Description

A kind of target drone aerodynamic arrangement

Technical field

The utility model relates to a kind of target drone aerodynamic arrangement, belongs to aerodynamic configuration of aircraft technical field.

Background technology

Target refers to the dynamic physical object simulating device of the one of the target that various armament systems will be attacked.It is used for checking the performance characterisitic of whole armament systems, comprising weapon itself and mainly form subsystem, as the combination property of guided missile, radar, optical tracker, launch control system etc.Therefore, require from Weapon System Development and from Armed Forces' training, all require that target is true to nature in real goal as much as possible in various performance.Target drone is the one of target, generally dynamic aerial target is nominally target drone, and target drone, except special equipment on some machine, all uses similar technology to unmanned vehicle.

Domestic target drone development and production have the history of nearly 50 years, comprise entity target drone, large high-speed target drone, small-sized low-altitude low-speed target drone, target missile etc., through the development of ISUZU company, the aerial target of China formed vast sky series, target-5 second, destroy and-6 to change, destroy the large-scale target drone series that-7 change representative into, B-2 and B-7 is the small-sized target series of representative, supports qualification test and the military training of domestic air-to-air armament system, land-air weapon system.This type of target drone product can only simulate two generation operational aircraft target property, due to design time comparatively early, the potentiality improving remodeling are also very limited.The aerodynamic arrangement of " No. one, vast sky " target drone belongs to typical normal configuration: rectangle midsetwing, and elongated rotary body fuselage, head and afterbody are parabolic shape fairing.

Military power is all greatly developing variety classes, advanced in performance target, and existing nearly 30 national over one hundred companies develop 300 Multiple Types so far, and equipment uses total amount to reach several ten thousand framves.The particularly U.S., aerial target A wide selection of colours and designs, One's name is legion, simulates true to nature, has become that aerial target quantity is in the world maximum, the state-of-the-art country of performance, and representative model be that " chukar ", " fiery honeybee " are serial.The aerodynamic arrangement of " fiery honeybee " target drone belongs to typical normal configuration: sweepback midsetwing, elongated rotary body fuselage.

Aerodynamic arrangement's design is the emphasis of Aircraft Conceptual Design, directly has influence on the comprehensive serviceability of aircraft.Existing target drone many employings normal configuration, low aspect ratio wing, this layout belongs to typical second generation jet plane aerodynamic arrangement, and (first generation jet plane is the aircraft of original adoption jet engine, propeller aeroplane performance comparatively has qualitative leap, and second generation jet plane promotes in speed, ceiling, acceleration, power of climbing to some extent at first generation jet plane) bias toward high-altitude, characteristic at a high speed.The functional limitation existed is as follows:

1) high-angle-of-attack flight ability.The aerodynamic arrangement of existing target drone does not have high-angle-of-attack flight ability, and flying angle is below 15 °.(angle of attack: the angle at any time formed between aircraft and wind speed direction)

2) maneuvering flight ability.Existing target drone design point biases toward the characteristic of high-altitude, high speed, and maneuverability is generally not enough.(maneuvering flight ability: the ability of change of flight state in-flight, can adopt overload to characterize).

Summary of the invention

The purpose of this utility model is to provide a kind of target drone aerodynamic arrangement, to promote maneuvering characteristics and the high-angle-of-attack flight ability of target drone aerodynamic arrangement.

For achieving the above object, the utility model have employed following technical proposals: a kind of target drone aerodynamic arrangement, comprises fuselage, vertical fin, horizontal tail, wing, edge strip and air intake duct, and fuselage requires according to internal placement and determines its profile; Air intake duct determines its profile according to the Air intake characteristics of engine, it is characterized in that, wing adopts maximum gauge to be the laminar flow airfoil of 6.5% ~ 10%, and horizontal tail adopts maximum gauge to be the symmetrical airfoil of 4% ~ 8%; Vertical fin adopts maximum gauge to be the symmetrical airfoil of 4% ~ 8%, edge strip adopts the elongated arch of large sweepback, and the leading edge shape of edge strip is wedge shape, and edge strip angle of sweep adopts between 70 ° ~ 76 °, edge strip area is 5% ~ 10% of wing area, and edge strip length is 20% ~ 28% of wing length.

The low aspect ratio wing that the utility model has air inlet for high angles of attack flight and edge strip before adopting, two nothings turn to, the fuselage of optimizing pneumatic characteristic and one have thin wing and plane of bending, horizontal tail and vertical fin, improve maneuvering characteristics and the high-angle-of-attack flight ability of target drone greatly.
