Abstract

A prey bird type tail of the wing-fixed airplane features that the force or force moment acting on the longitudinal axis X of airplane is generated by the active drive units (motor) controlled by servo mechanism (steering machine), so controlling the fly direction, vector, and auxiliary power.

Description

Prey-bird machine tail

The design's design is a kind of aerodynamic arrangement that is applicable to model airplane or SUAV (small unmanned aerial vehicle).Overcome the complex structure of conventional in layout, passive generation moment is moved shortcoming such as single, is the design concept that a kind of utmost point has promotional value.

In present known empty mould (the referring to fixed wing aircraft) aerodynamic arrangement, be that rudder face is the angle of vertical tail vane and produces the deflecting torque that acts on the aircraft X longitudinal axis under the effect of air-flow on the vertical tail by changing, realize directional control aircraft.Its defective is significantly, one, and only when aircraft flight moved, its vertical tail vane was at the effect lower stress of air-flow, and when flying speed was very low, the effect of vertical tail vane was very little or does not exist.At above defective design concept a kind of aircraft tail following advantage is arranged: but a positive force realizes that the course that aircraft is implemented in the plane that the X longitudinal axis and Z transverse axis form is controlled; Two, can realize vector controlled in the plane of the aircraft X longitudinal axis and Z transverse axis composition, this is a kind of application of vector controlled on model airplane; Three, can realize effect to the auxiliary power or the resistance of aircraft.Be to achieve many things at one stroke.

See accompanying drawing, Fig. 1, Fig. 2, Fig. 3 are the airplane tail group birds-eye view.Small size motor and minor spiral oar by rotating shaft fixing with the airplane tail group beam on (small size motor can rotate and its rotational angle be controlled by steering wheel along rotating shaft), when minor spiral oar plane of revolution is parallel to the plane that the X longitudinal axis and Y vertical shaft formed perpendicular to the Z transverse axis, the forward or reverse of minor spiral oar can be realized the control for vector, as shown in Figure 1.When the angle theta on the plane that minor spiral oar plane of revolution and the X longitudinal axis and Y vertical shaft are formed is spent less than 90 with 0 degree greatly or greater than 90 degree, spending less than 180, forward or reverse by the minor spiral oar can make aircraft be implemented in vector controlled in the plane that the X longitudinal axis and Z transverse axis form, as shown in Figure 2, this is as magical vector controlled as the Soviet Union-30.Three, when the flat X longitudinal axis with aircraft of minor spiral oar plane of revolution is vertical, the propelling thrust of minor spiral oar plays the effect of auxiliary power to aircraft flight, and the application force when minor spiral reverses can play the effect of resistance again, is to achieve many things at one stroke.

The essence of the design's design is to install rotatable positive force device on the stern framing of fixed wing aircraft additional, has realized course control respectively, vector controlled, auxiliary power and resistance control.Its main power plant can be that electrical motor also can be that combustion engine divides power, and same available other servomechanism of steering wheel replaces, but the design's design should only be applicable to sky mould or SUAV (small unmanned aerial vehicle).

Claims

1, a kind of fixed wing aircraft tail acts on the power or the moment of the aircraft X longitudinal axis by generation such as motor of servomechanisms such as steering wheel control positive force, reaches to vector vector, the purpose that auxiliary power is controlled.Its technology is applicable on model airplane or the SUAV (small unmanned aerial vehicle).

2, set forth according to specification sheets, its principal character is the plane of revolution by the minor spiral oar of servomechanisms such as steering wheel control afterbody positive force, produces the power that acts on the aircraft X longitudinal axis or moment and realizes manipulation to aircraft.

3, the generation power of its moment must be that the power output of electrical motor or combustion engine causes, rather than the passive airflow acting force of aircraft flight that is subjected to causes.

4, the angle of the plane of revolution of application of force minor spiral oar and the aircraft X longitudinal axis be 0 spend to 180 the degree variable.

5, small size motor and other engine installation of the control application of force are steering wheel or other actuating device.

6, this aircraft tail can be realized vector control, vector controlled, auxiliary power control and resistance control.
