Abstract

The invention relates to a transverse course control system and a transverse course control method for flying wing configuration. For flying wing configuration planes, due to the removal of vertical tails and horizontal tails, the flight efficiency is significantly improved, and the detection performance is low, however the transverse course control ability is poor. Existing transverse course control methods employing differential flaperons, full motion wingtips, spoilers inside and outside wings and other flying wing configuration are low in control efficiency and complex to control, and the poor mobility restricts the development and use of flying wing configuration planes. The transverse course control system consists of: a flying wing configuration plane (1) and a movable handpiece control plane (2). The movable handpiece control plane is a flat handpiece, and is connected to the body of the flying wing configuration plane through an internal driving mechanism. The system and the method provided by the invention can be used for transverse course control of flying wing configuration planes.

Description

Technical field:
The present invention relates to a kind of horizontal course control system of Flying-wing and horizontal course heading control method.
Background technology:
From the development of aircraft with develop from the point of view of, for improving the fuel efficiency of aircraft, obtain high lift-drag ratio, Flying-wing is Best aircraft configuration selects.Fuselage and wing are combined by Flying-wing's aircraft, and eliminate vertical fin and Horizontal tail is so as to have the unique advantage that profile is gently smooth, pneumatic efficiency is high and detectivity is very low.Disclosed money abroad Material shows that the maximum lift-drag ratio of Flying-wing can reach 25~30, and its liter of the high aspect ratio civil aircraft of conventional in layout hinders Than general 17~20 about;Simultaneously because eliminating the construction weight more than 5% that empennage part can reduce aircraft, few Vertical tail peace tail piece again can drag reduction 10% about (reducing frictional resistance and part interference drag).Thus aircraft can be made Time related cost (doc) reduce by more than 30%, the cruising time of aircraft, voyage can be greatly improved simultaneously and effective carry Lotus, is greatly improved the pneumatic efficiency of aircraft.
Flying-wing's aircraft has many advantages, such as above-mentioned, but its shortcoming is also clearly, due to not having the horizontal tail of routine and hanging down Tail, it is even unstable that horizontal course is in neutral static-stability, shows particularly evident in supersonic flight.Aircraft keeps steady in the air Fixed flight needs to keep the power of six degree of freedom and the balance of moment, when needing to change aspect, is such as turned or bows Then certain angle is deflected by primary control surface when facing upward and produce aerodynamic force, this aerodynamic force produces moment around the center of gravity of airplane and changed Become attitude, again reach balance when reaching a certain attitude around the power of the center of gravity of airplane and moment.The conventional airplane of normal configuration It is to produce rolling moment around aircraft longitudinal axis using the deflection of wing aileron when turning, the deflection of utilization orientation rudder simultaneously comes The unfavorable moment in course that balance is brought due to sideslip, thus realize quick direction controlling.And Flying-wing is not due to having vertical tail And horizontal tail, thus its horizontal shipping-direction stability and handling characteristic are poor, in the case of meeting high speed crosswind, have and lead to aircraft roll With the danger entering tailspin.
At present the main horizontal course heading control method of Flying-wing has using the pitching wing flap on wing, elevon, inside and outside Side spoiler, ' clamshell style ' device, interior Outboard Leading Edge Flap, entirely move wing tip, differential droope snoot, split spoiler, folding Stream plate, folding and unfolding rudder and lower surface spoiler etc. can intercouple the side force of generation and moment carrying out the control of horizontal course System, or the asymmetric edge strip using head, edge strip crack etc. generation faint asymmetric side force carrying out Flying-wing's aircraft Horizontal Heading control, because wing itself is close to position of centre of gravity, lead to and inefficiency complicated to the control method of aircraft.
Due to eliminating vertical fin, Flying-wing's aircraft has higher Stealth Fighter and high lift-drag ratio (flies for Flying-wing Line efficiency is high), but its cost paid is serious shipping-direction stability and horizontal Heading control problem.Conventional airplane is when turning It is deflection one side force of generation and the yawing of utilization orientation rudder first, utilize aileron to produce a favourable rolling power simultaneously Realizing quick direction controlling, due to not having vertical tail and horizontal tail, flaperon is apart from center of gravity position simultaneously for Flying-wing for the coupling of square Put relatively near, thus its horizontal directional control characteristic is poor.
Or the horizontal course heading control method rudder face coupling of above-mentioned Flying-wing aircraft is complicated, Flight Control Law difficult design, Control efficiency is relatively low, leads to the mobility of aircraft poor, thus existing Flying-wing is mainly used in air-to-ground attack and bangs On aircraft bombing class aircraft.
For the aircraft of Flying-wing, when due to but having fallen vertical tail and horizontal tail, flight efficiency significantly improves, to have low simultaneously Detectable performance, but the control ability in its horizontal course is poor, existing using differential flaperon, entirely move wingtip, outside in wing The crosswise joint method control efficiency of the Flying-wings such as spoiler is low, it is complicated to manipulate, thus mobility is poor, constrains all-wing aircraft The development of airplane and use.
Content of the invention:
It is an object of the invention to provide a kind of horizontal course control system of Flying-wing and horizontal course heading control method.
Above-mentioned purpose is realized by following technical scheme:
A kind of horizontal course control system of Flying-wing, its composition includes: Flying-wing's aircraft, mobilizable head rudder Face, described movable head rudder face is pancake head, described movable head rudder face and described Flying-wing's aircraft Body connected by internal driving mechanism.
