Further, the area ratio of wing aileron and wing main wing is 0.124, the area ratio of empennage aileron and empennage main wing
For 0.313.
The positive effect of the utility model is：
1st, using target drone fuselage, air intake duct, wing and empennage as an overall processing, due to need to only consider main portion
The abutting joint divided, it is only necessary to which bonding or screw are fixed, it is not necessary to do fuselage, wing and empennage assembly jig again.By with
Upper measure, not only cylinder block strength is met the requirements, and whole body adds flying reliability without weak load-bearing point.With tradition
Processing method compares, and production cycle and processing cost respectively reduce more than 50%, and weight reduces by 12% (10kg), is disposably assembled into
Power brings up to more than 99% by 85% or so.The reduction of body weight can be converted directly into the load incrementss of target drone,
The cruising time of target drone can be made to increase to 50min by original 40min indirectly by increasing fuel load.
2nd, this target drone fuselage is made of fiberglass and carbon fibre composite, has both overcome single glass Steel material without electricity
The shortcomings of magnetic screen function and carbon fibre material are of high cost, coloring is difficult, while the weight of fiberglass and carbon fiber is maintained again
Gently, the characteristic such as high intensity, corrosion-resistant, high temperature resistant.
3rd, in the case where aerodynamic configuration is constant, housing construction intensity and weight the maximum flying speed of target drone,
The air inlet of this target drone air intake duct uses the rectangular design of 80mm × 120mm, increases unit interval air inflow, improves and start
Machine work efficiency and maximum thrust, make the target drone max level speed bring up to 200m/s by 180m/s.
4th, target drone weight saving and the increase of air intake duct area, are more advantageous to target drone maneuvering, wing aileron and wing
The area of main wing than by original 0.118 increase till now 0.124, add 5%, the area of empennage aileron and empennage main wing
Than by original 0.291 increase till now 0.313, add 7%；Change target drone flies to control corresponding program accordingly at the same time, makes target
Machine latitude bigger, overload capacity are 4g by original 3g increases.
