility model relates to the field of aerial vehicles, and provides an annular blown flap ducted aerial vehicle, wherein an upper-part ducted shell and a lower-part umbrella housing are connected together by reinforced ribs to form the main structure of the aerial vehicle, an upper-part propeller and a lower-part propeller are arranged inside the lower-part umbrella housing respectively by an annular member, and a control plane is arranged at the lower part of the lower-part umbrella housing by a hinge; and an undercarriage is arranged on the annular member at the bottom of the lower-part umbrella housing through a hoop. According to the annular blown flap ducted aerial vehicle, the upper-part ducted shell generates a part of lifting force so as to accelerate and rectify air flow at the same time, a part of air flow in an upper-part duct can flow downward through an inner duct, the other part of air flow is cut by the upper end of the umbrella housing, and fast flows down along the umbrella housing due to adsorption effect of a border layer, and the special curvature of the umbrella housing enables the air flow to generate additional lifting force, thereby further improving the lifting force efficiency.
Description
Technical field
The utility model relates to aircraft and relates to the field, relates in particular to a kind of annular blown flap duct aircraft.
Background technology
The duct aircraft itself has many good qualities, and can produce larger lift such as the fan of same size, and fan is wrapped in the duct, thus noise little, avoid collision.But because fan and duct shell dimension less, in order to produce larger lift, downwash speed is fast, so power consumption is large, and lift efficient is low, and cruise duration is short.
The utility model content
The technical problems to be solved in the utility model: further promote its pneumatic efficiency, the miniature duct aircraft when designing large lift, high load-carrying, long boat.
The technical solution of the utility model: annular blown flap duct aircraft of the present utility model, top duct housing and bottom umbrella shape shell are reinforced rib and link together, the keystone configuration that forms this aircraft, top screw propeller and bottom screw propeller respectively are installed on the inside of bottom umbrella shape shell by annular element, the control rudder face is installed on the bottom of bottom umbrella shape shell by hinge; Alighting gear is installed on the base circle member of bottom umbrella shape shell by clip.
The beneficial effects of the utility model: top duct housing produces a part of lift, simultaneously air-flow is played the effect of speedup and rectification, the air-flow part of top duct flows downward by main duct, a part is by the cutting of umbrella shape housing upper end, because boundary 1ayer adsorption effect, flow downward fast along the umbrella shape shell, the special curvatures of umbrella shape shell has been so that air-flow has produced extra lift, and then improved lift efficient.

Fig. 1 is the utility model annular blown flap duct Flight Vehicle Structure scheme drawing.
Fig. 2 is the utility model annular blown flap duct aircraft lift-rising principle schematic.
Fig. 3 is the utility model annular blown flap duct aircraft top duct housing profile scheme drawing.
Fig. 4 is the utility model annular blown flap duct aircraft bottom umbrella shape shell profile scheme drawing.
The specific embodiment
As shown in Figure 1, feature of the present utility model is: mainly be comprised of top duct housing 1, strengthening rib 7, top screw propeller 2, bottom umbrella shape shell 3, bottom screw propeller 4, control rudder face 5, alighting gear 6.
Annular blown flap duct aircraft of the present utility model, brief overview is exactly on the basis of conventional duct aircraft, installs a umbrella shape shell additional as high lift device below its duct, further improves lift efficient, bear lift-rising, synergistic effect, be referred to as annular blown flap.Top duct housing 1 and bottom umbrella shape shell 3 are reinforced rib 7 and link together, the keystone configuration that forms this aircraft, top screw propeller 2 and bottom screw propeller 4 respectively are installed on the inside of bottom umbrella shape shell 3 by annular element, control rudder face 5 is installed on the bottom of bottom umbrella shape shell 3 by hinge.Alighting gear 6 is installed on the base circle member of bottom umbrella shape shell 3 by clip.
As shown in Figure 2, the utility model top duct housing produces a part of lift, simultaneously air-flow is played the effect of speedup and rectification, the air-flow part of top duct flows downward by main duct, a part is by the cutting of umbrella shape housing upper end, because the boundary 1ayer adsorption effect flows downward fast along the umbrella shape shell, the special curvatures of umbrella shape shell has been so that air-flow has produced extra lift, and then improved lift efficient.
Top of the present utility model duct housing 1 and bottom umbrella shape shell 3 have special profile, as shown in Figure 3 and Figure 4.
Topside mainly forms main load-carrying construction by 18 common ribs, 6 strengthening ribs and 3 annular girder members, and the outside is covered with cork wood illiteracy plate and pyrocondensation covering and kept aerodynamic configuration.Common rib adopts the deal board of thick 2mm, and annular girder is the laminate of thick 2mm.Each member all has lightening hole.
The bottom keystone configuration is similar with the top structure, forms main load-carrying construction by 18 common ribs, 6 strengthening ribs and 5 annular girder members, and the outside is covered and kept aerodynamic configuration with the pyrocondensation covering.Wherein have 2 annular girder members to bear the effect of mounted motor, the annular girder of bottommost is born the effect that alighting gear is installed.With the top structure different be, also have a main duct in the inside of bottom section, engine installation is installed---motor and screw propeller.
Complete machine plays the effect that connects the upper and lower structure along circumferentially being evenly equipped with 6 strengthening ribs, and larger area web plays the effect of combing by-pass air duct air-flow in the middle of it, can offset a part of reactive torque.Strengthening rib is that the laminate of thick 3mm is made.
This machine alighting gear by aluminum tube bending, be welded, at four " pin " of alighting gear the foam shock-absorbing ball is installed, play buffer action.The elastic deformation of alighting gear aluminum pipe also can be offset a part of landing impact force.This alighting gear is installed on the annular girder of bottom section.
The machine adopts double-motor, twin screw, contrarotation design trim moment of torsion.By the throttle curve of two motors independently is set, make two cover motors basic synchronization in whole range of speed in remote control equipment (RCE); By the fine setting rudder face, reached and controlled preferably effect again.
Because the main duct air-flow velocity is large, driving efficiency is high, and the primary control surface of this machine is arranged in the bottom of main duct.Rudder face is divided into 2 groups 3, and wherein 2 less rudder faces are controlled respectively by 2 steering wheels, can differential deflection, thus can control slewing maneuver around axis of symmetry; The synchronous deflection of larger control surface deflection and two little rudder faces can realize respectively the pitch control of both direction.
Claims (1)
